PURPOSE: The purpose of this study was to identify the effect of Psychosocial health and Self-nurturance on the experience of new graduate nurses. METHODS: A cross-sectional survey design was used. The participants in this study were 149 nurses who had less than 12 months of nursing experience and were working at one of 4 general hospitals. The data were collected by a self-administered questionnaire from Nov. 2012 to Oct. 2014. RESULTS: The total mean score for Psychosocial health was 3.07+/-0.60, Self-nurturance, 3.38+/-0.44, and graduate nurse experience, 2.59+/-0.27. The effect of Psychosocial health and Self-nurturance predicted 23% of variance in graduate nurse experience. CONCLUSION: These results indicate that Psychosocial health and Self-nurturance have a positive relationship to graduate nurse experience. Therefore, further studies including approaches that support Psychosocial health and Self-nurturance are recommended to help in the adaptation of newly graduated nurses to clinical settings.
