Research shows that sibling victimization may be as detrimental to adolescent outcomes as peer victimization. However, many questions remain unanswered with regard to protective parenting factors and consequences of sibling victimization among adolescents. This study tested a mediation model in which sibling victimization, predicted by parental…

This study built on research on sibling influences to assess potential bidirectional effects of older and younger siblings' risky behaviors on one another's risky behaviors; our longitudinal design allowed us to test these effects when siblings were at about the same chronological age, at different points in time. We also tested whether the…

This investigation examines the spread of problem behaviors (substance use and delinquency) between twin siblings. A sample of 628 twins (151 male twin pairs and 163 female twin pairs) drawn from the Quebec Newborn Twin Study completed inventories describing delinquency and substance use at ages 13, 14, and 15. A 3-wave longitudinal actor-partner…

Guided by an ecological perspective, two competing models were tested to examine how sibling relationship quality directly predicted or interacted with academic support from siblings to predict Latino adolescents' academic motivation (N = 258). Gender differences were examined utilizing multiple group analysis in structural equation modeling.…

Research findings examining the adjustment of siblings of children with autism has been inconsistent, with some studies concluding that siblings are negatively impacted, while others have found no adverse effects. We argue that one reason for these inconsistent findings may be the failure by some investigators to take into account the increased…

Conditional effects of high hostile-coercive relationships and older sibling delinquency predicted younger sibling delinquency in both…

Compared attitudes, expectations, and behaviors of early adolescent girls with an adolescent childbearing sister to those of girls with nonchildbearing adolescent sisters. Found that the younger sisters of childbearing adolescents were consistently different from those of nonchildbearing adolescents on key characteristics known to be correlated…
