RESUMEN
BACKGROUND AND PURPOSE: The purpose of the study was to evaluate the reliability and construct validity of the Complexity Compression Questionnaire (CCQ), a 28-item instrument designed to explain nurses' experiences when assuming multiple responsibilities in a compressed time frame. METHODS: Data were obtained from 607 registered nurses in an academic medical center in the midwestern United States who participated in a larger study on system-wide organizational change involving upgrading electronic health records. RESULTS: Cronbach's alpha for the 26-item CCQ, was .91. Exploratory factor analysis supported a 5-factor solution that explained 53.6% of the variance. CONCLUSIONS: The CCQ may be a useful tool for measurement of the effects of organizational change on the complexity of the work of nurses.
