We examined posttraumatic growth (PTG) in men treated for prostate cancer and their partners 1 year after surgery. Levels of PTG in prostate cancer survivors and their partners were similar and modest. For survivors, higher levels of presurgery negative affect, and coping by using positive reframing and emotional support were associated with higher levels of PTG 1 year following surgery. For partners, PTG 1 year after the patient's surgery was higher in partners who were partnered to employed patients, were less educated, endorsed higher cancer-specific avoidance symptoms of stress at presurgery, and used positive reframing coping. Quality of life was largely unrelated to PTG in survivors or partners. Findings suggest that psychological disruption associated with the cancer experience and coping are related to PTG in prostate cancer survivors and their partners.
