Interviewed 150 Palestinian mothers and their children living amidst the Intifada uprising in what was then the Israeli-occupied West Bank. Found that the number of risks present in a child's life was significantly correlated with the number of behavioral problems the child exhibited. Under conditions of high accumulated risk, boys evidenced more…

This study examined whether item overlap, or measurement confounding, accounts for the correlation between temperament and behavior problem symptoms in children. Experts rated items on Children's Behavior Questionnaire and Preschool Behavior Questionnaire for their fit to both constructs, and then these items were factor analyzed with longitudinal…

Examined how peer acceptance and friendships moderated the link between family adversity and child externalizing behavioral problems. Found that peer acceptance in kindergarten and Grade 1 moderated the relationship between family adversity measures and externalizing behavior problems in Grade 2; friendship served as a moderator for harsh…

Examined academic and behavioral problems as a function of two dimensions by which rejection may vary over time: chronicity and temporal proximity. Suggests that all levels of rejection were associated with greater absenteeism from school, and more chronic and proximal experiences of rejection were associated with elevated externalizing behavior…

Examined differences between mothers of behavior-problem boys (MBPs) and mothers of average boys (MABs)in processing information in compliance situations. Found the MBPs made greater attributions of defiant intent toward the child and experienced more anger than MABs in ambiguous stimulus situations and that MBPs expected more resistance in…

Examined mothers' demands during mothers' interactions with their 1.5- to 3.5-year olds.

Used data from National Longitudinal Survey of Youth to model developmental trajectories across middle childhood. Found that individual trajectories were extremely diverse in level and sometimes in slope. Compared to girls, boys had heterogeneous slopes for math and behavior problems. Compared to boys, girls showed a significantly higher degree of…
