The General Self Efficacy Scale (GSES-12) is a short version of the Sherer's Self-Efficacy Scale, and evaluates a general dimension and three aspects of self-efficacy: initiative, persistence and effort. The aim of this study is to explore the factorial structure, reliability, and criterion validity of the Spanish adaptation of the GSES-12 in general and clinical populations. The sample was composed of 714 volunteers (332 from the clinical population). Results of the principal components analysis yielded a 3-factor structure that was later confirmed through Confirmatory Factor Analysis. Moreover, this study shows good internal consistency and test-retest values, and differences in self-efficacy scores between the clinical and non-clinical groups. The present study demonstrates that the Spanish version of the GSES-12 is a valid and reliable measure, and it adds relevant information to the debate about the dimensional structure of general self-efficacy.
