BackgroundMajor depressive disorder (MDD) is associated with an increased risk of brain atrophy, aging-related diseases, and mortality. We examined potential advanced brain aging in MDD patients, and whether this process is associated with clinical characteristics in a large multi-center international dataset.MethodsWe performed a mega-analysis by pooling brain measures derived from T1-weighted MRI scans from 29 samples worldwide. Normative brain aging was estimated by predicting chronological age (10-75 years) from 7 subcortical volumes, 34 cortical thickness and 34 surface area, lateral ventricles and total intracranial volume measures separately in 1,147 male and 1,386 female controls from the ENIGMA MDD working group. The learned model parameters were applied to 1,089 male controls and 1,167 depressed males, and 1,326 female controls and 2,044 depressed females to obtain independent unbiased brain-based age predictions. The difference between predicted “brain age” and chronological age was calculated to indicate brain predicted age difference (brain-PAD).FindingsOn average, MDD patients showed a higher brain-PAD of +0.90 (SE 0.21) years (Cohen’s d=0.12, 95% CI 0.06-0.17) compared to controls. Relative to controls, first-episode and currently depressed patients showed higher brain-PAD (+1.2 [0.3] years), and the largest effect was observed in those with late-onset depression (+1.7 [0.7] years). In addition, higher brain-PAD was associated with higher self-reported depressive symptomatology (b=0.05, p=0.004).InterpretationThis highly powered collaborative effort showed subtle patterns of abnormal structural brain aging in MDD. Substantial within-group variance and overlap between groups were observed. Longitudinal studies of MDD and somatic health outcomes are needed to further assess the predictive value of these brain-PAD estimates.FundingThis work was supported, in part, by NIH grants U54 EB020403 and R01 MH116147.

Aims Although of great value to understand the treatment results for mental health problems obtained in clinical practice, studies using naturalistic data from children and adolescents seeking clinical care because of complex mental health problems are limited. Cross-national comparison of naturalistic outcomes in this population is seldomly done. Although careful consideration is needed, such comparisons are likely to contribute to an open dialogue about cross-national differences and may stimulate service improvement. The aim of this observational study is to investigate clinical characteristics and outcomes in naturalistic cohorts of specialized child and adolescent mental health outpatient care in two different countries. Methods Routinely collected data from 2013 to 2018 of 2715 outpatients in the Greater Area of Brisbane, Australia (CYMHS) and 1158 outpatients in Leiden, the Netherlands (LUMC-Curium) were analysed. Demographics, clinical characteristics and severity of problems at start and end of treatment were described, using Children's Global Assessment Scale (CGAS), Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) and the parental Strength and Difficulties Questionnaire (SDQ-P). Results Routine outcome measures (CGAS, HoNOSCA, SDQ-P) showed moderate to severe mental health problems at start of treatment, which improved significantly over time in both cohorts. Effect sizes ranged between 0.73-0.90 (CYMHS) and 0.57-0.76 (LUMC-Curium). While internalizing problems (mood disorder, anxiety disorder and stress-related disorder) were more prevalent at CYMHS, externalizing developmental problems (ADHD, autism) prevailed at LUMC-Curium. Comorbidity (>1 diagnosis on ICD10/DSM-IV) was relatively similar: 45% at CYMHS and 39 % at LUMC-Curium. In both countries, improvement of functioning was lowest for conduct disorder and highest for somatoform/conversion disorders and obsessive-compulsive disorders (OCD). Overall, 20-40% showed clinically significant improvement (shift from clinical-range at start to a non-clinical-range at the end of treatment), but nearly half of patients still experienced significant symptoms at discharge. Conclusions This large-scale outcome study showed both cohorts from Australia and the Netherlands improve during the course of treatment on clinician- and parent-reported measures. Although samples were situated within different contexts and differed in patient profiles, they showed similar trends in improvement per diagnostic group. While 20-40% showed clinically significant change, many patients experienced residual symptoms reflecting increased risk for negative outcome into adulthood. We emphasize cross-national comparison of naturalistic outcomes faces challenges, although it can similarly reveal trends in treatment outcome providing direction for future research: what factors determine discharge from specialized services; and how to improve current treatments in this severely affected population.

Cross-sectional Diffusion Tensor Imaging (DTI) studies have reported alterations in white matter (WM) microstructure in adolescents with internalizing psychopathology. Yet, longitudinal studies investigating the course of WM microstructure are lacking. This study explored WM alterations and its relation to clinical symptoms over time in adolescents with internalizing disorders. DTI scans were acquired at baseline and after three months in 22 adolescents with clinical depression and comorbid anxiety (INT), and 21 healthy peers (HC) (age: 12-18). Tract-based spatial statistics was used for three voxelwise analyses: i) changes in WM microstructure between and within the INT and HC group; ii) associations between changes in symptom severity and changes in WM microstructure within youths with INT; and iii) associations between baseline WM parameters with changes in symptom severity within youths with INT. Data did not reveal changes in WM microstructure between or within groups over three months' time nor associations between changes in WM microstructure and changes in self-reported symptoms (analyses corrected for age, gender and puberty stage). Lower baseline levels of fractional anisotropy (FA) in the right posterior corona radiata (PCR) and right cingulum were associated with a higher decrease of depressive symptoms within the INT group. Post hoc analysis of additional WM parameters in the significant FA clusters showed that higher levels of baseline mean diffusivity and radial diffusivity in the PCR were associated with a lower decrease in depressive symptoms. Baseline WM microstructure characteristics were associated with a higher decrease in depressive symptoms over time. These findings increase our understanding of neurobiological mechanisms underlying the course of internalizing disorders in adolescents.

A growing number of studies have examined alterations in white matter organization in people with posttraumatic stress disorder (PTSD) using diffusion MRI (dMRI), but the results have been mixed, which may be partially due to relatively small sample sizes among studies. Altered structural connectivity may be both a neurobiological vulnerability for, and a result of, PTSD. In an effort to find reliable effects, we present a multi-cohort analysis of dMRI metrics across 3,047 individuals from 28 cohorts currently participating in the PGC-ENIGMA PTSD working group (a joint partnership between the Psychiatric Genomics Consortium and the Enhancing NeuroImaging Genetics through Meta-Analysis consortium). Comparing regional white matter metrics across the full brain in 1,426 individuals with PTSD and 1,621 controls (2174 males/873 females) between ages 18–83, 92% of whom were trauma-exposed, we report associations between PTSD and disrupted white matter organization measured by lower fractional anisotropy (FA) in the tapetum region of the corpus callosum (Cohen’s d=−0.11, p=0.0055). The tapetum connects the left and right hippocampus, structures for which structure and function have been consistently implicated in PTSD. Results remained significant/similar after accounting for the effects of multiple potentially confounding variables: childhood trauma exposure, comorbid depression, history of traumatic brain injury, current alcohol abuse or dependence, and current use of psychotropic medications. Our results show that PTSD may be associated with alterations in the broader hippocampal network.

Background:Many children and adolescents experience violent events which can be associated with negative consequences for their development, mental health, school, and social functioning. However, findings between settings and on the role of gender have been inconsistent. This study aimed to investigate cross-country and gender differences in the relationship between community violence exposure (CVE) and school functioning in a sample of youths from three countries.Methods:A self-report survey was conducted among school students (12–17 years old) in Belgium (Antwerp,N= 4,743), Russia (Arkhangelsk,N= 2,823), and the US (New Haven,N= 4,101). Students were recruited from within classes that were randomly selected from within schools that had themselves been randomly selected (excepting New Haven, where all students were included). CVE was assessed with the Screening Survey of Exposure to Community Violence. School functioning was assessed with four measures: the Perceived Teacher Support scale, Negative Classroom Environment scale, and Academic Motivation and Perception of Safety at School scales. Multivariate Analyses of Covariance were performed to assess differences in the levels of school-related problem behaviors in boys and girls, who reported different degrees of CVE.Results:Participants in all three countries reported a relatively high prevalence of violence exposure (36.2% in Belgium, 39.3% in Russia and 45.2% in the US who witnessed violence), with a higher proportion of girls than boys witnessing violent events (varied from 37.4 to 51.6% between the countries), whereas boys reported more episodes of victimization by violence than girls (varied from 32.3 to 49.9% between the countries). Youths who experienced increased CVE (from no exposure to witnessing to victimization) reported an increase in all school functioning problems in all of the countries and this association was not gender-specific.Conclusions:Our findings suggest that regardless of differences in the level of CVE by country and gender, violence exposure is negatively associated with school functioning across countries. Nonetheless, even though reactions to community violence among adolescents may be expressed in a similar fashion, cross-country differences in social support systems should also be taken into account in order to provide culturally sensitive treatment modalities.

Background An open group climate is essential in successful residential care for juveniles with mild intellectual disability (MID). This study examined whether non-violent resistance, adapted for MID (NVR-MID), stimulates an open group climate in time. Method NVR-MID was implemented in three residential settings in The Netherlands, in a quasi-experimental stepped wedge design. In total, 124 clients with MID (Mage = 16.39 [SD = 4.95], 49.9% male) participated. Group climate was assessed seven times with the Group Climate Inventory for Children or the Group Climate Inventory-Revisited (GCI-R), during a total of 20 months. Results Open group climate scores increased in all three institutions; effect size was medium. Clients with lower IQs experienced group climate as more positive compared to clients with higher IQs. Effects were similar for both groups. Conclusions As NVR-MID appeared to contribute to a positive experienced group climate, it might be advisable to implement NVR-MID on larger scale.

Background: A dimensional approach of psychopathology focuses on features and risk factors that are shared across diagnoses. In support for this dimensional approach, studies point to a general psychopathology factor (GPF) associated with risk for multiple psychiatric disorders. It is, however, unknown how GPF relates to white matter integrity (WMI). In the current diffusion tensor imaging (DTI) study, we examined how GPF relates to abnormalities in a skeleton representation of white matter tracts, taking into account a trans-diagnostic risk factor: unresolved-disorganized attachment (Ud) resulting from loss or trauma. Methods: Unique associations between GPF, Ud, and WMI were examined in a combined sample of adolescents (N = 63) with childhood sexual abuse-related posttraumatic stress disorder (N = 18), anxiety and depressive disorders (N = 26) and without psychiatric disorder (N = 19). WMI was measured using DTI. Ud was measured using the Adult Attachment Interview. We controlled for puberty stage, gender, age, and IQ. Results: Controlling for GPF, Ud was associated with reduced fractional anisotropy (FA) in the splenium and inferior fronto-occipital fasciculus (IFOF). Controlling for Ud, GPF was associated with reduced FA in the genu and body of the corpus callosum. Conclusions: Decreasing WMI in the genu and body with increasing psychopathology across diagnoses suggests demyelinization in these areas and may underlie comorbidity and presence of symptoms that transcend psychopathological diagnoses. In contrast, trauma-related WMI reductions in the splenium and IFOF may account for heterogeneity within diagnostic categories as a function of childhood trauma. These findings support the importance of a dimensional approach in addition to traditional diagnostic classifications in clinical research and practice.

Can thwarted belongingness and perceived burdensomeness, risk factors for suicidal adolescents, be turned around by family group conferences? In this case study on Nick, a 17-year-old who undertook six suicide attempts, we (including Nick) share insights and learning opportunities on how family group conferences can be used. The thematic analysis suggests that family group conferences might be a promising intervention for suicidal adolescents. For Nick, the conference was a turning point in his life, correcting perceptions of being a burden, pushing back passiveness, and boosting connection with and support from the broad social network.

Objective: Oppositional defiant disorder (ODD) consists of irritable and oppositional behaviors, both of which are associated with different problems. However, it is unclear whether irritability and oppositionality enable classification of clinic-referred children and adolescents into mutually exclusive groups (e.g., high in oppositionality, low in irritability), and whether this classification is clinically meaningful. Method: As part of a clinical protocol, ODD behaviors were assessed at referral through a comprehensive diagnostic interview and questionnaire. Parent- and teacher-reported ODD of 2,185 clinic-referred 5- to 18-year-olds (36.9% females) were used in latent class analysis. Resulting ODD classes were compared, concurrently at referral, and, longitudinally at the end of the diagnostic and treatment process, on various clinically relevant measures that were completed by various informants, including mental health problems, global functioning, and Diagnostic and Statistical Manual of Mental Disorders ( DSM) classifications. Results: Three classes emerged with high, moderate, and low levels of both irritability and oppositionality. At referral, the high class experienced the highest levels of mental health problems and DSM classifications. Importantly, all ODD classes defined at intake were predictive of diagnostic and treatment outcomes months later. Notably, the high class had higher rates of clinician-based classifications of ODD and conduct disorder, and the lowest levels of pre- and posttreatment global functioning. Additionally, the low class exhibited higher rates of generalized anxiety disorder and fear disorders. Conclusions: Irritability and oppositionality co-occur in clinic-referred youths to such an extent that classification based on these behaviors does not add to clinical inference. Instead, findings suggest that the overall ODD severity at referral should be used as a guidance for treatment.

As hospital beds are scarce, and emergency admissions to a psychiatric ward are major life-events for children and adolescents, it is essential to have insight into the decision-making process that leads to them. To identify potentially modifiable factors, we, therefore, studied the contextual and clinical characteristics associated with the voluntary and compulsory emergency admission of minors. We used registry data (2008–2017) on 1194 outpatient emergencies involving children aged 6–18 who had been referred to the mobile psychiatric emergency service in two city areas in The Netherlands. Demographic and contextual factors were collected, as well as clinical characteristics including diagnoses, psychiatric history, Global Assessment of Functioning (GAF), and the Severity of Psychiatric Illness (SPI) scale. Logistic regression analyses were used to identify factors that predict voluntary or compulsory admission. Of 1194 consultations, 227 (19.0%) resulted in an admission, with 137 patients (11.5%) being admitted voluntarily and 90 (7.5%) compulsorily. Independently of legal status, the following characteristics were associated with admission: severity of psychiatric symptoms, consultation outside the patient’s home, and high levels of family disruption. Relative to voluntary admission, compulsory admission was associated with more severe psychiatric problems, higher suicide risk, and prior emergency compulsory admission. Two potentially modifiable factors were associated with psychiatric emergency admission: the place where patients were seen for consultation, and the presence of family problems. Psychiatric emergency admissions may be reduced if, whenever possible, minors are seen in their homes and if a system-oriented approach is used.

To overcome fragmentation in support for children and their families with multiple and enduring problems across life domains, professionals increasingly try to organize integrated care. However, it is unclear what facilitators and barriers professionals experience when providing this integrated care. Our systematic review, including 55 studies from a broad variety of settings in Youth Care, showed that integrated care on a professional level is a multi-component entity consisting of several facilitators and barriers. Findings were clustered in seven general themes: ‘Child’s environment’, ‘Preconditions’, ‘Care process’, ‘Expertise’, ‘Interprofessional collaboration’, ‘Information exchange’, and ‘Professional identity’. The identified facilitators and barriers were generally consistent across studies, indicating broad applicability across settings and professional disciplines. This review clearly shows that when Youth Care professionals address a broad spectrum of problems, a variety of facilitators and barriers should be considered.

We investigated the potential role of first-session therapeutic alliance ratings to serve as an early marker of treatment outcome in youth mental health and addiction treatment. The present study is among the first to incorporate both a youths’ and a therapists’ perspective of the therapeutic alliance in order to maximize predictive value of the alliance for treatment outcome. One hundred and twenty-seven adolescents participated in a multi-site prospective naturalistic clinical cohort study, with assessments at baseline and at 4 months post-baseline. Main outcome measure was favorable or unfavorable treatment outcome status at 4-month follow-up. Early therapeutic alliance had a medium and robust association with treatment outcome for youth’ (b = 1.29) and therapist’ (b = 1.12) perspectives and treatment setting. Based on the two alliance perspectives four subgroups were distinguished. Incorporating the alliance-ratings from both perspectives provided a stronger predictor of treatment outcome than using one perspective. Youth with a strong alliance according to both perspectives had an eightfold odds of favorable treatment outcome compared with youth with a weak alliance according to both perspectives. The association between therapeutic alliance and treatment outcome in youth mental health and addiction treatment may be substantially stronger than earlier assumed when both a youths’ and therapists’ perspective on alliance is considered.

The aim of this study in a high-risk adolescent sample with personality disorders receiving intensive mentalisation-based treatment (MBT), was first, to examine deviations in insecure attachment distribution of the normative pattern, and in borderline personality disorder and other personality disorders; second, to explore whether MBT alters attachment representations and whether these alterations are related to changes in psychological distress. A total of 60 adolescents were investigated pre-treatment for both categorical and continuous measures of the Adult Attachment Interview (AAI). Pre- and post-AAI (N = 33) data were compared with psychological distress measured by the Symptom Checklist-90. While the most disturbed category of insecure attachment, the “cannot classify“ category, was overrepresented (46.7%) at pre-treatment, no differences were observed by type of personality disorder. At post-treatment, 48.5% of the participants showed positive change in the attachment representation, and their psychological distress lowered significantly (p = .002). The whole sample demonstrated change towards increased secure attachment (z = −2.85, p = .004). Attachment insecurity was found in all adolescent personality disorders which MBT seemed to be able to alter. However, as we included no control group, we cannot conclude that changes are due to the treatment itself.

Exposure to childhood adverse events is associated with severe consequences for general health and structural and functional changes in the brain of its survivors. In order to unravel and in the end influence the pathway linking adversity and pathology, neuroimaging research is crucial. Up till now studies in minors are scarce and differ in type of adversity or methodology. Almost all studies report lower cortical thickness, but in a broad variety of regions. In this study we investigated cortical thickness measures and clinical data in a well circumscribed group of adolescents with PTSD related to childhood sexual abuse (CSA) (N = 21) and a healthy non-traumatised control group (N = 21). The ventromedial PFC (vmPFC), ACC, insula, and middle/superior temporal gyrus were chosen as ROI’s due to their respective roles in emotion and information processing. No significant effect of group was found for cortical thickness, surface area or volume in any of the ROIs. This is in line with the results of research in adult women with sexual abuse related PTSD, suggesting that this may be specific to this group, independent of age. Recent research points to differential biological and pathological consequences of different types of childhood adversity.

Reduced responsiveness to emotions is hypothesized to contribute to the development of conduct disorder (CD) in children and adolescents. Accordingly, blunted psychophysiological responses to emotions have been observed in boys with CD, but this has never been tested in girls. Therefore, this study compared psychophysiological responses to sadness in girls and boys with and without CD, and different clinical phenotypes of CD: with versus without limited prosocial emotions (LPE), and with versus without comorbid internalizing disorders (INT). Nine-hundred and 27 girls (427 CD, 500 controls) and 519 boys (266 CD, 253 controls) aged 9-18 years participated. Psychophysiological responses were measured while participants watched two validated sad film clips, specifically: heart rate (HR), respiratory sinus arrhythmia (RSA; indexing parasympathetic activity), preejection period (PEP; indexing sympathetic activity). Girls and boys with CD showed larger HR responses to sadness than controls. This effect was rendered nonsignificant, however, after controlling for covariates. We observed aberrant RSA responses to sadness in CD compared with controls. Similarly, we found a significant positive association between RSA responsivity and antisocial behavior when assessed dimensionally. The effects were very small, though. Results were similar for boys and girls. We found no evidence for emotional underresponsiveness in CD in the largest psychophysiological study to date in this field. More research is needed to explore whether this is specific to sadness or generalizes to other emotions. Furthermore, we recommend that studies on emotion processing in CD assess different physiological measures to help disentangle CD-related effects on sympathetic and parasympathetic activity.

Staff members in residential care for youth are frequently confronted with aggressive behaviour, which has adverse effects on their stress levels and work satisfaction. This paper describes a qualitative evaluation to find out how staff members benefit from Non-violent Resistance (NVR), a method to create an aggression mitigating residential climate. Staff members were positive about NVR and reported feeling more relaxed. Most valued aspects of this method were the focus on being a team, delayed response and giving up the illusion of control. However, training and the intention to use NVR isn't enough, high quality implementation and maintenance are crucial.

Objective: It has been hypothesised that clinically important age-related differences between adults with anxiety disorders exist; this study aims to elucidate these differences. Methods: We analysed data from 1950 outpatients diagnosed with DSM-IV-TR anxiety disorders treated at a Dutch hospital or affiliated mental healthcare centres. Three age-groups (young- (18–25; n = 435), mid- (26–40; n = 788) and older adult (41–65; n = 727)) were compared with regard to social demographic characteristics, diagnostic characteristics, anxiety symptom profile, general psychiatric symptom profile and generic health status, in addition, linear analyses were carried out with age as a continuous variable. Results: Average age was 36.48 years (SD 11.71), 62.8% were female. Significant associations with age emerged for gender, employment, education level, living situation, observed depression, agoraphobia (AP), social phobia, aches and pains, inner tension, sleep, interpersonal sensitivity, observed hostility, physical functioning, role limitations due to physical problems, vitality and bodily pain in categorical and continuous analyses. Self reported hostility was only significant in group-wise comparisons; role limitations due to emotional problems were only significant in linear analyses (all at p Conclusions: This study identified clinically relevant differences between younger and older adult outpatients with anxiety disorders. Clinicians should take these findings into account, as they may support treatment.

This qualitative study explored how adolescent boys with autism spectrum disorder experience their sexuality. Previous research has demonstrated that sexuality is a developmental task for boys with autism spectrum disorder, as it is for their peers. Case studies have suggested a relation between autism spectrum disorder and atypical sexual development; empirical studies on this subject, however, are scant and inconsistent. This study is based on interviews with eight boys, aged 16–20 years, with Asperger’s disorder or autistic disorder. Interpretative phenomenological analysis of the data revealed three major themes relating to (a) how they experience sexual feelings, think about sexuality and think about themselves as sexual beings; (b) how they perceive messages relating to sexuality in their surroundings; and (c) how they experience finding and having a partner and partnered sex. We believe that attention to these themes is needed in assessment, education and further research.

Early onset is regarded as an important characteristic of anxiety disorders, associated with higher severity. However, previous findings diverge, as definitions of early onset vary and are often unsubstantiated. We objectively defined early onset in social phobia, panic disorder, agoraphobia, and generalised anxiety disorder, using cluster analysis with data gathered in the general population. Resulting cut-off ages for early onset were ≤22 (social phobia), ≤31 (panic disorder), ≤21 (agoraphobia), and ≤27 (generalised anxiety disorder). Comparison of psychiatric comorbidity and general wellbeing between subjects with early and late onset in the general population and an outpatient cohort, demonstrated that among outpatients anxiety comorbidity was more common in early onset agoraphobia, but also that anxiety- as well as mood comorbidity were more common in late onset social phobia. A major limitation was the retrospective assessment of onset. Our results encourage future studies into correlates of early onset of psychiatric disorders.

PURPOSE: Besides reducing recidivism, juvenile justice institutions aim to rehabilitate juvenile delinquents, in order for them to reintegrate in society. As such, improving quality of life (QoL), especially post detention, is an important treatment goal. However, research is primarily focused on recidivism as an outcome measure for juvenile detention. The aim of the current study is therefore to describe and predict QoL of detained young offenders up to 1 year after an initial assessment, and to examine whether QoL differs between youth who are still detained versus released.METHODS: A sample of 186 juveniles admitted to juvenile justice institutions in the Netherlands was assessed within the institution (initial assessment/T0), using psychosocial and neurobiological factors as predictors (self-control, treatment motivation, trauma, mental health problems, respiratory sinus arrhythmia). QoL (MANSA), as well as substance use (alcohol, cannabis) and daily activities (education, work) were assessed at first, second, and third follow-up (respectively 2.5 months, 4.5 months, and 12 months after T0).RESULTS: QoL increased from first to third follow-up, and was higher for individuals who were no longer detained. The model that best predicted higher QoL upon follow-up consisted of lower trauma and stronger parasympathetic nervous system reactivity. The effects of the predictors did not differ between the various follow-ups, nor between individuals who were or were not detained.CONCLUSION: Methods incorporating trauma-sensitive focus and relaxation techniques in treatment protocols in juvenile justice institutions may be of added value in improving the general functioning of these individuals.

Loss and abuse in children can lead to unresolved-disorganized (UD) attachment. How this condition relates to brain structure and functional connectivity (FC) is unknown. We therefore aimed to investigate gray matter volume (GMV) and resting state functional connectivity (RSFC) correlates of UD attachment in adolescents. Based on previous neuroimaging studies of trauma effects, we hypothesized that the structure of the amygdala and hippocampus and the FC of the latter would be linked to UD attachment. Anatomical and RSFC data were collected from a mixed group of adolescents (N = 74) with symptoms of posttraumatic stress disorder (PTSD) related to childhood sexual abuse (CSA), anxiety/depressive symptoms, and without psychiatric disorder as part of the Emotional Pathways' Imaging Study in Clinical Adolescents (EPISCA). Bilateral volumes of the amygdala and hippocampus were measured using the FMRIB Software Library, and RSFC of the hippocampus was assessed using seed-based correlation. UD attachment was measured using the Adult Attachment Interview. Hierarchical regression and correlation were used to assess the associations between UD status (continuous and categorical), brain structure, and FC, adjusting for a general psychopathology factor, puberty stage, gender, age, and IQ. UD attachment was associated with a smaller left hippocampal volume, RSpanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) El apego desorganizado no resuelto asociado con un menor hipocampo y un incremento de la conectividad funcional más allá de la psicopatología APEGO, HIPOCAMPO Y CONECTIVIDAD FUNCIONAL.

Not only are childhood onset offenders at high risk of becoming serious persistent offenders, they are also at high risk of becoming victimized themselves. Furthermore, studies in the general population suggest that a combined perpetrator–victim group can be distinguished from a perpetrator-only and a victim-only group on individual and family risk factors. The current study investigated the co-occurrence of offending and victimization among first-time arrestees and the 2-year predictive value of previously found clusters of dynamic risk factors of offending. Childhood first-time arrestees ( N = 308; Mage= 10.3, SD = 1.45) were clustered into three groups based on dynamic risk factors of offending in the individual, peer, school, and family domains: a pervasive high, an externalizing intermediate, and a low problem group. Police records and self-report data on re-offending and victimization of these children were collected over a 2-year follow-up period. Compared with the low problem group, the prevalence of re-offending was higher in both the externalizing intermediate group and the pervasive high group. The pervasive high group was most likely to display co-occurring future antisocial behavior and victimization. These findings emphasize that attention should be paid to victimization in addition to future antisocial behavior, especially if additional internalizing and family problems are present. Furthermore, the differences in re-offending and victimization between subgroups of childhood onset offenders stress the need for specific interventions tailored to the risk profile of a child.

Background: Reflecting evidence on Callous-Unemotional (CU) traits (e.g., lack of empathy and guilt, shallow affect), the DSM-5 added a categorical CU-based specifier for Conduct Disorder (CD), labeled 'with Limited Prosocial Emotions' (LPE). Theory and prior work suggest that CD youths with and without LPE will likely differ in neural processing of negative socioemotional content. This proposition, however, is mainly derived from studies employing related, yet distinct, operationalizations of CU traits (e.g., dimensional measure/median split/top quartile), thus precluding direct examination of LPE-specific neurocognitive deficits.Methods: Employing a DSM-5 informed LPE proxy, neural processing of recognizing and resonating negative socioemotional content (angry and fearful faces) was therefore examined here among CD offenders with LPE (CD/LPE+; N = 19), relative to CD offenders without LPE (CD/LPE-; N = 31) and healthy controls (HC; N = 31).Results: Relative to HC and CD/LPEyouths and according to a linearly increasing trend (CD/LPE- < HC < CD/LPE+), CD/LPE+ youths exhibited hyperactivity within dorsolateral, dorsomedial, and ventromedial prefrontal regions during both emotion recognition and resonance. During emotion resonance, CD/LPE+ youths additionally showed increased activity within the posterior cingulate and precuneal cortices in comparison to HC and CD/LPE- youths, which again followed a linearly increasing trend (CD/LPE- < HC < CD/LPE+). These effects moreover seemed specific to the LPE specifier, when compared to a commonly employed method for CU-based grouping in CD (i.e., median split on CU scores).Conclusions: These data cautiously suggest that CD/LPE+ youths may exhibit an over-reliance on cortical neurocognitive systems when explicitly processing negative socioemotional information, which could have adverse downstream effects on relevant socioemotional functions. The findings thus seem to provide novel, yet preliminary, clues on the neurocognitive profile of CD/LPE+, and additionally highlight the potential scientific utility of the LPE specifier.

Juveniles who have committed a sexual offense (JSOs) are thought to have abnormal sexual development, as well as increased ASD symptoms. In the current study, sexual development and behavior, as well as stability of ASD-like symptoms were assessed in a sample of 44 male JSOs (mean age 24.7 ± 1.5 years) 8 years after their sexual offence. JSOs exhibited less knowledge of sexuality, less positive attitudes towards pornography and more often reported having been a victim of verbal sexual intimidation than a matched normal population sample. ASD symptoms were relatively stable over the 8 years follow-up, indicating that social difficulties in JSOs may be part of life-long autistic-like traits. However, ASD symptoms were not related to alterations in sexual development or behavior.

Research suggests that individuals with conduct disorder (CD) are marked by social impairments, such as difficulties in processing the affective reactions of others. Little is known, though, about how they make decisions during social interactions in response to emotional expressions of others. In this study, we therefore investigated the neural mechanisms underlying fairness decisions in response to communicated emotions of others in aggressive, criminal justice-involved boys with CD (N = 32) compared with typically developing (TD) boys (N = 33), aged 15-19 years. Participants received written emotional responses (angry, disappointed or happy) from peers in response to a previous offer and then had to make fairness decisions in a version of the Dictator Game. Behavioral results showed that CD boys did not make differential fairness decisions in response to the emotions, whereas the TD boys did show a differentiation and also responded more unfair to happy reactions than the CD boys. Neuroimaging results revealed that when receiving happy vs disappointed and angry reactions, the CD boys showed less activation than the TD boys in the temporoparietal junction and supramarginal gyrus, regions involved in perspective taking and attention. These results suggest that boys with CD have difficulties with processing explicit emotional cues from others on behavioral and neural levels.

BACKGROUND: The developmental trajectory of psychopathy seemingly begins early in life and includes the presence of callous-unemotional (CU) traits (e.g., perturbed socioaffective reactivity and empathy, callousness) in youths with conduct disorder (CD). Whereas oxytocin receptor gene methylation (OXTRMeth) and its downstream neuromodulatory effects are deemed relevant to CU traits, nothing is known of how OXTRMeth interacts with CU traits to impact socioaffective brain systems in youngsters with CD.METHODS: Hence, we uniquely probed OXTRMeth × CU trait interactions on corticolimbic activity and amygdala subregional connections during recognition and resonance of distressing socioaffective stimuli (angry and fearful faces), in juvenile offenders with CD (n = 39) versus matched healthy control youths (n = 27).RESULTS: Relative to healthy control youths, elevated OXTRMeth and CU levels in youths with CD essentially interacted to predict frontoparietal hyperactivity and amygdalo-frontoparietal disconnection during task performance. Specifically, increasing OXTRMeth and CU levels in youths with CD interactively predicted midcingulate hyperactivity during both emotion conditions, with insular, temporoparietal, and precuneal hyperactivity additionally emerging during emotion recognition. Interactions between high OXTRMeth and CU levels in youths with CD additionally predicted centromedial amygdala decoupling from ventromedial/orbitofrontal regions during emotion recognition, along with basolateral amygdala decoupling from precuneal and temporoparietal cortices during emotion resonance.CONCLUSIONS: These results uniquely suggest that interactions between OXTRMeth and CU traits in youths with CD may affect brain systems critical to decoding and integrating socioaffective information. Developmental models of CU traits and psychopathy could thus possibly advance by further examining OXTR epigenetic effects, which may hold promise for indicated prevention and personalized treatment by targeting oxytocinergic function.

Childhood aggression and its resulting consequences inflict a huge burden on affected children, their relatives, teachers, peers and society as a whole. Aggression during childhood rarely occurs in isolation and is correlated with other symptoms of childhood psychopathology. In this paper, we aim to describe and improve the understanding of the co-occurrence of aggression with other forms of childhood psychopathology. We focus on the co-occurrence of aggression and other childhood behavioural and emotional problems, including other externalising problems, attention problems and anxiety-depression. The data were brought together within the EU-ACTION (Aggression in Children: unravelling gene-environment interplay to inform Treatment and InterventiON strategies) project. We analysed the co-occurrence of aggression and other childhood behavioural and emotional problems as a function of the child's age (ages 3 through 16years), gender, the person rating the behaviour (father, mother or self) and assessment instrument. The data came from six large population-based European cohort studies from the Netherlands (2x), the UK, Finland and Sweden (2x). Multiple assessment instruments, including the Child Behaviour Checklist (CBCL), the Strengths and Difficulties Questionnaire (SDQ) and Multidimensional Peer Nomination Inventory (MPNI), were used. There was a good representation of boys and girls in each age category, with data for 30,523 3- to 4-year-olds (49.5% boys), 20,958 5- to 6-year-olds (49.6% boys), 18,291 7- to 8-year-olds (49.0% boys), 27,218 9- to 10-year-olds (49.4% boys), 18,543 12- to 13-year-olds (48.9% boys) and 10,088 15- to 16-year-olds (46.6% boys). We replicated the well-established gender differences in average aggression scores at most ages for parental ratings. The gender differences decreased with age and were not present for self-reports. Aggression co-occurred with the majority of other behavioural and social problems, from both externalising and internalising domains. At each age, the co-occurrence was particularly prevalent for aggression and oppositional and ADHD-related problems, with correlations of around 0.5 in general. Aggression also showed substantial associations with anxiety-depression and other internalizing symptoms (correlations around 0.4). Co-occurrence for self-reported problems was somewhat higher than for parental reports, but we found neither rater differences, nor differences across assessment instruments in co-occurrence patterns. There were large similarities in co-occurrence patterns across the different European countries. Finally, co-occurrence was generally stable across age and sex, and if any change was observed, it indicated stronger correlations when children grew older. We present an online tool to visualise these associations as a function of rater, gender, instrument and cohort. In addition, we present a description of the full EU-ACTION projects, its first results and the future perspectives.

Adverse childhood experiences (ACE) substantially increase the risk of later psychiatric and somatic pathology. While neurobiological factors are likely to play a mediating role, specific insights are lacking. The scarce neuroimaging studies in traumatised pediatric populations have provided inconsistent results, potentially due to the inclusion of different types of trauma. To further improve our understanding of the neurobiology of pediatric psychotrauma, this study seeks to investigate abnormalities in grey matter volume (GMV) in a homogeneous group of adolescents with posttraumatic stress disorder (PTSD) due to childhood sexual abuse (CSA) and the relationship between GMV and symptom severity. We performed a voxel based morphometry (VBM) analysis in 21 adolescents with CSA-related PTSD and 25 matched non-traumatised, non- clinical adolescents. Hippocampus, amygdala, anterior cingulate cortex (ACC), medial PFC (mPFC) and superior temporal gyrus (STG) were chosen as regions of interest (ROIs). Trauma symptomatology was measured with the Trauma Symptom Checklist for Children (TSCC) and dissociation symptoms with the Adolescent Dissociative Experiences Scale (A-DES). The ROI analysis showed that the CSA-related PTSD group had significant smaller volumes of the dorsal ACC as compared to healthy controls. However, no correlations were found between GMV and scores on the TSCC and A-DES. The smaller ACC volume is partly in line with previous studies in traumatised youth and is a consistent finding in traumatised adults. Taken together our results suggest that the dorsal ACC is implicated in the neurobiological sequelae of CSA, potentially associated with an altered evaluative processing of emotion, but not directly with PTSD severity.

Little is known about how emotions expressed by others influence social decisions and associated brain responses in autism spectrum disorders (ASD). We investigated the neural mechanisms underlying fairness decisions in response to explicitly expressed emotions of others in boys with ASD and typically developing (TD) boys. Participants with ASD adjusted their allocation behavior in response to the emotions but reacted less unfair than TD controls in response to happiness. We also found reduced brain responses in the precental gyrus in the ASD versus TD group when receiving happy versus angry reactions and autistic traits were positively associated with activity in the postcentral gyrus. These results provide indications for a role of precentral and postcentral gyrus in social-affective difficulties in ASD.

Background The developmental trajectory of psychopathy seemingly begins early in life and includes the presence of callous-unemotional (CU) traits (e.g., deficient emotional reactivity, callousness) in conduct-disordered (CD) youth. Though subregion-specific anomalies in amygdala function have been suggested in CU pathophysiology among antisocial populations, system-level studies of CU traits have typically examined the amygdala as a unitary structure. Hence, nothing is yet known of how amygdala subregional network function may contribute to callous-unemotionality in severely antisocial people. Methods We addressed this important issue by uniquely examining the intrinsic functional connectivity of basolateral amygdala (BLA) and centromedial amygdala (CMA) networks across three matched groups of juveniles: CD offenders with CU traits (CD/CU+; n = 25), CD offenders without CU traits (CD/CU−; n = 25), and healthy control subjects ( n = 24). We additionally examined whether perturbed amygdala subregional connectivity coincides with altered volume and shape of the amygdaloid complex. Results Relative to CD/CU− and healthy control youths, CD/CU+ youths showed abnormally increased BLA connectivity with a cluster that included both dorsal and ventral portions of the anterior cingulate and medial prefrontal cortices, along with posterior cingulate, sensory associative, and striatal regions. In contrast, compared with CD/CU− and healthy control youths, CD/CU+ youths showed diminished CMA connectivity with ventromedial/orbitofrontal regions. Critically, these connectivity changes coincided with local hypotrophy of BLA and CMA subregions (without being statistically correlated) and were associated to more severe CU symptoms. Conclusions These findings provide unique insights into a putative mechanism for perturbed attention-emotion interactions, which could bias salience processing and associative learning in youth with CD/CU+.

Background: Multidimensional family therapy (MDFT) is a well-established treatment for adolescents showing both substance abuse and/or antisocial behavior. Method: The effectiveness of MDFT in reducing adolescents’ substance abuse, delinquency, externalizing and internalizing psychopathology, and family malfunctioning was examined by means of a (three-level) meta-analysis, summarizing 61 effect sizes from 19 manuscripts (N = 1,488 participants). Results: Compared with other therapies, the overall effect size of MDFT was significant, albeit small in magnitude (d = 0.24, p

Objective Although detained adolescent females show high rates of severe aggression, we know little about the long-term impact of this risk-behavior. Furthermore, qualitative differences in aggression between males and females argue for gender specific research. In contrast to males, females display aggressive acts more often towards themselves (inward aggression; self harm behavior) than towards others (outward aggression). Therefore, this prospective study investigated the prevalence and predictive validity of different types of aggression in detained adolescent females. Method Participants were 139 adolescent females (mean age 20.1) assessed at start of detention and 5 years later. Both inward and outward aggression subtypes were assessed twice using standardized instruments. Mutual relations over time were analyzed by means of structural equation modeling. Results High levels of all types of aggression were found repeatedly, suggesting substantial persistence over time. While inward aggression predicted both inward and outward aggression at follow-up, outward aggression was related to outward aggression only. Furthermore, the covert form of outward aggression only, and not the overt subtype, predicted outward aggression 5 years later. Conclusions This study suggests that aggression in detained adolescent females does not fade away, and should thus be given substantial clinical attention. In assessment, focus should also be on inward and covert subtypes. Further research should explore the necessity of developing gender-specific diagnostic instruments, treatment modules and risk assessment tools. When replicated, our findings may also bear implications for the classification of behavior disorders in adolescent females.

Mounting evidence indicates that emotional maltreatment is at least as harmful as physical and sexual abuse. Notwithstanding their high occurrence among detained adolescents, the link between emotional maltreatment and mental health problems in these youths is not well researched. This study, therefore, was designed to examine the unique link between emotional maltreatment and mental health problems, with particular attention to gender differences. Well validated self-report measures of maltreatment experiences (Childhood Trauma Questionnaire) and mental health problems (Youth Self Report) were completed by 341 detained adolescents (156 boys, 185 girls) aged 12 to 18 years. As expected, girls reported higher levels of maltreatment experiences and internalizing and externalizing mental health problems than boys. Blockwise multiple linear regression analyses indicated that in both genders emotional abuse was uniquely and positively associated with internalizing and externalizing mental health problems, over and above the influence of other types of maltreatment. Furthermore, sexual abuse was uniquely related with internalizing problems in girls only, whereas only in boys this type of abuse was uniquely related with externalizing problems. Detained adolescents who have been the victim of emotional abuse in combination with another type of maltreatment may be the worst subgroup in terms of mental health problems. Therefore, emotional maltreatment experiences in adolescents who offend should receive more research and clinical attention.

A large proportion (28% up to 75%) of the treatments in youth mental health care results in premature termination (dropout). It is important to gain knowledge of the determinants of dropout because it can have very severe consequences. The aim of our meta-analytic review was to provide an overview of findings from empirical studies on this subject. We structured the often contradicting results from two perspectives. First, we compared studies with efficacy and effectiveness designs. Second, we compared studies which used a dropout definition based on the opinion of therapists, with those that took the number of predetermined completed sessions as a criterion. Third, we studied three groups of predictors, i.e., pre-treatment child variables, pre-treatment family or parent variables, and treatment and therapist variables or treatment participation barriers.The meta-analytic review showed that dropout percentages were strongly influenced by study design: Percentages were lower in efficacy than in effectiveness studies. Within effectiveness studies, the dropout percentages were lower when the therapist's opinion was used rather than when the number of sessions was used as a criterion. In efficacy studies on the contrary, the dropout percentages were similar for studies using the first or the second criterion. With respect to dropout predictors, results were less clear. Some of the dropout predictors were influenced by study design or dropout definition, but for most predictors this influence could not be analyzed because they were not studied in all groups of studies or because the effect sizes were small or non-significant. Treatment and therapist variables or experienced treatment participation barriers were overall stronger dropout predictors than the pre-treatment child variables and pre-treatment family or parent variables, although some strong predictive pre-treatment variables emerged as well.

Unlike adolescents with adolescent-onset (AO) disruptive behavior, adolescents with early-onset (EO) disruptive behavior may not benefit from treatment.Using Symptom Checklist (SCL-90-R) ratings at admission and discharge of adolescent inpatients with EO (n = 85) and AO (n = 60) disruptive behavior treatment outcome was determined by (a) a change in mean scores and (b) the Reliable Change Index. For a subgroup, ratings on the Satisfaction Questionnaire Residential Youth Care for Parents (n = 83) were used to verify the treatment outcome.Inpatients with EO disruptive behavior had a higher risk of dropout (44.4%) from treatment than the AO group (24.7%). Among the treatment completers, both onset groups reported improvements on the SCL-90-R, with 26.9% recovering and 31.7% improving. Inpatients who reported improvement were mostly rated as improved by their parents (r = .33).As EO inpatients are more likely to drop out, interventions should aim at motivating youngsters to continue treatment, particularly given the poor outcome in this group. Treatment may benefit both groups because those EO youths who stayed in treatment improved to the same extent as AO inpatients.

Detained girls bear high levels of criminal behavior and mental health problems that are likely to persist into young adulthood. Research with these girls began primarily from a risk management perspective, whereas a strength-based empowering perspective may increase knowledge that could improve rehabilitation. This study examines detained girls' quality of life (QoL) in relation to future mental health problems and offending, thereby testing the strength-based good lives model of offender rehabilitation (GLM). At baseline, 95 girls (Mage = 16.25) completed the World Health Organization QoL instrument to assess their QoL prior to detention in the domains of physical health, psychological health, social relationships, and environment. Six months after discharge, mental health problems and offending were assessed by self-report measures. Structural equation models were conducted to test GLM's proposed (in)direct pathways from QoL (via mental health problems) toward offending. Although we could not find support for GLM's direct negative pathway from QoL to offending, our findings did provide support for GLM's indirect negative pathway via mental health problems to future offending. In addition, we found a direct positive pathway from detained girls' satisfaction with their social relationships to offending after discharge. The current findings support the potential relevance of addressing detained girls' QoL, pursuing the development of new skills, and supporting them to build constructive social contacts. Our findings, however, also show that clinicians should not only focus on strengths but that detecting and modifying mental health problems in this vulnerable group is also warranted.

Posttraumatic stress disorder (PTSD) is a prevalent, debilitating, and difficult to treat psychiatric disorder. Very little is known of how PTSD affects neuroplasticity in the developing adolescent brain. Whereas multiple lines of research implicate amygdala-centered network dysfunction in the pathophysiology of adult PTSD, no study has yet examined the functional architecture of amygdala subregional networks in adolescent PTSD. Using intrinsic functional connectivity analysis, we investigated functional connectivity of the basolateral (BLA) and centromedial (CMA) amygdala in 19 sexually abused adolescents with PTSD relative to 23 matched controls. Additionally, we examined whether altered amygdala subregional connectivity coincides with abnormal grey matter volume of the amygdaloid complex. Our analysis revealed abnormal amygdalar connectivity and morphology in adolescent PTSD patients. More specifically, PTSD patients showed diminished right BLA connectivity with a cluster including dorsal and ventral portions of the anterior cingulate and medial prefrontal cortices (p

Over the past 20 years there has been a marked increase in research relating to forensic child and adolescent psychiatry.To review briefly and reflect on this research.First of all, we describe the characteristics of forensic psychiatry and consider the consequences of this type of psychiatry for research in forensic settings. Secondly, we highlight several lines of research; these range from neurobiology to the prevalence of psychiatric disorders in persons who have committed specific types of offences.A majority of young people who have been in contact with the law appeared to have a psychiatric disorder, especially behavioural disorders, ADHD and substance abuse. However, also anxiety and depressive disorders were found in 10-20% of all delinquent young people. Particularly the existence of more than one disorder showed a connection between the nature and the severity of the delinquent behaviour and the disfunctioning of the adolescent. Current research focuses on stress and HPA axis of young people in relation to proactive and reactive aggression.In the past decades research in forensic child and adolescent psychiatry has taken an enormous flight. One of the challenges for the future will be translating the results of the research into practice.

In DSM 5, conduct disorder (CD) has been expanded with a new specifier ‘with Limited Prosocial Emotions’ (LPE) in addition to the age-of-onset (AoO) subtyping, and is thought to identify a severe antisocial subgroup of CD. However, research in clinical practice has been scarce. Therefore, the current study will examine differences in clinical symptoms between subtypes of CD, based on both subtyping schemes. Subsequently, it will investigate whether the LPE specifier explains unique variance in aggression, added to the AoO subtyping. A sample of 145 adolescents with CD (51 % male, mean age 15.0) from a closed treatment institution participated in this study. CD diagnoses and AoO subtype were assessed using a structured diagnostic interview. The LPE specifier was assessed using the callous–unemotional dimension of the Youth Psychopathy Traits Inventory (YPI). Self-reported proactive and reactive aggression, rule-breaking behavior and internalizing problems within the subtypes were compared. Youth with childhood-onset CD and LPE showed significantly more aggression than adolescent-onset CD without LPE (proactive aggression: F = 3.1, p

Highlights • A study investigating habituation patterns in the amygdala. • Compares adolescents with internalizing disorders and adolescents with CSA-related PTSD. • Initial heightened response and fast habituation in amygdala for the PTSD group. • No habituation of amygdala response in the internalizing group. • Possible difference in underlying neurobiological mechanisms for emotional face processing., Adolescents with internalizing disorders and adolescents with childhood sexual abuse related post-traumatic stress disorder (CSA-related PTSD) show a large overlap in symptomatology. In addition, brain research indicated hyper-responsiveness and sustained activation instead of habituation of amygdala activation to emotional faces in both groups. Little is known, however, about whether the same patterns of amygdala habituation are present in these two groups. The current study examined habituation patterns of amygdala activity to emotional faces (fearful, happy and neutral) in adolescents with a DSM-IV depressive and/or anxiety disorder (N = 25), adolescents with CSA-related PTSD (N = 19) and healthy controls (N = 26). Behaviourally, the adolescents from the internalizing and CSA-related PTSD group reported more anxiety to fearful and neutral faces than adolescents from the control group and adolescents from the CSA-related PTSD group reacted slower compared to the internalizing group. At the whole brain level, there was a significant interaction between time and group within the left amygdala. Follow-up ROI analysis showed elevated initial activity in the amygdala and rapid habituation in the CSA-related PTSD group compared to the internalizing group. These findings suggest that habituation patterns of amygdala activation provide additional information on problems with emotional face processing. Furthermore, the results suggest there are differences in the underlying neurobiological mechanisms related to emotional face processing for adolescents with internalizing disorders and adolescents with CSA-related PTSD. Possibly CSA-related PTSD is characterized by a stronger primary emotional response driven by the amygdala.

Psychopathic traits and a history of maltreatment are well-known risk factors for mental health problems and aggression. A better insight in the impact of such risk factors on juvenile delinquents is likely to help tailoring treatment. Therefore, this study aimed to examine mental health problems and aggression in detained delinquent youths with various levels of psychopathic traits and maltreatment. Standardized questionnaires were used to assign 439 detained male adolescents (N = 439; from 13 to 18 years of age) to one of six mutually exclusive groups: adolescents with (1) low psychopathic traits without maltreatment; (2) low psychopathic traits and one type of maltreatment; (3) low psychopathic traits and multiple types of maltreatment; (4) high psychopathic traits without maltreatment; (5) high psychopathic traits and one type of maltreatment and finally (6) high psychopathic traits and multiple types of maltreatment. Next, groups were compared on mental' health problems, mental disorders and reactive and proactive aggression. Findings indicated that compared to the low psychopathic traits groups, high psychopathic traits groups had markedly higher levels of externalizing mental health problems (such as attention deficit/hyperactivity, substance abuse, rule-breaking), proactive and reactive aggression, but not of internalizing mental health problems (anxiety and depression). Mental health problems in boys with a low level of psychopathic traits increased with the number of types of maltreatment in their history. In boys with a high level of psychopathic traits, group differences did not reach significance. Levels of proactive and reactive aggression increased with the number of types of maltreatment in boys with low levels of psychopathic traits, but not in those with high psychopathic traits. Thus, in detained adolescents both psychopathic traits and the number of maltreatment types are related to the severity of mental health problems and types of aggression. When used in routine screening procedures, these risk factors may thus improve identification and support targeted treatment-allocation of detained adolescents with serious clinical problems.

ObjectiveParents are considered to be crucial informants in child psychiatry, particularly for disorders in which age of onset is included in the diagnostic criteria. In detained adolescents, however, parents all too often are difficult to reach or reluctant to cooperate. The clinical relevance of gathering parental information in this context should therefore be demonstrated. This study examines if parent reports of attention-deficit-hyperactivity disorder (ADHD) and age of onset subtypes of conduct disorder (CD) predict official criminal recidivism.MethodParticipants were 110 detained male adolescents from all three Youth Detention Centers in Flanders. Between January 2005 and February 2007, both youth and a parent were interviewed with the Diagnostic Interview Schedule for Children Version IV. Two to 4years later, information on criminal recidivism was retrieved.ResultsYouth self-reported ADHD and CD (subtypes) were not related with recidivism. Parent-reported ADHD, CD and childhood-onset CD predicted serious property recidivism, while parent-reported adolescent-onset CD predicted future violent arrests. In reverse, childhood-onset CD as reported by parents was negatively associated with violent recidivism.ConclusionObtaining parental diagnostic information in delinquent adolescents is crucial for predicting recidivism. This finding emphasizes the need of including parents when studying mental disorder in detained adolescents.

The main objectives were to evaluate efficacy and acceptability of a developmentally sensitive cognitive behavioral therapy for anxiety-based school refusal in adolescence. Twenty school-refusing adolescents meeting DSM-IV anxiety disorder criteria participated in a non-randomized trial, together with parents and school staff. Outcome was assessed at post-treatment and 2-month follow-up. Treated adolescents showed significant and maintained improvements across primary outcome variables (school attendance; school-related fear; anxiety), with medium to large effect sizes. Half of the adolescents were free of any anxiety disorder at follow-up. Additional improvements were observed across secondary outcome variables (depression; overall functioning; adolescent and parent self-efficacy). The treatment was rated as acceptable by adolescents, parents, and school staff, which may help explain the very low attrition rate. Social anxiety disorder was the most common disorder among adolescents still meeting anxiety disorder criteria at follow-up. Treatment modifications to improve efficacy for school-refusing adolescents presenting with social anxiety disorder are suggested.

The aim of this study was to investigate group sex offenses with regard to the role of leaders versus followers and to compare both groups on levels of psychopathology, intelligence, and psychosocial and offense-related characteristics. Eighty-nine adolescent group sex offenders (mean age = 14.9, SD = 1.4) referred by the police to the Dutch child protection agency were examined. Psychopathology, intelligence, and psychosocial and offense-related characteristics were assessed by means of standardized instruments, and criminal careers of the participants were ascertained from official judicial records. Although leaders and followers were similar on many characteristics, some remarkable differences were found. During their sexual acts, followers reported using excessive force more frequently than leaders. Furthermore, leaders reported more emotional problems, whereas followers were characterized by higher levels of problems in the social relational domain. As the findings indicate that juvenile group sex offenders constitute a group with specific mental health needs, diagnostic investigation is important to recognize risk factors and (treatable) problems. The absence of some expected differences between leaders and followers could be due to the method of classification or because group offending constitutes a dynamic process without clearly defined roles for individuals.

Objective: To provide a best estimate of the prevalence of psychiatric disorders among detained male adolescents, with particular emphasis on impairment, multi-informant assessment, and race or ethnicity. Method: Computer-assisted searches were executed to identify relevant studies. Results: Fifteen studies using adolescents as informants met inclusion criteria ( n = 3401), of which only 2 reported within a subsample on parent-derived diagnoses. The mean prevalence of any disorder was 69.9% (95% CI 69.5% to 70.3%); with conduct disorder occurring most frequently (46.4%, 95% CI 45.6% to 47.3%), followed by substance use disorder (45.1%, 95% CI 44.6% to 45.5%), oppositional defiant disorder (19.8%, 95% CI 19.2% to 20.3%), and attention-deficit hyperactivity disorder (13.5%, 95% CI 13.2% to 13.9%). Although lower, rates for internalizing disorders were still substantial, with any anxiety disorder found in 15.9% (95% CI 15.6% to 16.1%), major depression in 12.0% (95% CI 11.7% to 12.2%), and posttraumatic stress disorder in 9.6% (95% CI 9.2% to 10.0%). Three studies reported on psychotic disorders, finding low rates (1.35%, 95% CI 1.32% to 1.39%). Estimates of prevalence were only marginally different when impairment was not required, while consistency between adolescents and parents was poor. Findings on the relations between race or ethnicity were too scarce and inconsistent to interpret. Conclusion: Detained male adolescents bear substantial mental health needs, emphasizing the need to organize effective mental health services for this troubled group. However, our knowledge on mental disorders in detained youth should be enhanced, in particular regarding the reliability of adolescents, compared with parent report, and whether clinically relevant differences exist by race or ethnicity.

OBJECTIVE To investigate autism spectrum disorder (ASD) symptoms in juvenile suspects of sex offenses. METHOD A group of 175 juvenile suspected sex offenders (all males, mean +/- SD age = 14.9 +/- 1.4 years) was compared with a matched healthy control group (N = 500, mean +/- SD age = 14.0 +/- 1.4 years) and a group of children with DSM-IV-diagnosed ASD (N = 114, mean +/- SD age = 14.2 +/- 1.9 years) with respect to autistic symptoms as measured by means of a standardized questionnaire, the Children's Social Behavior Questionnaire. Furthermore, specific subgroups of sexual offenders, i.e., child molesters, solo peer offenders, and group offenders, were compared with regard to levels of ASD symptoms. The study was conducted from May 2003 to December 2006. RESULTS Significantly higher levels of ASD symptoms were found in juvenile sex offenders than in healthy controls, while levels were lower than in the ASD group (F = 148.259, p < .05). Solo peer offenders and child molesters scored higher on several subscales as well as on core autistic symptoms than group offenders (F = 5.127, p < .05). CONCLUSIONS Levels of ASD symptoms are higher in juvenile suspects of sex offenses as compared to the healthy population, which argues for considering specific diagnostic assessment in this population, especially in solo offenders and child molesters.

The aim of the study was to investigate a group of detained females with regard to aggression and psychopathology and to examine the relationship between the two conditions. For this purpose, a representative sample of 216 detained adolescent females aged 12-18 (mean 15.5) was studied with a standard set of self-report instruments, while a subgroup of 73 parents was interviewed by telephone on the participants' externalizing psychopathology. Based on aggression items derived from the Conduct Disorder section of the Kiddie-SADS, the following three aggression subgroups were identified: (1) non-aggressive (NA; 41%), (2) mildly aggressive (MA; 39%), and (3) severely aggressive (SA; 20%). In addition to high levels of psychopathology for the group as a whole, differences were found between aggression groups, with the NA group demonstrating the lowest levels, the MA group intermediate levels, and the SA group the highest levels. These differences were most pronounced for externalizing psychopathology, and were also found for post-traumatic stress symptomatology (PTSS) and suicidality. The clinical implications of these findings should be investigated in the future, but may well relate to issues of diagnostic identification and administration of adequate and targeted treatment, especially with regard to PTSS and suicidality. Since the current study was cross-sectional, the predictive effect of the investigated relationships should be the focus of further study.

There is some debate about whether or not sex offenders are similar to non-sex offenders with regard to family background (parental characteristics), personality, and psychopathology. The central aim of this study focused on the comparison of juvenile sex offenders and non-sex offenders. The sample consisted of incarcerated juvenile male sex (n = 30) and non-sex (n = 368) offenders. It appeared that sex offenders resembled non-sex offenders with respect to most of the offender and parental characteristics. Results demonstrated some differences between both groups, while the majority of characteristics were similar. Limitations of the study are discussed, especially the low number of sex offenders, followed by suggestions for further research.

Patterns of low hypothalamus-pituitary-adrenal (HPA) activity have been observed in antisocial groups. As conflicting results have been reported in children and adolescents, the aim of this study was to further investigate HPA activity in antisocial behavior by studying the relationship between the diurnal cortisol cycle, as well as the cortisol awakening response (CAR), and antisocial behavior in male adolescents. The diurnal cortisol cycle and the CAR during the first hour after awakening were compared between 12- to 14-year-old boys who attended a delinquency diversion program (DP), with and without a disruptive behavior disorder (DBD) (respectively DP+; n=24 and DP-; n=65), and matched normal controls (NC; n=32). The DP+ group, but not the DP- group, showed a significantly slower decrease of cortisol during the diurnal cycle than the NC group. Furthermore, the DP+ group had significantly lower cortisol levels in the first hour after awakening as compared with the NC group. The results indicate altered HPA activity in delinquent boys with a DBD. Etiological mechanisms, directions for future research, and clinical implications are discussed.

Understanding the mechanisms underlying the development of violence exposure sequelae is essential to providing effective treatments for traumatized youth. This longitudinal study examined the mediating role of posttraumatic stress in the relationship between violence exposure and psychopathology, and compared the mediated models by gender. Urban adolescents (n=1,358) were surveyed using the Social and Health Assessment. The proposed relationships were examined using Structural Equation Modeling. Posttraumatic stress fully mediated the relationships between victimization and depression and anxiety in girls, and partially so in boys. In addition, posttraumatic stress partially mediated the relationships between violence exposure and commission of violence in boys. Current findings support the longitudinal effects of violence exposure on adolescent mental health. Posttraumatic stress represents a unique mechanism for the development of psychopathology in girls and is also related to negative outcomes in boys. These findings have direct implications for prevention and rehabilitation efforts among violence exposed youth.
