Highlights

  • Po-Bado helps health care professionals structure their postdiagnosis consultations with cancer patients.

  • Po-Bado can be used to better identify patients’ psychological experience and needs.

  • Po-Bado can better orient patients toward appropriate supportive care.

  • Po-Bado offers good reliability and shows correlation between cancer-specific psychosocial burden and negative mood.

Abstract

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 (Mage = 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.

Development of the French adaptation of the Po-Bado

We followed the guidelines for test translation and cross-cultural validation provided by Van de Vijver and Hambleton (1996; see also the International Commission Test (ITC) guidelines on adapting tests at www.intestcom.org). The French adaptation of the Po-Bado was developed via a translation and back-translation procedure. The corresponding author, a native German-speaking psychologist, completed the first French translation and a second professional (certified) translator completed the back

Descriptive statistics

Means and standard deviations of the scores on the different measures used in this study are reported in Table 2. Gender difference tests revealed that women scored significantly higher than men on the Po-Bado, F(1, 250) = 5.92, p = .016, η2 = .02; the GHQ, F(1, 250) = 8.24, p = .004, η2 = .03; and the HADS Depression scale, F(1, 250) = 8.32, p = .004, η2 = .03. There were no gender differences on the HADS Anxiety subscale.

Reliability and item analysis

The coefficient α value was .87 for the Po-Bado scores. As indicated in

Discussion

The current study is the first to evaluate the psychometric properties of the French version of the Po-Bado, a face-to-face interview tool, developed to assess the specific psychosocial burden of cancer. Overall, the results support the validity and reliability of this scale in a French sample of patients with various stages and types of cancer.

Because it is important to offer evidence about the latent trait(s) or factor(s) that underlie each observed score, the correlated two-factor model of

Conclusions

Herschbach et al. (2008) have shown that this tool is well adapted to acute situations as well as to long-term follow-up, in a hospital or clinic setting. The psychometric and clinical screening ability of the Po-Bado, as well as the supportive care relationship that it favors can be of considerable benefit for teams faced with cancer patients’ psychological suffering throughout all stages of the illness. On a more general level, the Po-Bado approach is in line with the overall objective of
