Assessing transcultural validity of the transtheoretical model with Chinese Americans and physical activity

Transtheoretical model has shown promise in promoting adoption and maintenance of physical activity and was used to guide this study. A cross-sectional design with snowball sampling was applied to recruit 201 Chinese Americans. Self-efficacy scores were significantly higher for participants in maintenance than those in precontemplation. There were no significant differences in perceived benefits and barriers in different stages. The transtheoretical model partially applied to the participants for whom the reinforcement of self-efficacy is more important than emphasizing the benefits or decreasing the barriers to regular physical activity. Cultural issues may play a critical role and should be further investigated.
