RESUMO
BACKGROUND: We divided hospital workers into two groups according to whether one was an interpersonal service worker (ISW) or was not (non-ISW). We then explored differences between these groups in job stress and emotional labor type and investigated the mediating factors influencing their relationships. METHODS: Our participants included both ISW (n = 353) and non-ISW (n = 71) hospital workers. We administered the Korean Standard Occupational Stress Scale Short Form to measure job stress and the Emotional Labor Scale to indicate both emotional labor type and characteristics. We also administered the Beck Depression Inventory-II to indicate the mediating factors of depressive symptoms, the Beck Anxiety Inventory to indicate the mediating factors of anxiety, and the State Anger Subscale of the State-Trait Anger Expression inventory to indicate the mediating factors of anger. RESULTS: The ISW group showed more severe job stress than the non-ISW group over a significantly longer duration, with greater intensity, and with higher level of surface acting. The ISW group showed a significant positive correlation between surface acting and job stress and no significant correlation between deep acting and job stress. Parallel mediation analysis showed that for ISWs surface acting was directly related to increased job stress, indirectly related to depression, and unrelated to anxiety and anger. CONCLUSION: The ISW group displayed more surface acting and job stress in its emotional labor than the non-ISW group. In the ISW group, surface acting during emotional labor was positively correlated with job stress. Depression partially mediated their relationship.
