Current research shows that grandparents have made significant contributions to at-risk families. However, few studies have examined the benefits of grandparenting in non-at-risk populations. This study considered whether emotional involvement with a grandparent is associated with prosocial behavior in adolescent grandchildren and examines the mediating role of empathy and perspective taking. A longitudinal sample of 500 participants were taken from waves two thru five of the Flourishing Families Project (FFP) and used to construct a latent growth curve model. Results indicate that emotional involvement with a grandparent was positively linked with initial levels of prosocial behavior in grandchildren. Furthermore, results indicated that empathy and perspective taking partially mediated the connection between grandparent's involvement and the initial levels of prosocial behavior in their grandchildren. Discussion focuses on the distinct contribution grandparents give to families.

Conflict is a common problem among families, and children may be negatively affected by this family dynamic. Some family characteristics may protect children from negative effects, even in the midst of conflict. Though little research has been conducted addressing familial effects of humor, the current longitudinal study examined the moderating effect of humor on the relationship between family conflict and child self regulation. Two hundred ninety six two-parent families from the Seattle area were surveyed and observed as a party of Brigham Young University's Flourishing Family Project. Family conflict and coded humor from an observation task were assessed at time 1 and self regulation in the child was assessed at both time 1 and one year later. Results indicated that (1) family conflict negatively influences child self regulation, (2) that humor between fathers and children is associated with child self regulation, and (3) that humor between fathers and children may buffer the effects of family conflict on a child's self regulation. Humor between mothers and children and between mothers and fathers did not moderate the relationship between family conflict and child self regulation. These results suggest that some forms of family humor may provide families with healthy child outcomes. Limitations and implications for family therapy are discussed.

This study examined whether the quality of the sibling relationship can alter the negative impact of stress on child well being. Participants were of 311 families (236 two parent families and 75 single parent families) with an adolescent child (M age of child at Time 1 = 11.25, SD = .99, 51% female) who took part in the Flourishing Families Project. Data were assessed using both a multiple time point cross-section and a two wave longitudinal design. Hierarchal linear regression suggested that when assessing the direct effects of sibling on well being, sibling affection is a better predictor of well being, but when assessing indirect effects, sibling conflict is a better predictor. Little evidence was found to support the idea that siblings moderate the impact of stress by buffering or decreasing the negative impact of stress. Results did indicate that sibling conflict was a salient moderator of stress in that conflict exacerbates the already negative impact of stress. Results from this study also suggest that when assessing the buffering or exacerbating impact of siblings, cross-sectional data produces better explanatory power than when these constructs are assessed longitudinally. However a single time point, cross-sectional design does not account for dynamic changes over time in either the sibling relationship, the level of stress or well being. Research designs such as multiple time, point cross-sectional studies or growth curve analyses are recommended.
