One particular developmental task during adolescence is to regulate fluctuating moods to successfully transition through this period. The aim of this person-centered study was to identify distinct developmental trajectories of adolescent mood variability and to compare adolescents in different trajectories on changes in depressive symptoms, delinquency, and alcohol consumption in early to middle (ages 13-16) and middle to late adolescence (ages 16-20). Dutch adolescents (n = 482, 57.1% male) rated their daily emotions three weeks per year for five years using Internet daily diaries (ages 13-18). Day-to-day mood changes were calculated as an indicator of mood variability. Adolescents provided annual reports on depressive symptoms, delinquent acts, and alcohol consumption (ages 13-20). Results showed that most adolescents (88%) followed a trajectory characterized by decreases in mood variability (i.e., more stable moods). However, a minority (12%) followed a trajectory of increases in mood variability with a peak during middle adolescence. Adolescents with an increasing mood variability trajectory showed stable depressive and delinquency symptoms in early to middle adolescence compared with adolescents with a decreasing mood variability trajectory, who showed a decline in these symptoms. At age 16, there was a significant difference between the groups in depressive and delinquency symptoms, which stayed stable toward late adolescence. Although the two groups did not differ concerning alcohol consumption in early to middle adolescence, adolescents from the increasing mood variability class experienced less steep increases in alcohol use from middle to late adolescence compared with adolescents from the decreasing mood variability class.

A central assumption of identity theory is that adolescents reconsider current identity commitments and explore identity alternatives before they make new commitments in various identity domains (Erikson, 1968; Marcia, 1966). Yet, little empirical evidence is available on how commitment and exploration dynamics of identity formation affect each other across adolescence at the within-person level. Therefore, the current study (N = 494, M[subscript age] Time 1 = 13.3 years) examined reciprocal within-person longitudinal linkages between adolescents' identity exploration and identity commitment making in the interpersonal and educational identity domains. For this purpose, we constructed a multilevel type cross-lagged panel model from early to late adolescence (i.e., across 5 successive years). Results supported Erikson's (1968) hypothesis that adolescents reconsider current identity commitments and explore alternatives before they make strong commitments within the interpersonal identity domain across early to late adolescence. Within the educational identity domain, increasing identity commitment level and commitment fluctuations predicted less identity reconsideration over time. Our findings support identity theory, but indicate that the processes of identity formation might differ depending on the identity domain.

Empathy plays a key role in maintaining close relationships and promoting prosocial conflict resolution. However, research has not addressed the potential emotional cost of adolescents' high empathy, particularly when relationships are characterized by more frequent conflict. The present 6-year longitudinal study (N = 467) investigated whether conflict with parents predicted emotion dysregulation more strongly for high-empathy adolescents than for lower-empathy adolescents. Emotion dysregulation was operationalized at both the experiential level, using mood diary data collected for 3 weeks each year, and at the dispositional level, using annual self-report measures. In line with predictions, we found that more frequent adolescent-parent conflict predicted greater day-to-day mood variability and dispositional difficulties in emotion regulation for high-empathy adolescents, but not for average- and low-empathy adolescents. Mood variability and difficulties in emotion regulation, in turn, also predicted increased conflict with parents. These links were not moderated by empathy. Moreover, our research allowed for a novel investigation of the interplay between experiential and dispositional emotion dysregulation. Day-to-day mood variability predicted increasing dispositional difficulties in emotion regulation over time, which suggests that experiential dysregulation becomes consolidated into dispositional difficulties in emotion regulation. Moderated mediation analyses revealed that, for high-empathy adolescents, conflict was a driver of this dysregulation consolidation process. Finally, emotion dysregulation played a role in overtime conflict maintenance for high-empathy adolescents. This suggests that, through emotion dysregulation, high empathy may paradoxically also contribute to maintaining negative adolescent-parent interactions. Our research indicates that high empathy comes at a cost when adolescent-parent relationships are characterized by greater negativity.

We examined cross-cultural differences in (1) sibling power balance and (2) the associations between sibling power balance and internalizing and externalizing problems in three separate cross-cultural studies (early childhood, late childhood, and adolescence). The "early childhood samples" consisted of 123 Turkish and 128 Dutch mothers (mean age for children was 4.9 years). In the "late childhood samples," self-report data were collected from 124 Indian and 129 Dutch children (mean age 10.9 years). In the "adolescent samples" self-report data were collected from 165 ethnic Moroccan and 165 ethnic Dutch adolescents (mean age 15.2 years). In all studies, questionnaire data on sibling power imbalance and internalizing and externalizing problems were collected. Results showed only one significant cross-cultural difference in sibling power imbalance: The Indian sample reported more sibling power imbalance than the Dutch. Links between sibling power imbalance and problem behavior were highly similar between the different cultural samples. The only significant difference was a stronger impact of sibling power imbalance on externalizing problems for the Dutch compared to the Turkish sample. Concluding, few cross-cultural differences were found in sibling power imbalance. Across cultures and age groups, more sibling power imbalance was linked to more internalizing and externalizing problems.

This study aimed to gain a better understanding of the normative declines in adolescent disclosure and maternal knowledge over the course of adolescence, by assessing the underlying monitoring processes. Multilevel structural equation models were applied to 15 assessments among 479 families across 5 years (13 years at T1, 57% boys, 11% low socioeconomic status). Developmental declines in mother-perceived disclosure and knowledge were observed, which were partially explained by processes operating at the level of the family unit. On average, mothers were more knowledgeable in weeks with more disclosure and more solicitation, and adolescent disclosure was higher in weeks with more maternal solicitation and less control. The effect sizes and even the directions of these within-family correlations varied between families, however. This heterogeneity was partially explained by the level of maternal control and adolescent disclosure, and by the families' socioeconomic status. Within-family fluctuations in knowledge and disclosure were also correlated with fluctuations in relationship quality and adolescent and mother mood. Overall, these within-family processes explained up to 14% of the normative developmental decline in disclosure and 19% of the decline in knowledge. This study thus suggests that a wide variety in monitoring processes may drive normative declines in adolescent disclosure and maternal knowledge.

Identity formation is one of the key developmental tasks in adolescence. According to Erikson (1968) experiencing identity uncertainty is normative in adolescence. However, empirical studies investigating identity uncertainty on a daily basis are lacking. Hence, studying individual differences in daily certainty (i.e., identity commitment levels) and uncertainty (i.e., identity commitment fluctuations and identity reconsideration) in the identity formation process may advance our knowledge about the extent to which adolescents' identity uncertainty is part of normative identity development. Therefore, this longitudinal study examined heterogeneity in certainty and uncertainty dynamics of adolescents' daily identity formation using a longitudinal microlevel approach. Dutch adolescents (N = 494; M[subscript age] = 13.03 years at T1; 56.7% boys) reported on 2 key dimensions of identity formation (i.e., commitment and reconsideration) in both the educational and interpersonal domain on a daily basis for 3 weeks within 1 year, across 5 successive years. Multivariate latent class growth analyses suggested both in the educational and interpersonal identity domain a class of adolescents displaying a "crisis-like" identity formation process, and an "identity synthesis" class. Classes revealed differential development of (global and school) anxiety, aggression, and best friend support. Taken together, the present study confirmed Erikson's notion that experiencing daily identity uncertainty is common during adolescence. However, a substantial amount of adolescents also showed a process toward identity maturation already during adolescence.

Poor reciprocity is a defining feature of an autism spectrum disorder (ASD). In the current study, we examined the reliability and validity of the Interactive Drawing Test (IDT), a new instrument to assess reciprocal behavior. The IDT was administered to children and adolescents with ASD (n = 131) and to a typically developing group (n = 62). The IDT had excellent inter-rater reliability and moderate to good test-retest reliability. The results showed clearly distinctive response patterns in the ASD group compared to the typically developing group, independent of verbal IQ and age. Convergent validity of the IDT was low. Sensitivity and the predictive accuracy of the IDT for detailed levels of reciprocal behavior in autism are discussed.

This longitudinal study explores differences between native Dutch and immigrant Moroccan adolescents in the relationship between internalizing and externalizing problems across time. By using generalized estimating equations (GEE), the strength and stability of associations between internalizing and externalizing problems in 159 Moroccan and 159 Dutch adolescents was studied over a period of 4 years. No differences in strength of co-occurring problems were found between Moroccan and Dutch adolescents. However, for Moroccan adolescents, associations between problems increased over time, whereas in Dutch adolescents, associations remained stable. The increase of co-occurring problems may be a result of undertreatment and increasing complexity of problems in Moroccans during adolescence. The results of this study imply that investigating processes leading to co-occurring problems in subgroups of adolescents, such as immigrant youths, is needed to optimize prevention and intervention efforts.

This study highlights differences in cognitive strategies in children and adolescents with and without autism spectrum disorders (n = 52) on a verbal fluency task (naming as many words as possible (e.g. animals) within 60 s). The ability to form clusters of words (e.g. farm animals like "cow-horse-goat") or to switch between unrelated words (e.g. "snake" and "cat") was analyzed using a coding method that more stringently differentiates between these strategies. Results indicated that children and adolescents with autism spectrum disorders switched less frequently, but produced slightly larger clusters than the comparison group, resulting in equal numbers of total words produced. The currently used measures of cognitive flexibility suggest atypical, but possibly equally efficient, fluency styles used by individuals with autism spectrum disorders.

While stress is a common experience for parents caring for a child with a developmental disability, current measures fail to distinguish between general stress in parents and the demands of parenting and perceptions of parenting skills (parenting stress). This study examined differences in "parenting stress" reported by parents of children with autism and typically developing children. This study examined the role of child characteristics (age, autism severity, child quality of life and problem behaviour) on parenting stress in 150 parents of cognitively able children and adolescents with autism. The results revealed that child hyperactivity was the only factor significantly related to parenting stress in parents of children with autism, overruling measures of autism severity and child quality of life. This finding indicates the significant influence of problematic behaviours on parenting demands and perceptions of parenting skills in parents of children with autism, over other child characteristics conceived as within the parent's control. Study implications for future research are discussed.

This 4-year study examined longitudinal interplays between adolescents' and mothers' self-reported empathic concern (EC) and perspective taking (PT). We investigated (a) whether adolescents' EC predicted rank-order change in their PT over time, or vice versa; (b) whether mothers' empathy predicted relative increases in adolescents' empathy; (c) whether adolescent gender moderated the over-time links from mothers' to adolescents' empathy; and (d) whether the rank-order stability of EC and PT over time differed within and between respondents. Adolescents' EC positively predicted their PT over time, but not vice versa. Mothers' PT positively predicted adolescent PT over time for girls, but not for boys. The rank-order stability of adolescents' EC was greater than their PT. Maternal PT and EC were equally stable and were more stable than in adolescents. This study contributes the first empirical evidence that the developmental order of adolescents' empathy runs from affective to cognitive empathy, in contrast to prior theoretical and experimental literature that has emphasized the reverse direction. It further provides the 1st longitudinal evidence of intergenerational empathy transmission. These findings support the notion that adolescence is a developmentally sensitive period for PT.

Background: It is well documented that friends' externalizing problems and negative parent-child interactions predict externalizing problems in adolescence, but relatively little is known about the role of siblings. This four-wave, multi-informant study investigated linkages of siblings' externalizing problems and sibling-adolescent negative interactions on adolescents' externalizing problems, while examining and controlling for similar linkages with friends and parents. Methods: Questionnaire data on externalizing problems and negative interactions were annually collected from 497 Dutch adolescents ("M" = 13.03 years, "SD" = 0.52, at baseline), as well as their siblings, mothers, fathers, and friends. Results: Cross-lagged panel analyses revealed modest unique longitudinal paths from sibling externalizing problems to adolescent externalizing problems, for male and female adolescents, and for same-sex and mixed-sex sibling dyads, but only from older to younger siblings. Moreover, these paths were above and beyond significant paths from mother-adolescent negative interaction and friend externalizing problems to adolescent externalizing problems, 1 year later. No cross-lagged paths existed between sibling-adolescent negative interaction and adolescent externalizing problems. Conclusions: Taken together, it appears that especially older sibling externalizing problems may be a unique social risk factor for adolescent externalizing problems, equal in strength to significant parents' and friends' risk factors.

Background: The sociocommunicative problems in autism spectrum disorder (ASD) are traditionally linked to impairments in Theory of Mind (ToM), the ability to ascribe mental states to others. Although ToM impairments are consistently reported in young children with ASD, findings on more advanced ToM understanding in older individuals with high-functioning ASD (HFASD) are less straightforward. Therefore, we assessed the advanced ToM abilities of a large sample of school-aged children and adolescents with HFASD ("n" = 194; 6-20 years) and compared them to a typically developing (TD) comparison group ("n" = 60). Methods: Participants' advanced ToM was assessed with five social stories containing second-order false beliefs, display rules, double bluff, faux pas, and sarcasm. Results: Participants with HFASD performed equally well on each of the ToM stories as their TD peers. Consistent age effects were noticed with adolescents outperforming the children. Furthermore, advanced ToM was positively associated with participants' age, verbal abilities, and general reasoning abilities. Conclusions: Counter to what the ToM theory of ASD would predict, school-aged children and adolescents with HFASD seem to be able to master the theoretical principles of advanced mental state reasoning. However, they may still fail to apply these theoretical principles during everyday social interactions. (Contains 3 tables.)

This study examines sex differences in the risk threshold for adolescent delinquency. Analyses were based on longitudinal data from the Pittsburgh Youth Study (n = 503) and the Pittsburgh Girls Study (n = 856). The study identified risk factors, promotive factors, and accumulated levels of risks as predictors of delinquency and nondelinquency, respectively. The risk thresholds for boys and girls were established at two developmental stages (late childhood: ages 10-12 years, and adolescence: ages 13-16 years) and compared between boys and girls. Sex similarities as well as differences existed in risk and promotive factors for delinquency. ROC analyses revealed only small sex differences in delinquency thresholds, that varied by age. Accumulative risk level had a linear relationship with boys' delinquency and a quadratic relationship with girls' delinquency, indicating stronger effects for girls at higher levels of risk.

Qualitative differences in social interaction style exist "within" the autism spectrum. In this study we examined whether these differences are associated with (1) the severity of autistic symptoms and comorbid disruptive behavior problems, (2) the child's psycho-social health, and (3) executive functioning and perspective taking skills. The social interaction style of 156 children and adolescents (6-19 years) with high-functioning autism spectrum disorder (HFASD) was determined with the Wing Subgroups Questionnaire. An active-but-odd social interaction style was positively associated with symptoms of autism, attention deficit and hyperactivity. Furthermore, an active-but-odd social interaction style was negatively associated with children's psycho-social health and positively with executive functioning problems. Social interaction style explains part of the heterogeneity among children with HFASD. (Contains 2 tables.)

This study reports on a new false belief measure in a sample of 124 children and adolescents with or without high functioning autism (HFASD). In the classic paradigm, a participant predicts in which of two discrete locations a deceived protagonist will look for an object. In the current Sandbox task, the object is buried and reburied in a sandbox, thus creating a continuum between locations. Compared to typically developing individuals (n=62), those with HFASD (n=62) showed a larger egocentric bias on the Sandbox task. They failed to take the protagonist's false belief into account, despite their adequate ability to infer advanced mental states. This indicates that sensitive measures can reveal subtle first order Theory of Mind impairments in HFASD individuals. (Contains 3 figures and 2 tables.)

Spending leisure time with deviant peers may have strong influences on adolescents' delinquency. The current 3-wave multi-informant study examined how parental control and parental prohibition of friendships relate to these undesirable peer influences. To this end, annual questionnaires were administered to 497 Dutch youths (283 boys, mean age = 13 years at baseline), their best friends, and both parents. Cross-lagged panel analyses revealed strong longitudinal links from contacts with deviant peers to adolescent delinquency, but not vice versa. Parent-reported prohibition of friendships positively predicted contacts with deviant peers and indirectly predicted higher adolescent delinquency. Similar indirect effects were not found for parental control. The results suggest that forbidden friends may become "forbidden fruit," leading to unintended increases in adolescents' own delinquency.

This study examined whether the quality of parent-adolescent interactions moderate the association between stressful life events and internalizing and externalizing problems in referred adolescents (N = 101, M age 13.41 years, SD = 1.81). Adolescents and their parents reported on psychological problems at the time of referral and 4 years later. At follow-up parents reported on stressful life events and an interaction task was conducted to observe autonomy and relatedness promoting behaviors. For adolescents exposed to stressful events, levels of internalizing and externalizing problems went up except if observed parent-adolescent interactions were characterized by high autonomy and relatedness. The results implied that autonomy and relatedness protect adolescents against the deleterious effects of stressful life events. These findings build on previous research showing for psychologically vulnerable adolescents that parenting that promotes autonomy while maintaining relatedness is associated with resilience in times of stress.

The self-presentation skills of children and adolescents with high-functioning autistic spectrum disorder (HFASD) and typically developing (TD) controls were compared, in response to both hypothetical and real life situations. In both situations, 26 HFASD and 26 TD participants were prompted to describe themselves twice, first in a baseline condition, and later in a goal-directed condition where specific information was given about the preferences and demands of the audience. Confirming and extending previous research, both TD and HFASD participants exhibited a tendency to be more positive when describing themselves in a goal-directed condition. However, HFASD participants were less strategic than TD participants in responding to the information they were given about the audience preferences and demands. Possible explanations and implications of the results are discussed. (Contains 4 tables.)

The authors explored the utility of the Difficulties in Emotion Regulation Scale (DERS) in assessing adolescents' emotion regulation. Adolescents (11-17 years; N = 870) completed the DERS and measures of externalizing and internalizing problems. Confirmatory factor analysis suggested a similar factor structure in the adolescent sample of the authors as demonstrated previously among adults. Furthermore, results indicated no gender bias in ratings of DERS factors on three scales (as evidenced by strong factorial gender invariance) and limited gender bias on the other three scales (as evidenced by metric invariance). Female adolescents scored higher on four of six DERS factors than male adolescents. DERS factors were meaningfully related to adolescents' externalizing and internalizing problems. Results suggest that scores on the DERS show promising internal consistency and validity in a community sample of adolescents. (Contains 6 tables.)

Background: Psychopathology in youth appears to be linked to deficits in regulating affective responses to stressful situations. In children, high-quality parental support facilitates affect regulation. However, in adolescence, the role of parent-child interaction in the regulation of affect is unclear. This study examined physiological reactivity to and recovery from stress in adolescents at risk for psychopathology, and their associations with internalising and externalising problems and parent-adolescent interactions. Methods: A total of 99 adolescents (M = 13.57 years, SD = 1.83) with a history of mental health problems underwent the Alarm Stress Task and were reunited with their primary caregiver after the stressor, while the physiological responses of the parasympathetic (respiratory sinus arrhythmia) and sympathetic (pre-ejection period) systems were measured. The quality of parent-adolescent interaction was determined from observations of secure-base seeking and providing during the task. Affect regulation was measured as physiological reactivity and recovery after the stressor. Results: Adolescents with high levels of externalising problems and low levels of secure-base support showed weaker parasympathetic reactivity and recovery. Higher level of adolescent secure-base seeking was associated with stronger sympathetic reactivity and recovery. Conclusions: Secure-base interactions between parents and adolescents facilitate physiological regulation of stress, especially for adolescents with externalising symptomatology.

Background: This study examined the relation between stress and change in emotional and behavioural problems in children and adolescents referred for mental health services. Method: At three waves across four years, children and their parents (N = 310, mean age at the first wave = 11.26 years, SD = 3.18) reported emotional and behavioural problems, as well as stressful life events (parent report) and perceived stress (child report). Results: Major life events before referral were associated with higher levels of parent-reported internalising and externalising problems at referral. Life events after referral were associated with a slower recovery from internalising problems. The associations between stressful life events and the course of parent- and self-reported problems were mediated by children's subjective feelings of stress. Conclusion: Stressful life events appear to interfere with recovery from internalising problems in the years after referral through increasing the experience of stress in daily life.

Background: Health risk behaviors like substance use (alcohol, tobacco, soft/hard drugs) and risky sexual behavior become more prevalent in adolescence. Children with behavior problems are thought to be prone to engage in health risk behaviors later in life. It is, however, unclear which problems within the externalizing spectrum account for these outcomes. Methods: Three hundred and nine children were followed from age 4/5 years to 18 years (14-year follow-up). Level and course of parent-rated opposition, physical aggression, status violations and property violations were used to predict adolescent-reported substance use and risky sexual behavior at age 18 years. Results: Both level and change in physical aggression were unique predictors of all forms of adolescent health risk behavior. Levels of status violations predicted smoking and soft drug use only, while change in property violations predicted each of the health risk behaviors. The links between opposition and health risk behaviors were accounted for by co-occurring problem behaviors. Conclusions: Of externalizing problems, physical aggression is the best predictor of adolescent substance use and risky sexual behavior from childhood onwards. Possible explanations and implications of these findings, and future research directions are discussed.

Background: This study described similarities and differences in the 5-year stability and change of problem behaviour between youths attending schools for children with mild to borderline (MiID) versus moderate intellectual disabilities (MoID). Methods: A two-wave multiple-birth-cohort sample of 6 to 18-year-old was assessed twice across a 5-year interval using the Developmental Behaviour Checklist Primary Carer version (n = 718) and Teacher version (n = 313). Results: For most types of problem behaviour youths with MiID and MoID showed similar levels of stability of individual differences, persistence and onset of psychopathology. Whenever differences were found, youths with MoID showed the highest level of stability, persistence and onset across informants. Mean levels of parent-reported, but not teacher-reported, problem behaviour, regardless of level of intellectual disability, decreased during the 5-year follow-up period. Conclusions: Youths with MoID and MiID are at risk for persistent psychopathology to a similar degree. Different informants showed to have a different evaluation of the level and the amount of change of problem behaviour, and should be considered complementary in the diagnostic process.

Six types of antisocial and delinquent behaviors (e.g., property destruction and authority avoidance) were assessed in 526 youths (11 to 24 years of age) with mild to borderline intellectual disabilities and 1,030 11- to 18-year-olds without intellectual disabilities. Overall, 10% to 20% of youths with intellectual disabilities exhibited some type of antisocial and delinquent behavior, which were quite persistent over a 5-year period. Youths who exhibited one type of antisocial and delinquent behavior were likely to also exhibit other types of such behaviors. Being male, younger, and having behavioral problems particularly predicted these behaviors across a 5-year period. Overall, boys but not girls with intellectual disabilities exhibited antisocial and delinquent behaviors more often than peers without intellectual disabilities. Clinical implications and implications for future research are discussed.

Objective: To determine the extent to which the Youth Self-Report (YSR) can be used to assess emotional and behavioral problems in adolescents with intellectual disabilities (IDs). Method: In 2003, 281 11- to 18-year-olds with IDs (IQ greater than or equal to 48) completed the YSR in an interview, and in 1993, 1,047 non-ID adolescents completed the YSR themselves. Parents completed the Child Behavior Checklist (CBCL). The ID sample was split into lower (IQ 48-69) and higher (IQ greater than or equal to 70) IQ groups. Cronbach's alpha values of the YSR scales and (intraclass) correlation coefficients between and within YSR and CBCL scale scores were calculated to determine parent-adolescent agreement and YSR construct validity, which were compared between samples. Mean YSR scale scores were compared between adolescents with ID with and without psychiatric symptoms. Results: Cronbach's alpha, parent-adolescent agreement, and indications of construct validity were about similar in all samples, although discriminant validity was somewhat weaker in the lower IQ group. Mean scale scores were 1.5 to 2.0 times higher for ID adolescents with psychiatric symptoms. Conclusions: The YSR seems applicable in youth with an IQ greater than or equal to 48. Further research is needed to refine and confirm these findings and the factor structure of the YSR in adolescents with ID and to differentiate between adolescents with moderate and mild IDs. (Contains 3 tables.)

Background: Parents of children and adolescents with both intellectual disabilities (ID) and psychopathology often experience high levels of parenting stress. To support these parents, information is required regarding the types of support they need and whether their needs are met. Method: In a sample of 745 youths (aged 10-24 years) with moderate to borderline ID, 289 parents perceived emotional and/or behavioural problems in their child. They were asked about their needs for support and whether these needs were met. Logistic regression analysis revealed the variables associated with both needing and receiving specific types of support. In addition, we asked those parents who had refrained from seeking support about their reasons. Results: Most parents (88.2) needed some supports, especially a friendly ear, respite care, child mental health care and information. Parents who perceived both emotional and behavioural problems in their child needed support the most. In addition, parents whose child had any of these problems before the past year, who worried most about their child and suffered from psychopathology themselves, more often needed support. Parents of children with moderate ID or physical problems especially needed "relief care", that is, respite care, activities for the child and practical/material help. The need for a friendly ear was met most often (75.3), whereas the need for parental counselling was met least often (35.5). Not receiving support despite having a need for it was primarily related to the level of need. Parents who indicated to have a stronger need for support received support more often than parents who had a relatively low need for support. The parents' main reasons for not seeking support concerned their evaluation of their child's problems (not so serious or temporary), not knowing where to find support or wanting to solve the problems themselves first. Conclusions: Most parents had various support needs that were frequently unmet. Service providers should especially aim at providing information, activities, child mental health care and parental counselling. Furthermore, parents need to be informed about where and how they can obtain what kind of support. A case manager can be of help in this.

This article describes the average and group-based developmental trajectories of aggression, opposition, property violations, and status violations using parent reports of externalizing behaviors on a longitudinal multiple birth cohort study of 2,076 children aged 4 to 18 years. Trajectories were estimated from multilevel growth curve analyses and semiparametric mixture models. Overall, males showed higher levels of externalizing behavior than did females. Aggression, opposition, and property violations decreased on average, whereas status violations increased over time. Group-based trajectories followed the shape of the average curves at different levels and were similar for males and females. The trajectories found in this study provide a basis against which deviations from the expected developmental course can be identified and classified as deviant or nondeviant.

Analysis of parent and teacher Developmental Behavior Checklist (DBC) ratings on a combined sample of 1,536 Dutch and Australian children (ages 3-22) with mild to profound intellectual disabilities produced five subscales: Disruptive/Antisocial, Self-Absorbed, Communication Disturbance, Anxiety, and Social Relating. Internal consistency of the subscales ranged from .66 to .91. (Contains references.) (Author/CR)

PurposeTo investigate, in adolescents referred for psychiatric services, the associations of initial self-esteem and family functioning with level and change of quality of life (QoL) over a 3-year period, over and above the effect of their emotional problems.MethodsOf 1648 eligible 13-18 years old patients attending the child and adolescent psychiatric clinic (CAP) at least once, 717 (54.8% females) were enrolled at baseline (a response rate of 43.5%). Self- and parent reports on the McMaster Family Assessment Device were obtained. Adolescents reported self-esteem on the Rosenberg Scale, and emotional problems on the Symptom Check List-5. Adolescents completed the Inventory of Life Quality in Children and Adolescents (ILC). After 3 years, 570 adolescents again completed the ILC, and for 418 adolescents parent information was available. The longitudinal analysis sample of 418 adolescents was representative of the baseline sample for age, gender, emotional problems, and QoL. We used modified growth-model analysis, adjusted for SES, age, gender and time of contact with CAP, where residual variances for ILC at baseline and follow-up were fixed to 0.ResultsA poorer family functioning at baseline, reported by parents, was significantly associated with worsening QoL during the 3 years follow-up period (p = 0.001).ConclusionsParents have important knowledge about their families that may reflect long-term influences on QoL development in adolescent psychiatric patients. Health care providers and policy makers should optimize treatment outcomes by addressing family functioning in adolescents with emotional problems.
