  • Background and Objectives The Voice Perceived Present Control scale (VPPC) has been developed to provide better insight into patients' perceived control over their thoughts or behaviors related to voice disorders. The objective of the present study was to validate the Korean VPPC (K-VPPC) by evaluating its internal consistency and reliability. Materials and Method All items of the English VPPC were translated into Korean. Content validity was analyzed through three Delphi survey rounds by an expert panel (n=44) with active clinical and research experience in treating dysphonic patients. Twenty-three patients with a heterogeneous diagnosis of dysphonia and twenty-three gender-matched vocally normal controls (total n=46) were asked to complete the K-VPPC and the Korean Voice Handicap Index-10 (KVHI-10). Psychometric properties including internal consistency and reliability were evaluated to examine the appropriateness of cross-cultural use of K-VPPC. Results Cronbach's alpha coefficient of K-VPPC was 0.89 for dysphonic patients, indicating good internal consistency in clinical samples. Furthermore, patients with dysphonia scored significantly lower on the total score of K-VPPC and higher on voice handicap than the vocally normal controls. Spearman's correlation coefficients indicated an inverse and moderate association between the K-VPPC and all domains of KVHI-10 (Spearman's r=-0.44- -0.68). Conclusion The findings of the current study indicated that the K-VPPC is a valid and reliable tool for the assessment of perceived control in Korean patients with dysphonia. Therefore, the K-VPPC could be a useful and complementary tool for the comprehensive evaluation of dysphonia, thereby improving care in Korean patients with voice disorders.

  • Purpose: This study was conducted to evaluate the validity and reliability of the Korean version of the Sexuality Attitudes and Beliefs Survey (SABS) and to assess SABS for Korean nurses. Methods: The Korean version of SABS was developed through forward-backward translation techniques. Internal consistency reliability and construct validity using confirmatory factor analysis were conducted using PASW+ PC Win (18.0) and AMOS (18.0). Data were collected from 567 nurses who worked in one of six general hospitals across the country. Results: The Korean version of SABS showed a reliable internal consistency with Cronbach's ${\alpha}$ of subscales ranging from .59 to .73. Factor loadings of the 10 items of three subscales ranged from .38 to .83. The three subscales model were validated by confirmatory factor analysis (GFI>.97, RMSEA<.05). Sexuality attitudes and beliefs for Korean nurses were more negative than that of European or American nurses. The SABS scores for Korean nurses were significantly different according to age, marriage, education, clinical experiences, and feeling about sexuality. Conclusion: The Korean version of SABS has satisfactory construct validity and reliability to measure Korean nurses' attitudes and belief toward sexuality. Education is essential to enhance importance and self-efficacy and to relieve barriers to addressing patients' sexuality.

  • The aims of this study were to evaluate the reliability and validity of the cold and heat pattern identification questionnaire (CHPIQ). From July 2015 to December 2015, 120 participants, university faculties, filled out CHPIQ by the way of self-reporting. Then two Korean medical doctors independently diagnosed them whether they belonged to cold pattern (CP) or not, and heat pattern (HP) or not. We evaluated the internal consistency using Cronbach's alpha coefficient, and the validity using the sensitivity and specificity through receiver operating characteristic-curve. The internal consistency (Cronbach's alpha coefficient) showed 0.754 (CP) and 0.753 (HP). The area under the curve was recorded with 0.884 (CP) and 0.786 (HP). The agreements between CHPIQ and experts were 82.8% (CP) and 72.9% (HP). The sensitivities showed 0.707 (CP) and 0.719 (HP), and the specificities were 0.935 (CP) and 0.736 (HP). This study suggests that CHPIQ is a reliable and valid instrument for estimating cold-heat pattern identification.

  • Purpose: The purpose of this study was to investigate the validity and reliability of the Korean Version of the Grit (Grit-K) scale for nursing students in Korea. Methods: The participants in the study were 277 nursing students. Their grit was verified by using self-reports and the results of a questionnaire. Grit was translated into Korean and its content validity was verified by five experts. The validity of the instrument was verified through item analysis, exploratory factor analysis, and confirmatory factor analysis. Reliability verification was analyzed by using internal consistency reliability. Results: Two factors were identified through exploratory factor analysis and six items of the original instrument were found to be valid. In the confirmatory factor analysis, the validity of the instrument was verified as the model. The internal consistency reliability was also acceptable and Grit was found to be an applicable instrument. Conclusion: This study shows that the Korean Version of the Grit Questionnaire is a valid and reliable instrument to assess nursing students in Korea.

  • Objectives: This study evaluated the psychometric properties of the Korean version of the attention-deficit/hyperactivity disorder (ADHD) Stigma Questionnaire (ASQ) and the effect of the source of information about mental health on ADHD stigma. Methods: The Korean translation of the ASQ was prepared, and 673 participants, 20-64 years of age, completed the questionnaire using an online panel survey in South Korea. The participants also completed questionnaires detailing sociodemographic variables and the source of their mental health knowledge. Cronbach's alpha coefficient was used to explore the internal consistency of the ASQ. Factor analysis using Varimax rotation was conducted to investigate the structure of the ASQ. Results: The 26-item ASQ demonstrated excellent internal consistency (Cronbach's alpha=0.940). Factor analysis supported a three-factor structure, including Concerns with Public Attitudes, Negative Self-Image, and Disclosure Concerns. There were no significant differences in the total ASQ scores according to sociodemographic characteristics. Participants who reported the internet as their major source of information about mental health showed higher ASQ scores compared to those who used other sources for mental health information. Conclusion: The Korean translation of the ASQ has acceptable psychometric properties among Korean adults. Inaccurate information from the internet could increase the stigma toward ADHD.

  • Purpose: The purpose of this study was to develop an instrument for measuring sexual values of college students. Methods: The data were collected from 308 university students for three months from March 15th to June 15th, 2016. The development of the scale was done in the following order: development of preliminary items; verification of content validity and reliability; factor analysis; and criterion validity of final items. Results: We developed a questionnaire using a five-point Likert-type scale in a self-report form containing 18 items. From the factor analysis, 18 items in three factors were finalized. The 18 items included 3 sub-scales: Cognitive (5 items); Affective (4 items); and Behavioral (9 items). The internal consistency was acceptable (Cronbach's ${\alpha}=.88$). In this study, sexual values were significantly correlated with self-concept (r=.344, p<.001). Conclusion: The results of this study will be useful not only for evaluating sexual values of college students but also for obtaining basic data for sex education. However, we need further studies in order to use the scale in practice and research.

  • This study aimed to develop a reliable and valid developmental test for toddlers and preschoolers. A trial form of the test with 230 items in 5 domains(cognitive, physical, language, social, and self-help) was constructed and administered to 200 children from 2 to 5-year-olds. Item analysis indicated that most items selected in cognitive, physical, and indicated domain were acceptable in terms of item response rate and item discrimination. However, some items in social and self-help domain did not show clear age trends in item response, but mostly were adequate in item discrimination. Based on item analysis, 112 items were selected for the final form : 24 items each for the cognitive, physical, and language domain; 20 items each for the social and self-help domain. Reliability indicated by internal consistency coefficients(KR-20) were high in all domains. Validity of the test was supported by inter-correlations among 5 domains(.61 to .93), and significant age differences in domain scores.
