Psychometric characteristics of the Chinese version of the Pregnancy Exercise Attitudes Scale (C-PEAS).

Reasonable instruction and promotion of appropriate exercise are crucial to improving the exercise status of pregnant women and safeguarding the health of both mother and fetus. However, there is a lack of validated Pregnancy Exercise Attitude Scales with a complete evaluation system in China. This study aims to assess the validity and reliability of the Pregnancy Exercise Attitude Scale (C-PEAS) in Chinese to give medical professionals a reference for carrying out pregnancy care services and promoting the health of the mother and fetus. In this study, the scale was translated, back-translated, and cross-culturally adapted using the Brislin translation model to form the C-PEAS. 528 pregnant women were conveniently selected for the questionnaire survey to evaluate the scale's reliability. The scale's content validity was assessed by the content validity index, while its structural validity was investigated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Cronbach's alpha coefficient, McDonald's omega coefficient, split-half reliability, and retest reliability were used to evaluate the scale's internal consistency. The C-PEAS contains two dimensions with 37 entries. The EFA supports a two-factor structure with a cumulative variance contribution of 62.927%. The CFA model was well fitted (χ2/df = 1.597, RMSEA = 0.048, IFI = 0.955, TLI = 0.952, and CFI = 0.955). The C- PEAS' Cronbach's alpha coefficient was 0.973, and the range of Cronbach's alpha values for the dimensions was 0.976, 0.944. McDonald's omega coefficient was 0.971, the half-point reliability of the scale was 0.856, and the retest reliability was 0.966. The Chinese version of C-PEAS has good psychometric properties. It can be used as an effective measurement tool to evaluate the attitude of pregnant women to exercise during pregnancy.

Reliability and validity of the Chinese version of the coronary artery disease empowerment scale (CADES) in patients with coronary artery disease after percutaneous coronary intervention.

Empowerment is a comprehensive concept involving intrapersonal, interactional, and behavioral aspects. However, there is a lack of a specific empowerment scale for Coronary artery disease (CAD) related to knowledge and skills in China. The reliability and validity of the Coronary Artery Disease Empowerment Scale (CADES) need to be tested. This study aimed to assess the reliability and validity of the Chinese version of CADES among patients with CAD in China. The study adopted a cross-sectional design. After obtaining the copyright by contacting the author, the original English CADES was developed into Chinese by forward translation, back-translation, cross-cultural adaptation, and a pretest (30 patients). The Chinese version of CADES was administered to 391 CAD patients between September 2022 and June 2023, with the reliability and validity of the version evaluated. Exploratory factor analysis and confirmatory factor analysis were performed to examine the underlying factor structure of the translated questionnaire. The Cronbach's α coefficient, Guttman's split-half coefficient, and McDonald's omega coefficient were calculated to verify the scale's reliability. For the Chinese version of CADES, the scale-content validity index was 0.972, with the item-content validity index ranging from 0.86 to 1.00. The questionnaire comprised 25 items, and exploratory factor analysis extracted four factors with loadings > 0.40, explaining 62.382% of the total variance. An acceptable model fit was achieved (χ2/df = 1.764, RMSEA = 0.060, TLI = 0.901, CFI = 0.912, IFI = 0.913). The Cronbach's α coefficient of the total questionnaire was 0.928, with coefficients for the four factors ranging from 0.683 to 0.913. The split-half reliability coefficient was 0.777, and the McDonald's omega reliability coefficient was 0.926. The Chinese version of CADES is reliable and valid among CAD patients in China. This instrument can serve as a valuable reference for guiding the implementation of targeted intervention strategies tailored to the empowerment status of CAD patients in clinical practice.

Psychometric properties of the chinese version of the value-based stigma inventory (VASI): a translation and validation study.

This study aimed to develop a culturally adapted Chinese version of the Value-based Stigma Inventory (VASI) and to evaluate its psychometric properties, including reliability and validity, among the general Chinese population. This study is a cross-sectional study. Convenience sampling was used to recruit 708 general citizens from Shenyang City, Liaoning Province, China. The VASI's internal consistency, split-half reliability, and test-retest reliability were tested to assess the translated scale's reliability. Several validity tests were performed, including expert consultation, exploratory factor analysis, and confirmatory factor analysis. Data were analyzed using SPSS 25.0 (IBM Corp., Armonk, NY, United States) and AMOS 23.0 (IBM Corp., Armonk, NY, United States). The Chinese version of the VASI showed good reliability, with a Cronbach's α value of 0.808, and the dimensions ranged from 0.812 to 0.850. Test-retest reliability showed good temporal stability with a value of 0.855, and the split-half reliability value was 0.845, indicating a high degree of consistency. The scale also demonstrated good content validity with a content validity index of 0.952. After conducting exploratory factor analysis, a five-factor structure was identified, including factors of self-realization, personal enrichment, reputation, meritocratic values, and security. In the confirmatory factor analysis, all recommended fit indicators were found to be within the acceptable range, including χ2/DF = 1.338, GFI = 0.960, AGFI = 0.940, RMSEA = 0.031, TLI = 0.985, CFI = 0.989, IFI = 0.989, PGFI = 0.640, and PNFI = 0.729. The Chinese version of the VASI is valid and reliable among the Chinese general public. The five-factor structured scale effectively assessed public stigma against mental illness, including the value orientations associated with personal stigma. Given the harsh and widespread public stigma against mental illness, the findings from the questionnaire may inform the development of future public health education programs. Public health education is needed to reduce the stigma of mental illness, increase public awareness of mental health issues, and mitigate the continued stigmatization of mental illness.

Psychometric evaluation of the body understanding measure pregnancy scale Chinese version for pregnant Chinese women.

At present, there is limited research on pregnancy body image and no valid tool to measure body image in pregnant Chinese women. The purpose of this study was to translate the Body Understanding Measure Pregnancy Scale into Chinese to determine its reliability and validity in measuring body image in pregnant women. The translation of the Body Understanding Measure Pregnancy Scale (BUMPs) was carried out with a standardized procedure. This study was conducted from July to December 2020 in the outpatient department of three tertiary hospitals in China. There were 1069 pregnant women completed the questionnaire and 1057 of those women were included in the analysis. Internal consistency, test-retest reliability, content validity, and construct validity of the translation version were examined. The final Chinese version of the BUMPs (BUMPs-C) had four dimensions with 16 items. Exploratory factor analysis obtained a three-factor solution, which explained 50.26% of the total variances. Confirmatory factor analysis showed that the model fit of the four-factor model was better than the three-factor model, and the four-factor model also reached a satisfactory model fit after modifying: Minimum Discrepancy was 2.82; Comparative Fit Index was 0.939, and Tucker-Lewis Index was 0.92; Root Mean Square Error of Approximation was 0.059. The content validity index of the scale was 1.0; the Cronbach's alpha (α) coefficient was 0.82 for the total scale, the McDonald's omega (ω) coefficient was 0.829; the test-retest reliability was 0.796. The BUMPs-C showed good reliability and validity among pregnant Chinese women, which can be used as a simple and valid measurement tool to assess the feelings of pregnant Chinese women on body changes during pregnancy.
