The Meta-Analysis of the relationship between stress job and personality variables

In recent decades، many studies have examined the relationship between job stress and personality variables. But the results are not consistent and sometimes different results have been reported. Meta-analysis is a systematic technique to solve different resultsin the findings studies about the same topic. Accordingly، the aim of the present research was a meta-analysis of the association between job stress and personality variables. Data collected from 106 studies conducted from 1993-2013 and was analyzed then the effect sizes were computed. Findings revealed that the combined effect size for fixed model was 0. 23 and for random model was 0. 24، which both were small effect sizes) Cohen، 1988). Further meta-analysis showed that the Positive affect، anxiety، burnout، perfectionism، time management، hardiness، resiliency، assertiveness variables had significant large positive effects size on job stress. We checked for Publication bias and heterogeneity of effects. The results showed no bias but due to heterogeneity of effects، demographic and methodological variables were examined. Findings revealed that sampling، kind of job، kind of studies and Measuring tools could moderate the relationship between job stress and personality variables as the moderator effects. The overall results suggested that personality variables that emphases on self-understanding have more impact in reducing job stress. Therefore، a further study in this area is needed.
