Abstract:
OBJECTIVES: The purposes of this study were to develop the Korean version of Wahler Physical Symptom Inventory (WPSI), to examine the reliability and validity of it, and to investigate usefulness for diagnosing somatization. METHODS: The normal group was composed of 242 persons consist of middle and high school students, university students, and adults living in Seoul, Puchon, and Suwon. The two clinical groups consisted of 33 persons with somatic symptoms and 38 diabetic patients. RESULTS: Internal consistency (Cronbach alpha=.91) was very high. Test-retest reliability was calculated from 46 university group, and it's correlations was also high (.87). And the total score of K-WPSI was significantly and positively correlated with subscales of SCL-90-R. There was significant difference between the normal, psychiatry group, and diabetic group of K-WPSI (F=15.48, p<.001). Especially, K-WPSI was very useful to differentiate between the somatization group and diabetic group. CONCLUSION: K-WPSI was found to be a reliable and valid instrument for diagnosing somatization, and for differentiating somatization and diabetic groups. K-WPSI is a brief and economical questionnaire, which may curtail medical expenses of patients. It is also expectated that K-WPSI can be used for identifying somatization and providing information which may contribute to ascertain diagnosis. The limitation of this study is the small normative data, and not distinguishing sex differences. This limitation should be supplemented by future studies.
