This study validates the measurements of performance of preventive practices and identifies organizational and market factors that affect variations in the preventive care practices of health maintenance organizations (HMOs). Confirmatory factor analysis was used to assess HMO performance, reflecting the rates of five preventive practice services. A structural equation model of the preventive practice performance of HMOs was evaluated. It was discovered that HMOs that employ more board-certified primary care practitioners have a higher rate of preventive care practices and that market competition and market forces do not influence the variation in HMO preventive care practices.
