Many people suffer from life stress, but some people report growth after these stress events. The purpose of the present study is to develop Trauma and Stress-Related Growth Scale(TSRGS), a valid measure of the growth experienced by Koreans through general stress events as well as traumatic events. In Study 1, in order to develop items of a scale that measures the actual growth that Koreans experience, interviews were conducted for those who experienced growth or positive changes after stress events. The result of interviews were analyzed qualitatively to assume theoretical sub-factors, and the content validity was evaluated by the experts. Next, in the preliminary survey of Study 1, appropriate items were selected first through the item analysis comparing the reliability, discrimination, and response distribution of each item, and in main survey the exploratory factor analysis with polychoric correlation coefficients were conducted to draw the final items and factor structure of TSRGS. The sub-factors consist of (1) increased sense of value in life, (2) positive evaluation from others, (3) increased acceptance of others, (4) increased hardiness, and (5) increased integrity of emotions. In Study 2, the confirmatory factor analysis, correlation analysis with other scales such as post-traumatic growth scale, meaning scale of life, and event-related rumination scale, and measurement invariance test were conducted to secure the construct and concurrent validity of TSRGS. Finally, Based on the results, clinical utilization of TSRGS is discussed and further research is proposed.
