Scores on a survey to measure parental hesitancy about vaccinating their children were associated with immunization status.
This is according to a study by Douglas J. Opel, M.D., M.P.H., of the University of Washington and Seattle Children's Research Institute, and colleagues.
The Parent Attitudes About Childhood Vaccines survey (PACV) was designed to identify parents who underimmunize their children. Researchers gave it to English-speaking parents of children ages 2 months old and born between July 10 and December 10, 2010, who belonged to an integrated health care delivery system in Seattle. The PACV was scored on a scale of 0 to 100, with 100 indicating high hesitancy about vaccines. Childhood immunization status was measured as the percentage of days from birth to 19 months of age that children should have been immunized but were not.
"Our results suggest that PACV scores validly predict which parents will have underimmunized children," the study concludes.
