This document summarizes a study that aimed to predict factors influencing stretching exercise behavior among office employees based on Pender's Health Promotion Model. The study used questionnaires to assess interpersonal influences, situational influences, and stretching exercise behavior in 420 office employees. Results showed a significant relationship between interpersonal influence and stretching exercise, but not between situational influence and stretching exercise. Interpersonal influences were found to strongly predict stretching exercise behavior. Therefore, the study concluded that interpersonal factors could be an important principle for health education programs to promote stretching exercise behavior according to Pender's model.
