Which occupational risk factors are associated with burnout in nursing? A meta-analytic study

Numerous empirical studies have suggested a link between occupational factors and the burnout syndrome. The effect sizes of the association reported vary widely in nursing professionals. The objective of this research was to assess the influence of five occupational factors (job seniority, professional experience, job satisfaction, specialization and work shift) on the three burnout dimensions (emotional exhaustion, depersonalization and personal accomplishment) in nursing. We conducted a meta-analysis with a total of 81 studies met to our inclusion criteria: 31 on job seniority; 29 on professional experience; 37 on job satisfaction; 4 on specialization; and 6 on work shift. The mean effect sizes found suggest that job satisfaction and, to a lesser extent, specialization were important factors influencing the burnout syndrome. The heterogeneity analysis showed that there was a great variability in all the estimates of the mean effect size. Various moderators were found to be significant in explaining the association between occupational factors and burnout. In conclusion, it is important to prevent the substantive moderators that are influencing these associations. The improved methodological variables explain most of the contradictory results found in previous research on this field. (C) 2013 Asociacion Espanola de Psicologia Conductual.
