Trinh, Linda2007-12-192007-12-1920072007-12-19http://hdl.handle.net/1828/282Purpose: To explore the relationship between social support and adherence to a peer-based program among adolescent girls using the Theory of Planned Behaviour (TPB), and to explore barriers and facilitators related to physical activity. Methods: Participants (N=13) completed self-reported measures of social support, TPB constructs, adherence to the program, and physical activity behaviour. A one-month follow-up was conducted on all baseline measures. Open-ended questions were used to determine facilitators and barriers to physical activity. Results: At baseline, social support was a significant correlate of subjective norm (r=0.58, p<.05). At post-program, frequency of attending the program with friends (r=0.97, p<.01) was a significant correlate of attendance in the program. Also, social support was a significant correlate of PBC at post-program (r=-0.82, p<.01). Conclusions: A physical activity program targeting peer social support may serve as a viable mechanism for increasing physical activity levels in adolescent girls.enAvailable to the World Wide WebTheory of Planned BehaviourPhysical ActivityUVic Subject Index::Humanities and Social Sciences::Education::KinesiologyThesis
