Validation of the Arabic Version of the Maslach Burnout Inventory-HSS Among Tunisian Medical Residents (A-MBI-MR): Factor Structure, Construct Validity, Reliability, and Gender Invariance

<b>Background</b>: Burnout is a major problem for physical and mental health of medical residents. The key for maintaining well-being and quality of care of residents is the assessing tool. The study evaluated the psychometric properties of the Arabic version of the Maslach Burnout Inventory Human Services Survey (MBI-HSS) among Tunisian medical residents by assessing its factor structure, construct validity, reliability, and gender invariance. <b>Methods</b>: A total of 552 residents, aged 27.01 ± 1.92, 219 males (39.7%) and 333 females (60.3%) completed the Arabic version of the A-MBI-MR. The exploratory (EFA) and confirmatory factor (CFA) analyses were performed to identify the factor structure, with assessments of internal consistency of the model, including gender measurement invariance. <b>Results</b>: The results indicate a high average variance extracted (AVE > 0.50) and factor loading of the scale, signifying robust construct validity and clearly suggesting that the items serve as essential indicators for assessing several dimensions of burnout. The reliability analysis demonstrates excellent and acceptable internal consistency across all areas of emotional exhaustion, personal accomplishment, and depersonalization (Cronbach's α = 0.95, 0.98, and 0.871) respectively. The CFA confirmed the three-factor structure of the A-MBI-MR, with fit indices indicating an adequate model fit: CFI = 0.945, TLI = 0.938, GFI = 0.951, RMSEA = 0.074, RMSEA CI (0.066, 0.081), RMSEA <i>p</i>-value= 0.000, SRMR = 0.044. Results from the measurement invariance analysis of the MBI scale demonstrated robust invariance between male and female participants. <b>Conclusions</b>: The MBI-MR in Arabic for medical residents is reliable, valid, and effective for measuring burnout levels in Arabic-speaking regions.
