Nuevos planteamientos en la evaluación del burnout. La evaluación específica del desgaste profesional médico

Abstract

Objective. To introduce the development and validation of the Medical Professional Burnout Syndrome Scale belonging to the Questionnaire on Medical Professional Burnout (QMPB). Design. Descriptive and transversal study in two stages. Stage 1: analysis of the psychometric properties of the new questionnaire dealing with its construction validity (exploratory factorial analysis, internal consistency, and confirmatory factorial analysis). Stage 11: study of its convergent validity with the Maslach Burnout Inventory (MBI). Setting and participants. Community of Madrid, Spain. Stage I: 485 doctors (primary care centres and hospitals). Stage II: new sample of 100 doctors (primary care centres). Main measurements. Professional burnout through the Medical Professional Burnout Syndrome Scale and the Maslach Burnout Inventory. Results. The exploratory and confirmatory factorial analysis of the QMBP confirmed 3 factors that described medical professional burnout: Exhaustion, Distancing, and Loss of Hope, with an acceptable internal consistency. Convergent validity was confirmed with the MBI, especially in the Exhaustion dimension. Conclusions. Evaluation of psychometric properties confirmed the Medical Professional Burnout Syndrome Scale as a valid and specific instrument for studying burnout.
