Employing a multi-method approach, we investigated observed and parent-rated child behavioral inhibition (BI) and maternal reports of their own negative affectivity (NA) as predictors of young children's internalizing problems. Participants were 201 children who were siblings between 2.5 and 5.5 years of age (mean = 3.86, standard deviation =…

Most of the individual difference variance in the population is found "within" families, yet studying the processes causing this variation is difficult due to confounds between genetic and nongenetic influences. Quasi-experiments can be used to test hypotheses regarding environment exposure (e.g., timing, duration) while controlling for…

We first examined how war-related traumatic events impact on peer and sibling relations, and how the quality of these relations in turn are associated with children's mental health, indicating a mediation model. Second, we tested the moderating (protective) effects of good peer and sibling relations in attenuating the link between trauma and…

Siblings' constructive and unstructured shared activities were examined as moderators of the links between first- and second-born siblings' adjustment across a two-year period in adolescence. Siblings (N = 189 dyads) reported on their depression, peer competency, self worth during home interviews, and their time together in constructive (e.g.,…

We examined symmetries and asymmetries within family members' psychological distress and resources in general and when exposed to traumatic events in particular. PTSD [Posttraumatic Stress Disorder] and depressive symptoms indicated distress and resilient attitudes, and satisfaction with quality of life indicated resources. We also analysed…
