The Relationship Between Depressive Symptoms and Social Cognitive Processing in Partners of Long-Term Breast Cancer Survivors

Abstract

Purpose/Objectives: To determine 1) if depressive symptoms in partners of long-term breast cancer survivors (BCS) could be predicted by social cognitive processing theory, and 2) if partners of younger and older breast cancer survivors were differentially affected by the cancer experience. Design: A cross-sectional, descriptive study utilizing self-report questionnaires. Setting: Indiana University and 97 ECOG-ACRIN sites. Sample: Partners of breast cancer survivors (n=508) diagnosed 3-8 years prior. Methods: Secondary data mediation analyses were conducted to determine if cognitive processing mediated the relationship between social constraints and depressive symptoms. Age-related differences on all scales were tested. Main Research Variables: Depressive symptoms; secondary variables included social constraints, cognitive processing (avoidance and intrusive thoughts), and potentially confounding variables. Findings: Cognitive processing mediated the relationship between social constraints and depressive symptoms for partners (F(5,498)= 19.911, R2=.167, p<.001). Partners of young BCS reported worse outcomes on all measures than partners of older breast cancer survivors Conclusions: As predicted by the social cognitive processing theory, cognitive processing mediated the relationship between social constraints and depressive symptoms. Furthermore, partners of younger BCS fared worse on social constraints, intrusive thoughts and depressive symptoms than partners of older BCS. Implications for Nursing: Results provide support for using the social cognitive processing theory in intervention design with partners of long-term BCS to decrease depressive symptoms. Knowledge Translation: • Partners of long-term BCS report clinically significant depression. • Partners of younger BCS report higher levels of depressive symptoms than the national average and than partners of older survivors. • Addressing social constraints within the dyad may improve depressive symptoms.
