The validity and Reliability on Korean Version of Washington Psychosocial Seizure Inventory: Cross-Cultural Comparisons / 대한간질학회지

PURPOSE: The aim of this study was 1) to confirm the reliability and validity of a Korean version of Washington Psychosocial Seizure Inventory (K-WPSI), 2) to investigate the psychosocial functioning of epilepsy patients from Korea, and 3) to compare with other countries. METHODS: The subjects were 302 patients with epilepsy (above 18years). They completed K-WPSI of 132 items including 11 subscales:family background, emotional adjustment, interpersonal adjustment, adjustment to seizures, medical management, overall psychological functioning, Blank, Lie and Rare. We assessed internal consistency, item-subscale correlations, and split-half reliability. Construct validity was assessed by correlating scales of Psychosocial Rating Sheet and K-WPSI. K-WPSI profiles were compared with those from the West Germany, Finland, Canada, the United States, Chile, Dutch, and Japan. RESULTS: The internal consistency estimated by cronbach's alpha coefficient was .934 and split-half reliability coefficient was .876 for adequate reliability (p<.01). Each of subscales in the K-WPSI were high correlated with theoretically similar scales but correlation between theoretically dissimilar subscales was not high. And K-WPSI subscales were significantly related to the PRS subscales. It showed that the Korea epilepsy patients had serious problems in emotional, interpersonal, vocational adjustment, financial status, adjustment to seizure, and overall psycho-social functioning. Comparing the outcomes of various countries, epilepsy patients from Korea and chile had the most serious problem in most areas of psychosocial functioning. CONCLUSIONS: K-WPSI could be a useful test in Korea for reliable determination of the various psychosocial problems of epilepsy patients but modifications of the limitation of the Lie scale may be needed. Comparing the results of other countries, Korea epilepsy patients have been experienced serious psychosocial problem. To solve this problem, social policy and medical and emotional supportive system for persons with epilepsy should need to be established.

A Preliminary Study on the Standardization of the Korean Versions of Wahler Physical Symptom Inventory / 신경정신의학

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.
