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