Abstract
Background
Sleep disruption and fatigue are ubiquitous among cancer patients and are sources of stress that may compromise treatment outcomes. Previously, we showed that a cognitive behavioral stress management (CBSM) intervention reduced anxiety and other stress-related processes in women undergoing primary treatment for breast cancer.
Purpose
This study examined secondary outcomes from a CBSM intervention trial for women with early-stage breast cancer to test if CBSM would improve sleep quality and fatigue among these patients at a single site in southern Florida. CBSM-related effects have already been demonstrated for indicators of psychosocial adaptation (e.g., general and cancer-related anxiety).
Methods
Patients were randomized to CBSM (n= 120) or a 1-day psychoeducation control group (n= 120). The Pittsburgh Sleep Quality Index (PSQI) and Fatigue Symptom Inventory were completed prior to randomization and 6 and 12 months after the baseline assignment.
Results
In latent growth analyses, women in CBSM reported greater improvements in PSQI sleep quality scores than controls, although there were no significant differences between conditions on PSQI total scores. Women in CBSM also reported greater reductions in fatigue-related daytime interference than controls, though there were no significant differences in changes in fatigue intensity. Changes in sleep quality were associated with changes in fatigue.
Conclusions
Future work may consider integrating sleep and fatigue content into stress management interventions for women with early-stage breast cancer.
