This study aimed to report the effect of a 6-week light-active versus moderate-active physical activity intervention embedded in a multimodal day treatment program on selected measures of cognitive control (i.e., response inhibition, error processing, and cognitive interference) and trait impulsivity. A randomized controlled design was implemented, including male multi-problem young adults (aged 18-27) assigned to either light-active ( N  = 12) or moderate-active physical activity lessons ( N  = 11). A repeated measures design was used to examine treatment effects between the two groups over time on response inhibition, error processing, and cognitive interference (measured respectively with a Go/NoGo task, a Flanker task, and the Stroop) and trait impulsivity (measured with the Dutch Baratt Impulsiveness Scale). Cognitive control, but not trait impulsivity, improved over time. Specifically, enhancements in inhibition and reduced cognitive interference were observed after 6 weeks. Error processing did not improve, but we did observe improved performance on an error-processing task. No interaction with physical activity intensity was found, suggesting similar treatment effects regardless of intensity. Results should be interpreted with caution due to several limitations, including the small sample size. Overall, due to current limitations (i.e., physical activity embedded in a larger treatment program, small sample size at follow-up, and low intervention adherence), it is not possible to draw any definite conclusions. However, the current findings contribute to a growing body of evidence suggesting potential benefits of physical activity (embedded in a multi-modal day treatment program) in the enhancement of cognitive control deficits in at-risk populations, independent of exercise intensity., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Procedural justice literature proposes that when individuals perceive their treatment by criminal justice authorities as more procedurally just, they will be more likely to view those authorities as legitimate and, in turn, show more compliant behavior. Knowledge on potential determinants of procedural justice is, therefore, crucial. Research suggests that prior perceptions of procedural justice may influence later judgements of procedural justice. The current study used data from the Prison Project, including information on detainees' perceptions of their treatment by the police, the judge, the prison staff, the probation officer, and the lawyer. The findings show that detainees perceive the treatment by the lawyer as most procedurally just, while they evaluate the treatment by the police as least procedurally just. Further, how detainees experience the procedurally just treatment by the police is associated with how they feel treated by other authorities at a later stage in the criminal justice system., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The literature on procedural justice has been mainly focused on examining whether a fair and respectful treatment affects justice-involved individuals' legitimacy evaluations and their behavior. It is, however, equally important to examine (a) the role that perceptions of procedural justice play for individuals in their encounters with criminal justice authorities and (b) what makes individuals feel treated procedurally (un-)just. In this qualitative study, semi-structured interviews were conducted with 35 detainees in a Dutch prison, asking questions about their encounters with police officers, prison staff, judges, and probation officers. The findings showed that the majority of detainees raised issues of procedural justice, indicating that procedural justice plays an important role for them. In addition, five elements primarily shaped detainees' perceptions of procedural justice: (1) trustworthy motives, (2) interpersonal treatment, (3) neutrality, (4) participation, and (5) agency and process information. These elements of procedural justice were mentioned after encounters with most authorities., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Previous studies indicate a positive association between physical activity and cognitive control in sedentary but healthy adults, yet not much is known about physical activity levels in multi-problem young adults. We examined the level of self-reported free-living physical activity (i.e., MET minutes per week) in an ecologically valid sample of young adults facing multiple problems, including unemployment, lack of education, frequent substance use, and history of delinquency. We compared cognitive control with an age- and sex-matched control sample. Additionally, the association between physical activity and cognitive control (i.e., response inhibition, error processing, interference effect) in the multi-problem group was examined. Physical activity and cognitive control were measured with the International Physical Activity Questionnaire-Long Form and three cognitive control experiments (i.e., Flanker, Go/NoGo, Stroop), respectively. With M = 4428 Metabolic Equivalents (METs), our multi-problem sample ( n = 63) showed physical activity levels similar to the age- and sex-matched control sample from the general population ( n = 62). The multi-problem young adults also showed impaired cognitive control indexed as decreased response inhibition and decreased Flanker correctness effect compared to their peers. We could not find an association between self-reported physical activity and cognitive control in the multi-problem sample. Due to the small sample size, results should be interpreted with caution. However, future dose-response studies could still use these results to further examine if within-individual increased physical activity may possibly lead to improved cognitive control in (already relatively active) multi-problem young adults., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 van der Sluys, Marhe, van der Laan, Popma and Scherder.)

Previous research has shown an association between cognitive control deficits and problematic behavior such as antisocial behavior and substance use, but little is known about the predictive value of cognitive control for treatment outcome. The current study tests whether selected markers of baseline cognitive control predict (1) treatment completion of a day treatment program involving a combination of approaches for multiproblem young adults and (2) daytime activities a year after the start of treatment, over and above psychological, social, and criminal characteristics. We assessed individual, neurobiological, and neurobehavioral measures, including functional brain activity during an inhibition task and two electroencephalographic measures of error processing in 127 male multiproblem young adults (age 18-27 years). We performed two hierarchical regression models to test the predictive power of cognitive control for treatment completion and daytime activities at follow-up. The overall models did not significantly predict treatment completion or daytime activities at follow-up. However, activity in the anterior cingulate cortex (ACC) during response inhibition, years of regular alcohol use, internalizing problems, and ethnicity were all significant individual predictors of daytime activity at follow-up. In conclusion, cognitive control could not predict treatment completion or daytime activities a year after the start of treatment over and above individual characteristics. However, results indicate a direct association between brain activity during response inhibition and participation in daytime activities, such as work or school, after treatment. As adequate baseline inhibitory control is associated with a positive outcome at follow-up, this suggests interventions targeting cognitive control might result in better outcomes at follow-up.

This study increases knowledge on effectiveness of treatment for extremely violent (EV) youth by investigating their response to multisystemic therapy (MST). Using data of a randomized controlled trial on effectiveness of MST, we investigated differences in treatment response between EV youth and not extremely violent (NEV) youth. Pre- to post-treatment comparison indicated MST was equally effective for EV and NEV youth, whereas treatment as usual was not effective for either group. Growth curves of within-treatment changes indicated EV youth responded differently to MST than NEV youth. The within-treatment change was for EV youth non-linear: Initially, they show a deterioration; however, after one month, EV juveniles respond positively to MST, indicating longer lasting, intensive programs may be effective in treating extreme violence.

This study examined the influence of treatment motivation on posttreatment effectiveness of an outpatient, individual social skills training for juvenile delinquents imposed as a penal sanction. Propensity score matching was used to match a control group of juveniles receiving treatment as usual ( n = 108 of total N = 354) to a treatment group of juveniles receiving Tools4U, a social skills training with a parental component ( N = 115). Treatment motivation was examined as a moderator and predictor of treatment effects on impulsivity, social perspective-taking, social problem-solving, lack of critical reasoning, developmental task-related skills, and parenting skills. Treatment effects were mostly consistent across juveniles with different levels of treatment motivation. Only one moderating effect was found on active tackling (i.e., actively addressing problems), and predictive effects were found on seeking social support, cognitive empathy, hostile intent attribution, and self-centeredness. Implications for further research are discussed.

This study examined the New Perspectives Aftercare Program (NPAP) for serious juvenile and young adult offenders in The Netherlands. Participants (n = 127) were randomly assigned to NPAP (n = 66) or existing aftercare services ("treatment as usual" [TAU], n = 61). The aim was to determine whether NPAP was effective in decreasing cognitive distortions and criminal thinking patterns and increasing prosocial skills of the juveniles compared with TAU. No direct intervention effects were found on any of the outcome measures. Moderator analyses, however, showed several interaction effects of ethnicity and coping skills for both NPAP and TAU youths. Furthermore, NPAP dropouts displayed significantly more indirect aggression at posttest compared with youths dropping out from TAU. Possible explanations for the mostly null effects are discussed, including implications for further research, policy, and practice., (© The Author(s) 2015.)

A humane and fair treatment of prisoners is of intrinsic value in itself, and is generally acclaimed to reduce prisoners' psychological distress and misconduct in prison, and their criminal behavior after release from prison. To create a more just prison climate, scholars have emphasized the importance of correctional staff. However, there is a lack of empirical research on the relationship between correctional officers' characteristics and prisoners' perceptions of a just treatment in prison. Our study fills this gap in knowledge. Data were used from (a) the Prison Project, a large-scale study in which prisoners held in all Dutch remand centers were surveyed (n = 1,610) and (b) the Dutch Correctional Staff Survey 2011 (n = 690). Multilevel analyses showed that prisoners perceived their treatment in prison as more procedurally just in units where there are more female officers, where officers held more positive attitudes toward rehabilitation, and where there is a higher officer-to-inmate ratio., (© The Author(s) 2013.)

Previous research has focused mainly on determining the effectiveness of suspended sentences compared with other sentences, and seldom on understanding to what extent the different types of suspended sentences reduce recidivism rates. This study examined reconviction rates of offenders (N = 1,258) who received fully or partly suspended prison sentences, with or without special conditions, in 2006 in two of the largest court districts in the Netherlands. Cox proportional hazard models revealed no difference in reconviction rates between fully and partly suspended prison sentences, with and without special conditions. However, suspended sentences without special conditions had significantly lower reconviction rates compared with special conditions that were solely control-orientated. Although there are indications that certain types of suspended sentences reduced reconviction rates more than other types, more rigorous research is still required., (© The Author(s) 2013.)

Background: A neurobiological perspective has become accepted as a valuable approach for understanding anti-social behaviour. There is literature to suggest that, in non-offending populations, psychological treatments affect both neurobiological measures and clinical presentation. A theoretical position to this effect has been adopted with respect to offender treatment, but there has been no systematic review of empirical literature on this point., Aims: This study aimed to ascertain from published literature firstly whether there is evidence of change in neuropsychological or physiological measures after behavioural treatments/programmes for people with anti-social behaviour and secondly whether these neurobiological changes are associated with behavioural change., Method: A systematic search strategy was formulated to include studies considering 'neurobiological factors', 'anti-social population', 'treatment' and 'treatment outcome'. The Maryland Scientific Methods Scale was used to select relevant studies of sufficient methodological quality., Results: Eleven studies were found, only one with adults. Overall, the values of specific neurobiological risk factors, particularly of basal cortisol, become less abnormal following intervention. There was some evidence for a link between change in neurobiological functioning and behavioural improvement., Conclusions: Findings, although provisional, may provide new insights into the underlying mechanisms of interventions for anti-social behaviour. Future studies that include pre-treatment neurobiological assessment could help reveal physical vulnerabilities that interventions should target to improve treatment efficacy, and provide for objective, independent corroboration of change., (Copyright © 2014 John Wiley & Sons, Ltd.)

This review focuses on the predictive value of neurobiological factors in relation to cognitive-behavioral therapy outcome among individuals with antisocial behavior. Ten relevant studies were found. Although the literature on this topic is scarce and diverse, it appears that specific neurobiological characteristics, such as physiological arousal levels, can predict treatment outcome. The predictive value of neurobiological factors is important as it could give more insight into the causes of variability in treatment outcome among individuals with antisocial behavior. Furthermore, results can contribute to improvement in current treatment selection procedures and to the development of alternative treatment options., (© The Author(s) 2013.)

Multisystemic Therapy (MST) is a well-established intervention for juvenile delinquents and/or adolescents showing social, emotional and behavioral problems. A multilevel meta-analysis of k=22 studies, containing 332 effect sizes, consisting of N=4066 juveniles, was conducted to examine the effectiveness of MST. Small but significant treatment effects were found on delinquency (primary outcome) and psychopathology, substance use, family factors, out-of-home placement and peer factors, whereas no significant treatment effect was found for skills and cognitions. Moderator analyses showed that study characteristics (country where the research was conducted, efficacy versus effectiveness, and study quality), treatment characteristics (single versus multiple control treatments and duration of MST treatment), sample characteristics (target population, age, gender and ethnicity) and outcome characteristics (non-specific versus violent/non-violent offending, correction for pretreatment differences, and informant type) moderated the effectiveness of MST. MST seems most effective with juveniles under the age of 15, with severe starting conditions. Furthermore, the effectiveness of MST may be improved when treatment for older juveniles is focused more on peer relationships and risks and protective factors in the school domain., (Copyright © 2013 Elsevier Ltd.

Background: Given the high prevalence of mental health problems among prisoners, knowledge on its determinants is important. Prior cross-sectional studies suggest that procedurally just treatment within prison is a significant predictor; however, longitudinal research is lacking., Aim: The aims of this study were to examine (1) the longitudinal relationship between prisoners' perceptions of procedural justice--including fairness, respect, humanity and relationships with officers--and their mental health and (2) the moderating role of coping style in this relationship., Methods: Data were obtained from the Prison Project, a longitudinal study of adult male prisoners in the Netherlands, interviewed both 3 weeks and 3 months after their reception into pre-trial detention (N = 824). A cross-lagged structural equation model was employed to investigate associations., Results: Prisoners who reported experiencing a higher level of procedural justice 3 weeks after their arrival in custody reported fewer mental health problems after 3 months. No evidence was found that coping style moderated this relationship., Conclusions: These findings suggest a causal relationship between procedural justice and psychological well-being. Fair and respectful treatment of prisoners is a predictor not only of prison order and prisoners' compliance but also of prisoners' psychological well-being., (Copyright © 2013 John Wiley & Sons, Ltd.)

This study examined the predictive validity of the Washington State Juvenile Pre-Screen Assessment (WSJCA pre-screen) in the Netherlands. Previous research conducted in the United States showed the predictive validity of the WSJCA pre-screen to be modest, as is the case with the predictive validity of most other risk assessment instruments for juveniles. Therefore, it was also examined whether the predictive validity of the WSJCA pre-screen can be improved by modifying the scoring procedure. The sample consisted of 520 youths who had been referred to the juvenile probation service by court. The present study showed the predictive validity of the WSJCA pre-screen in the Netherlands to be modest too, with an area under the receiver operating characteristic curve (AUC) of .625. Modifying the scoring procedure by means of chi-squared automatic interaction detector analyses significantly improved the predictive validity to an AUC of .702. The modified scoring procedure is time-saving because only variables that uniquely contribute to the prediction of recidivism are included, which at the same time leads to a more accurate prediction of recidivism.

It is important to examine whether general risk-assessment instruments developed for nonsex offenders can also be applied to sex offenders, because juvenile sex offenders are much more likely to reoffend with a nonsexual offense than a sexual offense. This study examined to what extent the Washington State Juvenile Court Prescreen Assessment (WSJCPA) can be used to assess the risk for general recidivism among different types of juvenile sex offenders. The predictive validity of the WSJCPA was examined separately for the following subgroups: boys convicted for a misdemeanor sexual offense against a peer (n = 381), boys convicted for a felony sexual offense against a peer (n = 282), boys convicted for a sexual offense against a younger child (n = 521), and girls convicted for a sexual offense (n = 71) and two comparison groups of male (n = 15,155) and female (n = 5,811) juvenile nonsex offenders. The area under the receiver operating characteristic curve scores for general recidivism ranged between .64 and .73. The WSJCPA proved to be at least equally predictive of general offending among juvenile sex and nonsex offenders groups.

Objective: The aim of the present study was to determine whether psychopathic traits act as a predictor and/or moderator of the effectiveness of Multisystemic Therapy (MST)., Method: The sample included N = 256 adolescents (188 boys and 68 girls) referred for conduct problems, randomized to MST or Treatment As Usual (TAU). The mean age was 16 years (SD = 1.31). Assessments were carried out before and immediately after treatment (6 months later). Three psychopathic traits (callous/unemotional traits, narcissism, and impulsiveness) were assessed with parent reports. Adolescents and parents were informants on externalizing problems., Results: MST was more effective than TAU in decreasing externalizing problems for the "lower callous/unemotional" and "lower narcissism" group, but not for the "high callous/unemotional" and "high narcissism" group (moderators). Impulsiveness was found to predict more post-treatment externalizing problems rated by adolescents (predictor), but not more post-treatment externalizing problems rated by parents., Conclusions: These findings point out the clinical relevance of adequately assessing psychopathic traits in adolescents referred for treatment of antisocial behaviour, and identifying those adolescents who show high levels of these traits. It is important to tailor MST specifically to meet the needs of juveniles with high levels of callous/unemotional traits and high levels of narcissism to obtain the same level of effectiveness as with juveniles scoring lower on these traits.

The aim of this study was to examine the effect of treatment characteristics on recidivism in a forensic youth-psychiatric outpatient clinic. The treatment offered comprised functional family therapy (FFT), individual cognitive behavioural therapy (CBT), or CBT in combination with parent training. Some of the youth additionally participated in aggression replacement training (ART). FFT and ART were implemented as a trial version, meaning that most therapists had not received formal training yet. Treatment characteristics related to recidivism were length of treatment, type of treatment, number of sessions, and the therapist. The longer the period of treatment and the greater the number of sessions, the higher the recidivism, even after controlling for risk of recidivism based on static risk factors. Juveniles who participated in ART reoffended more often than juveniles who had not participated in such training. Given the fact that FFT and ART were not well-implemented trial versions, it can be concluded that poorly implemented treatment leads to poor outcomes.

To date, there is surprisingly little research on differences in the prevalence and impact of risk factors for general recidivism between juveniles who have committed sexual offenses (JSO) and juveniles who have committed nonsexual offenses (NSO). Therefore, we examined differences in the prevalence and impact of dynamic risk factors for general delinquency between youth with nonsexual offenses (NSO, n = 504), youth with misdemeanor sexual offenders (MSO, n = 136), youth with felony sexual offenders (FSO, n = 116) and youth with offenses against much younger children (CSO, n = 373). The sample consisted of boys with a mean age of 15.3 years (SD = 1.5). The prevalence of dynamic risk factors for general delinquency was significantly lower in JSOs than in NSOs. More serious sexual offenses were associated with a lower prevalence of dynamic risk factors. In contrast, the impact of most dynamic risk factors on general recidivism proved to be significantly larger among JSOs compared to NSOs. The relative importance of the dynamic risk factors varied for each type of JSO, resulting in differences in the dynamic risk profiles of the various types of JSOs.

This study examined the influence of group climate on empathy in a Dutch youth correctional facility in a sample of 59 incarcerated delinquent boys. Higher levels of empathy have been shown to be associated with less delinquent and more prosocial behaviour and may therefore be vital for successful rehabilitation and recidivism reduction. Although empathy was originally considered to be a trait, recent neurobiological research has shown that empathy has state-like properties in that levels of empathy change in response to the social environment. This study showed that differences in group climate were associated with cognitive empathy in juvenile delinquents but not with affective empathy. It is speculated that inmates' state-depressive feelings and anxiety could diminish the effects of prison group climate on affective empathy. The discussion focuses on group dynamics in youth correctional facilities. A positive prison group climate in a youth correctional facility could turn out to be a major factor contributing to effectiveness of secure institutional treatment.

To investigate the link between attachment to parents and delinquency, and the potential moderating effects of age and sex, 74 published and unpublished manuscripts (N = 55,537 participants) were subjected to a multilevel meta-analysis. A mean small to moderate effect size was found (r = 0.18). Poor attachment to parents was significantly linked to delinquency in boys and girls. Stronger effect sizes were found for attachment to mothers than attachment to fathers. In addition, stronger effect sizes were found if the child and the parent had the same sex compared to cross-sex pairs of children and parents. Age of the participants moderated the link between attachment and delinquency: larger effect sizes were found in younger than in older participants. It can be concluded that attachment is associated with juvenile delinquency. Attachment could therefore be a target for intervention to reduce or prevent future delinquent behavior in juveniles.

The present study examines the cross-sectional and longitudinal associations between fathers' and mothers' parenting styles and male and female delinquency using a sample of 330 Dutch families with a mid or late adolescent son or daughter (ages 14-22), followed across two measurement waves with a 5-year interval. Parenting styles of fathers and mothers were linked to delinquency. A significant parenting style by sex interaction was found: neglectful parenting was related to higher levels of delinquency in males and permissive parenting was linked to delinquency in females. A long term relationship was found between fathers' neglectful parenting style and delinquency in males. Furthermore, results revealed that levels of delinquency were the lowest in families with at least one authoritative parent and highest in families with two neglectful parents, indicating that the level of delinquency was dependent on the combination of mother's and father's parenting styles., (Copyright © 2011 The Foundation for Professionals in Services for Adolescents.

This meta-analysis of 161 published and unpublished manuscripts was conducted to determine whether the association between parenting and delinquency exists and what the magnitude of this linkage is. The strongest links were found for parental monitoring, psychological control, and negative aspects of support such as rejection and hostility, accounting for up to 11% of the variance in delinquency. Several effect sizes were moderated by parent and child gender, child age, informant on parenting, and delinquency type, indicating that some parenting behaviors are more important for particular contexts or subsamples. Although both dimensions of warmth and support seem to be important, surprisingly very few studies focused on parenting styles. Furthermore, fewer than 20% of the studies focused on parenting behavior of fathers, despite the fact that the effect of poor support by fathers was larger than poor maternal support, particularly for sons. Implications for theory and parenting are discussed.

We investigated trajectories of adolescent delinquent development using data from the Pittsburgh Youth Study and examined the extent to which these different trajectories are differentially predicted by childhood parenting styles. Based on self-reported and official delinquency seriousness, covering ages 10-19, we identified five distinct delinquency trajectories differing in both level and change in seriousness over time: a nondelinquent, minor persisting, moderate desisting, serious persisting, and serious desisting trajectory. More serious delinquents tended to more frequently engage in delinquency, and to report a higher proportion of theft. Proportionally, serious persistent delinquents were the most violent of all trajectory groups. Using cluster analysis we identified three parenting styles: authoritative, authoritarian (moderately supportive), and neglectful (punishing). Controlling for demographic characteristics and childhood delinquency, neglectful parenting was more frequent in moderate desisters, serious persisters, and serious desisters, suggesting that parenting styles differentiate non- or minor delinquents from more serious delinquents.
