  • *P values were calculated using either the.

  • †Kruskal-Wallis test.

  • ‡Pearson χ2 test.

  • §MBI-HSS evaluates EE (nine questions), DP (five questions) and LPA (eight questions). Answers are given on a seven-point Likert scale (encoded 0–6) so the maximum value for each dimension could be: EE (54), DP (30), LPA (48). Higher values predict more risk of burnout.

  • DP, Depersonalization; EE, Emotional Exhaustion; LPA, Lack of Personal Accomplishment; MBI-HSS, Maslach Burnout Inventory-Human Services Survey.
