Purpose: Polycystic Ovary Syndrome Questionnaire (PCOSQ) was developed to measure health-related quality of life of women who had polycystic ovary syndrome. The purpose of this study was to exam reliability and validity of the Korean version of PCOSQ. Methods: A sample of 101 women who had polycystic ovarian syndrome was recruited from outpatient gynecology clinics. Factor analysis was carried out to verify the composition of dimensions of the Korean version of PCOSQ. Concurrent validity was examined by assessing the correlation between the PCOSQ and health related quality of life, and convergent validity was evaluated by testing correlation between PCOSQ and depression. Reliability was assessed using Cronbach's ${\alpha}$. Results: The content validitywas satisfactory (CVI=0.85). Factor analysis identified 5 factors, and factor loadings of the PCOSQ ranged from .48 to .90. Correlation was found between the PCOSQ and health related quality of life (Physical component score: r=.33, p=.001; Mental component score: r=.44, p<.001) and between the PCOSQand depression (r=-.36, p<.001). The Cronbach's ${\alpha}$ of the PCOSQ was .93, indicating reliable reliability. Conclusion: These results demonstrate that the Korean version of PCOSQ is a reliable and valid instrument for evaluating Korean-speaking women with polycystic ovarian syndrome.

PURPOSE: This study examined the effects of a whole body vibration-exercise program on the muscle strength, balance, and falling efficacy of super-aged women. METHODS: Thirty participants, who are over 75 years of age, were recruited. They were assigned randomly to an experimental group (n=15), which received whole body vibration exercise, and a control group (n=15), which received an exercise program that did not include vibration. The interventions lasted for four weeks, three times a day, and 25 minutes per session. To compare the effects of the intervention, a 30-second chair stand test (CST), Korean version of Berg balance scale (K-BBS), functional reach test (FRT), timed up and go test (TUG), and Korean version of the falls efficacy scale (K-FES) was used. RESULTS: The experimental group showed a significant increase (p.<05) before and after the intervention in the chair stand test (CST), Korean version of the Berg balance scale (K-BBS), functional reach test (FRT), timed up-and-go (TUG), and Korean version of the fall efficacy scale (K-FES). Compared to the control group, the experiment group showed a more significant increase (p.<05) in the CST, K-BBS, and FRT. CONCLUSION: A whole body vibration exercise program could be suggested as an effective intervention method for muscle and balance strengthening for super-aged women.

Purpose: This study aims to test the validity and criteria-related reliability of the Korean version of the Copenhagen Psyco-social Questionnaire version II (COPSOQ-K) assessing the psychosocial working environment. Methods: The COPSOQ-K was developed through forward-backward translation techniques, and revision based on feedback from focus groups. Survey data were collected from 311 office workers who worked in one workplace. An internal consistency reliability was estimated by Cronbach's ${\alpha}$. The impacts of the COPSOQ-K scales on job satisfaction, self-rated health, stress, sleeping troubles, burnout, and sickness absence were analyzed with multiple regression model or multiple logistic regression model, adjusted age and gender using SAS version 9.3. The Pearson correlation coefficients between the COPSOQ-K scales and Korean job stress and its subdomain were identified. Results: Cronbach's ${\alpha}$ of COPSOQ-K scales was adequate or good (0.66~0.87). The major COPSOQ-K scales predict job satisfaction, self-rated health, stress, sleeping troubles burnout, and sickness absence. The major COPSOQ-K scales were correlated with Korean job stress and its subdomain. Conclusion: The COPSOQ-K scales have satisfactory reliability and criteria-related validity. The COPSOQ-K scales will be useful for the future studies and practices associated with psychosocial working environment.

Characteristics of Superior Children as a Screening Test of Gifted students The purpose of this study was to investigate the usefulness of Korean version of checklist for behavioral characteristics of superior children as a screening test for gifted students. Total 397 children were tested KEDI-WISC (Korean version of Wechsler Intelligence Scale for Children), and their parents or primary caretakers took the checklists for behavioral characteristics of superior children individually. Total subjects were divided into 3 groups based on their Full IQ score of KEDI-WICS. The children of IQ 130 and over was gifted group, and those of IQ 115-130 was superior group, and those of below IQ 115 was average group. The analyses of behavioral checklist scores among the groups, gender, grades differences and item analysis of behavioral checklist were done for the purpose of discrimination among 3 groups. As a result, it was found that the Korean version of checklist for behavioral characteristics of superior children was very useful as a screening test for gifted correlations between checklist scores and verbal, performance and full IQ scores were significantly high, which means that IQ and checklist scores were very related. Twenty out of 50 items were found to be discrimination items between gifted and superior group. However, there was no significant difference between grades and gender on the checklist score.

It is important to examine patients' subjective evaluation as well as objective measures and clinician's rating to assess voice disorders. This study aimed to evaluate validity and reliability of Korean-version of Voice Handicap Index (KVHI) and Voice-Related Quality of Life (KVQOL) with 113 adults with voice disorders and 111 normal adults. Content validity was verified by three experienced speech-language pathologists. Concurrent validity was revealed by examining the correlation among KVHI, KVQOL, and Voice Rating Scale as well as item discrimination coefficients. Total scores of KVHI and KVQOL of adults with voice disorders were significantly different from those of normal adults. Test-retest reliability and internal consistencies were significantly high in both KVHI and KVQOL. Correlations among scores of each subscale and total score were also significantly high in each tool. The study revealed that KVHI and KVQOL are suitable tools to be used in clinics and research areas in Korea, which can subjectively evaluate the effects of voice disorders on daily life as well as on quality of life.
