Objective: To prevent low back pain, an objective evaluation tool to evaluate pelvic mobility and exercise to improve the flexibility of the lumbar region is needed. The purpose of this study was to compare the results of pelvic mobility measurements using the Wii Balance Board (WBB) and Sensbalance Therapy Cushion (STC), evaluate the usefulness of the STC as a tool for measuring pelvic mobility. Design: Cross-sectional study. Methods: Fifty healthy subjects participated in this study. The subjects performed pelvic mobility range, proprioception, reaction time and reach of the arm using the STC. The pelvic movement parameter was measured two times to determine the intra-rater reliability. To measure the correlation between lumbar muscle tension and pelvic mobility, Myovision was used to measure tension of L4, L5 level erector spinae muscle. Correlations between measured variables were checked to determine the validity of the pelvic mobility assessment tool. Results: STC showed high test-retest reliability in pelvic tilt measurement and reaching task [intraclass correlation coefficients (3,1)=0.804-0.915]. The relationship between WBB and STC showed a significant positive correlation with the pelvic tilt and reaching task (p<0.05). Posterior tilt and erector spinae activation (Lt. L5) showed a significant negative correlation (p<0.05). Left, right tilt and erector spinae activation (L5) showed a significant negative correlation (p<0.05). Conclusions: This study confirmed the advantages of the STC and found efficiency as an objective measuring device of pelvic mobility.

This study was designed to develop a teacher's rating scale of elementary school student's school maladjustment. 50 behavior were drawn as elementary school student's school maladjustment behavior from the responses of elementary school teachers. To identify sub-factors of the scale, 60 teachers rated their 240 student's behavior and the collected data were analyzed by using factor analysis. 4 sub-factors were identified as the result : aggressive selfish behavior, misconduct of lesson and classroom rules, passive unsociable behavior and positive evasion of school activities. To identify the validity of the scale, the data from 120 students were analyzed through the concurrent validity between the scale and the teacher rating scale of school maladjustment for Student Problem Behavior Checklist for Elementary School students(Kim & Hwang, 2009). To examine the reliability of the scale, test-retest correlations were calculated by using the data from 120 students and internal consistency coefficients were calculated by using the data from 120 students. The results showed that Teacher's rating Scale of Elementary School Student's School Maladjustment was valid and reliable.

This paper describes the development of Korean version of two widely used self-report measure of alexithymia-Schalling-Sifneos Personality Scale (SSPS) and Toronto Alexithymia Scale(TAS), and present the preliminary results of their reliability and validity tested to an Korean college student sample(N=206). TAS showed moderate to acceptable internal consistancy with 0.26 of mean item-total correlation and 0.754 of Cronbach's alpha coefficient, while those parameters for SSPS turned out inconsistent. However, results of test-retest reliability for both scale were excellent. Factor analysis revealed tow factors for TAS and three factors for SSPS ; the four-factor structure of TAS was quite congruent with previously known alexithymaia construct, while, again, SSPS showed intermixed factor structure. TAS scores correlated fairly well with somatization scores enough to get concurrent validity while SSPS scores did not. Overall, Korean version of TAS demonstrated well matched findings in terms of internal consistency and factorial validity with original and Spanish version of TAS. The results suggest that Korean version of TAS could be a useful and reliable tool for the measurement in Korean population.

Background: Workplace bulling is a pervasive phenomenon with negative consequences for the health of victims and the productivity of organizations. The aim of this study was to measure the prevalence and forms of workplace bullying among employees working at the public health-care sector of Cyprus using the Greek version of Leymann Inventory of Psychological Terror (LIPT) instrument. Methods: A translation process was followed from the French to the Greek version of LIPT questionnaire. Test-retest reliability expressed by Pearson's correlation coefficient was 0.98 indicating excellent reproducibility. Internal consistency reliability assessed by Cronbach ${\alpha}$ coefficient was 0.87 suggesting high reliability. LIPT instrument was distributed among 403 employees working at the primary health-care setting and at the largest public hospital of Cyprus with response rate of 73.4%. Results: Women comprised the majority of participants (71.4%). Mean age was 43.3 years. Prevalence of workplace bulling according to Leymann's definition was 5.9%. Most common forms of bullying were "Being continuously interrupted" (17.2%) and "continuously being given new work assignments" (13.5%). Women were significantly more often exposed to at least one mobbing behavior than men within the previous year (49% vs. 35.7%, p = 0.038), whereas nurses were significantly exposed to at least one mobbing behavior as compared to physicians (53.3% vs. 31.4%, p = 0.004). Conclusion: This was the first study that examined the prevalence of workplace bullying in the public health-care sector by elaborating the Greek version of LIPT instrument. Results showed that workplace bullying is a common and complex phenomenon among health-care organizations.

Objectives : We examined the reliability and validity of the Korean version of the Depression and Somatic Symptom Scale (DSSS) in Korean patients with depressive symptoms. Methods : Participants were 55 outpatients diagnosed with major depressive disorder, a depressive episode of bipolar I disorder, somatoform disorder, panic disorder, generalized anxiety disorder, or post-traumatic stress disorder according to the DSM-IV criteria. We assessed them using the Korean versions of the DSSS, Hamilton Depression Rating Scale (HDRS), and Quick Inventory of Depressive Symptomatology Self Report (QIDS-SR). Results : The Korean version DSSS had a Cronbach's alpha of 0.90. Moreover, each item's correlation with the total score was statistically significant (r=0.24-0.71, p<0.01). The test-retest correlation coefficient (r=0.83, p<0.01) was relatively high, and the DSSS correlations with the HDRS and QIDS-SR were 0.77 and 0.74, respectively. Conclusion : These results demonstrate that the Korean version of the DSSS could be a reliable and valid tool for screening and assessing depressive patients. The Korean version of the DSSS will be a useful tool for screening both depressive and somatic symptoms in Korea.

Background/Aims There is uncertainty about how to measure outcomes reported by patients in gastroesophageal reflux disease (GERD). This study was conducted to develop an instrument and to determine of the definition of respondent for a patient reported outcomes to assess the efficacy of a treatment used for GERD treatment. Methods A structural process has developed a self-evaluation questionnaire for GERD (SEQ-GERD); health-related quality of life questionnaire for GERD (GERD-QOL) was translated through cross-cultural validation. Two-week reproducibility was evaluated and construct validity was assessed by correlating the SEQ-GERD with the Patient Assessment of Gastrointestinal Disorders (PAGI-SYM), the reflux disease questionnaire (RDQ), and GERD-QOL. Changes in SEQ-GERD scores were compared to assess the discriminative validity following 4 weeks of proton pump inhibitor administration. Results A total of 83 Korean patients were included (mean age $46{\pm}14$ years, females 61.4%). The internal consistency of the 19-item SEQ-GERD was good (alpha = 0.60-0.94) and the test-retest reliability was high (intra-class correlation coefficient = 0.67-0.95). The SEQ-GERD highly correlated with the GERD domain of the PAGI-SYM (correlation coefficient r = 0.894, P < 0.001), the RDQ-GERD (r = 0.877, P < 0.001), and GERD-QOL (r = -0.536, P < 0.05). SEQ-GERD scores significantly varied according to the overall treatment effectiveness scale of drug responsiveness and significantly decreased after drug treatment (mean differences according to the overall treatment effectiveness scale, P = 0.020). Conclusion This study supports that SEQ-GERD is reliable and valid, and can be used to evaluate the treatment response in patients with GERD.

Purpose: The aim of this study was to evaluate the validity and reliability of the Korean version of Short-form Health Literacy Scale (HLS-SF-K12) for Adults. Methods: The English HLS-SF12 was translated into Korean with forward and backward translation. Survey data were collected from 204 adults who visited two hospitals in Korea. Content validity, construct validity, and known-groups validity were evaluated. Cronbach's α for internal consistency and test-retest were used to assess reliability. SPSS 21.0 and AMOS 21.0 software were used for data analysis. Results: The HLS-SF-K12 was composed of 12 items, and three subscales (health care, disease prevention, and health promotion). The instrument explained reliable internal consistency with Cronbach's α for the total scale of .89, and .74~.81 for subscales. The model of three subscales for the HLS-SF-K12 was validated by confirmatory factor analysis (Normed χ2=2.14 (p<.001), GFI=.92, RMR=.04, RMSEA=.08, CFI=.94, TLI=.92, IFI=.94). The hypothesis testing which analyzed the differences in health literacy by age and education level was satisfied. Conclusion: The HLS-SF-K12 is a valid and reliable instrument for measuring health information comprehension for adults in Korea.
