Currently available measures of self-efficacy described in educational and psychological research literature were cataloged and reviewed after a literature search. To identify and locate these measures, searches of "Psychological Abstracts" and the ERIC system were conducted using self-efficacy and related keywords. Results of the searches, summarized in Table 1, revealed over 1,400 articles related to self-efficacy since 1966, of which 363 mentioned the measurement of self-efficacy. All but 22 of these articles were examined to identify 90 self-efficacy measures. These are arranged according to content domain in Table 2. Table 3 contains the frequency and percentage of surveyed instruments in each domain. Taken as a whole, the study reveals several shortcomings in many existing measures of self-efficacy, including the use of potentially inappropriate scale formats, inadequate normative data, and limited evidence of test reliability and validity. Instruments for which the most compelling evidence of reliability and validity are identified are listed in Table 2. These may be suitable models or starting points for construction of new instruments. Table 4 presents information about item/scale characteristics, individuals sampled, reliability, and validity. There are 102 references. (SLD)
