Current theories of loneliness posit that biases in social information processing play a key role in the development and maintenance of loneliness. However, this assumption has rarely been tested in longitudinal research in adolescence. The current study concentrated on two constructs associated with such biases, that is, fear of negative…

Callous-unemotional (CU) traits predict behavioral problems in adolescence. But little is known about early modulatory factors. Behavioral Inhibition (BI) in particular has been suggested to protect against the development of CU-traits. This temperamental predisposition is characterized by heightened environmental sensitivity. The current…

Though it is well-established that self-esteem develops from childhood well into old age, little is known about the processes that influence this change, especially among young populations. This international, cross-sequential study examined the development of self-esteem in 1599 second-graders (Age M[subscript T1] = 7.99, SD[subscript T1] = 0.52…

The emotional availability scales (EAS), 4th edition, are widely used in research and clinical practice to assess the quality of parent-child interaction. This study examined the short-term reliability and continuity of the EAS (4th ed.) assessed in two similar observational contexts over a one-week interval. Sixty-two Dutch parents (85% mothers)…

This longitudinal study focused on clarifying the direction of effects between social anxiety and victimization in a community-based sample. In addition, we studied the moderating effect of gender on this association. A total of 1,649 children (45% boys, approximately 12 years old) of 65 secondary-school classes participated in the study.…

Successful emotion regulation (ER) is a central aspect of psychosocial functioning and mental health and is thought to improve and be refined in adolescence. Past research on ER has mainly focused on one-time measurements of habitual ER. Linking regulatory strategies to emotions in daily lives is key to understanding adolescents' emotional lives.…

Little is known about the development of children's lying. The present study examined whether observed social and non-social fear in preschoolers predicts children's consistent cheating (N = 460; M = 4.3 years of age) and consistent lying about cheating. When left alone, 155 (34%) children cheated in both games conducted. Of these consistently…

Sharing is an important indicator of internalised prosocial values. We examined predictors of sharing of 302 preschoolers with their younger siblings in a one-year longitudinal study. Sharing was observed during different home visits, once with father and once with mother. We examined the following predictors: both children's externalising…

Contemporary research adopts an evolutionary theoretical perspective in which bullying is strategic behavior that is conducive to peer-group status enhancement. Within this view, a high social status (i.e., popularity) has been associated with bullying others, while a high affiliative status (i.e., preference) has been associated with defending…

This study investigated perceptions of love across the lifespan using Sternberg's triangular theory of love, which distinguishes between passion, intimacy, and commitment. The study aimed to (a) investigate the psychometric properties of the short Triangular Love Scale (TLS-short) in adolescents and adults (see Appendix), and (b) track age and…

The current study examined emerging adults' gender identity and its link with several gender-related and social outcomes, by using a novel dual-identity approach that was originally developed in children. Dutch emerging adults between 18 and 25 years old (N = 318, M[subscript age] = 21.73, SD = 2.02; 51% female) indicated their similarity to the…

High and stable levels of aggression and the presence of aggressive behaviour in multiple settings according to different informants are risk factors for later problems. However, these two factors have not been investigated in early childhood. The present study investigates trajectories of parent-reported child aggression from 1.5 up to 6 years of…

Children's peer relationships are frequently assessed with peer nominations. An important methodological issue is whether to collect unlimited or limited nominations. Some researchers have argued that the psychometric differences between both methods are negligible, while others have claimed that one is superior over the other. The current study…

Difficulties in peer acceptance during elementary school have been associated with emotional and behavioural problems. This study used a randomized controlled intervention design to test whether improvements in peer acceptance mediated reduced rates of emotional and behavioural problems in intervention compared to control-group children. A total…

The moderating effects of three specific conditions (status hierarchy, attractiveness hierarchy and sex ratio) on the link between status (popularity) and physical and relational aggression were examined in a large sample of adolescent boys ("N" = 1,665) and girls ("N" = 1,637) ("M" age = 13.60). In line with the…
