The Public and Patient Engagement Evaluation Tool: forward-backwards translation and cultural adaption to Norwegian

Background Patient engagement is recommended for improving health care services, and to evaluate its organisation and impact appropriate, and rigorously evaluated outcome measures are needed. Methods Interviews (N = 12) were conducted to assess relevance of the Canadian Public and Patient Engagement Evaluation Tool (PPEET) in a Norwegian setting were performed. The tool was translated, back translated, and assessed following cognitive interviews (N = 13), according to the COSMIN checklist. Data quality was assessed in a cross-sectional survey of patient advisory board members from different rehabilitation institutions (N = 47). Results Interviews with patient board representatives confirmed the relevance of the PPEET Organisational questionnaire in a Norwegian setting and contributed five additional items. Translation and back translation of the original PPEET showed no major content differences. Differences in vocabulary and sentence structure were solved by discussion among the translators. Comments from cognitive interviews mainly related to the use of different synonyms, layout, and minor differences in semantic structure. Results of the cross-sectional survey support the data quality and construct validity of PPEET items, including 95 score comparisons where 76 (80%) were as hypothesized. Conclusions The PPEET Organisational questionnaire has been thoroughly translated and tested, and the resulting Evalueringsverktøy for Brukermedvirkning (EBNOR) has adequate levels of comprehensibility and content validity. Further testing for measurement properties is recommended, but given these results, the EBNOR should be considered for assessing patient engagement in a Norwegian health care organisational context.
