Background: Follow-up support increases the effectiveness of physical activity interventions. This study evaluates the effectiveness of 2 support modes on physical activity and mental health.
Methods: University employees were randomly assigned to a coaching program with 4 face-to-face (N = 33) or telephone-based (N = 33) support contacts. Both programs included an initial face-to-face intake session and an informational brochure. Physical activity, trait anxiety, self-efficacy, and social support were measured by self-report before and after the interventions that lasted 3 months.
Results: Both groups increased leisure-time physical activity, self-efficacy, and social support and decreased sitting time and trait anxiety. The only significant time by group interaction was found for active transportation. More specifically, participants in the face-to-face group reported a significant increase in their active transportation from pretest to posttest, whereas participants in the telephone group reported no significant change.
Conclusions: Both face-to-face support and telephone support proved to be effective in increasing the physical activity level and mental health of university employees.
