围绕感知行为控制概念的概念和方法上的歧义被澄清。研究表明，对行为表现的感知控制虽然由反映自我效能和可控性信念的可分离成分组成，但仍然可以被认为是分层因素模型中的单一潜在变量。自我效能感与内部控制因素、可控性与外部控制因素之间没有必然的对应关系。自我效能感和可控性既可以反映内部因素，也可以反映外部因素，它们反映其中一个或另一个的程度是一个实证问题。最后，提出了一个案例，即感知行为控制的测量需要纳入自我效能和可控性项目，这些项目经过精心选择，以确保高度的内部一致性。
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. Self-efficacy and controllability can reflect internal as well as external factors and the extent to which they reflect one or the other is an empirical question. Finally, a case is made that measures of perceived behavioral control need to incorporate self-efficacy as well as controllability items that are carefully selected to ensure high internal consistency.
