Recruitment of breast cancer survivors and their caregivers: implications for dyad research and practice.

Abstract

Breast cancer survivors' informal caregivers experience adverse health outcomes and could benefit from interventions. Studies of caregivers' participation in research, to date, have assumed heterosexuality. The aim of this study is to identify factors associated with caregiver participation among survivors with diversity in sexual orientation. We recruited breast cancer survivors into a telephone survey and asked them to invite a caregiver. Logistic regression identified factors associated with caregivers' participation. Among 297 survivors, 12 (4%) had no caregivers, 82 (28%) refused to provide caregiver information, 203 (68%) provided caregiver contact, and 167 (56%) had caregivers participate. Caregiver participation was more likely among sexual minority than heterosexual survivors (aOR: 1.89; 95% CI: 1.08, 3.32), dyads with higher cohesion, and among caregivers who were partners. Caregiver participation was less likely among survivors with lower education and higher comorbidity. Findings provide insight into recruitment of diverse dyads into cancer survivorship research that will ultimately inform intervention design.
