Albert Bandura (1977) pioneered the concept of self-efficacy as a “unifying theory of behavioral change” (p. 91) and based on the state of behavioral theory nearly 50 years later he did not overstate his case. Self-efficacy has become a key component of nearly every theory of behavior change used by social scientists, including the theory of planned behavior (Ajzen, 1991), protection motivation theory (Maddux & Rogers, 1983), the health belief model (Rosenstock, Strecher, & Becker, 1988), and the extended parallel process model (Witte, 1992). It might be said that no other single concept has had such an impact on predicting and promoting behavioral change through communication messages as self-efficacy. Self-efficacy is defined as a person’s perceived ability to execute a specific behavior in a specific situation, and should not be misconstrued as a general trait or personality characteristic (Strecher, DeVellis, Becker, & Rosenstock, 1986).
