Perceived stress latent factors and the burnout subtypes: A structural model in dental students

Background: Students of health-professions suffer high levels of stress and burnout. The aim of the present study was to evaluate the relationship between perceived stress latent factors (''tenseness'' and ''frustration'') and the features (''overload'', ''lack of development'' and ''neglect'') of the three burnout subtypes (''frenetic'', ''under-challenged'' and ''worn-out'', respectively), in a sample of Spanish dental students. Methods: The study employed a cross-sectional design. A sample of Spanish dental students (n = 314) completed the ''Perceived Stress Questionnaire'' and the ''Burnout Clinical Subtype Questionnaire Student Survey''. The associations among variables were observed by means of structural equation modelling using the unweighted least squares method from polychoric correlations. Results: Strong associations among perceived stress factors and the burnout characteristics were observed, although a distinct pattern of relations was observed for each burnout subtype. The ''overload'' was moderately and positively associated with both ''tenseness'' (0.45), and ''frustration'' (0.38) dimensions of perceived stress; the ''lack of development'' was positively associated with the ''frustration'' dimension (0.72), but negatively associated with ''tenseness'' (20.69); the ''neglect'' showed a weaker positive associated with ''frustration'' (0.41), and a small negative association with ''tenseness'' (20.20). The model was a very good fit to the data (GFI = 0.96; RSMR = 0.07; AGFI = 0.96; NFI = 0.95; RFI = 0.95). Conclusions: The stress factors of ''frustration'' and ''tenseness'' seems to be related in a distinct way to the burnout subtypes in Spanish dental students. This finding suggests that intervention programs specifically tailored to these subtypes may be a promising future direction
