Construcción y validación de una escala de autoeficacia en el trabajo.

The main objective of this study was to construct and validate a scale of self-efficacy at work that is applicable to transversal work contexts. The sample consisted of 332 Chilean workers randomly divided into two subsamples. The study was conducted in four phases: 1) instrument design, 2) content validation, 3) exploratory factor analysis (subsample A), and 4) confirmatory factor analysis (subsample B). The results for the full scale showed adequate adjustment indicators (CFI = 0.97; TLI = 0.97; RMSEA = 0.05; Cronbach's alpha = 0.948). The scale was conformed into five dimensions: self-management, transfer, metacognition, meta-learning, and self-care. Their respective Cronbach's alphas (0.858; 0.869; 0.808; 0.826 and 0.854) certified adequate internal consistency. In conclusion, the self-efficacy at work scale generated here showed adequate psychometric characteristics for its use, both at the level of the entire scale and at level of each of its dimensions.
