Physical Activity: Feasibility Study

The PAS intervention will be a web-based intervention to address the unique barriers to physical activity in adults with obesity, based on self-efficacy theory and effective behavioral change techniques. Self-efficacy is specified as a mediating psychological variable in the conceptual model for the promotion of physical activity. Self-efficacy refers to domain-specific beliefs (e.g., job-, transport-, domestic-, leisure-related physical activity) about their ability to execute differing levels of performance given situational demands. There is a rich literature on the importance of targeting self-efficacy as a modifiable mediating variable in PA-promoting interventions. Also, the PAS intervention will consist of effective behavioral change techniques (e.g., action planning, teach to use prompts/cues, goal setting, etc.).
