Low Social Well-Being in Advanced and Metastatic Prostate Cancer: Effects of a Randomized Controlled Trial of Cognitive Behavioral Stress Management

Background Social well-being impacts cancer patients’ health-related quality of life (HRQOL) and coping style. This secondary analysis was conducted to examine whether advanced prostate cancer survivors who had experienced low social well-being would benefit from a web-based cognitive behavioral stress management (CBSM) intervention. Method APC survivors ( N = 192) who had received androgen deprivation therapy (ADT) were randomized to a 10-week CBSM or a health promotion (HP) control condition. A subsample of participants ( n = 61) with low pre-intervention SWB (measured by social support from and relationship satisfaction with family and friends) was included in the study. Multilevel models compared participants’ PC-specific quality of life (sexual, hormonal, urinary), affect-based psychosocial burden (cancer-related anxiety and distress), and coping strategies at baseline, 6 months, and 12 months. Covariates were included in all models as appropriate. Results Participants randomized to the CBSM condition showed significantly greater improvements in fear of cancer recurrence and cancer-related intrusive thoughts than those in the HP control condition. A significant condition by time interaction was also found, indicating that CBSM improved participants’ PC-related fear in both short- (6 months) and long-term (12 months). However, the CBSM intervention did not significantly impact APC-related symptom burden. Only for the urinary domain, clinically meaningful changes (CBSM vs HP) were observed. In addition, all participants, regardless of condition, reported less coping (e.g., emotion-, problem- and avoidance-focused) over time. Conclusion As predicted, the CBSM intervention improved several affect-based psychosocial outcomes for APC survivors with low baseline SWB.
