Abstract:
OBJECTIVES: The purposes of this study are to investigate the reliability and validity of shortened premenstrual assessment form and the applicability to internet interface. METHOD: The total of 55 subjects were included in this study. Among them, 28 subjects had premenstrual dysphoric disorder, and the other 27 subjects did not. All subjects performed the shortened premenstrual assessment form through internet interface in the homepage of Severance Woman Clinic. The diagnosis of premenstrual dysphoric disorder was determined by prospective assessment for 2 months. RESULTS: The shortened premenstrual assessment form consists of 3 factors: affect, pain and water retention. The test-retest reliability of this scale was 0.80, and internal consistency (Cronbach alpha) was 0.91. The correlation coeffeciecy between scores of the premenstrual assessment form and the shortened premenstrual assessment form was 0.92. The difference of the scores of the shortened premenstrual assessment form between the group of premenstrual dysphoric disorder and the group of non-premenstrual dysphoric disorder was significant (t=5.57, p<0.001). Discriminant analysis also revealed that the shortened premenstrual assessment form was useful to differentiate between premenstrual dysyphoric disorder and non-premenstrual dysphoric disorder (eigenvalue: 0.60, canonical correlation coefficiency: 0.61, Wilk's lambda: 0.63). The cut-off point to differentiate between two groups was 27, and sensitivity (75.0%) and specificity (76.9%) of this scale for premenstrual dysphoric disorder was acceptable. CONCLUSION: In summary, the shortened premenstrual assessment form appeared to be reliable and valid for the assesment of premenstrual dysphoric disorder. And the results of this study also suggest that the shortened premenstrual assessment form is a useful tool for internet interface application.
