Abstract
INTRODUCTION: Few couple-focused interventions have been developed to improve distress and relationship outcomes among men diagnosed with localized prostate cancer and their partners. AIMS: We examined the effects of a five-session Intimacy-Enhancing Therapy (IET) vs. Usual Care (UC) on the psychological and relationship functioning of men diagnosed with localized prostate cancer and their partners. Pre-intervention levels of psychological and relationship functioning were evaluated as moderators of intervention effects. METHODS: Seventy-one survivors and their partners completed a baseline survey and were subsequently randomly assigned to receive five sessions of IET or UC (no treatment). Eight weeks after the baseline assessment, a follow-up survey was administered to survivor and partner. MAIN OUTCOME MEASURES: Distress, well-being, relationship satisfaction, relationship intimacy, and communication were investigated as the main outcomes. RESULTS: IET effects were largely moderated by pre-intervention psychosocial and relationship factors. Those survivors who had higher levels of cancer concerns at pretreatment had significantly reduced concerns following IET. Similar moderating effects for pre-intervention levels were reported for the effects of IET on self-disclosure, perceived partner disclosure, and perceived partner responsiveness. Among partners beginning the intervention with higher cancer-specific distress, lower marital satisfaction, lower intimacy, and poorer communication, IET improved these outcomes. CONCLUSIONS: IET had a marginally significant main effect upon survivor well-being but was effective among couples with fewer personal and relationship resources. Subsequent research is needed to replicate these findings with a larger sample and a longer follow-up.
