Abstract: Perceived self-efficacy is a powerful operative construct that refers to one’s capability to master challenging tasks in the future. Its eminent role in health behavior change programs is discussed with a focus on theory, assessment, construct validity, and change.

The construct of self-efficacy has become an essential part of most health behavior theories. Moreover, the Health Action Process Approach has made a further distinction between three stages of change in which the construct operates slightly differently: pre-action task self-efficacy, coping (or maintenance) self-efficacy, and recovery self-efficacy. This process-based distinction has implications for the assessment of self-efficacy. Measurement examples will be provided that were applied in various intervention settings targeting physical activity, dietary changes, and alcohol consumption. Moreover, examples of digital interventions will be given.

Convergent and discriminant validity has been examined using multiphase-multibehavior structural equation models. Further, in terms of self-efficacy changes, it has been found frequently that scores do not improve during treatment along with behavioral improvements, and possible reasons for this phenomenon will be discussed.
