Tests of indirect effects and differences by genotype are provided in Table 2. We constrained pathway sets across groups to assess genotype differences. Although positivity was not directly associated with threat appraisals among 7− adolescents, the indirect path (couple positivity → adolescent perception of interparental conflict → threat appraisal) was statistically significant (i.e., indirect path 4 in Table 2). A similar indirect association from couple conflict to threat appraisal was also found (see indirect path 1). In addition, the four-step pathway—couple conflict/positivity → adolescent perceived interparental conflict → threat appraisals → internalizing problems—was also significant for 7− adolescents (indirect paths 8 and 11). These results suggest that for 7− adolescents both couple conflict and positivity prospectively affect threat appraisals and internalizing problems. Nonetheless, couple relationships affect threat appraisals among 7− adolescents with primarily through perceived conflict. Although not different across genotypes, among 7− adolescents, the adolescent perceived interparental conflict → threat appraisals → internalizing problems path was significant (indirect path 5), as well was the couple conflict → threat appraisals → internalizing problems path (indirect path 7).
