OBJECTIVES: The purpose of this study was to examine the influence of self-esteem and social support on the depression stati of some clinical nurses, and propose basic data for a depression care program. METHODS: Between March 31 and April 5 at 2006, a self-reporting questionnaire survey was administered to 200 nurses at a general hospital located in Gyeonggi-do. The Beck's Depression Inventory (BDI) was used to assess the subjects'depression stati. RESULTS: The average BDI score of the clinical nurses was 8.9+/-7.5, with 59% belonging to the normal category, 28% having mild depressive symptoms, and 13% with a moderate degree of depressive symptoms. The degree of depression was significantly increased in the clinical nurses with a lower self-esteem and less social support. The degree of depression was significantly increased in the clinical nurses with a lower self-esteem and less social support. According to a multivariate regression analysis, a significant association was found between self-esteem and social support in relation to the depression of clinical nurses. The effect of social support was found to not be significant in cases where the self-esteem was high: however, depression was significantly influenced by social support in cases where the self-esteem was low. CONCLUSION: Self-esteem and social support were observed to influence the depression stati of clinical nurses. Therefore, it is suggested that an increase in depression management programs is required to create systematic management to maintain an atmosphere of high self-esteem and close relationships to manage the depression of clinical nurses.
