Abstract：
Objective Breast cancer has become the most prevalent cancer worldwide. Breast cancer leads to both physical symptom burden and psychological distress, such as depression, anxiety and other psychological disorders. Although current literature has demonstrated the effect of physical activity in improving psychological health among cancer survivors, the underlying psychosocial mechanism is relatively understudied. This present study investigated the relationship between walking activity and emotional health among breast cancer patients, and examined the potential mediating effects of different dimensions of posttraumatic growth (PTG). Methods The level of walking activity, posttraumatic growth, and positive and negative emotions were assessed using a cross-sectional questionnaire among breast cancer patients (n=235) in the community of Pengpu Xin Cun community in Shanghai. Path analysis was used to test the hypothesized mediation model. Results The parallel mediation model indicated good fit, χ2(20)=28.11, P=0.11, CFI=0.99, TLI=0.98, RMSEA=0.04, PRMSEA<0.05=0.61. Walking activity promoted positive emotions in breast cancer patients by facilitating the personal strength dimension of PTG, the standardized indirect effect was 0.07 (95% CI [0.02, 0.13]); walking activity reduces negative emotions through improving appreciation of life dimension of PTG, the standardized indirect effect was -0.13(95%CI[-0.21,-0.05]). Conclusions PTG plays an important mediating role in the effect of walking activity on the emotional health of breast cancer patients. Clinical practice and supportive care should consider providing guidance of physical activity, combined with psychosocial interventions targeting PTG to improve patients’ emotional health.
