A systematic review of questionnaires measuring health-related empowerment.

The objective of this systematic review was to identify questionnaires that measure health-related empowerment in adults or families and demonstrated the best evidence of reliability and validity. A search of nine data bases identified 8,269 abstracts that referred to empowerment. Full article review was completed for abstracts that met the inclusion criteria or that could not be excluded with certainty (n = 124). Fifty distinct, modified, or translated questionnaires measuring empowerment were identified in 74 articles. Each was rated in terms of reliability and validity. One questionnaire had good evidence of reliability and validity, four had moderate evidence, and 45 had limited or no evidence. Limited or no evidence for reliability and validity for many questionnaires could relate in part to lack of consensus on the theoretical definition of, and indicators for measuring empowerment. We recommend that researchers use the questionnaire rated as having good evidence and that data on reliability and validity continue to be reported for other questionnaires.
