  • Purpose: This study was conducted in order to evaluate the reliability, validity, sensitivity, and specificity of the Short Form of Bobath Memorial Hospital Fall Risk Assessment Scale (BMFRAS-SF). Methods: A validation study was conducted on 207 elderly patients aged over 65 who were admitted to Bobath Memorial Hospital. Fall risk scores of BMFRAS, composed of eight subscales (age, fall history, physical activity, consciousness level, communication, fall risk factors, underlying disease, and medications) were assessed from the electronic medical record. BMFRAS-SF was derived from eight subscales of the BMFRAS representing the significance between fallers and non-fallers (fall history, physical activity, fall risk factors, underlying disease, and medications). Internal consistency reliability and interrater reliability were assessed by Cronbach's alpha and kappa coefficient. Validity was assessed by Spearman correlation analysis, factor analysis. Sensitivity, specificity, positive predictive and negative predictive values, and a receiver-operating characteristic curve (ROC) were generated. Results: Fallers had significantly higher risk scores than non-fallers in fall history, physical activity, fall risk factors, underlying disease, and medication scales. The BMFRAS-SF demonstrated acceptable Cronbach's alpha (.706) and kappa coefficients of .95. The BMFRAS-SF subscales showed good convergent validity and construct validity. The BMFRAS-SF presented good sensitivity(86.7%), specificity(67.9%), positive predictive value(42.9%) and good negative predictive value(94.8%) at a cut-off score of 5. Areas under the ROC curves were .860 for the BMFRAS and .861 for the BMFRAS-SF. Conclusion: The BMFRAS-SF was proved to be reliable and valid. It could be used for time-saving assessment and evaluation of the high risks for falls in clinical practice settings.

  • Objectives : The Alcohol Urge Questionnaire(AUQ) has been used in alcohol dependence treatment and research. The goal of this study is to develop of the Korean Alcohol Urge Questionnaire(AUQ-K). Methods : To examine the AUQ-K's psychometric properties, responses from 104 patients admitted in alcohol dependence treatment facility were investigated. Results : The internal consistency of the 8-item AUQ-K, measured by coefficient ${\alpha}$, was high(Cronbach's ${\alpha}$=0.78). AUQ-K scores showed significant correlation when the retest interval was 1 day(p<0.01). The AUQ-K's validity was investigated using correlational analyses with two other craving scales[the Obsessive Compulsive Drinking Scale(OCDS) and the Visual Analogue Scale(VAS)]. The high correlations were obtained between total AUQ-K scores and total OCDS scores, and between total AUQ-K scores and the VAS scores(p<0.01, respectively). Conclusion : The AUQ-K is a reliable and valid short scale for measurement of self-reported alcohol craving. This scale may offer significant advantages over existing single-item measures of alcohol craving in the fields of alcohol dependence treatment and research.

  • The study was performed to determine the reliability and validity of the 'Qi Blood Yin Yang Deficiency Questionnaire (Qi Blood Yin Yang DQ)' for the 100 subjects with chronic fatigue. After 100 subjects respond to the 'Qi Blood Yin Yang DQ', Korean medical doctor classified the subjects into 4 groups such as Qi deficiency group, Blood deficiency group, Yin deficiency group and Yang deficiency group. 100 subjects were retested in the same way after 3 weeks. The reliability and the validity of the questionnaire were inspected. Internal consistency of the 'Qi Blood Yin Yang DQ' was excellent (Cronbach alpha 0.916). Test-retest reliability was good (intra-class correlation coefficient 0.699). Construct validity analyzed by exploratory factor analysis produced 4 factors, which were selected from eigenvalues that are greater than 1.0. The 'Qi Blood Yin Yang DQ' consisted of 4 factors. The factor 1, 2, 3 and 4 showed 'Qi deficiency', 'Yin deficiency', 'Yang deficiency' and 'Blood deficiency' respectively. The 'Qi Blood Yin Yang DQ' restructured in this study may provide a fundamental questionnaire and a further study is required for a more advanced, standardized and statistically proven questionnaire.

  • Purpose: The purpose of this study was the development and validation of knowledge scale for patients with breast cancer (KS-Br) in Korea. Methods: The process included the construction of a conceptual framework, generation of preliminary items, and the test of validity and reliability of the scale. Thirty-seven items were developed through an evaluation process by 10 experts and 24 items were finally confirmed through item analysis. Psychometric testing was performed with a convenient sample of 303 women with breast cancer. The data was analyzed using independent t-test, Pearson's correlation, and calculation of KR-20. Results: Participants averaged 70.8% correct on the test. The KS-Br has 24 items consisting of 5 categories: incidence of breast cancer, diagnosis and treatment, symptom management, sexuality, and maintenance of daily life. Validity was supported by the use of content validity, known-group technique, and criterion-related validity. Women who had undergone education intervention scored significantly higher than women who had not (p<.001). KS-Br scores were significantly correlated with those of Mishel's Illness Uncertainty Scale (r=-.214, p<.001). Internal consistency of the KS-Br was appropriate (KR20=.805). Conclusion: This study reveals that the KS-Br is reliable and valid scale to measure the knowledge of breast cancer. Therefore, this scale can be effectively utilized to assess the knowledge of patients with breast cancer regarding their disease.

  • Devices to measure the blood pressure of patients are being used without any calibration in a hospital. It is an important to show consistent values when any medical devices measure the same patients regardless they are sphygmomanometer or fully automatic electronic blood pressure meter. We compared sphygmomanometer and fully automatic electronic blood pressure meters with standard digital blood pressure monitor (SDBPM) to evaluate the consistency of the small healthy subjects. We measured the blood pressure from six healthy subjects (three of 20~40 years and three of 40~60 years old). Two sphygmomanometer and two fully automatic electronic blood pressure meters were used and compared with the SDBPM. Blood pressures measured from right and left arms each and were compared. All six healthy subjects showed normal blood pressure values. In general, left blood pressure values showed higher values than right side. Comparing SDBPM, with the other monitors, the systolic pressure showed ${\pm}$ 34.8% difference and ${\pm}$ 33.3% for the diastolic pressure. Correlation between SDBPM and Sphygmomanometer was 0.59~0.71, and 0.50~0.70 for fully automated digital BP monitors. It fell in grade-D when we apply the BHS(British hypertension society). AAMI(American association for the advancement of medical instrumentation) also showed unsatisfactory results for the mean value (${\leq}$ 5 mmHg) and standard deviation (${\leq}$ 8 mmHg). We tested sphygmomanometer and fully automatic electronic blood pressure meters and compared with a standard digital blood pressure monitor. All devices showed inconsistent blood pressures. A reliable calibration system is highly needed for all devices in all hospitals.

  • The purpose of this study is to conduct the Korean translation and validity of the Unconditional Positive Self-Regard Scale(UPSR) that Patterson and Joseph(2006) originally developed based on the Rogerian person-centered theory. K-UPSR was adapted, modified and validated from the UPSR Scale. This study verified reliability and validity, and factor structure of K-UPSR. The preliminary study was proceeded with twelve adapted questions to 131 undergraduate and graduate students. As a result, three questions were deleted for the low reliability. The exploratory factor analysis of the nine questions showed two sub factors. The internal consistency reliability of nine questions with two sub factors was .89 in this study. The study was conducted by 419 male and female adults and verified confirmatory factor analysis and the validity. The study data was evaluated for the suitability of convergent and discriminant validity of K-UPSR. Through the correlation analysis of other five scales, the result was mostly corresponded to the preliminary study.

  • In this study, the drought indicator is calculate from the rainfall, daily highest temperature, streamflow and Palmer Drought Severity Index(PDSI) for water plan and drought management in a relatively wide region. Three levels of drought severity, called drought watch, drought warning, and drought emergency, are established for these series which determine exceedance levels. The 25% nonexceedance level is used for drought watch, 10% for drought warning, and 5% for drought emergency to figure how well the drought indicators represent the past-drought and that those can be used for drought monitoring. As a result, 9-month and 12-month precipitation, and PDSI series shows the best consistency and high correlation indicate droughts. Because the results are based on the gauged data and simply calculated, the suggested indices can be used for basic data for drought monitoring system of a basin.

  • The purpose of this study was to define the relationship between the leadership style of head nurses and the burnout level of nurses by taking into consideration the factors which influence the level of burnout and which show how burnout varies according to the leadership style of lead nurses. The subjects of the survey were 355 ward nurses and their 48 head nurses working in five university hospitals in Seoul. The nurses were surveyed by means of a questionnaire from Sept. 22 though Sept. 29, 1983. The Leadership Scale devised by Fleishman, and modified by Lee, and the Burnout Scale developed by Pines et al, and adapted to the Korean situation by Peek, were used as a basis of ;his survey This researcher subjected the questionnaire to a pre-test and to an internal reliability consistency test through item analysis. For the purpose of analysis of the data, the general characteristics were set at Mean and the general characteristics of head nurses in relation to the level of burnout of nurses was analysed by the Pearson Correlation Coefficient. The relation between head nurses' general characteristics 3nd leadership style, the relation between nurses' general characteristics and level of burnout and the level of burnout of nurses according to the different style of leadership of head nurses were analysed by ANOVA. A summary of the results of the study is as follows. 1. Hypothesis:“That the burnout level of the nurse will be different according to the leadership style of the head nurse”was supported. 2. Analysis of the relationship between the head nurse's general characteristics and the leadership style of the head nurse showed that the leadership style of the head nurse was not related to age and experience as head nurse. 3. Analysis of the relationship of nurses' burnout levels to general characteristics of nurses showed statistically significant differences in burnout levels according to working departments, expected working period and reasons for selecting nursing as a profession. Also, the burnout level of nurses was negatively related to the head nurse's age and experience as a head nurse.

  • Background: Body image dissatisfaction among breast cancer survivors has been associated with psychological stress resultant from breast cancer and resultant surgery. This study aimed to examine the psychometric properties of the Malay Version of the Breast-Impact of Treatment Scale (MVBITS) and to investigate the associations of retained factors with the Hospital Anxiety and Depression Scale (HADS) and the Rosenberg Self-Esteem Scale (RSES). Materials and Methods: The MVBITS was 'forward-backward' translated from English to Malay and then administered to 70 female breast cancer patients who came to the Oncology Clinic of University Malaya Medical Centre, Kuala Lumpur, Malaysia to undergo chemotherapy. Principal component analysis (PCA) with varimax rotation was performed to explore the factor structure of the MVBITS. Associations of retained factors were estimated with reference to Spearman correlation coefficients. Results: The internal consistency reliability of MVBITS was good (Cronbach's alpha 0.945) and showed temporal stability over a 3-week period. Principal component analysis suggested two factors termed as 'Intrusion' and 'Avoidance' domains. These factors explained 70.3% of the variance. Factor 1 comprised the effects of breast cancer treatment on the emotion and thought, while Factor 2 informed attempts to limit exposure of the body to self or others. The Factor 1 of MVBITS was positively correlated with total, depression and anxiety sub-scores of HADS. Factor 2 was positively correlated with total and anxiety sub-scores of HADS. MVBITS was also positively correlated with the RSES scores. Conclusions: The results showed that the Malay Version of Breast-Impact of Treatment Scale possesses satisfactory psychometric properties suggesting that this instrument is appropriate for assessment of body change stress among female breast cancer patients in Malaysia.
