Do patterns of knowledge and attitudes exist among unvaccinated seniors?

Am J Health Behav. Nov-Dec 2006;30(6):675-83. doi: 10.5555/ajhb.2006.30.6.675.


Objective: To examine patterns of knowledge and attitudes among adults aged > 65 years unvaccinated for influenza.

Methods: Surveyed Medicare beneficiaries in 5 areas; clustered unvaccinated seniors by their immunization related knowledge and attitudes.

Results: Identified 4 clusters: Potentials (45%) would receive influenza vaccine to prevent disease; Fearful Uninformeds (9%) were unsure if influenza vaccine causes illness; Doubters (27%) were unsure if vaccine is efficacious; Misinformeds (19%) believed influenza vaccine causes illness. More Potentials (75%) and Misinformeds (70%) ever received influenza vaccine than did Fearful Uninformeds (18%) and Doubters (29%).

Conclusion: Findings suggest that cluster analyses may be useful in identifying groups for targeted health messages.
