Objectives: This study aimed to adapt the survey questionnaire designed by Moens et al. (2021) and determine the validity and reliability of the Arabic version of the survey in a sample of the Saudi population experiencing teleworking. Methods: The questionnaire includes 2 sections. The first consists of 13 items measuring the impact of extended telework during the coronavirus disease 2019 (COVID-19) crisis. The second section includes 6 items measuring the impact of the COVID-19 crisis on selfview of telework and digital meetings. The survey instrument was translated based on the guidelines for the cultural adaptation of self-administrated measures. Results: The reliability of the questionnaire responses was measured by Cronbach's alpha. The construct validity was checked through exploratory factor analysis followed by confirmatory factor analysis (CFA) to further assess the factor structure. CFA revealed that the model had excellent fit (root mean square error of approximation, 0.00; comparative fit index, 1.0; Tucker-Lewis index, 1; standardized root mean squared residual, 0.0). Conclusions: The Arabic version of the teleworking questionnaire had high reliability and good validity in assessing experiences and perceptions toward teleworking. While the validated survey examined perceptions and experiences during COVID-19, its use can be extended to capture experiences and perceptions during different crises.

Purpose: This study was performed to assess the reliability and validity of the Korean version of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Chemotherapy-induced peripheral neuropathy 20 items (EORTC QLQ-CIPN20) in patients receiving neurotoxic chemotherapy. Methods: A convenience sample of 249 Korean cancer patients, previously or currently, being treated with peripheral neurotoxic chemotherapeutic agents were asked to fill in the questionnaire. Collected data were analyzed using SPSS 21.0 and AMOS 21.0. Construct validity, known-group validity, concurrent validity, and internal consistency reliability of the Korean version of the QLQ-CIPN20 were evaluated. Results: Factor analysis confirmed 3 dimensions of CIPN: sensory, motor, and autonomic. The factor loadings of the 20 items on the 3 subscales ranged from .38 to .85. The 3 subscale-model was validated by confirmatory factor analysis (GFI=.90, AGFI=.86, RMSR=.05, NFI=.87, and CFI=.94), and concurrent validity was demonstrated with the EORTC QLQ-C30. Furthermore, the QLQ-CIPN20 established known-group validity. The Cronbach's alpha coefficients for internal consistency of the subscales ranged from .73 to .89. Conclusion: The Korean version of the EORTC QLQ-CIPN20 showed satisfactory construct, concurrent, and known-group validity, as well as internal reliability.

Purpose: This study presents a translation, cultural adaptation, and psychometric evaluation of two instruments of the Fertility Awareness and Attitudes Towards Parenthood (FAAP) questionnaire (Conditions and Life changes) for use in South Korea. Methods: This methodological study included 166 university students for psychometric evaluation in the sixth step. The first five steps included forward translation, backward translation, committee review, assessment of content validity, and a pre-test. In the sixth step, psychometric properties, including internal consistency, construct validity, and criterion validity, were evaluated. Exploratory factor analysis and confirmatory factor analysis were conducted to identify the structure of the tool and to assess its validity. Results: The Korean version showed acceptable internal consistency. Cronbach's α was .73 for FAAP-Conditions and .83 for FAAP-Life changes. FAAP-Conditions showed a four-factor structure (social conditions, relationship with partner, external environment, and child-rearing support) and FAAP-Life changes had a two-factor structure (reward and burden). In the confirmatory analysis, CMIN/DF, TLI, IFI, SRMR, CFI, and RMSEA were satisfactory. Conclusion: This study provided preliminary evidence of the acceptability, reliability, and validity of the Korean version of the FAAP questionnaire in university students in South Korea. Nonetheless, further evaluation among Korean young adults is warranted to validate this instrument.

Objectives : The aims of the current study were to assess the reliability and validity of the CoRe-Ditec-BS Questionnaire-II (BSQ-II; Blood stasis questionnaire-II) with 8 items including 5 items related women added to BSQ-I that was consisted of 36 items and developed in 2013. Methods : Between May 2014 and November 2014, 411 patients from 3 traditional Korean medical hospitals were asked to complete the BSQ-II. Each patient was independently diagnosed with BSS by two traditional Korean medical physicians from the same site. We estimated the internal consistency using Cronbach's ${\alpha}$ coefficient, the discriminant validity using the means score of BSS, and the predictive validity using logistic regression (sensitivity and specificity). Results : The BSQ-II had satisfactory internal consistency (Cronbach's ${\alpha}$ coefficient=0.765) and validity, with significant differences in the mean scores between the BSS($63.60{\pm}9.56$) and non-BSS groups($48.36{\pm}5.93$). The area under the receiver operating curve was about 98%, and the sensitivity and specificity were 91.4% and 94.9%, respectively. Conclusions : These results suggest that the CoRE-Ditec-BSQ-II is more reliable and valid instrument for estimating BSS than BSQ-I.

Objectives: This study is aimed at assessing the reliability of a standard instrument of diagnosis and assessment for Spleen Qi deficiency pattern questionnaire (SQDQ) and examining the validity of the SQDQ by comparing the pattern identification scores of different groups. Methods: We conducted a survey of 72 participants (60 patients with chronic dyspepsia and 12 healthy subjects) using self-reported questionnaire. Participants were given written consent and this study was performed under the permission of institutional review board of Kyung-Hee university Korean medicine hospital. Results: The reliability and the validity of the questionnaire were inspected. Internal consistency of the SQDQ was excellent. Construct validity analyzed by exploratory factor analysis produced 4 factors, which were selected from eigenvalues that are greater than 1.0. The factor 1, 2, 3 and 4 showed 'fatigue', 'meal', 'diagnosis' and 'figure' respectively. For most of SQDQs' items, there were significant differences observed between the Spleen Qi and the non-Spleen Qi groups. However, the 'emaciation', 'tongue diagnosis' and 'pulse diagnosis' showed no significant differences. Conclusions: The SQDQ restructured in this study may provide a fundamental questionnaire and a further study is required for a more advanced, standardized and statistically proven questionnaire.

Background: This study aimed to develop and assess the psychometric features of the Physical Activity at Workplace Questionnaire (PAWPQ) based on the Social Cognitive Theory (SCT) to evaluate employees' physical activity (PA) behaviors at the workplace. Methods: This psychometric cross-sectional study was conducted on 455 employees working in one of the gas refineries in Iran. The participants were selected using the proportional stratified sampling method in 2019. The data collection tools were a demographic information questionnaire, the short form of the International Physical Activity Questionnaire (IPAQ), and a questionnaire developed based on the SCT, whose psychometric features were confirmed in terms of validity and reliability. Data were analyzed using SPSS₂₂ and AMOS₂₀ software. Results: The first version of PAWPQ-SCT had 74 items. After evaluating content and face validity, nine items were removed. The results of the content validity index (0.98), content validity ratio (0.86), and impact score (3.62) were acceptable for the whole instrument. In exploratory factor analysis, after removing seven items-58-item final version of the scale-six factors could explain 73.54% of the total variance. The results of structural equation modeling showed the acceptable fit of the model into the data (RMSEA = 0.052, CFI = 0.917, NFI = 0.878, TLI = 0.905, IFI = 0.917, CMIN/DF = 2.818). Cronbach's alpha coefficient and Intraclass Correlation were 0.90 and 0.86, respectively. Conclusion: This study confirmed that the psychometric features of the 58-item final version of PAWPQSCT constructs were acceptable in a sample of Iranian employees. This questionnaire can be used as a valid and reliable tool to evaluate Iranian employees' PA behaviors and develop effective educational interventions for workers and managers.

Background: The aim of this study was to evaluate the quality of the Second Korean Working Conditions Survey (KWCS), focusing on its validity and reliability. Methods: The external validity was evaluated by the assessment of sampling procedures and the response rate, in order to investigate the representativeness of the sample. The content validity was evaluated by the assessment of the development of the questionnaire, and the consistency of questions for the selected construct. The test-retest method was used to evaluate the reliability by means of a phone call survey of 30% of the respondents, who were randomly selected. The respondents' satisfaction regarding the survey procedures and interview time were analyzed to evaluate the quality of survey data. Results: The external validity was assured by an acceptable sampling procedure, rigid multi-stage stratified cluster random sampling. The content validity was also guaranteed by a reasonable procedure for the development of the questionnaire with a pretest. The internal consistency of the questions for work autonomy was maintained, with 0.738 of Cronbach's alpha. The response rate of 36% was lower than that of the European Working Conditions Survey (EWCS), with a contact rate of 66%, compared to 76% for the EWCS. The matching rates of the five retested questions were more than 98% reliable. Conclusion: The quality of the second KWCS was assured by the high external and content validity and reliability. The rigid sampling procedure and development of the questionnaire contributed to quality assurance. The high level of reliability may be guaranteed by the sophisticated field survey procedures and the development of a technical manual for interviewers. The technical strategies for a high response rate should be developed for future surveys.

Purpose: Oral mucositis (OM) is a serious consequence of chemotherapy that cancer patients must undergo. The objectives of this study were to find out reliability and validity of patients self-reported daily questionnaires on OM, and the impact OM makes on daily functions. Method: To test the reliability of oral mucositis daily questionnaire (OMDQ), internal consistency of the instrument (Cronbach's ${\alpha}$ and correlation between items) and test-retest reliability were analyzed. Criterion validity and discriminative validity were evaluated using WHO, oral assessment guide, and Nicolatou assessment tool. Forty-eight acute leukemic patients under chemotherapy were enrolled in this study. Result: The Cronbach's ${\alpha}$ coefficient indicated sufficient internal consistency. Correlations of Mouth and throat soreness (MTS) and MTSActivity Limitations (MTS-AL) were statistically significant. MTS and MTS-AL scores on consecutive days were highly correlated (days13,14=.84-.96; test-retest reliability). OMDQ scale had high criterion validity and discriminative validity. Patients with more severe WHO OM grades had higher MTS mean scores. Conclusion: Oral mucositis in acute leukemic patients under going chemotherapy can be easily quantified by patient self-administered OMDQ with reliability and validity.
