Conduct disorder is associated with heightened action initiation and reduced learning from punishment but not reward.

Background: Theoretical and empirical accounts of conduct disorder (CD) suggest problems with reinforcement learning as well as heightened impulsivity. These two facets can manifest in similar behaviour, such as risk-taking. Computational models that can dissociate learning from impulsively initiating actions are essential for understanding the cognitive mechanisms underlying CD.

Changes in internalizing and externalizing problems in Dutch children and adolescents receiving outpatient youth care before and during the COVID-19 pandemic.

The COVID-19 pandemic significantly impacted the mental health of children and adolescents, but its effects on treatment outcomes in youth care remain unclear. This study examines whether the pandemic influenced treatment outcomes for internalizing and externalizing problems in children receiving outpatient youth care. We analyzed data from three groups of children who received outpatient youth care (N = 1090, M = 12.

Machine learning reveals sex differences in distinguishing between conduct-disordered and neurotypical youth based on emotion processing dysfunction.

Background: Theoretical models of conduct disorder (CD) highlight that deficits in emotion recognition, learning, and regulation play a pivotal role in CD etiology. With CD being more prevalent in boys than girls, various theories aim to explain this sex difference. The "differential threshold" hypothesis suggests greater emotion dysfunction in conduct-disordered girls than boys, but previous research using conventional statistical analyses has failed to support this hypothesis.

Investigating the impact of acceptance and commitment therapy for mental healthcare professionals: the effect on patients´ self-stigmatization, a pilot study.

Background: A significant proportion of mental health care professionals (MHCPs) hold stigmatizing attitudes about their patients. When patients perceive and internalize these beliefs, self-stigmatization can increase. Acceptance and Commitment Therapy (ACT) may decrease stigmatizing attitudes by changing the 'us' versus 'them' thinking into continuum beliefs.

Using Active and Passive Smartphone Data to Enhance Adolescents' Emotional Awareness in Forensic Outpatient Setting: A Qualitative Feasibility and Usability Study.

Background: Delinquent behavior in adolescence is a prevalent issue, often associated with difficulties across multiple life domains, which in turn perpetuates negative life outcomes. While current treatment programs show partial success in improving behavioral changes and reducing recidivism, comprehensive conclusions regarding the overall efficacy of these interventions have yet to be established. In forensic outpatient settings, the discrepancy between adolescents' limited emotional awareness and the predominant emphasis on cognitive reflection, combined with low treatment adherence, may be factors that undermine treatment efficacy.

Implementing Findable, Accessible, Interoperable, Reusable (FAIR) Principles in Child and Adolescent Mental Health Research: Mixed Methods Approach.

Background: The FAIR (Findable, Accessible, Interoperable, Reusable) data principles are a guideline to improve the reusability of data. However, properly implementing these principles is challenging due to a wide range of barriers.

Objectives: To further the field of FAIR data, this study aimed to systematically identify barriers regarding implementing the FAIR principles in the area of child and adolescent mental health research, define the most challenging barriers, and provide recommendations for these barriers.

Psychometric properties of the Dutch translation of the Child Self-Report Playfulness questionnaire.

Playfulness represents the disposition to play and has important mental health benefits. Children's playfulness is mainly rated by parents, teachers or trained assessors but playfulness is not always reflected in overt behavior. Fortunately, even young children are able to provide a perspective on their playfulness, as illustrated by research with the Child Self-Report Playfulness questionnaire (CSRP).

Prospectively predicting violent and aggressive incidents in prison practice with the Risk Screener Violence (RS-V): Results from a multisite prison study.

Preventing in-prison violence and maintaining a safe environment is an important goal within prison settings. Screening for violence risk may provide a valuable addition to reach this goal. Within the Dutch prison system, the Risk Screener Violence (RS-V) has become an important new element in overall risk management.

Changes in child and adolescent mental health across the COVID-19 pandemic (2018-2023): Insights from general population and clinical samples in the Netherlands.

Background: The COVID-19 pandemic negatively affected child and adolescent mental health and at the end of the pandemic (April 2022) child mental health had not returned to pre-pandemic levels. We investigated whether this observed increase in mental health problems has continued, halted, or reversed after the end of the pandemic in children from the general population and in children in psychiatric care.

Methods: We collected parent-reported and child-reported data at two additional post-pandemic time points (November/December 2022 and March/April 2023) in children (8-18 years) from two general population samples ( = 818-1056 per measurement) and one clinical sample receiving psychiatric care ( = 320-370) and compared these with data from before the pandemic.

The Effect of 6 weeks Physical Activity on Cognitive Control and Trait Impulsivity in Multi-problem Young Adults: First Findings of an RCT-study.

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.

Mental Health Evaluation of Younger and Older Adolescents Referred to the Center of Expertise on Gender Dysphoria in Amsterdam, The Netherlands.

The present study aimed to investigate whether differences exist between younger and older presenting adolescents at the Center of Expertise on Gender Dysphoria regarding psychological functioning and autistic traits. A total of 1487 consecutively assessed adolescents between 2000 and 2018 were divided in younger presenters (age ≤ 13.9 years) and older presenters (age ≥ 14 years).

Growing Up Together in Society (GUTS): A team science effort to predict societal trajectories in adolescence and young adulthood.

Our society faces a great diversity of opportunities for youth. The 10-year Growing Up Together in Society (GUTS) program has the long-term goal to understand which combination of measures best predict societal trajectories, such as school success, mental health, well-being, and developing a sense of belonging in society. Our leading hypothesis is that self-regulation is key to how adolescents successfully navigate the demands of contemporary society.

Evaluating changes in functioning and psychological distress in visitors of the @ease youth mental health walk-in centres.

Background: Highly accessible youth initiatives worldwide aim to prevent worsening of mental health problems, but research into outcomes over time is scarce.

Aims: This study aimed to evaluate outcomes and support use in 12- to 15-year-old visitors of the @ease mental health walk-in centres, a Dutch initiative offering free counselling by trained and supervised peers.

Method: Data of 754 visitors, collected 2018-2022, included psychological distress (Clinical Outcomes in Routine Evaluation 10 (CORE-10)), social and occupational functioning (Social and Occupational Functioning Assessment Scale (SOFAS)), school absenteeism and support use, analysed with change indicators (first to last visit), and mixed models (first three visits).

The Risk Screener Violence (RS-V): retrospective prediction of violent and aggressive incidents within the prison setting.

Introduction: Physical and verbal violence toward staff or other detained individuals is a reoccurring problem within correctional facilities. Screening for violence risk within the prison setting could provide a valuable first step in the prevention of institutional violence. The brief and compact Risk Screener Violence (RS-V) has shown to be an efficient new method for assessing concerns regarding post-release violent offending for incarcerated persons.

The Effects of a Digital, Transdiagnostic, Clinically and Peer-Moderated Treatment Platform for Young People With Emerging Mental Health Complaints: Repeated Measures Within-Subjects Study.

Background: To address the growing prevalence of youth mental health problems, early intervention is crucial to minimize individual, societal, and economic impacts. Indicative prevention aims to target emerging mental health complaints before the onset of a full-blown disorder. When intervening at this early stage, individuals are more responsive to treatment, resulting in cost-effective outcomes.

The association between delinquent peer affiliation and disruptive behavior interacts with functional brain correlates of reward sensitivity: a biosocial interaction study in adolescent delinquents.

Background: Affiliating with delinquent peers may stimulate the development of antisocial behavior, especially for adolescents who are sensitive to social rewards. The current study examines whether the association between delinquent peer affiliation (DPA) and disruptive behavior interacts with functional brain correlates of reward sensitivity in early onset male adolescents delinquents.
