Abstract

We examined changes in coping self-efficacy (CSE) pre- and post-chemotherapy and whether these changes predicted depressive symptoms and perceived stress after chemotherapy among women breast and gynecological cancers. We further tested whether perceived helpfulness of coping strategies used during chemotherapy influenced these effects. In a longitudinal design, participants (n = 79) provided data on CSE, depressive symptoms, and perceived stress pre-chemotherapy, post-chemotherapy (~ 4 months later), and at 8 and 12-month follow-up. During chemotherapy, participants completed a one-week daily diary on use and helpfulness of coping strategies in managing side effects. CSE decreased during chemotherapy, returning to baseline levels at follow-up. Higher problem-focused CSE pre- and post-chemotherapy predicted increases in distress among women who appraised their coping strategies as low or average in helpfulness during chemotherapy; problem-focused CSE was unrelated to changes in distress at high levels of perceived helpfulness. Increases in coping self-efficacy without concomitant helpful coping strategies may be markers for poor adjustment post-chemotherapy and identify patients who could benefit from psychosocial services. Combined education and skills-based interventions to align self-efficacy beliefs with coping strategies may reduce psychological burden.

Simulation results suggest we had 64% power to detect a 2-factor structure but 99% power to detect a 1-factor structure (Wolf et al., 2013). Given the high correlations between factors, we thus compared these results to a 1-factor model. The 1-factor model demonstrated slightly worse fit, χ2(108) = 373.70, p < .01, RMSEA = 0.070, CFI = 0.954, TLI = 0.943, SRMR (between) = 0.101, SRMR (within) = 0.095, but all strategies demonstrated large and significant loadings between- (λs: 0.43-0.78) and within-persons (λs: 0.59-0.96; Table S1) in a nearly identical pattern as the 2-factor model.

However, based on reviewer feedback, we also examined helpfulness as a moderator of the indirect effect of stopping self-efficacy on changes in depression. Helpfulness did not moderate this effect (index of moderated mediation: 0.006, SE = 0.02, 95% CI [–0.03, 0.05]).
