Flin, R. and Burns, C. and Mearns, K. and Yule, S. and Robertson, E. (2006) Measuring safety climate in health care. Quality and Safety in Healthcare, 15. pp. 109-115. ISSN 0963-8172
A systematic literature review was undertaken to study sample and questionnaire design characteristics (source, no of items, scale type), construct validity (content validity, factor structure and internal reliability, concurrent validity), within group agreement, and level of analysis. Twelve studies were examined. There was a lack of explicit theoretical underpinning for most questionnaires and some instruments did not report standard psychometric criteria. Where this information was available, several questionnaires appeared to have limitations. More consideration should be given to psychometric factors in the design of healthcare safety climate instruments, especially as these are beginning to be used in large scale surveys across healthcare organisations.
