This multimethod, prospective study examined the nature of pathways between interparental hostility and withdrawal, parental emotional unavailability, and subsequent changes in children's internalizing and externalizing behaviors, and school adjustment difficulties over a 3-year period in a sample of 210 mothers, fathers, and 6-year-old children. The results of autoregressive structural equation models indicated that interparental withdrawal had a detrimental impact on all areas of children's adjustment, whereas interparental hostility had an indirect effect on subsequent changes in child adjustment. An intermediary role of parental emotional unavailability in links between interparental withdrawal and hostility and child outcomes was indicated, with specific, differential effects observed for fathers and mothers.
