Development of a health literacy scale for preconception care: a study of the reproductive age population in Japan

Validity and reliability of the translated Marathi version of the 14-item health literacy scale

Introduction

Various tools for measuring health literacy are designed to assess reading comprehension and numeracy in English speakers. There is a need to develop a tool in the vernacular language and estimate health literacy levels in Indian settings. The present study was conducted with the objectives to develop a Marathi version of a 14-item health literacy scale (HLS-14) to test the reliability and validity of its Marathi version and to estimate the health literacy among patients attending the out-patient department at a tertiary care centre.

Methodology

The present study was conducted among 50 adult patients attending the out-patient department of a tertiary hospital from July 2022 to December 2022. The 14-Item Health Literacy Scale available in English was translated into Marathi and back-translated to English, and the final version was developed. Bilingual study subjects were asked to fill the scales on day 0 and on day 7. Cronbach's alpha was calculated for internal validity, and the correlation coefficient was calculated for the reliability of the tool and health literacy was estimated.

Results

When items of the Health Literacy Scale were analysed, all the items barring 2, 6, and 10 gave an r-value of more than 0.70, which shows good reliability of each translated item. The Cronbach's alpha value found for the current translated Marathi questionnaire is 0.66. Internal consistency is good. The mean total health literacy score was 51.16 ± 6.81.

Conclusions

A translated Marathi version of HLS-14 is developed, which is valid and reliable. The health literacy among the study participants is marginal.

Impact of the Social Marketing-Based Intervention on Preconception Healthy Behaviors of Women With Sickle Cell Disease

INTRODUCTION

A suggested method to improve the outcomes of pregnancy with sickle cell disease (SCD) is to engage more women at reproductive age in preconception healthy behavior (PCHB). Social marketing can be a suitable strategy to achieve this goal. We aimed to assess the impact of the social marketing-based intervention on women's engagement in PCHB.

METHODS

A quasi-experimental study was conducted in Bandar Abbas and Minab (the two largest cities of Hormozgan province in Iran with a high prevalence of SCD) from 2021 to 2022. A social marketing-based intervention with the main components (participation in PCHB as a "product," social media and traditional promotional channels as a "promotion," selecting healthcare centers as a "place" for implementing the intervention, and free access to medical experts and speciality as a "price") was designed based on formative research. The sample size was estimated at 140 participants in each intervention and control group. The study's main outcome was the level of engagement in PCHB, which was assessed according to the health belief model (HBM).

RESULTS

We compared the PCHB scores of both groups. Employing healthy behavior was more dominant in the intervention group. Awareness, perceived severity, perceived susceptibility, perceived benefits, and self-efficacy increased in both groups following intervention, while perceived barriers decreased. An analysis of covariance (ANCOVA) was performed to control and moderate the effect of scores in the pretest. As observed between the adjusted averages, awareness, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, and engagement in the PCHB were significantly different between the control and intervention groups after the intervention. A multivariate linear regression analysis showed that awareness, perceived susceptibility, and self-efficacy were strong predictors of PCHB.

CONCLUSIONS

Social marketing-based intervention successfully increased PCHB among women of reproductive age with SCD.

Development and validation of a novel short-form nutrition literacy measurement tool for Chinese college students

Objectives

To develop and validate a short-form nutrition literacy (NL) assessment tool for Chinese college students based on a 43-item NL measurement scale.

Methods

To develop and validate short-form NL scale, 1359 college students were surveyed, the data were analyzed using exploratory factor analysis, linear regression analysis, Item analysis, confirmatory factor analysis, and Pearson correlation.

Results

The 12-item short-form NL scale (NL-SF12) was developed using factor analysis and regression analysis, which accounted for 96.4% of the variance. The correlation coefficient between the NL-SF12 and NL-43 was 0.969, indicating satisfactory criterion-related validity. The NL-SF12 had a Cronbach's α of 0.890, suggesting strong internal consistency reliability, and content validity index was greater than 0.9, indicating that each domain accurately reflects the connotation of nutrition literacy. The model-data fit and convergent validity of the confirmatory factor analysis results were both good.

Conclusion

The NL-SF12 is an effective measurement tool with a good reliability and acceptable validity to assess comprehensively NL for college students, and is applicable to quick, widespread use in population study and practice with low respondent burden.

Measuring health literacy: A systematic review and bibliometric analysis of instruments from 1993 to 2021

BACKGROUND

It has been about 30 years since the first health literacy instrument was developed. This study aimed to review all existing instruments to summarize the current knowledge on the development of existing measurement instruments and their possible translation and validation in other languages different from the original languages.

METHODS

The review was conducted using PubMed, Web of Science, Scopus, and Google Scholar on all published papers on health literacy instrument development and psychometric properties in English biomedical journals from 1993 to the end of 2021.

RESULTS

The findings were summarized and synthesized on several headings, including general instruments, condition specific health literacy instruments (disease & content), population- specific instruments, and electronic health. Overall, 4848 citations were retrieved. After removing duplicates (n = 2336) and non-related papers (n = 2175), 361 studies (162 papers introducing an instrument and 199 papers reporting translation and psychometric properties of an original instrument) were selected for the final review. The original instruments included 39 general health literacy instruments, 90 condition specific (disease or content) health literacy instruments, 22 population- specific instruments, and 11 electronic health literacy instruments. Almost all papers reported reliability and validity, and the findings indicated that most existing health literacy instruments benefit from some relatively good psychometric properties.

CONCLUSION

This review highlighted that there were more than enough instruments for measuring health literacy. In addition, we found that a number of instruments did not report psychometric properties sufficiently. However, evidence suggest that well developed instruments and those reported adequate measures of validation could be helpful if appropriately selected based on objectives of a given study. Perhaps an authorized institution such as World Health Organization should take responsibility and provide a clear guideline for measuring health literacy as appropriate.

A Questionnaire-Based Study to Evaluate Health-Related Behaviors in 602 Women of Reproductive Age in Poland

BACKGROUND Women's health and undertaking health behaviors during the reproductive period by women, especially during pregnancy, are an important indicator that is reflected both in their own health and in health of their children. This study aimed to use a questionnaire to evaluate the health-related behaviors in women of reproductive age in Poland. MATERIAL AND METHODS The studies were conducted among 602 women of reproductive age by diagnostic poll method with the use of questionnaire technique. The applied tool was an original on-line questionnaire. A link to the questionnaire was sent to women aged 18-49 years using the snowball sampling technique and was posted on thematic pro-health website forums. RESULTS The majority of women participating in the study exhibited health behaviors on the average level (65.3%; M=7.6). Pro-health behaviors were exhibited mainly by women with higher education (M=7.7; SD=2.6), married women (M=8.0; SD=2.6), and women who were pregnant at the time (M=8.8; SD=2.6). However, single women participating in the study consumed alcohol more often (80.6%). The observed relationships were statistically significant (P<0.05). CONCLUSIONS This survey showed that younger women with no children were significantly less likely to be aware of positive health-associated behaviors and lifestyle when compared with older women with children. This small study supports the importance of health education in young women before they have children.
