Abstract

Prostate cancer treatment presents multiple challenges that can negatively affect health-related quality of life (HrQoL), and which may be further compromised by maladaptive personality styles and psychological adjustment difficulties. This study examined the utility of a comprehensive psychosocial screening tool to identify psychosocial traits that prospectively predict HrQoL status among men treated for localized prostate cancer. The Millon Behavioral Medicine Diagnostic (MBMD) was administered to 66 men (mean age 68 years, 59% Caucasian) treated by either radical prostatectomy or radiotherapy along with standard measures of general and prostate cancer-specific quality of life assessed at a 12-month follow-up. Higher scores on both summary MBMD Management Guides (Adjustment Difficulties and Psych Referral) and higher scores on personality styles characterized by avoidance, dependency, depression, passive aggressiveness and self-denigration predicted lower HrQoL (β range = −.21 to −.50). Additionally, higher scores on the MBMD Depression, Tension-Anxiety and Future Pessimism scales predicted lower HrQoL. Finally, higher scores on the MBMD Intervention Fragility and Utilization Excess scale, also consistently predicted poorer mental and physical health functioning over time. These results point to the utility of the MBMD to help screen for potential impairments in mental and physical health functioning in men undergoing treatment for prostate cancer.
