    La Escala de Locus de Control (ELOCUS) es un nuevo instrumento de autoinforme para medir las expectativas generalizadas de control en adultos. Se presentan evidencias de validez basadas en la estructura interna de este instrumento. 1324 participantes, mayores de 18 años (M = 37.7 años; DT = 12.8), completaron un cuestionario sociodemográfico y ELOCUS virtualmente. Los análisis fueron Análisis Factorial Exploratorio (EFA) y Análisis Factorial Confirmatorio (CFA) utilizando la muestra completa. Se encontró una solución de dos factores, consistente con el marco teórico, y todos los índices de ajuste fueron satisfactorios. Los coeficientes de consistencia interna fueron adecuados: Fiabilidad compuesta (CC), alfa de Cronbach y omega de McDonald para locus externo de 0.89, 0.83 y 0.84 y para locus interno de 0.96, 0.94 y 0.94 respectivamente. Así, ELOCUS presentó evidencia satisfactoria basada en la estructura interna. Se discuten las limitaciones de este estudio y sugerencias para estudios futuros.

    The Locus of Control Scale (ELOCUS) is a new self-report instrument to measure generalized expectations of control in adults. Accordingly, validity evidence based on the internal structure of this instrument is presented. A total of 1,324 participants, over 18 years of age (M = 37.7 years; SD = 12.8), completed a sociodemographic questionnaire and the ELOCUS in a virtual environment. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted using the full sample. A two-factor solution was found, consistent with the theoretical framework, with all fit indices in both analyses being satisfactory. The internal consistency coefficients were adequate: Composite Reliability (CR), Cronbach’s alpha and McDonald’s omega of 0.89, 0.83 and 0.84 for the external locus and 0.96, 0.94 and 0.94 for internal locus, respectively, were found. Therefore, the ELOCUS presented satisfactory evidence based on the internal structure. Limitations of this study and suggestions for future studies are discussed.
