Abstract
There is a lack of evidence about burnout syndrome among Lithuanian dentists; as a reliable instrument to examine the syndrome in this professional group has not yet been tested. The study aimed to investigate the performance of the items and the subscales of the Maslach burnout inventory (MBI) by validating its factorial structure and analyzing its variance between demographic and workload groups of dental professionals in Lithuania. The survey was conducted among practicing dentists online or during the scientific conferences for dentists using an anonymous questionnaire. To evaluate the level of burnout the MBI was chosen. Reports of a total of 380 respondents were examined. Three-factor structure of the MBI with cross-loading of two items suggested a good fit to data (χ2/df = 1.67; CFI = 0.93; TLI = 0.93; IFI = 0.93; and RMSEA = 0.059) and was invariant across demographic and workload groups of dentists. Multigroup factorial analysis revealed that females as compared to males had higher average emotional exhaustion; and the respondents up to 30 years as compared to respondents over 30 years of age had higher averages of the emotional exhaustion and depersonalization components. Highly specialized dentists (oral surgeons, prosthodontists, orthodontists, endodontists and poedodontists) were particularly less prone to burnout syndrome than dentists of general practice. It was concluded that the MBI offers factorial validity and demonstrates its invariant structure and variance of burnout dimensions across demographic and workload groups. These findings are informative for burnout prevention and intervention programs among dentists in Lithuania. Such information may contribute to lessen professional burnout among dentists in Lithuania.
Highlights
Job burnout in healthcare professionals has become a challenge for researchers around the globe during the past few decades [1,2,3]
The purpose of the present study was to investigate the performance of the items and the subscales of the Maslach burnout inventory (MBI) by validating its factorial structure and analyzing its variance between demographic and workload groups of dental professionals in Lithuania
The findings of the present study suggest that as a whole the Maslach burnout inventory presents an adequate factorial validity and its three dimensions demonstrate sufficient variance of burnout dimensions between demographic and workload groups among dentists in Lithuania
Summary
Job burnout in healthcare professionals has become a challenge for researchers around the globe during the past few decades [1,2,3]. Various theoretical models and research studies from many countries have contributed to a better understanding of the causes and consequences of this professionally specific disorder of well-being and ability to work [4,5,6,7]. Numerous systematic reviews and meta-analyses on burnout of physicians and nurses have been published currently [8,9,10,11]. Res.
