Validation of the medium and short version of CENSOPAS-COPSOQ: A psychometric study in the Peruvian population

Abstract

Background: The presence of psychosocial risks at work is associated with mental and physical health issues in workers. The study aim was to adapt the COPSOQ-ISTAS21 Medium-Version to the Peruvian context and to develop a Short-Version of the instrument.Method: Cross-sectional design study. The COPSOQ-ISTAS21 Medium Version was used. A confirmatory factor analysis was performed to determine the internal structure of each subdimension (first-order) and dimension (second-order) using the Robust Maximum Likelihood estimation method, and classic fit indices in the literature (CFI, SRMR, RMSEA). Internal consistency was evaluated using the alpha and omega coefficients. A short version was developed based on the items with the highest factorial load and that reduce the factorial complexity.Results: A total of 1707 participants were evaluated. In the confirmatory factor analysis, the goodness-of-fit indices for seventeen of the 20 one-dimensional models (subdimensions) were identified; two subdimensions could not be evaluated because they presented only two items. When conducting a multidimensional analysis, we identified that all second-order models presented optimal goodness-of-fit indices, except “psychological demands at work”. The latter required adding four pairs of correlated errors to reach adequate fit values. Finally, a short version of only 31 items was designed from the items with optimal fit indices.Conclusions: The new adapted versions of COPSOQ-ISTAS21 were renamed CENSOPAS-COPSOQ. The CENSOPAS-COPSOQ is an instrument with sufficient evidence of validity and reliability in its medium and short version, which is why its use is recommended in Peruvian work centers to identify the evaluation and prevention of psychosocial risks at work in Peru.

Riesgos psicosociales en personal de salud del Perú: análisis de propiedades psicométricas del ISTAS 21

“…5,7,9,15,16 Presenta evidencias de validez y confiabilidad ( > .70) en sus versiones mediana y breve para la evaluación y prevención de riesgos psicosociales en población peruana. 17 La calificación de las respuestas se basa en una escala de tipo Likert (0=nunca a 5 puntos= siempre). El cuestionario está conformado por 20 ítems y comprende cinco dimensiones que se basan en escalas de salud general, salud mental y vitalidad: (1) "Exigencias psicológicas" (carga de trabajo de tipo cuantitativas, cognitivas, emocionales, esconder emociones y sensoriales); (2) Trabajo activo y desarrollo de habilidades (influencia en el trabajo, posibilidades de desarrollo, control de tiempo en el trabajo, sentido del trabajo, integración en la empresa); (3) Apoyo social en la empresa y calidad del liderazgo (previsibilidad, claridad de rol, conflicto de rol, calidad de liderazgo, apoyo social de compañeros, apoyo social de superiores, posibilidades de relación social, sentimiento de grupo; (4) Compensación (estabilidad); y (5) Doble presencia.…”
