Logotherapy-Based Online Education to Improve Physical Activity in Sedentary Workers

Insufficient physical activity (PA) among individuals with sedentary occupations is associated with an increased risk of chronic disease and reduced health-related quality of life. This study aims to evaluate the effectiveness of an originally developed logotherapy-based distance education program on physical activity, sedentary behavior, and selected aspects of health-related quality of life. A minimum of 200 participants aged 35-60 years with sedentary occupations will be recruited from multiple organizations in Croatia and randomly assigned to an experimental or control group. All participants will complete validated questionnaires assessing physical activity, sedentary behavior, health-related quality of life, self-efficacy, meaning in life, and motivation for exercise at baseline and after the intervention period. The experimental group will participate in an eight-week online education program consisting of weekly 30-minute sessions followed by brief discussions, while the control group will continue their usual lifestyle without intervention. The intervention integrates principles of logotherapy and existential analysis with the Transtheoretical Model of Behavior Change and the CALO-RE behavior change taxonomy. The findings may contribute to the development of more effective, meaning-centered approaches to promoting physical activity and reducing sedentary behavior in adult populations.
