Abstract

We describe the psychosocial distress questionnaire-prostate cancer (PDQ-PC), a psychosocial screening list developed and validated specifically for prostate cancer patients. An existing screening list, the psychosocial distress questionnaire-breast cancer (PDQ-BC), was used as a starting point. Two focus groups were then implemented to investigate which items of the PDQ-BC were relevant for the PDQ-PC and which new items were needed. Validity and reliability of the questionnaire were assessed on 278 prostate cancer patients. Factor analysis showed that the 36-item PDQ-PC comprises eight subscales, for which the internal consistency ranged from α = 0.48–0.88. Moreover, moderate to high convergent validity was found.
