Optimism and prostate cancer-specific expectations predict better quality of life after robotic prostatectomy.

ABSTRACT

We examined the relations among generalized positive expectations (optimism), prostate-cancer specific expectations, and prostate cancer-related quality of life in a prospective sample of 83 men who underwent robotic assisted laparoscopic prostatectomy (RALP) for prostate cancer. Optimism was significantly associated with higher prostate cancer-specific expectations, ß = .36, p < .001. In addition, optimism and prostate cancer-specific expectations were independent prospective predictors of better scores on the following prostate cancer-related quality of life scales Sexual Intimacy and Sexual Confidence; Masculine Self-Esteem (specific expectations only), Health Worry, Cancer Control, and Informed Decision Making (ßs > .21, ps < .05). When considered simultaneously, both optimism and specific expectations contributed uniquely to better Health Worry and Cancer Control scores, optimism was a unique predictor of better Sexual Intimacy and Sexual Confidence scores, and specific expectations uniquely predicted higher scores on Informed Decision Making. Although optimism and prostate-cancer specific expectations are related, they contribute uniquely to several prostate cancer-related quality of life outcomes following RALP and may be important targets for quality of life research with this population.
