저자는 1989년 McCarney(1989)에 의해 개발되어 신뢰도와 타당도가 입증된 주의력 결핍 장애 평가척도-교사판(ADDES-SV)의 한국형을 개발하여, 신뢰도와 타당도를 검증하고, 한국실정에서 ADHD 환자를 선별할수 있는 평가용 도구로 적합한지 여부와 ADHD를 연구할 도구로 사용 할수 있는지를 알아보고자 본 연구를 시행하게 되었다. 1996년 10-11월사이에 대상은 대구, 경북에 소재한 4개 초등학교 2학년 아동 263명과 1996년 6-10월사이에 ADHD 환자 28명을 대상으로 하였으며, 진단은 DSM-IV의 기준에 근거 하였다. 문항번역은 2명의 신경정신과 전문의와 1명의 사회 사업가와 1명의 아동 심리학자에 의해 이루어졌다. 검사-재검사 신뢰 검증에서 신뢰도 계수는 주의산만 계수 0.88, 충동성 계수 0.80, 과잉운동 계수 0.83, 전체점수 0.83이었고(p<0.05), 내적 일관성에 대한 신뢰도 검증에서 Cronbach의 ${\alpha}$값은 주의산만, 충동성, 과잉운동 소척도에서 각각, 0.98, 0.87, 0.96 (p<0.05)이었고, 반분신뢰도 계수는 주의산만 소척도에서 part 1: 0.96(p<0.05), part 2: 0.95(p<0.05), 충동성 소척도에서 part 1: 0.95(p<0.05), part 2: 0.93(p<0.05), 과잉 운동 소척도에서 part 1: 0.92(p<0.05), part 2: 0.94(p<0.05)이었다. 각 소척도간의 상관은 주의산만 소척도와 충동성 소척도와의 상관계수는0.87(p<0.05), 충동성 소척도와 과잉운동 소척도와의 상관계수는 0.95(p<0.05), 주의산만 소척도와 과잉운동 소척도와의 상관계수는 0.88(p<0.05)로 각 소척도간의 높은 상관관계를 보여주고, 검사자간 신뢰도는 주의산만 소척도 0.92, 충동성 소척도 0.87, 과잉운동 소척도 0.89, 전체점수 0.89였다. 본 교실에서 한국형을 개발하여 신뢰도와 타당도를 입증한 CAP척도와의 공존 타당도 검사에서는 환자군에서 0.85, 대조군에서 0.79의 상관관계를 얻었다. ADHD 환자군과 정상 대조군간의 감별 타당도 검증에서 모두 유의하게 환자군이 높은 점수를 보였다. 판별력 검증에는 정상대조군은 100%에서 정상으로, 환자군은 89.2%에서 환자군으로 판별되어 전체 판별력이 94.6%로 나타났으며, Cmax공식을 적용했을 때 89.2%의 판별력의 개선율을 보였다. 따라서, ADDES-SV척도는 한국인의 ADHD를 평가하기 위한 도구로서 신뢰도와 타당도가 높은 것으로 나타났으며, 향후 ADHD에 대한 선별검사 및 역학 조사 연구에 유용한 도구인 것으로 판단된다.

Objective : This study was conducted to examine the reliability and validity of the Measure of Constructs Underlying Perfectionism-Korean version (M-CUP-K). Methods : Two hundred and six normal subjects completed a battery of measures including M-CUP-K, Frost Multidimensional Perfectionism Scale-Korean version (FMPS-K), and Beck Depression Inventory (BDI). Psychometric properties of the M-CUP-K were analyzed. Results : The principal component analysis for construct validity resulted in 56 items composed of 6 factors (factor 1 : Dissatisfaction-Reactivity to Mistakes; factor 2 : Order-Details and Checking ; factor 3 : Satisfaction ; factor 4 : High standards ; factor 5 : Perceived Pressure from Others-Perfectionism toward Others ; factor 6 : Black and White Thinking about Tasks and Activities), compared to the original version. The M-CUP-K total and subscale scores were more strongly correlated with those of the other perfectionism-specific measure, FMPS-K, with a correlation of 0.822 (convergent validity) than with those of the nonspecific depression measure (discriminant validity). The Cronbach's ${\alpha}$ value for internal consistency of M-CUP-K was in an excellent range (r=0.872-0.935). The test-retest reliability for external validity suggested a good temporal stability with a total score correlation of 0.827. Conclusion : This study revealed that the M-CUP-K has good reliability and validity. Therefore, the M-CUP-K can be used as a promising measure of perfectionism in Korea.

Questionaires on symptoms of respiratory disease have been used in Korea to elicit the probable health effects of air pollution in epidemiologic studies: The objectives of such studies often include comparing prevalence of symptoms of respiratory system between different population groups or between the same population groups, at different times. Unfortunately, little attention has, been paid to standardization of those questionaires, whether those are Korean. versions or not. Furthermore, no attempt to develop Korean ,questionaire on respiratory symptoms and relevant information has been made. Followed by 'a comparative study on responses to Korean version questionaires(English origin) of CMI, MRC, and ATS-DLD-78' two types of questionaires on respiratory symptoms and relevant information for Korean adult, which are short form (SUN-81-AS) and long forms (optional questions are added to the short one, SUN-81-AL), have been designed suitable to Korean background by authors (see Annex). The self-administered and closed-question questionaire were tested their validity and reliability by administration to l80 normal adults (medical and nursing students) and 60 clinical patients of Seoul National University Hospital, with spirometric exam. The results obtained and conclusions drawn are as follow: 1. It took less than 10 minutes to complete the questionaire SNU-81-AS and SNU-81-AL. 2. The test-retest reliability of each questions in AS and AL ,were observed as 92.7% and 92.1%, respectively. And all of the level of agreement are statistically significant with kappa statistic. 3. In addition to higher prevalence rate of symptoms in patients group compared, with, normal. group, the correlations between FEV 1.0/FVC predictive value(%) and number of symptoms were statistically significant inpatients group (See Fig. 1 and, Table 7). 4. The answer rate to optional questions in AL form among those who are not to do was about 10%, while the no-answer rate among who are to do was about 15% in Normal (medical and nursing students) group. 5. From the viewpoints of validity and reliability, the new Korean questionaire (SNU-81-AS and AL) developed by authors are to be recommendable to use in epidemiologic studies on respiratory illness in Korea. The self-administration, however, of optional questions in AL form may not assure the quality of data gathered.

Recent increases of asthma and allergies in childhood made the need for a standardized approach to international and regional comparisons of their prevalence and severity. To address these issues, 'International Study of Asthma and Allergies in Childhood (ISAAC)' is currently underway. In Korea, 'Nationwide Study of Asthma and Allergies in Korean Children' began in 1995 according to ISAAC protocol. ISAAC written and video questionnaires were used in this survey, but their reliability and validity were not evaluated properly yet. In this study, our aim was to evaluate the reliability and validity of two kinds of questionnaires and their usefulness in international and regional comparisons. The test and retest of two questionniares were completed by male(n=110) and female(n=111) middle school students with two and three weeks interval each. Kappa(or weighted kappa) were calculated from each questions and validity coefficients were estimated from those statistics. In Korean version of written questionnaire, the questions for allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and food allergy proved to have high kappa values (or weighted kappa values) and validity coefficients and they can be used in further studies without any correction. But some questions about asthma(especially nocturnal cough, wheezing in exercise, and severe asthma) and drug allergy need to be revised for better under-standing to study subjects. Video questionnaire has the same degree of reliability and validity when compared to written questionnaire and this is the unexpected result. Accordingly, it also need to be revised to overcome the racial and cultural differences of the study subjects. In conclusion, the Korean version of written and video questionnaires may be considered to be useful methods in international and regional comparisons of asthma and allergic diseases in childhood after correction of some questions.

Objectives : This study was designed to develop and standardize a checklist for ergonomic risk factors, and to provide ergonomic guidelines for managing cumulative trauma disorders (CTDs) in automobile assembly lines. Methods : The Checklist for Ergonomic Risk Factors (CERF-1) was developed based on the results of previous studies, and then modified after performing pilot study. Information on the symptoms possibly related with CTDs was obtained using a self-reported Questionnaire from 465 automobile assembly workers. Their job conditions were examined to assess risk factors through both direct observation and video analysis. Results : Rate of detecting risky job through CERF-1 was 85.6%, and was similar to that (88.8%) by Occupational Safety and Health Adminstration(OSHA) checklist but higher than that (63.7%) by American National Standards Institute(ANSI) Z-365. Relationship of the exposure scores derived from CERF-1 with levels of symptom was greater (r=0.49) than OSHA (r=0.28) and ANSI Z-365 (r=0.22). Considering the relationship, jobs scoring higher than 16 could be classified as the Risk Job. and lower than 16 as the Low Risk Job. Sensitivity and specificity of the Risk Job were 92.5 % and 31.5 %, respectively. Odds ratio (OR) after age adjustment was 5.69 (95 % confidence interval 3.15-10.29) for the Risk Job, and these ORs were significantly different from those of the Low Risk Job. The exposure scores were Quite valid, in that the scores at the main survey were significantly correlated with those at the follow-up survey, as suggested by test-retest(r=0.88) and inter-rater reliability(r=0.80). Conclusions : The CERF-1, developed in this study, will be an efficient tool for evaluation of risk jobs for CTDs in automobile assembly lines, and can be used easily by health care providers.

연구목적: 피로는 일차 진료에서 흔한 증상이지만 비특이적 주관적 특성상 명확한 정의와 객관적 평가가 어렵고, 특히 기질적 질환이 없는 피로의 평가는 더욱 힘들다. 이에 저자들은 기질적 질환이 없는 피로 환자에게 Fatigue severity scale (FSS) 을 적용하여 그 유용성을 알아보고자 하였다. 방법: 피로환자 44명, 우울 또는 불안증의 정신과 환자 43명과 대조군 45명에게 피로도, 스트레스, 우울 불안 척도를 이용하여 FSS의 신뢰도와 타당도를 조사하였다. 결과: FSS의 신뢰도 계수는 0.935이었고 재검사의 상관관계 계수는 0.916이었다 (p<0.01). FSS 점수는 피로 군에서 유의하게 가장 높았고 대조군에서 가장 낮았다 (p<0.01). FSS와 Chalder fatigue scale의 상관관계 계수는 0.782로 높았다 (p<0.01). 피로군과 대조군에 대한 FSS index의 최적의 절단점은 민감도 84.1%. 특이도 85.7%인 3.22로 조사되었다. 결론: FSS는 일차진료에서 기질적 질환이 없는 피로환자와 우울 또는 불안증 환자에서 피로도를 평가할 수 있는 유용한 도구이며, 향후 보다 많은 환자를 대상으로 한 연구가 필요하리라 생각된다.

Background and Aims: Colorectal cancer is the second most frequent cancer in Malaysia. We aimed to assess the validity and reliability of the Malaysian Chinese version of European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire core (QLQ-C30) in patients with colorectal cancer. Materials and Methods: Translated versions of the QLQ-C30 were obtained from the EORTC. A cross sectional study design was used to obtain data from patients receiving treatment at two teaching hospitals in Kuala Lumpur, Malaysia. The Malaysian Chinese version of QLQ-C30 was self-administered in 96 patients while the Karnofsky Performance Scales (KPS) was generated by attending surgeons. Statistical analysis included reliability, convergent, discriminate validity, and known-groups comparisons. Statistical significance was based on p value ${\leq}0.05$. Results: The internal consistencies of the Malaysian Chinese version were acceptable [Cronbach's alpha (${\alpha}{\geq}0.70$)] in the global health status/overall quality of life (GHS/QOL), functioning scales except cognitive scale (${\alpha}{\leq}0.32$) in all levels of analysis, and social/family functioning scale (${\alpha}=0.63$) in patients without a stoma. All questionnaire items fulfilled the criteria for convergent and discriminant validity except question number 5, with correlation with role (r = 0.62) and social/family (r = 0.41) functioning higher than with physical functioning scales (r = 0.34). The test-retest coefficients in the GHS/QOL, functioning scales and in most of the symptoms scales were moderate to high (r = 0.58 to 1.00). Patients with a stoma reported statistically significant lower physical functioning (p=0.015), social/family functioning (p=0.013), and higher constipation (p=0.010) and financial difficulty (p=0.037) compared to patients without stoma. There was no significant difference between patients with high and low KPS scores. Conclusions: Malaysian Chinese version of the QLQ-C30 is a valid and reliable measure of HRQOL in patients with colorectal cancer.

Objectives: The aim of this study was to evaluate the reliability and validity of the Korean Version of the Diagnostic Interview Schedule for Children Version IV(DISC-IV), a highly structured diagnostic interview used to assess more than 30 psychiatric disorders in children and adolescents. Methods: A total of 91 study subjects, including 67 subjects who visited the child and adolescent psychiatry outpatient clinic at our institution and 24 community-based subjects, were assessed using the Korean Version of the DISC-IV. Clinical diagnosis was used as a gold standard for the examination of the validity of the DISC-IV. Forty-four of the study subjects were randomly selected for test-retest reliability measurement. Results: The validity of the Korean Version of the DISC-IV showed kappa values ranging from 0.25 to 0.40 in the clinical sample and 0.65 to 1.00 in the community sample. The sensitivities varied according to the diagnostic categories, but the specificities were excellent for all diagnostic entities. Conclusion: The Korean Version of the DISC-IV showed good reliability and validity in Korean children and adolescents. The Korean Version of the DISC-IV might be a useful tool for assessing psychiatric disorders in children and adolescents.

연구목적：자살사고에 관한 1차 선별검사 도구를 개발하고자 현재 세계적으로 널리 사용되고 있는 Reynolds의 자가보고형 청소년 자살사고 설문(SIQ-JR)을 번안하여 우리나라 청소년에 적용하여 한국판 SIQ-JR 척도에 대한 신뢰도 및 타당도를 검증하고자 하였다. 방 법：서울시내 남녀 중고등학생 총 1,160명과, 정신과에 내원한 청소년 임상환자 114명을 연구대상으로 하였다. 연구도구로는 SIQ-JR 이외에, 자살관련 8가지 국내 표준화된 척도(분노, 우울, 불안, 절망감, 공격성, 충동성, 내외통제, 자아평가)를 시행하였다. 결 과：전체 SIQ-JR 총점 평균은 여자가 남자 보다 높았고, 고등학생이 중학생 보다 높았지만 모두 통계적으로 유의미하지 않았다. 임상군의 경우 일반 학생군과 높은 변별력(p<0.01)을 보였다. SIQ-JR의 내적일관성을 나타내주는 신뢰도계수는 0.92-0.94, 검사-재검사 상관계수는 0.68-0.78, 항목-전체 상관계수는 0.59-0.82로 모두 높은신뢰도를 보였다. 요인분석 결과 타인에 대한 고려가 독립된 요인으로 추출되었는데 이는 서구의 개인주의와 다른 우리나라의 문화적 배경을 반영한다고 여겨졌다. 공존 타당도 분석결과 자살사고와 자아평가척도와 분노조절척도 점수와는 역상관관계였으며 나머지 6개 척도와는 정상관관계였다. 전체대상의 자살사고 점수와 가장 연관이 높은 척도는 우울척도(r=0.42), 공격성 척도(r=0.36), 특성불안척도(r=0.35), 분노척도의 하위척도인 내재화된 분노(r=0.31) 순이었다. 남자와 고등학생의 경우 공격성(r=0.37)이 가장 자살사고와 관련이 높은 척도였다. 그러나 절망감척도와 충동성척도는 자살사고와 낮은 상관관계를 보였다. 결 론：이상을 살펴볼 때 한국판 자살사고 척도는 만족할만한 신뢰도와 타당도를 얻었다고 여겨지는바 학교, 지역사회, 임상현장에서 1차적 자살사고 선별검사 도구로서의 활용이 기대된다.
