Using a cross-lagged effect model with 3 waves of data from a 6-year longitudinal study with 3-year intervals, transactional relations between parental marital distress and adolescent emotional adjustment were examined. The sample consisted of 531 parent-adolescent dyads. Results showed that marital distress as reported by parents and emotional adjustment as reported by adolescents were reciprocally related in a transactional model over time. This was principally true for girls and for late adolescents and young adults. For older adolescent girls, an almost full transactional model was found, whereas associations between marital distress and emotional adjustment were less strong for younger girls and were absent for boys.
