Couples coping with advanced prostate cancer: an explorative study on decision-making preferences, self-efficacy and...

To date, there is a lack of understanding of the treatment/disease-related health behaviors of patients with advanced prostate cancer (PCa) and their spouses. The purpose of this study was to explore the characteristics of treatment decision-making (DM) preferences, general self-efficacy (SE) and fear of progression (FoP) among couples coping with advanced PCa.

In this explorative study, 96 patients with advanced PCa and their spouses answered the multiple choice version of the Control Preferences Scale (CPS, regarding DM), General Self-Efficacy Short Scale (ASKU, regarding SE), and short form of the Fear of Progression Questionnaire (FoP-Q-SF, regarding FoP). Corresponding questionnaires were employed for patients' spouses were evaluated, and correlations were subsequently drawn.

More than half of the patients (61%) and spouses (62%) preferred active DM. Collaborative DM was preferred by 25% of patients and 32% of spouses, and 14% of patients and 5% of spouses preferred passive DM. FoP was significantly higher among spouses than among patients (p < 0.001). The difference in SE was not significant between patients and spouses (p = 0.064). FoP and SE negatively correlated among patients (r = - 0.42; p < 0.001) and among spouses (r = - 0.46; p < 0.001). DM preference did not correlate with SE and FoP.

High FoP and low general SE are related among both patients with advanced PCa and their spouses. FoP seems to be higher among female spouses than among patients. Couples seem to be largely in agreement when it comes to playing an active role in treatment DM.
