Fifty-three percent of eligible couples approached agreed to participate in CRE and of these 80% had not previously accessed CRE. Couples were a broad representative of Australian couples having their first child, but minority couples were underrepresented. A third of couples had three or more risk factors for future relationship distress (e.g., cohabiting, interpartner violence, elevated psychological distress, unplanned pregnancy). Low education was the only risk factor that predicted drop out. The transition to parenthood is a window of opportunity to recruit certain types of high-risk couples to CRE.
