We took advantage of longitudinal data from families who participated in intensive in-home interviews that afforded tests of the DST and vantage sensitivity hypotheses. We tested a model that included both positive and negative parental assessments of their own relationship with their partner to capture interparental of conflict and positivity. We hypothesized that the presence of these factors will affect adolescents’ perception of their parents’ relationship (Harold et al., 1997; Harold & Conger, 1997). We expected conflict and positivity within the parent couple to be related to higher adolescent conflict perception and lower positivity perception. Similarly, we expected that couple positivity will be related to lower adolescent conflict perception and higher positivity perceptions.
