Factor structure and construct validity of a hospital survey on patient safety culture using exploratory factor analysis.
AHRQ's Hospital Survey on Patient Safety Culture (SOPS) is widely used to measure hospital staff's opinion on safety culture in their organization. Exploratory factor analysis was conducted with SOPS data to compare with the six components of Patient Safety Culture Theoretical Framework. Construct validity was good, but the authors recommend creating a supplemental survey on deference to expertise and resilience.
