OBJECTIVE: To better understand differences among parents in their attitudes, beliefs, and behaviors regarding childhood immunizations and health-related issues. METHODS: Forty-four survey variables assessing attitudes and beliefs about immunizations and health were analyzed. The K-means clusters technique was used to identify homogeneous groups of parents based upon their responses to the questions. RESULTS: Five clusters were identified: Immunization Advocates (33.0%), Go Along to Get Alongs (26.4%), Health Advocates (24.8%), Fencesitters (13.2%), and Worrieds (2.6%). CONCLUSIONS: Although only a small percentage of parents are seriously concerned, other parents who are generally supportive of immunizations for their child are also affected by immunization safety issues.
