Show moreStructural Magnetic Resonance Imaging studies have reported volume reductions in several brain regions implicated in social cognition and emotion recognition in juvenile antisocial populations. However, it is unclear whether these structural abnormalities are specifically related to antisocial features, or to co-occurring callous-unemotional (CU) traits. The present study employed voxel-based morphometry to assess both grey matter volume (GMV) and grey matter concentration (GMC) in a large representative at-risk sample of adolescents (n=134; mean age 17.7yr), characterized by a broad range of CU trait and conduct disorder (CD) symptom scores. There was a significant interaction between CD symptom and CU trait scores in the prediction of GMV in the anterior insula, with a significant positive association between CU traits and GMV in youth low on CD symptoms only. In addition, we found a significant unique positive association between CD symptoms and GMC in the amygdala, and unique negative associations between CU traits and GMC in the amygdala and insula. These findings are in line with accumulating evidence of distinct associations of CD symptoms and CU traits with amygdala and insula GMC in juvenile antisocial populations. Show less

Show moreYouths in compulsory residential care show a high prevalence of various mental health problems but often lack motivation to engage in therapeutic treatment. Although the self-determination-theory (SDT) and the transtheoretical model of change (TTM) offer a useful framework for treatment motivation, they do not describe which interventions therapists can use to improve treatment motivation in juveniles, nor do they focus specifically on treatment motivation in a compulsory residential care setting. This article provides an overview of opportunities to enhance adolescents' motivation for treatment in compulsory residential care. Results show that in the reviewed literature, increasing autonomy and competence has received relatively little attention compared to relatedness. In addition, results show that treatment motivation can be enhanced in several different ways, ranging from interventions on an individual to an organizational level. This may indicate that enhancing motivation for treatment in a residential setting needs intervention on multiple levels, involving youths, therapists, group workers and parents. Scientific evidence, however, is limited. Regarding the lack of studies that examine the need for autonomy and competence, future studies should focus on these basic needs for motivation. Show less

Show moreIn 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 < 0.05, reactive aggression: F = 3.7, p < 0.05). Hierarchical regression revealed that the LPE specifier uniquely explained 7 % of the variance in reactive aggression, additionally to the AoO subtyping. For proactive aggression, the interaction between AoO and the LPE added 4.5 % to the explained variance. Although the LPE specifier may help to identify a more aggressive subtype of CD in adolescents, the incremental utility seems to be limited. Therefore, clinical relevance of the LPE specifier in high-risk adolescent samples still needs to be investigated thoroughly. Show less

Show moreBackground: In Europe, the number of females exhibiting oppositional defiant disorder (ODD) and conduct disorder (CD) is growing. Many of these females live in youth welfare institutions. Consequently, there is a great need for evidence-based interventions within youth welfare settings. A recently developed approach targeting the specific needs of girls with ODD and CD in residential care is START NOW. The aim of this group-based behavioural skills training programme is to specifically enhance emotional regulation capacities to enable females with CD or ODD to appropriately deal with daily-life demands. It is intended to enhance psychosocial adjustment and well-being as well as reduce oppositional and aggressive behaviour. We present the study protocol (version 4.1; 10 February 2016) of the FemNAT-CD intervention trial titled 'Group-Based Treatment of Adolescent Female Conduct Disorders: The Central Role of Emotion Regulation'. Methods/design: The study is a prospective, confirmatory, cluster-randomised, parallel-group, multi-centre, randomised controlled trial with 128 institutionalised female adolescents who fulfil the diagnostic criteria of ODD and/or CD. Institutions/wards will be randomised either to provide the 12-week skills training as an add-on intervention or to provide treatment as usual. Once the first cycle is completed, each institution will run a second cycle with the opposite condition. Primary endpoints are the pre-post change in number of CD/ODD symptoms as assessed by a standardised, semi-structured psychiatric interview (Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime, CD/ODD section) between baseline and the end of intervention, as well as between baseline and a 3-month follow-up point. Secondary objectives include pre-post change in CD/ODD-related outcome measures, most notably emotional regulation on a behavioural and neurobiological level after completion of START NOW compared with treatment as usual. Discussion: To our knowledge, this study is the first to date to systematically investigate the effectiveness of an adapted integrative psychosocial intervention designed for female adolescents with ODD and CD in youth welfare settings. Trial registration: German Clinical Trials Register (DRKS) identifier: DRKS00007524. Registered on 18 December 2015 and with the World Health Organisation International Clinical Trials Registry Platform. Show less

Show moreLow autonomic (re)activity is a consistent correlate of antisocial behavior in juveniles. However, longitudinal research relating autonomic measures to persistent antisocial behavior has remained scarce. Therefore, in the present study we examined the predictive value of heart rate (HR) and heart rate variability (HRV, often studied as respiratory sinus arrhythmia) for reoffending in delinquent male adolescents. At initial assessment, HR and HRV were measured at rest and in response to a public speaking task. Registered reoffending was assessed after 5-year follow-up. Attenuated HR response and stronger HRV response to stress predicted higher reoffending rates. Results provide evidence that HR/HRV reactivity are neurobiological markers for persistent juvenile antisocial behavior. Although effect sizes were small to moderate, our findings underscore the consistency of the relationship between autonomic markers and antisocial behavior. Show less
