N2 - Background and Purpose: Self-efficacy, a central construct in health interventions, has been measured in various contexts. The absence of any published meta-review of self-efficacy instrumentation led to the current meta-synthesis that reports and evaluates the instrumentation processes. Methods: A systematic search resulted in 39 self-efficacy instrumentation studies, which were evaluated for the aspects of conceptual bases, health contexts, operational definition, instrumentation procedures, reliability and scale length, and item content. Results: Primarily based in Bandura's social cognitive theory, these studies reported selfefficacy instrumentation for developing new scales and modifying/validating measures for illness management, healthy behavior adoption/maintenance, disease/risk prevention, and aging management. Trait-like, specific-domain, and situation approaches were used for generating item content. Problems in some studies include non-efficacy items, a lack of systematic instrumentation procedures, item content too general for specific-domain self-efficacy, and measurement inefficiency. Conclusions: The piecemeal fashion of selfefficacy instrumentation has resulted in incomparable self-efficacy measures of similar domains of health functioning. A trans-domain framework, thus, is warranted. Suggestions are provided for solving other problems in self-efficacy instrumentation.
