Destructive conflict within the marital relationship has been shown to negatively impact the family system. Exposure to destructive interparental conflict may be particularly detrimental to adolescent development. Destructive interparental conflict is associated with decreased quality of parent–adolescent communication. One potential explanatory mechanism for this relationship is adolescents’ emotional insecurity in the interparental relationship. Exposure to destructive interparental conflict may decrease adolescents’ sense of emotional security. Therefore, this study examined whether emotional insecurity security mediated the relationship between destructive interparental conflict and parent–adolescent communication, based on a longitudinal study on family communication ( N = 225). Path analysis revealed that the relationship between destructive interparental conflict and father–adolescent communication, as well as mother–adolescent communication, was mediated by emotional insecurity. The results provide insight into the consequences that destructive interparental conflict may have for aspects of the parent–adolescent relationship, as well as practical implications for the development of future intervention programs.

The family communication project was a randomized preventive intervention designed to support families by improving interparental conflict behavior and the parent-child relationship, with the ultimate goal of decreasing emotional insecurity in the interparental relationship. Evidence for programs that may benefit father-adolescent attachment and adolescents' emotional insecurity in the marital context is a gap in the literature. According to the fathering vulnerability hypothesis, father-child attachment security might be expected to especially benefit from improvements in interparental conflict behavior. The present study evaluated whether there were any indirect effects of this intervention on emotional insecurity via attachment with each parent, with a particular interest in the role of father-child attachment. Cross-lagged panel models revealed that the parent-adolescent (PA) treatment condition predicted significantly decreased emotional insecurity at 6 months through posttest attachment to fathers, relative to the control and parent-only conditions. Mother-adolescent attachment was improved in the PA condition at posttest but was not a significant mediator of subsequent adolescent emotional insecurity. Thus, the intervention's effects on father-adolescent attachment plays an important role in explaining the long-term effects of the intervention on emotional insecurity about the interparental relationship. Results also call attention to the value of including adolescents in interventions to improve interparental conflict and parent-child relationships.

Parent-Child Interactions (PCI) is a home visit parenting intervention designed to promote positive parenting and deter punitive approaches to child behavior management. With attention to the importance of providing efficacious interventions for families from diverse backgrounds, this study used a subsample from a larger randomized controlled trial (RCT) to examine the efficacy of PCI intervention among Latinx participants. PCI was offered to 170 at-risk Latinx mother-child dyads, of whom the majority were primarily Spanish speaking. Dyads were randomly assigned to an intervention or a wait-list control condition. Path analysis modeling was used to examine parenting outcomes as a mediator of program efficacy between group assignment and children's long-term functioning. Results suggest that Latinx parent and child functioning benefited from PCI intervention 6 months following intervention. Specifically, model results indicated significant indirect effects of the PCI intervention on (1) cooperative child behavior and (2) children's externalizing behaviors 6-months posttreatment via parenting at post test, with mother-child dyads assigned to the treatment condition, relative to the control, demonstrating better functioning 6-months posttreatment. Overall, findings contribute to increased understanding of parenting intervention implementation among Latinx families.Recommendations for future study are discussed.
