Predictors of dyadic planning of pelvic floor exercise: perspectives of prostate cancer survivors and partners

Abstract

Background: Dyadic planning refers to joint planning of a target person’s behavior with the support of a partner. To date, studies have not yet focused on predictors of dyadic planning. By applying findings from literature on social support provision, we aimed to explore four predictor domains in the context of prostate cancer patients’ dyadic planning of pelvic floor exercise (PFE) following radical prostatectomy. Methods: Data from 175 prostate cancer patients and their partners were analyzed in a study with 4 post-surgery assessments, each 2 months apart. PFE-related dyadic planning, burden by incontinence, affective states, and relationship satisfaction were assessed from patients and partners. PFE-related intention, self-efficacy, and individual planning were measured using patient reports. Findings: Findings from two-level models indicate that situational (burden due to incontinence), target person (positive affect, self-efficacy, and individual planning), and relationship factors (relationship satisfaction) were relevant predictors for dyadic planning. Planning partner factors played a minor role. Discussion: Results of predictor domains are in line with other findings on social support provision. Further studies should examine dyadic planning’s predictors in other health contexts.
