Description: An experimental study investigating the effect of immunization information and persuasive behavioral counseling on older adults' influenza and pneumococcal immunization behavior was completed. The effect of intervention on immunization knowledge, health beliefs, health status, and health service utilization was also examined.

A Solomon Four-Group design with repeated measures was utilized. The Health Belief Model served as a theoretical framework. The study was conducted from August, 1992 through December, 1993. Subjects (n = 115) were periodically evaluated during this period with written questionnaires, telephone interviews, and home interviews.

Study results indicate that intervention had a significant, positive effect on influenza and pneumococcal immunization behavior. Experimental group influenza immunization rates were 52% (1991, preintervention), 74% (1992, postintervention), and 69% (1993). Respective control group rates were 42%, 51%, and 54%. Fifty percent of experimental subjects received the pneumococcal vaccine during the study. Two percent of control subjects were immunized for pneumonia.

Intervention also had a significant, positive effect on influenza and pneumonia health belief measures including perceived susceptibility, perceived severity, perceived immunization benefits, perceived barriers to immunization, perceived control, and general health motivation. Experimental subjects demonstrated significantly higher immunization knowledge than control subjects following intervention. Approximately 63% of control subjects were unaware of the pneumococcal vaccine. The pattern of postintervention gain was different for influenza and pneumococcal beliefs and knowledge. Intervention had no significant effect on health status or health service utilization.

Subjects immunized for influenza and/or pneumonia demonstrated significantly greater immunization knowledge scores and positive health belief scores when compared to nonimmunized subjects. In general, demographic factors were not associated with immunization. However, subjects receiving the pneumococcal vaccine were significantly more likely to be male, married, Catholic, farmers, with higher economic resources. Immunized subjects demonstrated significantly greater immunization intention and prior influenza immunization behavior.

When subjects were questioned about their reasons for immunization the following were frequent responses: physician recommendation, prior immunization/habit, self-protection from disease, and convenience. Principal reasons for nonimmunization were: being healthy/not sick, being unaware of the vaccine, lack of physician recommendation, concern about vaccine side-effects, and forgetting.
