Objective. Beliefs in one's ability to perform a task or behaviour successfully are described as self-efficacy beliefs (Bandura, 1977). Since individuals have to deal with differing demands during a behaviour-change process, they form phase-specific self-efficacy beliefs directed at these respective challenges. The present study, based on the Health Action Process Approach ...
