Regret
Regret is often viewed as an emotion aimed at regulating future behavior for the better. However, selfishness may undermine this positive function and interfere with behavioral adjustment after experiencing regret. Using self-reports from a sample of adults from the general population ( N = 396; M age = 41.52, SD = 12.11; 46.5% female), it was examined to what extent egocentricity and self-interest were associated with how often people feel regre…
A Network Analysis of Social and Leisure Activities, Resilience, and Mental Health
This study investigated the network structure of various social and leisure activities, resilience, and mental health problems in a general adult sample from the Netherlands. Using a Gaussian Graphical Model, we conducted separate analyses for a range of activities in childhood and adulthood to explore timing effects. These activities were assessed in relation to internalizing and externalizing problems and two forms of resilience: psychological …
Adverse childhood experiences and different sources of resilience
Critical gaps exist in how distinct classes of adverse childhood experiences (ACEs) differ in various forms of resilience and shape mental health. This study investigated ACE classes and their differences in psychological and social-ecological resilience, ACE-related stress, and psychopathology, as well as how these forms of resilience moderate the relationship between ACE classes and psychopathology. The sample comprised 407 (71.0% female; ages …
Determinants of Rule‐Breaking in Adolescence
INTRODUCTION: Learning to navigate the many rules that regulate behavior in the adult world is a key developmental goal in adolescence. Yet, adolescents are notorious rule-breakers. In this paper, we use behavioral experiments to examine how adolescent rule-breaking is impacted by situational ambiguity and social influence. METHODS: Younger (11-15 year-olds, N = 296) and older adolescents (16-19 year-olds, N = 333) recruited from high schools in …

Trajectories of adolescents’ depressive symptoms surrounding the transition to vocational education
Although studies examined depressive symptoms across adolescence, the impact of school transitions is often neglected. This study examined trajectories of depressive symptoms surrounding the transition to vocational education. Additionally, it examined gender differences and co‐occurring trajectories of parental emotional support and adolescents’ self‐esteem. The sample comprised 840 adolescents and their parents (53% boys, 92% German, age at_T1 …

Understanding violent extremism
In recent years, the number of detainees confined for terrorism-related offenses has increased worldwide and across Europe. To understand the factors related to terrorism and its underlying motives, this study provides insights into violent extremism by assessing risk- and protective factors based on the Violent Extremism Risk Assessment-2R (VERA-2R) in 121 male jihadist residents in Dutch terrorism wings. Retrospective analyses of primary source…
Understanding Violent Extremism
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. A Latent Class Analysis resulted in three motivation profiles. The low …

Regret, Self-regulatory Abilities, and Well-Being
Emotions, like regret, have been heralded as instruments of self-regulation, by instigating reflection, learning and feedback for betterment and thus increasing well-being. Yet, this view neglects taking the frequency of regret into consideration. Frequently experiencing regret may instead be a sign of repeatedly failing to achieve betterment. Previous work has shown that people who experience regret often have lower life satisfaction. We suggest…
Understanding violent extremism
In the past decades, Europe has been shocked repeatedly by terrorist crimes. This has led to an influx of suspects and convicts of terrorism in the prison system. The aim of this study is to provide insight into socio-demographic, psychopathological and criminal background characteristics of convicted violent extremists. Retrospective analyses were conducted on primary source data from 82 convicts in Dutch prison terrorism wings. Results showed t…

Longitudinal links between identity and substance use in adolescence
Identity development has been linked to substance use, but the directionality of this relationship remains unclear. We examined the longitudinal associations of educational and relational identity with substance use across three annual waves in 360 Dutch adolescents (M age = 13.7 years). We found three latent profiles using the identity dimensions of commitment, exploration, and reconsideration as indicators. Using classification probabilities to…
The unfolding dark side
Age and gender differences across the lifespan in dark personality features could provide hints regarding these features’ functions. We measured manipulation, callous affect, and egocentricity using the Dirty Dozen and their links with agreeableness in a pooled cross-sectional dataset (N = 4292) and a longitudinal dataset (N = 325). Age trends for all dark personality features were progressive through adolescence, but negative through adulthood. …
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. This is tested in a pooled sample of (pre)adolescents ( N = 1536; 49% girls; ages 10–15), by examining associations between status goa…

Friendship selection and influence in bullying and defending
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. Via longitudinal social network analysis (RSiena), it was tested whether similarity between friends in bullying and defending developed ov…
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. Depressive problems and functioning of 2,230 children w…

Social Goals and Adolescent Friendships
This study examined adolescent friendship selection and social influence with regard to agentic (status and power) and communal (closeness and affiliation) goals at three waves during middle school ( N = 504; 12–14 years; 53% boys). Meta‐level findings across four friendship networks indicated social influence for both goal orientations: friends grew more similar to each other in agentic as well as communal goals. Moreover, in one friendship netw…
O2-3.4 Heterogeneity in disability associated with major depressive disorder
Introduction Major depressive disorder (MDD) is the leading cause of disability worldwide and its impact on patients' functioning exceeds that of chronic medical conditions. Previous studies reported that severity of depression and disability show synchrony of change. However, there are patients with severe depressive symptoms who function rather well, suggesting that certain characteristics influence the association between depression severity a…
Forms and Functions of Aggression in Adolescent Friendship Selection and Influence
Aggressive children are known to have friends. However, less is known about the impact of aggression on friendship development and how this can differ for overt and relational (i.e., the forms) and instrumental and reactive (i.e., the functions) aggression. This longitudinal study utilized the forms and functions perspective on aggression to assess social selection and influence in adolescents' (N = 337, 12–14 years) friendship networks. Instrume…
Empirical test of bullies' status goals
The literature suggests that status goals are one of the driving motivations behind bullying behavior, yet this conjecture has rarely if ever been examined empirically. This study assessed status goals in three ways, using dyadic network analysis to analyze the relations and goals among 10–11 and 14–15 year olds in 22 school classes ( N boys=225; N girls=277). As a validation bullies were contrasted with victims. Bullies had direct status goals (…
