Measuring health literacy regarding infectious respiratory diseases: a new skills-based instrument.

ABSTRACT:

Background

There is no special instrument to measure skills-based health literacy where it concerns infectious respiratory diseases. This study aimed to explore and evaluate a new skills-based instrument on health literacy regarding respiratory infectious diseases.

Methods

This instrument was designed to measure not only an individual's reading and numeracy ability, but also their oral communication ability and their ability to use the internet to seek information. Sixteen stimuli materials were selected to enable measurement of the skills, which were sourced from the WHO, China CDC, and Chinese Center of Health Education. The information involved the distribution of epidemics, immunization programs, early symptoms, means of disease prevention, individual's preventative behavior, use of medications and thermometers, treatment plans and the location of hospitals. Multi-stage stratified cluster sampling was employed to collect participants. Psychometric properties were used to evaluate the reliability and validity of the instrument.

Results

The overall degree of difficulty and discrimination of the instrument were 0.693 and 0.482 respectively. The instrument demonstrated good internal consistency reliability with a Cronbach's alpha of 0.864. As for validity, six factors were extracted from 30 items, which together explained 47.3% of the instrument's variance. And based on confirmatory factor analysis, the items were grouped into five subscales representing prose, document, quantitative, oral and internet based information seeking skills (?(2)?=?9.200, P>0.05, GFI?=?0.998, TLI?=?0.988, AGFI?=?0.992, RMSEA?=?0.028).

Conclusion

The new instrument has good reliability and validity, and it could be used to assess the health literacy regarding respiratory infectious disease status of different groups.

Project description:BackgroundWith the digitization of health care and the wide availability of Web-based applications, a broad set of skills is essential to properly use such facilities; these skills are called digital health literacy or eHealth literacy. Current instruments to measure digital health literacy focus only on information gathering (Health 1.0 skills) and do not pay attention to interactivity on the Web (Health 2.0). To measure the complete spectrum of Health 1.0 and Health 2.0 skills, including actual competencies, we developed a new instrument. The Digital Health Literacy Instrument (DHLI) measures operational skills, navigation skills, information searching, evaluating reliability, determining relevance, adding self-generated content, and protecting privacy.ObjectiveOur objective was to study the distributional properties, reliability, content validity, and construct validity of the DHLI's self-report scale (21 items) and to explore the feasibility of an additional set of performance-based items (7 items).MethodsWe used a paper-and-pencil survey among a sample of the general Dutch population, stratified by age, sex, and educational level (T1; N=200). The survey consisted of the DHLI, sociodemographics, Internet use, health status, health literacy and the eHealth Literacy Scale (eHEALS). After 2 weeks, we asked participants to complete the DHLI again (T2; n=67). Cronbach alpha and intraclass correlation analysis between T1 and T2 were used to investigate reliability. Principal component analysis was performed to determine content validity. Correlation analyses were used to determine the construct validity.ResultsRespondents (107 female and 93 male) ranged in age from 18 to 84 years (mean 46.4, SD 19.0); 23.0% (46/200) had a lower educational level. Internal consistencies of the total scale (alpha=.87) and the subscales (alpha range .70-.89) were satisfactory, except for protecting privacy (alpha=.57). Distributional properties showed an approximately normal distribution. Test-retest analysis was satisfactory overall (total scale intraclass correlation coefficient=.77; subscale intraclass correlation coefficient range .49-.81). The performance-based items did not together form a single construct (alpha=.47) and should be interpreted individually. Results showed that more complex skills were reflected in a lower number of correct responses. Principal component analysis confirmed the theoretical structure of the self-report scale (76% explained variance). Correlations were as expected, showing significant relations with age (ρ=-.41, P<.001), education (ρ=.14, P=.047), Internet use (ρ=.39, P<.001), health-related Internet use (ρ=.27, P<.001), health status (ρ range .17-.27, P<.001), health literacy (ρ=.31, P<.001), and the eHEALS (ρ=.51, P<.001).ConclusionsThis instrument can be accepted as a new self-report measure to assess digital health literacy, using multiple subscales. Its performance-based items provide an indication of actual skills but should be studied and adapted further. Future research should examine the acceptability of this instrument in other languages and among different populations.

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 (?2/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:BackgroundValid and reliable instruments are required to measure the effect of educational interventions to improve evidence-based practice (EBP) knowledge and skills in occupational therapy. The aims of this paper are to: 1) describe amendments to the Adapted Fresno Test of Competence in EBP (AFT), and 2) report the psychometric properties of the modified instrument when used with South African occupational therapists.MethodsThe clinical utility of the AFT was evaluated for use with South African occupational therapists and modifications made. The modified AFT was used in two studies to assess its reliability and validity. In Study 1 a convenience sample of 26 occupational therapists in private practice or government-funded health facilities in a South African province were recruited to complete the modified AFT on two occasions 1 week apart. Completed questionnaires were scored independently by two raters. Inter-rater, test-retest reliability and internal consistency were determined. Study 2 was a pragmatic randomised controlled trial involving occupational therapists in four Western Cape Department of Health district municipalities (n = 58). Therapists were randomised in matched pairs to one of two educational interventions (interactive or didactic), and completed the modified AFT at baseline and 12 weeks after the intervention. An intention-to-treat analysis was performed. Data were not normally distributed, thus non-parametric statistics were used.ResultsIn Study 1, 21 of 26 participants completed the questionnaire twice. Test-retest (ICC = 0.95, 95 % CI = 0.88-0.98) and inter-rater reliability (Time 1: ICC = 0.995, 95 % CI = 0.99-0.998; Time 2: ICC = 0.99, 95 % CI = 0.97-0.995) were excellent for total scores. Internal consistency based on time 1 scores was satisfactory (α = 0.70). In Study 2, 28 participants received an interactive educational intervention and completed the modified AFT at baseline and 12 weeks later. Median total SAFT scores increased significantly from baseline to 12-weeks (Z = -4.078, p < 0.001) with a moderate effect size (r = 0.55).ConclusionThe modified AFT has demonstrated validity for detecting differences in EBP knowledge between two groups. It also has excellent test-retest and inter-rater reliability. The instrument is recommended for contexts where EBP is an emerging approach and time is at a premium.Trial registrationPan African Controlled Trials Register PACTR201201000346141 .

Project description:BackgroundLifestyle is one of the main determinants of people's health. It is essential to find the most effective prevention strategies to be used to encourage behavioral changes in their patients. Many theories are available that explain change or adherence to specific health behaviors in subjects. In this sense the named Motivational Interviewing has increasingly gained relevance. Few well-validated instruments are available for measuring doctors' communication skills, and more specifically the Motivational Interviewing.Methods/designThe hypothesis of this study is that the Scale for Measuring Motivational Interviewing Skills (EVEM questionnaire) is a valid and reliable instrument for measuring the primary care professionals skills to get behavior change in patients. To test the hypothesis we have designed a prospective, observational, multi-center study to validate a measuring instrument. -ScopeThirty-two primary care centers in Spain. -Sampling and Size: a) face and consensual validity: A group composed of 15 experts in Motivational Interviewing. b) Assessment of the psychometric properties of the scale; 50 physician- patient encounters will be videoed; a total of 162 interviews will be conducted with six standardized patients, and another 200 interviews will be conducted with 50 real patients (n=362). Four physicians will be specially trained to assess 30 interviews randomly selected to test the scale reproducibility. -Measurements for to test the hypothesis: a) Face validity: development of a draft questionnaire based on a theoretical model, by using Delphi-type methodology with experts. b) Scale psychometric properties: intraobservers will evaluate video recorded interviews: content-scalability validity (Exploratory Factor Analysis), internal consistency (Cronbach alpha), intra-/inter-observer reliability (Kappa index, intraclass correlation coefficient, Bland & Altman methodology), generalizability, construct validity and sensitivity to change (Pearson product-moment correlation coefficient).DiscussionThe verification of the hypothesis that EVEM is a valid and reliable tool for assessing motivational interviewing would be a major breakthrough in the current theoretical and practical knowledge, as it could be used to assess if the providers put into practice a patient centered communication style and can be used both for training or researching purposes.

Project description:BACKGROUND:Oral health literacy is an important construct for both clinical and public health outcomes research. The need to quantify and test OHL has led to the development of measurement instruments and has generated a substantial body of recent literature. A commonly used OHL instrument is REALD-30, a word recognition scale that has been adapted for use in several languages. The objective of this study was the development and testing of the Greek language oral health literacy measurement instrument (GROHL). METHODS:Data from 282 adult patients of two private dental clinics in Athens, Greece were collected via in-person interviews. Forty-four words were initially considered and tested for inclusion. Item response theory analysis (IRT) and 2-parameter logistic models assessing difficulty and discriminatory ability were used to identify an optimal scale composition. Internal consistency was examined using Cronbach's alpha and test-retest reliability was measured using intraclass correlation coefficient (ICC) in a subset of 20 participants over a two-week period. Convergent validity was tested against functional health literacy screening (HLS) items, dental knowledge (DK), oral health behaviors (OHBs), oral health-related quality of life (OHRQoL; OHIP-14 index), as well as self-reported oral and general health status. RESULTS:From an initial item pool of 44 items that were carried forward to IRT, 12 were excluded due to no or little variance, 10 were excluded due to low item-test correlation, and 2 due to insignificant contribution to the scale, i.e., difficulty parameter estimate with p?>?0.05. The twenty remaining items composed the final index which showed favorable internal consistency (alpha?=?0.80) and test-retest reliability (ICC?=?0.95). The summary score distribution did not depart from normality (p?=?0.32; mean?=?11.5; median?=?12; range?=?1-20). GROHL scores were positively correlated with favorable oral hygiene behaviors and dental attendance, as well as HLS, DK and education level. CONCLUSION:The GROHL demonstrated good psychometric properties and can be used for outcomes research in clinical and public health settings.
