Assessing Implicit Theories in Sexual Offending Using Indirect Measures: Feasibility, Reliability, and Incremental Validity.

This study assessed psychometric qualities of indirect measures assessing Implicit Theories (ITs) of sexual offending: Implicit Association Task (IAT), Implicit Relational Assessment Procedure (IRAP), and Relational Responding Task (RRT). For comparison reasons, aggressive behavior was also assessed. In a male sample from the general population ( = 109), we assessed each measure's (a) feasibility (mean latency, error rate, passing criteria), (b) internal consistency, (c) convergent and discriminant validity, and (d) incremental and predictive validity.

Shaping Citizenship in the Classroom: Peer Influences on Moral Disengagement, Social Goals, and a Sense of Peer Community.

Despite the important role of peers in the social process of classroom citizenship, the peer influence related to moral disengagement, social goals, and a sense of peer community remain unclear. To this end, it was examined to what extent youth become similar to their friends in moral disengagement, social goals, and a sense of peer community. Participants were 283 South Korean third to sixth graders (M = 9.

Radicalization Processes and Transitional Phases in Female and Male Detainees Residing in Dutch Terrorism Wings.

Background: Radicalization, violent extremism, and terrorism are risks to societal security. Although research on terrorism-related behaviors is increasing, thorough empirical studies are rare.

Methods: This study investigates radicalization processes and transitions in a matched sample of female and male terrorist suspects and convicts (N = 26) residing in Dutch penitentiary terrorism wings.

Understanding Violent Extremism: Identifying Motivational Classes in Male Jihadist Detainees.

An important step in understanding violent extremist behavior is to identify its underlying motivations. Insights into what drives violent extremists to their behavior may indicate what is needed to reduce existing risk factors. To this end, this study investigated violent extremist motivations in 124 male jihadi suspects and convicts residing in Dutch prison terrorism wings.

The Interplay Between Status and Affection Needs: Testing the Imbalanced Needs Theory of Aggression in Adulthood.

Status and affection are both goals related to social needs. The proposes that although aggression can be used to realize status, this strategy is detrimental for realizing affection in the same social context. Thus, to the degree that the social circles overlap in which status and affection needs are realized, it becomes more costly (in terms of affection) to achieve status via aggression.

An empirically derived hierarchical tree typology of DSM-5 pathological personality traits in adolescence.

Traditional personality disorder (PD) taxonomies have been developed for adult populations. We aimed to identify an adolescent hierarchical tree typology of PD indicators to provide classification into broad severity classes but also more fine-grained classification within those classes. A large sample of community adolescents ( = 1,940) completed a validated dimensional measure that covers a comprehensive range of pathologically formulated personality traits, the Personality Inventory for DSM-5.

Cognitive-motivational, interpersonal, and behavioral functioning in relationship to treatment and research engagement in forensic patients with ADHD.

Objectives: To provide more insight into treatment and research responsivity in offenders with attention-deficit hyperactivity disorder (ADHD).

Method: Via self-reports and patients' scores on cognitive computer tasks, it was examined whether poorer cognitive-motivational, interpersonal, and behavioral functioning were related to treatment no-shows, longer treatment time duration intervals, and no-show at the research appointment in 52 forensic outpatients with ADHD (M  = 35.3, SD = 9.

A latent profile analysis of the Psychopathic Personality Inventory in a representative sample of referred boys.

A long tradition of theoretical and empirical work has described different variants (or subtypes) of psychopathy, in an attempt to delineate similarities and differences among constellations of psychopathic traits. Research in this area has the potential to increase our understanding of the etiology of different psychopathy variants, their associated risk, and protective factors, as well as to inform the development of tailored interventions. Drawing on data from a large, representative sample of referred boys incarcerated in the United States (N = 629; Mage = 15.

Direct Aggression and the Balance between Status and Affection Goals in Adolescence.

Previous studies have shown that status goals motivate direct forms of interpersonal aggression. However, status goals have been studied mostly in isolation from affection goals. It is theorized that the means by which status and affection goals are satisfied change during adolescence, which can affect aggression.

A healthy peer status: Peer preference, not popularity, predicts lower systemic inflammation in adolescence.

In adolescence, sensitivity to peers is heightened, which makes peer experiences highly salient. Recent work suggests that these experiences may influence individuals' immune system functioning. Although there is a need to investigate which types of developmental salient social experiences affect inflammation, no studies have examined the role of peer status in inflammatory activity so far.

Disengaging from Evil: Longitudinal Associations Between the Dark Triad, Moral Disengagement, and Antisocial Behavior in Adolescence.

Previous work has identified important correlational linkages between the dark triad of personality (Machiavellianism, psychopathy, and narcissism) and antisocial behavior in adolescence. However, little is known about the longitudinal associations between these personality characteristics and antisocial behavior, and the processes underlying these linkages. We hypothesized positive bidirectional associations between the dark triad and antisocial behavior, and that increases in moral disengagement would underlie these longitudinal associations.

Treatment no-show in forensic outpatients with ADHD.

Background: 'No-show' is important in today's mental healthcare services, yet in forensic psychiatry, little is known about its relationship to general and disorder-specific patient characteristics.

Aims: The aim of this article is to determine the prevalence of no-show and any general and disorder-specific features associated with no-show in a cohort of offenders with attention deficit hyperactivity disorder registered at a specialist forensic mental health clinic.

Methods: Participants were 118 adult men with a mean age just over 32 years (SD 8.

Being Sexually Attracted to Minors: Sexual Development, Coping With Forbidden Feelings, and Relieving Sexual Arousal in Self-Identified Pedophiles.

This article aims to provide more insight into pedophilic attraction and risk and protective factors for offending in nonclinical pedophiles. Fifteen participants were interviewed about sexuality, coping, and sexual self-regulation. Many participants struggled with acknowledging pedophilic interest in early puberty and experienced psychological difficulties as a result.

The Structured Assessment of Violence Risk in Youth in a large community sample of young adult males and females: The TRAILS study.

This study examined associations between the Structured Assessment of Violence Risk in Youth (SAVRY; Borum, Bartel, & Forth, 2002) risk and protective items, identified clusters of SAVRY items, and used these clusters to predict police contact and violence. SAVRY items were assessed in a community sample of adolescent boys and girls (N = 963, 46.5% boys) via self-, parent, and teacher reports at ages 11 and 13.

Intimate partner violence perpetrators in a forensic psychiatric outpatient setting: criminal history, psychopathology, and victimization.

This study investigated criminological, psychopathological, and victimological profiles of intimate partner violence (IPV) perpetrators in a sample of 119 Dutch female and male forensic psychiatric outpatients aged 18 to 58 years. In addition, differences in criminological, psychopathological, and victimological factors between IPV perpetrators (n = 61, 51.3%) and non-intimate violence (NIV) perpetrators (n = 58, 48.

Friendship selection and influence in bullying and defending: effects of moral disengagement.

The current study examined the development of bullying and defending over a 1-year period as related to friends' influence and individual and friends' moral disengagement (i.e., self-justification mechanisms that allow one to avoid moral self-censure of transgressive actions) in children and young adolescents.

Associations Between Dysfunctional Personality Traits and Intimate Partner Violence in Perpetrators and Victims.

In the current study, the role of borderline and antisocial personality traits and psychological and physical forms of intimate partner violence were examined. Using self- and partner-reports, 30 perpetrators (28 males) and 30 victims (29 females) of partner violence, including 23 (former) couples, were interviewed. Results showed that perpetrators (i.

Effects of family cohesion and heart rate reactivity on aggressive/rule-breaking behavior and prosocial behavior in adolescence: the Tracking Adolescents' Individual Lives Survey study.

The biological sensitivity to context hypothesis posits that high physiological reactivity (i.e., increases in arousal from baseline) constitutes heightened sensitivity to environmental influences, for better or worse.

Peer influences on moral disengagement in late childhood and early adolescence.

Moral disengagement processes are cognitive self-justification processes of transgressive actions that have been hypothesized to be learned and socialized within social contexts. The current study aimed at investigating socialization of moral disengagement by friends in two developmentally different age groups, namely late childhood (age: 9-10 years; n = 133, 42.9% girls) and early adolescence (age: 11-14 years; n = 236, 40.

Longitudinal associations between depressive problems, academic performance, and social functioning in adolescent boys and girls.

Depressive problems and academic performance, social well-being, and social problems in adolescents are strongly associated. However, longitudinal and bidirectional relations between the two remain unclear, as well as the role of gender. Consequently, this study focuses on the relation between depressive problems and three types of functioning in adolescents while testing gender differences.

Heart rate and antisocial behavior: mediation and moderation by affiliation with bullies. the TRAILS Study.

Purpose: Low heart rate (HR) has been linked to antisocial behavior (ASB). However, the effect of low HR may be mediated by affiliation with bullies. We hypothesized that individuals with low HR are more likely to affiliate with bullies and in turn are influenced by these peers.

The TRacking Adolescents' Individual Lives Survey (TRAILS): design, current status, and selected findings.

Objectives: The objectives of this study were as follows: to present a concise overview of the sample, outcomes, determinants, non-response and attrition of the ongoing TRacking Adolescents' Individual Lives Survey (TRAILS), which started in 2001; to summarize a selection of recent findings on continuity, discontinuity, risk, and protective factors of mental health problems; and to document the development of psychopathology during adolescence, focusing on whether the increase of problem behavior often seen in adolescence is a general phenomenon or more prevalent in vulnerable teens, thereby giving rise to diverging developmental pathways.

Method: The first and second objectives were achieved using descriptive statistics and selective review of previous TRAILS publications; and the third objective by analyzing longitudinal data on internalizing and externalizing problems using Linear Mixed Models (LMM).

Results: The LMM analyses supported the notion of diverging pathways for rule-breaking behaviors but not for anxiety, depression, or aggression.

The association between valuing popularity and relational aggression: the moderating effects of actual popularity and physiological reactivity to exclusion.

The association between having a reputation for valuing popularity and relational aggression was assessed in a sample of 126 female children and adolescents (mean age = 12.43 years) at a 54-day residential summer camp for girls. Having a reputation for valuing popularity was positively related to relational aggression.

Physiological reactivity and different forms of aggression in girls: moderating roles of rejection sensitivity and peer rejection.

Associations between physiological reactivity to exclusion (i.e., heart rate [HRR], respiratory sinus arrhythmia [RSAR], and skin conductance [SCR]) and relational and physical aggression were assessed.

Intrinsic and extrinsic motivation in early adolescents' friendship development: friendship selection, influence, and prospective friendship quality.

Friendships are essential for adolescent social development. However, they may be pursued for varying motives, which, in turn, may predict similarity in friendships via social selection or social influence processes, and likely help to explain friendship quality. We examined the effect of early adolescents' (N = 374, 12-14 years) intrinsic and extrinsic friendship motivation on friendship selection and social influence by utilizing social network modeling.
