Development and Validation of the Breastfeeding Literacy Assessment Instrument (BLAI) for Obstetric Women.

ABSTRACT:

Background

Despite international efforts to protect and promote exclusive breastfeeding (EBF) for infants up to six months of age, global rates of EBF continue to fall short of the targets proposed by the WHO for 2025. Previous studies have shown a relationship between the level of health literacy and the duration of EBF, although this relationship was not determinant, probably due to the use of a generic health literacy questionnaire. Therefore, this study aims to design and validate the first specific breastfeeding literacy instrument.

Methods

A Breastfeeding Literacy instrument was developed. Content validation was carried out by a group of 10 experts in health literacy, breastfeeding or instrument validation, obtaining a Content Validity index in Scale (S-CVI/Ave) of 0.912. A multicentre cross-sectional study was carried out in three Spanish hospitals to determine the psychometric properties (construct validity and internal consistency). The questionnaire was administered to 204 women during the clinical puerperium.

Results

The Kaiser-Meier-Oklin Test (KMO = 0.924) and Bartlett's Test of Sphericity (X² = 3119.861; p ≤ 0.001) confirmed the feasibility of the Exploratory Factor Analysis, which explained 60.54% of the variance with four factors.

Conclusions

The Breastfeeding Literacy Assessment Instrument (BLAI) consisting of 26 items was validated.

Project description:BackgroundThe need for digital literacy in aging populations is increasing in the digitalizing society. Digital literacy involves the identification, evaluation, and communication of information through various digital devices or relevant programs.ObjectiveThe aims of this study were to develop an Everyday Digital Literacy Questionnaire (EDLQ), a digital literacy assessment scale, and subsequently evaluate its psychometric properties using a population of community-dwelling older adults in South Korea.MethodsThe EDLQ was developed using an instrument development design. A nationwide survey was conducted, and the study included 1016 community-dwelling older adults (age ≥60 years). To evaluate the psychometric properties, the participants were randomly divided into 2 groups (n=508 each), and the internal consistency (Cronbach α and McDonald ω), structural validity (exploratory factor analysis and confirmatory factor analysis), hypothesis-testing construct validity using the eHealth Literacy Scale (eHEALS), and measurement invariance were analyzed.ResultsAmong the initial 30 items of the EDLQ, 22 items with a 3-factor solution had a total explained variance of 77%. The domains included "information and communication" (9 items), "content creation and management" (4 items), and "safety and security" (9 items). Confirmatory factor analysis was conducted with this 3-factor solution (χ2206=345.1; normed χ2206=1.7; comparative fit index=0.997; Tucker-Lewis index=0.997; root-mean-square error of approximation=0.036; standardized root-mean-square residual=0.050; composite reliability=0.903-0.959; average variance extracted=0.699-0.724; R2=0.616-0.773). Hypothesis-testing construct validity with the eHEALS revealed a strong correlation (r=0.75). Cronbach α and McDonald ω coefficients were .98 and 0.98, respectively. The fit indices for measurement invariance, including the configural, metric, and scalar invariance models, demonstrated a satisfactory fit to the data. Our findings suggest that the psychometric properties of the 22-item EDLQ are valid and reliable for assessing digital literacy among older Korean adults.ConclusionsIn this study, we developed a digital literacy measure with strong psychometric properties that made it suitable for assessing the digital literacy of community-dwelling older adults in Korea. To broaden its applicability, however, further assessment of its feasibility for use with different languages and cultures is necessary. Moreover, more empirical research on digital literacy and related factors in older adults can facilitate the development of personalized digital health care services and educational interventions in the digital society.

Project description:BACKGROUND:Health literacy is the ability to access to, understand, evaluate and use of essential health information to make basic health decisions. This study aimed to develop and psychometrically evaluate an instrument for measuring health literacy among adults (the Health Literacy Instrument for Adults - HELIA). METHODS:In addition to a literature review, a panel of specialists from different disciplines was formed to generate an item pool. Then, a framework was defined to develop the initial questionnaire based on a definition of health literacy and the most important global public health issues. The initial questionnaire contained 66 items. Next, 15 experts in public health were approached to assess content validity. Consequently, 19 items were removed and a provisional version of the questionnaire with 47 items was provided. Finally, a random sample of adults completed the questionnaire and psychometric properties of the instrument were assessed. RESULTS:Overall, 323 adults aged 18 to 65 years old completed the questionnaire. When the exploratory factor analysis was performed, 33 items were loaded, which indicated a 5-factor solution for the questionnaire that jointly explained 52.9% of the variance observed. The factors were as follows: access to information (6 items), reading (4 items), understanding (7 items), appraisal (4 items), and decision making/behavioral intention (12 items). Confirmatory factory analysis also indicated a good fit to the data for the five-latent structure (χ2/df = 1.60, SRMR = 0.049; RMSEA = 0.043; CFI = 0.98; NFI = 0.95; NNFI = 0.98 and GFI = 0.87). Additional analysis for internal consistency showed satisfactory results with Cronbach's alpha coefficients ranging from 0.72 to 0.89. Intraclass correlation coefficient (test-retest analysis) also showed acceptable stability for the questionnaire (ICC = 0.84). The mean score for health literacy as measured by the HELIA was 76.3 (SD = 15.1) out of 100 for the study sample. CONCLUSION:The findings suggest that the Health Literacy Instrument for Adults (HELIA) is a valid and reliable instrument for measuring health literacy. It is a short and easy-to-use instrument that could be applied in different settings.

Project description:AimTo develop a consensus-based instrument [MELIA] to assess the medication literacy of older home care patients to ultimately optimize medication safety.DesignThis study was part of the project 'Study of Medication Safety in Home Care' (doMESTIC), which took place from 2016 to 2020 in Switzerland. The development process for the medication literacy assessment instrument encompassed six steps.MethodFirst, a scoping literature search was conducted in the Pubmed, CINAHL, EMBASE and Cochrane Library databases as 2) a basis for the development of assessment items. This was followed by 3) a cognitive interview with home care patients and 4) the first round of a Delphi process. Then, 5) a focus group interview with home care experts was conducted before 6) the second Delphi round. The project took place between August 2020 and June 2021. With these different steps, perspectives of both patients and various home care and medication safety experts were included in the development of the assessment instrument.ResultsA detailed instrument consisting of 20 items as well as a 7-item short version were developed. The short version is intended for efficient preliminary screening to identify patients at high risk for medication management-related problems.ConclusionMedication literacy in patients 65 years and older receiving professional home care is a key issue in preventing medication errors. A targeted assessment, starting with an efficient short version of MELIA, allows for prioritization of patients for interventions to optimize medication safety while ensuring their independence as much as possible.ImpactSystematic assessment of patients' medication literacy helps to provide them with targeted and individual support in their medication management to avoid medication errors and increase patient safety. The development of MELIA is a first step in providing an assessment instrument specifically for the home care setting.Patient or public contributionPatient participation was an integral part of the instrument development. The initial 23 items were optimized based on cognitive interviews with four home care patients. The next steps of the instrument development were based on feedback of health care professionals-encompassing advance practice nurses, regular nurses, pharmacists and general practitioners-during a two-step Delphi process as well as a focus group discussion.

Project description:BackgroundResearch concerning health literacy among migrant workers in South Korea has been limited, especially given the lack of validated instruments and the lack of focus on the cultural diversity of migrant workers.ObjectiveThis study aimed to develop and validate a health literacy scale for unskilled migrant workers (HLS-MW) in South Korea.MethodsWe first generated a pool of potential items based on a literature review and in-depth interviews with 23 migrant workers. Subsequently, we reviewed empirical referents from the first step to select relevant medical terminologies and passages, ultimately choosing 709 words. The study team initially generated 35 items with 709 health-related terms through empirical referent reviews. After content validity testing by an expert panel, 28 items comprising 89 terms on the 2 subscales of prose and documents were selected for psychometric testing. Overall, 402 unskilled migrant workers in South Korea completed a web-based survey between August and September 2021, with 334 responses included in the final analysis. We used multiple analytic approaches, including exploratory factor analysis, Rasch analysis (item response theory), and descriptive analysis, to examine the new scale's validity and reliability.ResultsThe final sample primarily included young male workers from South Asian countries. The HLS-MW yielded 2 factors: prose and documents. The item difficulty scores ranged from -1.36 to 2.56. The scale was reduced to 13 items (10 prose and 3 document items), with the final version exhibiting good internal reliability (Kuder-Richardson index=0.88; intraclass correlation coefficient=0.94, 95% CI 0.93-0.95) and test-retest reliability (r=0.74, 95% CI 0.57-0.92). HLS-MW scores differed significantly by Korean language proficiency (F2,331=3.54, P=.004).ConclusionsThe HLS-MW is a reliable and valid measure to assess health literacy among migrant workers in South Korea. Further studies are needed to test the psychometric properties of the HLS-MW in diverse migrant groups in South Korea while also establishing cutoffs to help identify those in need of health literacy support.
