Validating the European Health Literacy Survey Questionnaire in people with type 2 diabetes: Latent trait analyses applying multidimensional Rasch modelling and confirmatory factor analysis

Objective: to investigate the psychometric properties of the Brazilian Portuguese version of the health literacy questionnaire European Health Literacy Survey Questionnaire short-short form (HLS-EU-Q6) in Brazilian adults. Method: the instrument was translated and pre-tested in a sample of 50 individuals. Subsequently, it was applied to a sample of 783 adult individuals. The data went through an appropriate process of testing the properties, with the combination of techniques of Exploratory Factor Analysis, Confirmatory Factor Analysis and Item Response Theory. For the assessment of reliability, the Cronbach's alpha and McDonald's Omega indicators were used. Cross-validation with full data analysis was applied. Results: the majority of the participants was female (68.1%), with a mean age of 38.6 (sd=14.5) years old and 33.5% studied up to elementary school. The results indicated a unidimensional model with an explained variance of 71.23%, adequate factor load levels, commonality and item discrimination, as well as stability and replicability of the instrument to other populations. Conclusion: the Brazilian version of HLS-EU-Q6 indicated that the instrument is suitable for indiscriminate application in the population to which it is intended to assess health literacy levels.

Item Scale

Abstract Background: The European Health Literacy Survey Questionnaire (HLS-EU-Q47) is becoming a widely used tool to measure health literacy (HL), including in Malaysia. There are efforts to reduce the 47-item scale to parsimonious short item scales that still reflect the assumptions and requirements of the conceptual model. This study used confirmatory factor analysis to reduce the 47-item scale to a short scale that can offer a feasible HL screening tool with sufficient psychometric properties. Methods: A cross-sectional survey was conducted on the Malaysian population based on ethnic distribution to ensure that the short version instrument reflects the country’s varied ethnicities. The survey was administered by well-trained interviewers working for the Ministry of Health Malaysia. A total of 866 responses were obtained. Data was analysed using multi-factorial confirmatory factor analysis (CFA) with categorical variables. Results: The analysis resulted in a satisfactory 18-item model. There were high correlations among the 18 items. The internal consistency reliability was robust, with no floor/ceiling effects. These results represented equivalence and consistency among the responses to items, suggesting that these items were homogenous in measuring Malaysian health literacy. The strong convergent and discriminant validity of the model makes the proposed 18 items a suitable short version of the health literacy instrument for Malaysia. Conclusions: The researchers propose the 18-item instrument to be named HLS-M-Q18. This short version instrument may be used in measuring health literacy in Malaysia as it achieved robust reliability, structural validity and construct validity that fulfilled goodness-of-fit criteria.

The European Health Literacy Survey Questionnaire was translated into Turkish following a validity and reliability study, but there is no comprehensive short form available. We aimed to suggest a short form of the 47-item Turkish version of European Health Literacy Survey Questionnaire in this study. Data were obtained from a cross-sectional study that included a total of 686 students, 345 male and 341 female, conducted in nine different faculties of a university using the Turkish version of European Health Literacy Survey Questionnaire. The development process of the short form was conducted using principal component analysis with exploratory factor analysis, and correlation and regression analyses. The validation process was done using confirmatory factor analysis and regression analysis. Based on the results, a 12-item short form was developed, retaining the conceptual framework of the European Health Literacy Survey Questionnaire. The short form was shown to have adequate psychometric properties with high reliability, good validity, a high and moderate level of correlation, and a good model fit with the independent dataset in this cross-sectional study. The short form developed in this study was demonstrated to be a valid and reliable tool to measure health literacy easily and rapidly in Turkey.

Purpose: A study was conducted to investigate the Turkish Validity and Reliability of the Insulin Initiation Attitudes Scale of individuals with Type 2 diabetes. Materials and methods: This methodologically planned study was conducted with 128 Type 2 diabetes mellitus patients who met the sampling criteria. Data collected using a personal information form to identify individuals diagnosed with diabetes and CH-ASIQ, which assessed their attitudes towards diabetes, and the form Insulin Therapy Attitude Scale parallel as a parallel form. For the statistical analysis of the data, Construct Validity, Exploratory Factor Analysis, and Kaiser-Meyer-Olkin test, Confirmatory Factor Analysis, Pearson, Gutmann, Split Half, Spearman, Cronbach Alpha coefficient methods were used. Results: It was statistically significant; it is seen that 14.1% of the participants were in the 41-50 age range, 37.5% were in the 51-60 age range, and 48.8% were 61 and over. According to Kaiser-Meyer-Olkin test, the result was found to be 0.626. According to the results of factor analysis, 4 factors have emerged which have Eigenvalues above 1 and explain 69.48% of the total variance. According to Confirmatory Factor Analysis, Structural Equation Modeling Results of the scale were found to be p=0.000. According to Cronbach Alpha result 0.756. Conclusion: There was a relationship between attitudes to having information about the treatment of diabetics and attitude, and there was the relationship between them. Effects of fear, pain on these findings were observed. The importance of education for a positive attitude was determined. The importance of patients' attitudes towards insulin therapy should be emphasized for adaptation to the disease.

Purpose: The purpose of this study is to translate the Perceived Therapeutic Efficacy Scale (PTES) into Korean and investigate its validity and reliability. Methods: The authors conducted a cross-sectional survey using baseline data from a randomized controlled study to psychometrically validate the PTES-Korean (PTES-K) among 108 adults with type 2 diabetes from an outpatient clinic at a university-affiliated hospital in Korea. The original PTES was forward-translated and back-translated to ensure translation equivalence of the PTES-K. Structured questionnaires were used for psychometric evaluation; exploratory and confirmatory factor analysis assessed validity, and Cronbach’s alpha coefficient and intraclass correlation coefficient (ICC) were used for reliability. Results: The interitem correlation analyses revealed that 5 items were redundant; thus, the scale was reduced to 5 items. A 1-factor model explained 76.85% of the variance; confirmatory factor analysis showed that this model adequately fit the data. The ICC for test-retest reliability was .78; Cronbach’s alpha was .92. The PTES-K showed significant associations with the scores of diabetes self-care activities for physical activity, quality of life, and depressive symptoms. Participants with good glycemic control and regular physical activity tended to have a higher score on the PTES-K than their counterparts, demonstrating known-groups validity. Conclusions: The cross-cultural applicability, reliability, and validity of the PTES-K were confirmed. The PTES-K may be used in clinical settings to examine the potential role of perceived therapeutic efficacy for physical activity in enhanced glycemic control among patients with diabetes.
