By using the Health Action Process Approach (HAPA) model as a theoretical backdrop, the proposed study aims to provide a 10-week e-health learning strategies for Chinese cardiac patients, with which they can follow at home after rehabilitation discharge. The current study will examine whether the cardiac rehabilitation patients in intervention group would increase their physical activity (PA) level and fruit-vegetable intake (FVI), improve the social-cognitive variables of PA and FVI, and enhance mental health outcomes in comparison with control condition; and whether the social-cognitive variables would mediate the association between intervention and adopting a healthy lifestyle. The study findings may contribute to the current multiple health behaviour intervention research and support Chinese cardiac patients to maintain rehabilitation outcomes and cultivate a healthy lifestyle.
