An online stress management workbook for breast cancer.

Cognitive behavioral stress management groups have been shown to be decrease psychological symptoms and increase adaptive coping in breast cancer patients, but dissemination of this effective intervention has been challenging. The goal of the present project was to develop an online cognitive behavioral stress management intervention for early stage breast cancer survivors and evaluate its effectiveness using a 2 group × 3 time randomized, waitlist-controlled design. Intervention and waitlist control group participants were assessed at three time points: at baseline; at 10 weeks, after which only intervention participants had used the workbook; and at 20 weeks, after which both groups had used the workbook. Results indicate that at 10 weeks intervention participants showed improved self-efficacy for coping with their cancer and for regulating negative mood and lower levels of cancer-related post-traumatic symptoms as compared to the control group, suggesting that an internet stress management intervention could be effective for helping breast cancer patients increase their confidence in their ability to cope with stress.
