Purpose: To employ theoretic health decision models to determine strat
egies that may facilitate acceptance of hepatitis vaccination programs
among adolescents and their parents/guardians. Methods: The research
was conducted in a hospital-based adolescent clinic between January an
d September 1994. Eighty adolescents and 65 parents participated in a
survey that was administered to new patients. Two groups (those who ac
cepted the vaccine and those who rejected it) were compared for each v
ariable and potential predictor. Results: The majority of adolescents
and parents indicated that their clinic care provider was the initial
contact to initiate discussion about the vaccine. Significant predicto
rs for parents' acceptance of the vaccination were their perceptions o
f the vaccine's importance to the care provider and concern about the
general risk of the disease. Predictors for adolescents' acceptance of
the vaccine was their perception that their parents felt it was impor
tant and the extent to which they believed it was for ''everyone'' to
be vaccinated. Conclusions: Providers should be aware that adolescents
are influenced by their parent's opinions and that the care provider'
s endorsement of the vaccine may be a key factor in parental acceptanc
e of the vaccine. Results of this study have potential implications fo
r public health approaches to facilitate vaccine acceptance.
