This study advanced knowledge regarding the demographics of a nationally representative sample of adoptive parents and their use and level of satisfaction with adoption agency services, specifically that they are functioning well both psychologically and in their marital relationships and are satisfied with the adoption agency services that are being offered and used. It also examined the contributions of (a) psychological functioning at nine months postpartum, (b) infertility experiences, (c) tangible resources, and (d) the marital relationship in predicting the psychological health of adoptive parents at 27 months postpartum. Findings revealed that the psychological health of adoptive parents at nine months was the strongest predictor of depressive and anxiety symptoms at 27 months for both adoptive mothers and fathers, with tangible resources also contributing unique variance to the prediction of fathers' depressive symptoms. Moreover, marital hostility was found to partially mediate the relationship between mothers' depressive symptoms at nine months and 27 months postpartum.
