Abstract P6-12-07: Metastatic breast cancer collateral damage project: Associations of disease-specific concerns and experiences with psychological health, illness management, and health behaviors
2018
Rationale: Research has identified risk and protective factors that predict health and well-being in adults with breast cancer, but this work has been focused largely on women with early-stage disease. Metastatic breast cancer (MBC) patients report worse psychological health and poorer quality of life compared to those with early-stage breast cancer. We investigated whether a newly developed measure of MBC-specific concerns and experiences, the Survey of Health, Impact, Needs, and Experiences (SHINE), is associated with psychological health, illness management, and health behaviors in a sample of MBC patients . Method: SHINE includes 36 items capturing the experience of MBC, including verbatim statements from previously collected crowdsourcing data. Participants (N=515) were recruited from Dr. Susan Love Research Foundation9s Army of Women® and other advocacy organizations. Participants also completed measures of psychological health (i.e., depression, anxiety), illness management (i.e., self-efficacy for managing medications/treatments and symptoms), and health behaviors (i.e., sleep, degree of moderate physical activity). The nine SHINE subscales, along with age, marital status, financial status, children, metastatic site location(s), and current medical treatment(s), were entered as simultaneous predictors in a multivariate regression. Psychological health, illness management, and health behaviors were entered as dependent variables in separate models. Results: With demographic and medical variables controlled, MBC-specific concerns were associated significantly with depressive symptoms ( ΔR 2=.38), anxiety ( ΔR 2=.37), efficacy for medication/treatment management ( ΔR 2=.08), efficacy for symptom management ( ΔR 2=.32), sleep disruption ( ΔR 2 =.10), and physical activity ( ΔR 2=.17), with all ps p s p s p s p p ps p p p Conclusions: After controlling for demographic and medical characteristics, MBC-specific concerns were related significantly to psychological health, self-efficacy for illness management, and health behaviors. Mortality/uncertainty concerns, social isolation/withdrawal, and self-concept disruption were especially important correlates of depressive symptoms, anxiety, and MBC-related self-efficacy. Higher concern for others was related to more sleep disruption. Approaches that address these MBC-specific concerns and promote positive experiences may be beneficial for patients.
