The Effect of Positive Thinking Skills Training and Acceptance and Commitment Therapy on Perceived Stress among Women with Breast Cancer

Background: Women with breast cancer may suffer from numerous psychological, physical, cognitive, and socio-emotional problems. If their psychological disorders persist, they may perceive a high level of stress. We conducted the present study to evaluate the effect of positive thinking skills training and acceptance and commitment therapy (ACT) on perceived stress among women with breast cancer in Ahvaz, Iran in 2019. Methods: This was an experimental controlled pretest-posttest study. A sample of 45 women with breast cancer was conveniently selected and randomly allocated to the positive skills training group, ACT group, and the control group. The first and second experimental groups underwent eight sessions (90-minute sessions per week) of positive thinking skills training and ACT, respectively. The research instrument included the Perceived Stress Scale. One-way analysis of covariance was used to analyze the data. Results: The mean±SD of the post-test scores of perceived stress in the positive thinking skills training group was 17.01±2.32 while it was 22.53±1.45 in the ACT group, which was significantly different from the control group (54.10±4.37). Positive thinking skills training and ACT both reduced the perceived stress in women with breast cancer in the experimental groups compared to that in the control group. Positive thinking skills training had a significantly greater effect than ACT on mitigating perceived stress (P 0.001). Conclusion: According to the results, positive thinking training and ACT were effective in reducing perceived stress in women with breast cancer. Moreover, positive thinking training was more effective in declining stress in women with breast cancer.
