Work self-efficacy scale: Validity and accuracy evidence

Abstract

The article presents psychometric quality studies for the Work Self-Efficacy Scale (WSES): one is a validity study based on the internal structure (Exploratory Factor Analysis, EFA, and Confirmatory Factor Analysis, CFA), and the other an accuracy study through internal consistency. In the validity study based on the EFA and accuracy, the WSES was applied in a sample of 525 workers, resulting in a reduction to 23 items, distributed in two factors (factor 1, Work Execution, with factorial loads varying between 0, 47 and 0.89, and factor 2, Interpersonal Labor Relations, with loads between 0.56 and 0.85). The Orion accuracy coefficients were 0.96 (factor 1) and 0.95 (factor 2). In the CFA, the WSES with 23 items was applied to a sample of 200 workers, and it was verified that all the indicators presented adequate values, and the structure (two factors) of the WSES was also confirmed.
