Psychometric validation of the UNIPSICO questionnaire in Valencian/Catalan: analysis of scales for evaluating psychosocial resource variables

Abstract

This study aims to analyse the psychometric properties of the resources scales of the UNIPSICO questionnaire for the Valencian/Catalan version. The sample was 1359 teachers from public centres in the province of Valencia. Data collection was carried out using the UNIPSICO questionnaire scales that evaluate psychosocial factors of resources at work (30 items), which are grouped into five scales: Resources (7 items), Social support at work (6 items), Feedback (8 items), Autonomy (5 items), and Transformational leadership (4 items). A confirmatory factor analysis (CFA) was performed and Cronbach’s alpha and McDonald’s omega values were calculated for the scales. All items presented adequate statistical and psychometric values. The five-factor model that reproduces the original structure of the questionnaire presented an adequate fit to the data, and gender invariance. The Cronbach’s alpha and McDonald’s omega values were acceptable for the five scales of the instrument. These results contribute to the psychometric validation of the questionnaire and they permit the conclusion that the resources scales of the UNIPSICO questionnaire translated into the Valencian/Catalan language are a reliable and valid instrument to assess psychosocial risks in non-university teaching personnel.
