Psychometric properties of the arabic version of the maslach burnout inventory-human services survey (MBI-HSS) among lebanese dentists

BACKGROUND: Dentists are at risk of burnout syndrome, which can have negative impacts on their work environment and productivity. Assessing burnout is crucial for maintaining the well-being and effectiveness of dentists in their profession. The present study aims to evaluate the psychometric properties of the Arabic version of the Maslach Burnout Inventory Human Services Survey (MBI-HSS) among dentists. METHODS: The original English version of the MBI-HSS was translated into Arabic, and then back-translated into English by experienced bilingual professionals. Lebanese dentists were asked to participate in the study between February and June 2019. Data collected included demographic information and items from the Arabic version of the MBI-HSS. RESULTS: A total of 441 people participated in the study, of whom 58.3% were men. The mean age of the sample was 39.6 years (SD = 12.8), with a range of 23 to 68 years old. Approximately 60% of dentists were specialists. Cronbach’s alphas were as follows: emotional exhaustion (alpha = 0.855), depersonalization (alpha = 0.823), and personal achievement (alpha = 0.667). The results of the test-retest reliability assessment demonstrated the strong reproducibility of the MBI-HSS [EE, ICC = 0.927 (0.845, 0.966), p-value < 0.0001; PA, ICC = 0.963 (0.921–0.983), p-value < 0.001; DP, ICC = 0.764 (0.497–0.889), p-value < 0.0001]. The exploratory factor analysis of the MBI-HSS yielded three psychometrically robust sub-domains representing dimensions of “emotional exhaustion,” “depersonalization,” and “personal achievement,” which explained 57.8% of the scale’s total variance. The confirmatory factor analysis revealed that the 15-item model (excluding items 4, 5, 12, 13, 16, 20, and 22) was the most fitting for the data. CONCLUSIONS: The Arabic version of the MBI-HSS scale demonstrated good psychometric properties in Lebanese dentists. However, it would be important to conduct further research to confirm its reliability and validity in other Arab countries.
