Estrés laboral y calidad de vida en sanitarios de atención primaria: Una prueba de la validez del cuestionario PECVEC

Abstract

Objectives. To evaluate the relationship between Health-Related Quality of Life (HRQL) and stress at work among Primary Care workers, as evidence of the construct validity of the Spanish version (PECVEC) of the profile of quality of life in the chronically ill (PLC) questionnaire. In addition, to check its other psychometric properties. Design. Cross-sectional study. Setting. Eighteen primary care centres in Health Area IV, Asturias (Oviedo), Spain, sharing similar socio-demographic conditions. Participants. Two hundred and thirty-three primary care nurses and physicians. Main measurements. HRQL was evaluated by the 6 general dimensions of the Spanish version of the PLC. Stress at work was evaluated by the three scales of the Effort-Reward Imbalance (ERI) questionnaire. Results. The construct validity of the PECVEC was assessed by testing the inverse associations of QoL dimensions and job stress ones, when the most important confuser variables were monitored. The non-response rate was low (<3%), and no floor effects and only small ceiling effects were observed. Internal consistency analysis and exploratory and confirmatory factor analysis demonstrated high reliability, factorial validity and convergent/divergent validity of the PECVEC. Conclusions. The PECVEC demonstrates adequate psychometric properties for evaluating HRQL in healthy subjects.
