Personality, treatment choice and satisfaction in patients with localized prostate cancer.
OBJECTIVE
Radical prostatectomy (RP), external beam radiation (XRT) and brachytherapy (BTX) are the most commonly used treatments for localized prostate cancer. We studied whether patient personality influences treatment choice and overall treatment satisfaction.


METHODS
From 1998 to 2002, 219 consecutive patients treated with RP (n = 74), XRT (n = 73), or BTX (n = 72) at our institution who remained free of biochemical recurrence were sent the Big Five Inventory (BFI) and a satisfaction/treatment participation questionnaire. We compared personality, satisfaction and participation scores between the three groups. Correlation between personality and satisfaction was determined. Multivariate regression was used to determine association between personality and satisfaction/participation after controlling for patient- and disease-related factors.


RESULTS
Higher mean satisfaction and participation scores were observed within the RP and XRT groups, respectively (P = NS). No significant differences in personality were observed between groups. XRT patients tended to have higher extroversion, openness and agreeability scores, while RP patients tended to be more neurotic and conscientious (all P = NS). After controlling for other factors, a negative correlation was found between openness scores and satisfaction and a positive correlation between conscientiousness scores and satisfaction. Specific personality traits were associated with interest in participation in care for both RP and BTX patients but not for XRT patients.


CONCLUSIONS
There are mild variations in personality as measured by the BFI between patients undergoing treatment for localized prostate cancer. Certain BFI-measured personality traits may be associated with levels of satisfaction following therapy. Disease concerns and provider recommendations may override the influence of personality in the decision-making process.
