A scale was developed to assess undergraduate students' negative and positive events in interpersonal and achievement domains. Two studies were conducted for assessing validity of this scale. In Study 1, in which 279 female subjects participated, correlations between the scores of life event scale and those of two other scales assessing depression (SDS) and subjective well-being were examined. In Study 2, in which 94 male and 108 female subjects participated, correlations between the scores of life event scale and those of two other scales assessing depression (BDI) and self-esteem were examined. Result of these studies showed high construct validity of life event scale. In addition to the 119-item full varsion of scale, its 60-item short version was presented.
