Perceived Behavioral Control, Self-Efficacy, etc

Perceived Behavioral Control, Self-Efficacy, Locus of Control, and the Theory of Planned Behavior1

Abstract: Conceptual and methodological ambiguities surrounding the concept of perceived behavioral
control are clarified. It is shown that perceived control over performance of a behavior,though comprised of separable components that reflect beliefs about self-efficacy and about controllability, can nevertheless be considered a unitary latent variable in a hierarchical factor model. It is further argued that there is no necessary correspondence between
self-efficacy and internal control factors, or between controllability and external control factors.
