Psychometric Properties of the French Adaptation of the Basic Documentation for Psycho-Oncology (Po-Bado): A Distress Screening Tool.

We translated and adapted the French version of the Basic Documentation for Psycho-Oncology (Po-Bado standard version) and we report its psychometric properties. The Po-Bado is a 12-item documentation instrument that measures psychosocial burden in cancer patients (all types and stages). The intensity of a patient's psychological suffering is evaluated by a health care professional (e.g., doctor, psychologist, nurse) in a semiguided interview. Overall, 252 cancer patients (M = 57 years, SD = 12.8 years) participated, completing the Po-Bado during a supportive care consultation following initial diagnosis. Our results show good reliability of the Po-Bado scores, with high internal consistency and interrater coefficients. Low temporal stability indicated that the Po-Bado measures a state-like phenomenon (vs. trait-like). Validity analysis showed significant correlations between cancer-specific psychosocial burden and negative mood (i.e., depression, anxiety) and psychological disturbance as assessed by the General Health Questionnaire (GHQ-12). Confirmatory factor analysis validated the Po-Bado's two-factor structure (i.e., somatic and psychological burdens). A receiver operating characteristic (ROC) curve determined the optimal cutoff score of 7.5. These results suggest that the Po-Bado is an easily applicable tool for clinicians and researchers to screen effectively for psychosocial burden in oncology.
