Sažetak
The aim of this study was to determine moderator and mediator effects of personality traits on relationship between stress and health. The respondent sample comprised of 177 police officers (140 males, 37 females) with an average age of M = 30.86 (SD = 5.41). Following instruments were used: Holmes and Rahe Stress Scale (Holmes & Rahe, 1967), Eysenck Personality Questionnaire (EPQ R/S, Eysenck, 1991), 36 Health Survey (Ware et. al, 2000). Police stress was measured with scale constructed for the purpose of this research, participants gave answers on 5 point Likert scale regarding stressors in police. We expect that personality will moderate and mediate the stress-health relationship. That is, we assume that stress will be significantly linked to health only in those participants with low exstraversion and high psychoticism and neuroticism scores. We also assume that participants with low exstraversion and high psychoticism and neuroticism scores will have worse health outcomes compared to respondents with high exstraversion and low psychoticism and neuroticism scores. Results show that personality has weak mediator effect on stress- health relationship only regarding life stress while no moderator effect was found. Regression analyses were performed in order to investigate if personality mediated the effect of stress on health. The first regression showed that life stress had an unique effect on heatlh ((B = −0.02, p<0.05). The second regression tested whether life stress uniquely predicted the mediator (i.e., neuroticism). Life stress was found to be positively associated with neuroticism (B=0.03, p<0.05). However, life stress was not associated to psychotism and neuroticism (p>0.050) and was therefore removed from further analysis. In the third step neuroticism was negatively assiciated with health (kontroling life stress) (B=-0.549, p<0.05). A hierarchical regression analysis using health as the outcome variable was performed using stress as predictor in the first step, and neuroticism as predictor in the second step. This analysis allows the examination of whether stress predicts health and if this relation is weaken in the presence of neuroticism as the mediator. When neuroticism (i.e., the mediator) was controlled for, predictability was reduced somewhat but was still significant for stress (B = -0.084, p<0, 05). The study suggests that neuroticism contributes directly to explaining the variance in health while stress might contribute directly to explaining the variance in heatlh and indirectly by increasing neuroticism.
