Decisional conflict (DC) is a psychological construct that an individual experiences in making a decision that involves risk, loss, regret, or challenges to one’s values. This study assessed DC in a cohort of South African men undergoing curative treatment for localised prostate cancer (LPC). The objectives were to (1) to examine the association between DC and prostate cancer knowledge (PCK), demographics, state anxiety, prostate cancer anxiety and time to treatment and (2) to compare levels of DC between treatment groups [prostatectomy (RP) and external beam radiation (RT)]. Method: Data, comprising the Decisional Conflict Scale (DCS), Prostate Cancer Knowledge (PCK), State-Trait Anxiety Inventory (STAI-S), the Memorial Anxiety Scale for Prostate Cancer (MAX-PC) and demographic data from 83 participants of a larger prospective longitudinal observational study examining depression, anxiety and health related quality of life (DAHCaP) were analysed. Results: The mean age of participants was 63 years (RP 61yrs and RT 65yrs; p< 0.001). Most were of mixed ancestry (72.3%). The total DCS scores between the treatment groups (RP 25.00 and RT 18.75; p = 0.037) and two DCS sub-scores-uncertainty (p = 0.033), and support (p = 0.048), were significantly higher in the RP group. A statistically significant negative correlation was observed between state anxiety and time between diagnosis and treatment in the RP group (Spearman’s rho = 0.368; p = 0.030). There was no correlation between the DCS score and PCK within each treatment group (Spearman’s rho RP = 0.249 and RT = 0.001). Conclusion: Decisional conflict was higher in men undergoing RP. Men were more anxious in the RP group regarding the time treatment was received from diagnosis. No correlation was observed between DC and PCK. Pre-surgical management of DC should include shared decision making (SDM) which is cognisant of patients’ values facilitated by a customised decision aid.
