Antenatal maternal mental health status not only predicts postpartum mental status, but also influences family health. In Asia, however, little scientific research has been conducted on antenatal parenting intervention to date, nor has there been much emphasis on fathers in considerations of parenting support. Building upon our past research achievements that showed a strong need for parenting support focusing on the mental health aspect in Japan and Vietnam, we report on the process of adapting an Australian antenatal group-based psychosocial intervention involving fathers into Japanese and Vietnamese public service settings. The intervention was feasible at given sites and well accepted among volunteer couples. The presented processes to ease adaptation may be useful to other health professionals in Asian regions undertaking similar initiatives. (Contains 3 tables.)
