Personality moderators of the cross-sectional relationship between job demands and both burnout and work engagement in judges: The boosting effects of conscientiousness and introversion.

The central question of this study is whether buffering, boosting and exacerbating effects of the Big Five personality factors extraversion, openness to experience, agreeableness, conscientiousness and neuroticism can be demonstrated in the relationship between two job demands (i.e., work pressure and working overtime) and both burnout and work engagement in 257 Dutch judges. It is important to better understand the interaction effects between various job demands (work pressure and working overtime) and personality on both burnout and work engagement in judges given their increased risk of burnout and lower work engagement due to cognitively and their emotionally demanding work. Three hypotheses were tested in a cross-sectional design study. Moderation analyses showed that, as expected, conscientiousness significantly boosted the relationship between working overtime and work engagement. Hence, high scorers on conscientiousness showed more work engagement when working overtime. Also, extraversion moderated the relation between working overtime and work engagement, but only at a low level of extraversion. Thus, contrary to expectations, introverts showed more work engagement when they work overtime. Also, significant main effects were found. Work pressure and neuroticism related positively to burnout, while extraversion and agreeableness related negatively to burnout. Moreover, extraversion, agreeableness and conscientiousness related positively to work engagement. In our study, conscientiousness, extraversion and agreeableness can be considered as personal resources for judges, in line with the Conservation of Resources (COR) theory. Especially conscientiousness can facilitate judges to cope with challenging working circumstances and introversion ensures that judges stay engaged despite working overtime.
