Latino patients have been shown to engage in advance care planning (ACP) at much lower rates than non-Latino White patients. Coping strategies, such as the use of emotional support, may differentially relate to engagement in ACP among Latino and non-Latino patients. The present study sought to examine the moderating effect of ethnicity on the relationship between the use of emotional support as a coping strategy and completion of advance directives.

The present study employed a weighted sample (Nw = 185) of Latino and non-Latino White patient participants in Coping with Cancer III, an National Institutes of Health–sponsored, multisite, longitudinal, observational cohort study of patients with advanced cancer and their informal caregivers and oncology providers designed to evaluate Latino/non-Latino disparities in ACP and end-of-life cancer care. Main and interaction effects of Latino ethnicity and use of emotional support on patient use of advance directives were estimated as odds ratios.

Use of emotional support was associated with dramatically lower do-not-resuscitate (DNR) order completion to a greater extent among Latino as compared to non-Latino patients (interaction AOR = 0.33, p = 0.005). Interaction effects were not statistically significant for living will or health-care proxy form completion.

Use of emotional support is associated with lower odds of completing DNRs among Latino than among non-Latino patients. Seeking and/or receiving emotional support may deter Latino patients from completing DNR orders. Research is needed to address both emotional needs and practicalities to ensure high quality end-of-life care among Latino patients with cancer.
