  • Objectives: Parkinson's disease is one of the most common neurodegenerative diseases in the elderly population. In order to estimate the prevalence of Parkinson's disease in the community, the application of a good screening tool is essential. We evaluated the validity and reliability of a Parkinson's disease screening questionnaire and propose an alternative measure to improve its validity for use in community surveys. Methods: We designed the study in a three-phase approach consisting of a screening questionnaire, neurologic examination, and confirmatory examination. A repeated survey was administered to patients with disease detected in the community and on 150 subjects. We examined internal consistency using Cronbach's alpha test, test-retest reliability using the kappa statistic, and validity using sensitivity, specificity, and ROC curves. Unadjusted odds ratios were utilized for the estimation of weights for each questionnaire item. Results: The Cronbach's alpha of the questionnaire was 0.708. The kappa statistic for test-retest reliability was good to generally fair in most of the items. When newly proposed weighting scores were used, the optimum cut-off value was 7/8. When cut-off value was 5/6 for surveying prevalence in a community, the sensitivity was 0.98, and the specificity was 0.61, with simultaneous improvement in reliability. Conclusions: We recommend 5/6 as the ideal cut-off value for the survey of PD prevalence in community. This questionnaire designed for the Korean community could help future epidemiologic studies of PD.

  • The purpose of this study was the development of a scale to assess maternal anxiety after mother-child separation. Subjects consisted of 384 mothers who had children from 6 to .36 months of age. A questionnaire consisting of eighty Likert-type items and Spielberger's(1970) State Anxiety Scale were administered to mothers and data were analyzed using item analysis. factor analysis. multiple regression. Cronbach's ${\alpha}$. Pearson's correlation and F-test. Sixty of the eighty items were significant and deemed acceptible through item discrimination method with indices ranging from. 32 to .95. Factor analytic procedures have selected 54 items of the 60-item scale and supported a 5-factor solution. The subscales labeled 'Maternal Separation Anxiety'. 'Perception of Separation Effects on the Child', 'Desire for Physical Cuddling and Closeness'. 'Attitudes toward the Value or Importance of Exclusive Maternal Care' and 'Employment-related Separation Concerns,' Finally. a multiple regression analysis conducted to reduce the length of the scale yielded a 39-item form for the Maternal Separation Anxiety Scale(MSAS). Internal consistency of the MSAS was high(Cronbach's ${\alpha}$ =.85). The correlation of the MSAS with the Spielberger's State Anxiety measure yielded a coefficient of .36, revealing a moderate and positive relationship.

  • 1. Objectives : This study aimed to assessing the reliability of questionnaire for Japanese as one of method to diagnose Sasang Constitution and evaluating the possibility of applying domestic questionnaire to foreign site. 2. Methods : A cross-sectional survey approved by IRB (Independent Review Board) at Tohoku University was performed for 119 participants with informed consent at a particular city in Japan using self-reported questionnaires developed by KIOM (Korea Institute of Oriental Medicine). Among the entire samples, 112 were retested. The test-retest reliability was assessed by Kappa for normal variables and internal consistency was evaluated by Cronbach's alpha. 3. Results : Four of 77 questions are impossible to calculate consistency owing to unsymmetric matrix between primary reply and secondary one. Seventeen of them (22%) showed 0.4 or below in Kappa, 56 were ranged from 0.4 to 0.8 and no question marked 0.8 or over. Internal consistency was possibly checked for several questions about character, digestion, sweat, excrement, urine, cold-heat pattern. Cronbach's alpha for questions except urine and cold-heat pattern was over 0.6 4. Conclusions : On the basis of Kappa value by two self reported questionnaire, 72.7% of questions showed 0.4 or over so that reliability were highly secured. And other questions except for urine and heat-cold pattern marked 0.6 or over in order that internal consistency was also successfully maintained. Accordingly, when subsequently applying KIOM questionnaire to foreign site, domestic questionnaire should be properly adjusted in social and cultural background, lifestyle, etc.

  • The purposes of the study were to develop an instrument for family value and to identify the relationships of family value, family hardiness, and family adaptation by appling the family value scale to family with cancer children. The study was conducted in three phases. 1) A survey was conducted from July 20 to August 20, 1999 and 18 items of general family value scale was modified from the data of 153 fathers and 164 mothers. 2) In-depth interviews were made with 29 parents of cancer children from April 20, 1998 to May 20, 1999 to develop family value scale with cancer children, and 12 statements were developed. 3) The final survey was conducted from July 18, 2000 to August 30, 2000 and the data from 309 parents of children who are diagnosed as cancer, 18 or less years of age, and treated either hospitalized or at the outpatient clinics were analyzed to identify the relationships of the concepts. The data analysis utilized SAS 6.12 and LISREL 8 for descriptive statistics, correlation, and Regression for path analysis. The study findings are as follows. The psychometric testing of general family value scale was Cronbach's alpha = 0.78. The reliability of the family value scale with cancer children showed the reliability as Cronbach's alpha = 0.73. Demographic characteristics showing significant correlations were cancer children's age, period of illness, period after completing treatment, mother's age, mother's education level, monthly income, payment type, confidence with health professional, and severity of children's illness. The correlation coefficients among major variables showed that family stressor was positively related with family strains(r=0.33, p<.001), and negatively related with family hardiness(r=-0.21, p<.001). Family strains was negatively related with family hardiness(r= -0.41, p<.001) and family adaptation(r=-0.46, p<.001). Correlations of family hardiness was positive with family value with cancer children(r=-0.31, p<.001), and negative with general family value(r=-0.16, p<.01). Family hardiness was positively related with family adaptation(r=0.35, p<.001). The causal relationship between study variables showed that family strains predicts general family value(γ=0.12, t=2.02), family value with cancer children predicts family hardiness(γ=0.31, t=6.30), family strains predicts family hardiness(γ=-0.40, t=-7.70), family value with cancer children predicts family adaptation(γ=-0.23, t=-4.11), and family hardiness predicts family adaptation(γ=0.43, t=7.78).

  • PURPOSE: The purpose of this was to translate Patient-Rated Tennis Elbow Evaluation(PRTEE) into Korean and identify the reliability and validity of a Korean version of PRTEE. METHODS: The subjects of this study were 32 patients diagnosed with lateral epicondylitis. The subjects were surveyed using a Korean version of PRTEE three times: at the first visit, one week after, and two weeks after. This questionnaire consisted of 15 questions including 5 questions about pain and 10 questions about functions. Intraclass correlation coefficients were used to measure reliability and Cronbach's alpha coefficients were used to assess internal consistency. In addition, the validity of the survey results was examined by correlating a visual analogue scale with the outcome of holding without pain. RESULTS: Test-retest reliability of Korea version PRTEE was good total ICC= .962 (CI=.922-,982). Cronbach's alpha value for PRTEE was found to be .955 and it was statistically significant (p<.05). The positive correlation between PRTEE and VAS was moderate to high (r=.753, P=.00) and statistically significant. There was also a low significant negative correlation between PRTEE and PFG (r=-.362, P=.042). CONCLUSION: The Korean version of PRTEE had reliability and validity. Therefore, it is a useful measure to evaluate the conditions of patients with lateral epicondylitis.
