Purpose: This study was to conduct a Korean cultural adaptation of the WHO disability assessment schedule (WHODAS) 2.0: 36-item version. Methods: An internationally standardized process of translation and cultural adaptation of an instrument was used to develop a Korean version of WHODAS 2.0: 36-item version. Linking each item into the International Classification of Functioning, Disability and Health (ICF) was also conducted in order to ensure the concepts in the translated instrument were compatible with ICF. All translated versions of the instrument, linking results and feedback from participants were used for the final adaptation of the Korean version of the instrument. The Korean version of the instrument was assessed twice on different occasions to examine Inter- and intra-rater reliability, and the intra-class correlation coefficient (ICC) was calculated. Results: Twelve participants were involved in the translation and linking process. Ninety-five volunteers were invited to participate to examine the reliability of the instrument. Fifty participants completed the self-rated version of the instrument and 45 finished the interviewer version. The Korean WHODAS 2.0: 36-item version was found to have excellent reliability: self-rated version and interviewer version reliability coefficients were ICC=0.92 and ICC=0.94, respectively. Thirty-four items of the translated instrument were to be linked to ICF categories. Some adaptation was made; details and a familiar example were added to help respondents answer the questions. Conclusion: The study results show that the adaptation of the 36-item version of WHODAS 2.0 to Korean was successful and the instrument is ready for use in testing its psychometric properties.

Objective: In this study, we examined the psychometric properties of the Korean Intergenerational Psychological Ambivalence Scale (KIPAS) for young adult children. Method: Data came from 1,140 Korean young adults aged 19-34, who were never married and had at least one living parent. We translated the individual-subjective dimension of Zygowicz's (2006) Intergenerational Ambivalence Scale from English to Korean. The individual-subjective dimension had eight items that directly measured intergenerational psychological ambivalence (D-KIPAS) and 10 items that indirectly measured intergenerational psychological ambivalence (I-KIPAS). Results: The D-KIPAS and I-KIPAS items showed good internal consistency both for the mother and the father. Confirmatory factor analysis showed that D-KIPAS items loaded on one factor after controlling for method effects, which allowed error variances among the four non-reversed items to covary. Both the positive and negative items of I-KIPAS had good reliability and loaded on the same factor. The mean score of D-KIPAS and the calculated score of I-KIPAS were significantly but moderately correlated, which indicates that the D-KIPAS and I-KIPAS assess correlated but distinct aspects of intergenerational ambivalence. Correlations among D-KIPAS, I-KIPAS, and the proxy variables of intergenerational solidarity and conflict supported the discriminant validity of the KIPAS. Conclusion: The results of this study suggest that both D-KIPAS and I-KIPAS are reliable and valid tools to measure intergenerational psychological ambivalence among Korean young adults.

Background: Respiratory masks can provide healthcare workers with protection from biological hazards when they have good performance. There is a direct relationship between the visual specifications of a mask and its efficacy; thus, the aim of this study was to develop tools for qualitative assessment of the performance of masks used by healthcare workers. Methods: A mixed-methods design was used to develop a qualitative assessment tool for medical face masks (MFM) and particle filtering half masks (PFHM). The development of domains and items was undertaken using observation and interviews, the opinions of an expert panel, and a review of texts and international standards. The second phase evaluated the psychometric properties of tools. Finally, the validated Mask Qualitative Assessment Tools (MQAT) were used to assess six samples from 10 brands of the two types of masks. Results: MQAT-MFM and MQAT-PHFM shared 42 items across seven domains: "cleanliness," "design," "marking, labeling and packaging," "mask layers," "mask strap," "materials and construction," and "nose clip." MQAT-MFM included one additional item. MQAT-PHFM included another nine items associated with an eighth "Practical Performance" domain, and the valve version had another additional "Exhalation Valve" domain and six items. The evaluation indicated 80% compliance for MFM and 71% compliance for PFHM. "Marking, labeling and packaging" and "Layers" were associated with the least compliance in both types of masks and should be checked carefully for defining mask quality. Conclusion: MQAT can be used for immediate screening and initial assessment of MFM and PHFM through appearance, simple tools, and visual inspection.

Background: The high incidence of work-related diseases and injuries among day-laborers and workers with no legal contracts (informal workers) has received the attention of the Thai authorities. Workers' low occupational health literacy (OHL) has been reasoned as one contributing factor. Absence of a valid tool has prevented assessment of informal workers' OHL. The aim of this study was to create a valid and reliable Occupational Health Literacy Scale within the context of Thai working culture (TOHLS-IF). Methods: This study used the mixed method approach to develop TOHLS-IF. Questions were generated using in-depth interviews and an extensive review of the literature. Experts' assessment confirmed the content validity of TOHLS-IF. The scales of its psychometric properties were assessed in a sample of 400 informal workers using cluster random sampling. Results: The final version of the TOHLS-IF comprises 38 items within 4 dimensions: Ability to Gain Access, Understanding, Evaluation, and Use of occupational health and safety information. Factor analysis identified items explaining 50.22% of the total variance. The final confirmatory analysis confirmed the model estimates were satisfactory for the construct. TOHLS-IF demonstrated a high internal consistency and satisfactory reliability (Cronbach's alpha = .98). Conclusion: The TOHLS-IF is a valid and reliable instrument to assess informal workers' OHL. The structural dimensions of this instrument are based on the concept of health literacy and Thai culture. Thai health professionals are encouraged to benefit from this instrument to assess their workers' OHL and apply findings as guidelines for effective occupational health and safety interventions.

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.

This scoping review aimed to identify and categorize the available measurement options for vaginal laxity (VL), their indications of use, and whether these measurements can sufficiently provide objective clinical judgment for cases indicated for vaginal rejuvenation with many treatment options nowadays. Systematic searches were conducted on five electronic databases, manually searching articles' bibliographies and predetermined key journals with no date or study design limitations. We included all studies involving VL in their inclusion criteria, treatment indications, and outcome parameters. We used the Arksey and O'Malley frameworks as the guideline in writing this scoping review. Of the 9,464 articles identified, 66 articles and 11,258 subjects were included in the final analysis. The majority of studies were conducted in obstetrics and gynecology (73%), followed by plastic surgery (10%), medical rehabilitation (4.5%), dermatology (4.5%), and others (8%). Most studies originated from the North American region (30%). The following measurement tools were used: (1) interviews, (2) questionnaires, (3) physical/digital examinations, (4) perineometers, and (5) others. Our results suggested that subjective perception of laxity confirmed by directed interview or questionnaire is sufficient to confirm VL. Additional evaluation of pelvic floor muscle through digital examination or perineometer or other preferred tools and evaluation of sexual function through validated questionnaire (Female Sexual Function Index, Female Sexual Distress Scale-Revised, etc.) should follow to ensure holistic care to patients. Future research on the psychometric properties (reliability and validity) of commonly used measurements and the correlation in between subjective and objective measurements should be initiated before their clinical applications.

그동안 공감이 대인관계에서 하는 역할은 꾸준히 밝혀져 왔다. 하지만 공감이 주관적 안녕감에 어떤 영향을 미치는지 밝히는 연구는 거의 없었다. 이에 따라 본 연구에서는 공감이 자기존중감을 매개로 주관적 안녕감에 영향을 미친다는 모형을 가정하고 검정하고자 하였다. 또한 허재홍, 이찬종 (2010)은 공감지수 (Empathy Quotient: EQ) 척도의 심리측정 속성은 밝혔으나 확인요인분석은 하지 않아 본 연구에서 확인요인분석을 하였다. 대학생 421명 (남학생 192명, 여학생 225명)을 대상으로 설문을 실시하였고, 구조방정식 모형과 경로분석을 하였다. 연구결과 EQ는 기존 연구와 마찬가지로 세 요인 (인지공감, 정서공감, 사회기술공감)으로 보는 것이 타당하였다. 또한 공감은 자기존중감을 매개로 주관적 안녕감에 영향을 미치고 있었다. 이 연구 결과에서 공감이 우리나라 문화에서 개인이 문화의 가치를 충족시킴으로써 자기존중감을 높이고 이는 다시 주관적 안녕감을 향상시킨다는 것을 알 수 있었다. 이와 함께 본 연구에서는 공감에 우리나라 문화 특성도 반영해야 한다는 사실도 시사되었다.

Objectives There are only a limited number of studies on instruments assessing fatigue in university students, although fatigue exerts negative influences on their health and academic performances and fatigue-related complaints are more frequently reported in young adults than middle-aged adults. The aim of this study was to validate the 9-item Fatigue Severity Scale (FSS) among university students including both undergraduate and graduate students in South Korea. Methods A total of 176 university students completed a battery of self-report questionnaires, including the FSS, the Brief Fatigue Inventory (BFI), the Beck Depression Inventory-II (BDI-II), the Beck Anxiety Inventory (BAI), the Medical Outcomes Study Short Form 36 version 2 (MOS-SF36v2), and the Inclusion of Community in the Self Scale (ICS). The data were collected from February of 2012 to June of 2012. The reliability, convergent validity, divergent validity, and exploratory factor analyses were conducted to assess psychometric properties of the FSS. Results The mean FSS score was 3.20 (standard deviation = 1.43). The FSS demonstrated an excellent internal consistency (Cronbach's ${\alpha}$ = 0.93) and item-total correlations ranged from 0.56 to 0.90. Correlations of the FSS with the BFI (r = 0.71, p < 0.01), BDI-II (r = 0.54, p < 0.01), BAI (r = 0.46, p < 0.01), MOS-SF36v2 physical component summary (r = -0.28, p < 0.01), MOS-SF36v2 mental component summary (r = -0.55, p < 0.01), and ICS (Spearman's rho = -0.07, p = 0.33) showed acceptable convergent and divergent validity. Exploratory factor analysis defined one underlying factor (eigenvalue = 5.67) that explained 93.50% of the total variance. Conclusions To the best of our knowledge, this is the first study to investigate reliability and validity of the FSS in university students. The FSS exhibits good psychometric properties for evaluation of fatigue among university students in South Korea. Since the FSS is easy to administer, score, and interpret, it could be a useful tool in research and practice for assessing fatigue among university students.
