Objective: This study measured the independent contributions of self-effica
cy, outcome expectations, and dental health value in predicting an objectiv
e measure of preventive oral hygiene behavior, dental plaque, Methods: One
hundred forty-eight subjects completed study measures and then had their de
ntal plaque levels measured, Results: Structural equation modeling revealed
that self-efficacy for flossing significantly predicted plaque levels but
self-efficacy for brushing, outcome expectations, and dental value did not.
Conclusion: Results supported Bandura's belief that self-efficacy for spec
ific behavior can predict outcomes of that behavior, and outcome expectatio
ns and value beliefs do not play an independent role in explaining behavior
