Evaluating a psychosocial intervention for men with prostate cancer and their partners: Outcomes and lessons learned from a randomized controlled trial.

AIM: This study evaluated the process and outcome of a psychosocial intervention for men with prostate cancer and their partners. As more men survive prostate cancer, they and their partners need help and support to help them cope with the physical and psychosocial effects of the disease and treatment. There is a lack of psychosocial interventions for men with prostate cancer and their partners. METHODS: A randomized controlled trial was conducted with 34 participants to measure the effects of the intervention on selected psychosocial outcomes, post-intervention and at one month' follow-up. The nine-week program (CONNECT) consisted of three group and two telephone sessions. It focused on symptom management, sexual dysfunction, uncertainty management, positive thinking and couple communication. The outcomes, measured by validated tools were: self-efficacy, quality of life, symptom distress, communication, uncertainty and illness benefits. RESULTS: The men in the intervention group did better on two outcomes (communication and support) than controls. Partners in the intervention group did better than controls on most outcomes. Less participants than expected participated in the trial. The reasons for non-participation included partners not wishing to participate, men not interested in group work, and not understanding the core purpose of the intervention. The cost of training facilitators and for delivering the intervention appeared to be low. CONCLUSION: The knowledge generated from this study will be beneficial for all those grappling with the challenges of developing, implementing and evaluating complex psychosocial interventions. This study has also highlighted the difficulties in recruiting men and their partners in clinical trials.
