Background: Increasing self-efficacy is an effective method to increase physical activity. Despite this, there are no systematic reviews which identify the most effective techniques to increase self-efficacy in physical activity interventions by examining how they are associated with self-efficacy changes. This meta-analysis aims to fill this gap by systematically gathering intervention studies which aimed to increase self-efficacy for physical activity. Methods: A search of three electronic databases identified 27 distinct lifestyle and recreational physical activity intervention studies.

Findings: The most frequent intervention techniques utilised were mastery experience, self-monitoring, persuasion and goal setting.
