^†Sexual bother was measured using the EPIC sexual bother subscale; lower scores indicate greater sexual bother

^‡Relationship function models were limited to participants who reported to be married or in an equivalent relationship (n = 54). Because of the smaller subgroup sample size, covariates were limited to months of ADT and current sexual function, which were chosen based on conceptual relations with other variables in the model and to answer research questions

ADT = androgen deprivation therapy; CES-D = Center for Epidemiologic Studies Depression Scale; DAS = Dyadic Adjustment Scale; EPIC = Expanded Prostate Cancer Index Composite; FACT-G = Assessment of Cancer Therapy—General Module; QOL = quality of life
