Chinese health literacy scale for tuberculosis patients: a study on development and psychometric testing

Health literacy and tuberculosis control: systematic review and meta-analysis

Objective

To identify literature on health literacy levels and examine its association with tuberculosis treatment adherence and treatment outcomes.

Methods

Two authors independently searched Pubmed®, Embase, CINAHL, PsycINFO, Scopus, LILACS, Global Health Medicus and ScienceDirect for articles reporting on health literacy levels and tuberculosis that were published between January 2000 and September 2023. We defined limited health literacy as a person's inability to understand, process, and make decisions from information obtained concerning their own health. Methodological quality and the risk of bias was assessed using the JBI critical appraisal tools. We used a random effects model to assess the pooled proportion of limited health literacy, the association between health literacy and treatment adherence, and the relationship between health literacy and tuberculosis-related knowledge.

Findings

Among 5813 records reviewed, 22 studies met the inclusion criteria. The meta-analysis revealed that 51.2% (95% confidence interval, CI: 48.0-54.3) of tuberculosis patients exhibit limited health literacy. Based on four studies, patients with lower health literacy levels were less likely to adhere to tuberculosis treatment regimens (pooled odds ratio: 1.95; 95% CI: 1.37-2.78). Three studies showed a significant relationship between low health literacy and inadequate knowledge about tuberculosis (pooled correlation coefficient: 0.79; 95% CI: 0.32-0.94).

Conclusion

Health literacy is associated with tuberculosis treatment adherence and care quality. Lower health literacy might hamper patients' ability to follow treatment protocols. Improving health literacy is crucial for enhancing treatment outcomes and is a key strategy in the fight against tuberculosis.

Development and validation of knowledge assessment scales on sarcopenia and fall for Chinese community-dwelling older adults

AIM

This study aimed to develop and validate sarcopenia and fall knowledge assessment scales for community-dwelling older adults.

METHODS

A five-phase, systematic and standardized process was used. Phase 1: item pools were constructed based on the Symptom Interpretation Model. Phase 2: the Delphi expert consultation was carried out for items selection and revision. Phase 3: a pilot survey was carried out to further select and revise the items. Phase 4: older adults were surveyed to finalize the items. Phase 5: older adults were surveyed to test the psychometric properties of the two developed scales, including construct validity, reliability and acceptability.

RESULTS

Both scales comprise three dimensions (symptom, risk factor and management strategy), with 10 items for the sarcopenia knowledge assessment scale and 14 items for the fall knowledge assessment scale. They had acceptable construct validity, with all indicators meeting their specific criteria. Their reliability was acceptable, with the Cronbach's α coefficients being 0.82 for both scales, the value of spilt-half reliability being 0.86 for the sarcopenia knowledge assessment scale and 0.85 for the fall knowledge assessment scale. Their acceptability was good, with both scales having a completion rate of 94.35% and an average completion time of 5 min.

DISCUSSION

Two Chinese knowledge assessment scales with acceptable validity, reliability and acceptability have been developed, which will facilitate the assessment of the knowledge on sarcopenia and fall among community-dwelling older adults, especially for large-scale surveys.

The mothers' breastfeeding behaviour within six weeks postpartum: new scale development and psychometric validation study

BACKGROUND

The evaluation of mothers' breastfeeding behaviour within 6 weeks postpartum could help health workers comprehensively identify maternal breastfeeding shortcomings, clarify nursing problems, and provide targeted interventions. However, no prior study was found, therefore this study aimed to develop and validate the reliability and validity of the mothers' breastfeeding behaviour scale within 6 weeks postpartum.

METHODS

A main two-step approach was used: (1) a qualitative pilot study using the purposive sampling method was adopted to test the fitness, simplicity, and clarity of items with 30 mothers; (2) a cross-sectional survey using the convenient sampling method was conducted for item analysis and psychometric validation with 600 mothers.

RESULTS

The final version of the scale consisted of 36 items with seven dimensions, explaining 68.852% of the total variance. The Cronbach's α, split-half, and retest coefficients were 0.958, 0.843, and 0.753, respectively. The validity of the scale: (1) Content validity: content validity index (CVI) range of items was between 0.882 and 1.000. The scale-level-CVI was 0.990. (2) Structure validity: The fitting indices were as follows: χ²/ⅆf =2.239, RMR = 0.049, RMSEA = 0.069, TLI = 0.893, CFI = 0.903, IFI = 0.904, PGFI = 0.674, and PNFI = 0.763. (3) Convergent validity: The composite reliability and average variance extracted (AVE) of the seven dimensions were between 0.876 and 0.920 and between 0.594 and 0.696. (4) Distinguish validity: The correlation coefficients were less than the square root of the AVE, except for self-decision behaviour, self-coping behaviour, and self-control behaviour. However, the fit index of the original three-factor model was better than that of the other new models, with significant differences (P < 0.001). (5) Calibration validity: The area under the curve was 0.860 or 0.898 when the scale was used to predict exclusive or any breastfeeding at 42 days. The correlation coefficients of the maternal breasting feeding evaluation scale, breastfeeding self-efficacy short-form scale, and the scale were 0.569 and 0.674, respectively.

CONCLUSION

The newly developed mothers' breastfeeding behaviour scale within 6 weeks postpartum consists of 36 items belonging to seven dimensions with good reliability and validity and is a reliable and valid instrument to be used in future maternal breastfeeding behaviour assessments and interventions.

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.

Breast Cancer Stigma Scale: A Reliable and Valid Stigma Measure for Patients With Breast Cancer

Purpose

This study aims to develop and validate a stigma scale for Chinese patients with breast cancer.

Methods

Patients admitted to the Affiliated Cancer Hospital of Xiangya School of Medicine, Central South University, for breast cancer treatment participated in this study. Development of the Breast Cancer Stigma Scale involved the following procedures: literature review, interview, and applying a theoretical model to generate items; the Breast Cancer Stigma Scale’s content validity was assessed by a Delphi study (n = 15) and feedback from patients with breast cancer (n = 10); exploratory factor analysis (n = 200) was used to assess the construct validity; convergent validity was assessed with the Social Impact Scale (n = 50); internal consistency Cronbach’s α (n = 200), split-half reliability (n = 200), and test–retest reliability (N = 50) were used to identify the reliability of the scale.

Results

The final version of the Breast Cancer Stigma Scale consisted of 15 items and showed positive correlations with the Social Impact Scale (ρ = 0.641, P < 0.001). Exploratory factor analysis (EFA) revealed four components of the Breast Cancer Stigma Scale: self-image impairment, social isolation, discrimination, and internalized stigma, which were strongly related to our perceived breast cancer stigma model and accounted for 69.443% of the total variance. Cronbach’s α for the total scale was 0.86, and each subscale was 0.75–0.882. The test–retest reliability with intra-class correlation coefficients of the total scale was 0.947 (P < 0.001), and split-half reliability with intra-class correlation coefficients of the total scale was 0.911 (P < 0.001). The content validity index (CVI) was 0.73–1.0.

Conclusion

The newly developed Breast Cancer Stigma Scale offers a valid and reliable instrument for assessing the perceived stigma of patients with breast cancer in clinical and research settings. It may be helpful for stigma prevention in China.

A new comprehensive oral health literacy scale: development and psychometric evaluation

BACKGROUND

It has been widely accepted that oral health status is related to oral health literacy. The need to measure oral health literacy has led to the development of measurement instruments. This study aimed to develop a comprehensive instrument for adults and to examine its reliability and validity in China.

METHODS

A three-step design process was used. First, a literature review and expert panel discussion were used to draw up a 37-item pool covering oral health knowledge, belief, practice, skill, and functional oral health literacy. The Delphi method was used to delete and modify questions in the item pool. The draft instrument was evaluated by nine experts and the consensus among them was calculated using the content validity index. The scale was then used to conduct a psychometric study among 370 participants from community health centers in Beijing. Construct validity, discriminant validity and concurrent validity were examined. The Cronbach's alpha coefficient, and test-retest methods were used to assess reliability.

RESULTS

The final scale included 30 items across four dimensions. The item-level content validity index was 0.90. Exploratory factor analysis extracted four fixed factors, and the result of the Kaiser-Meyer-Olkin and Bartlett's tests was 0.752, with the model explaining 35.21% of the total variance. The four dimensions were associated with oral health knowledge, perceptions of oral health issues, oral health practice and skills, and functional oral health literacy. The mean score of the lowest 27% was significantly lower than the highest 27% (P < 0.01), suggesting adequate discriminant validity. The associations between comprehensive oral health literacy scores and educational level, income and self-reported literacy level were significant (P < 0.001), showing adequate overall concurrent validity. Internal consistency and test-retest reliability were acceptable, with a Cronbach's alpha of 0.72 and a total test-retest reliability coefficient of 0.979.

CONCLUSIONS

Initial testing of the comprehensive oral health literacy instrument suggested that it is a valid and reliable instrument to evaluate individuals' oral health literacy, with four dimensions for evaluating knowledge, belief, skills, and functional oral health literacy.

Application of the information-motivation-behavioral-skills model to validate a cognitive and behavioral intervention scale for tuberculosis patients in Jos, Nigeria

Psychometric scales can be used to assess the cognition of and behavior toward tuberculosis (TB) disease and anti-TB medicines in TB patients by applying the Information-Motivation-Behavioral-Skills model. This study validated a psychometric scale from the responses of 115 TB patients using principal component (PCA) and reliability analyses. The Cronbach's-alpha was 0.864. The PCA identified 21 factors, with eigenvalues greater than one. Six factors, with factor loading >0.5 had more than two items loaded to a factor. Twenty-five items validated from six factors suggest that the scale can be used for cognitive and behavioral assessment and interventions in tuberculosis patients.

Development and Validation of Peer Relationship Scale for Chinese Community-Dwelling Elderly

INTRODUCTION

This study aimed to develop and psychometrically test the peer relationship scales (PRSs) for the Chinese community-dwelling elderly.

METHODS

Based on the Adams-Blieszner-Ueno integrative conceptual framework, we first drafted item-pool from the literature review, in-depth interviews, and group discussion. After a cross-sectional study in Chongqing, PR, China, we recruited a random sample of 404 community-dwelling individuals aged ≥ 65 years. Subsequently, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to examine the factor structure of the scales. Cronbach's alpha coefficient and split-half reliability were used to assess internal consistency. Moreover, test-retest reliability, concurrent validity, and construct validity were all calculated.

RESULTS

The results supported a two-factor (ie, quantity of intimate peer relationship, the quantity of non-intimate peer relationship) model for PRS-Quantity and a 12-item three-factor (ie, cognitive process, affective process, behavioral process) model for PRS-Quality. The Cronbach's alpha was 0.870 for PRS-Quantity and 0.851 for PRS-Quality. Both scales showed good test-retest reliability (r = 0.890 for PRS-Quantity, r = 0.889 for PRS-Quality), concurrent validity (r = 0.832 for PRS-Quantity, -0.800 for PRS-Quality), and acceptable construct validity.

DISCUSSION

Overall, our findings suggested that the PRSs are reliable and valid measurements to evaluate the quantity and quality of peer relationships among Chinese community-dwelling elderly. The scales may serve as attempted tools for researchers and practitioners to access the social health of the elderly and evaluate the effectiveness of related services.

Ideal instruments used to measure health literacy related to medication use: A systematic review

BACKGROUND

Prior studies showed the association between inadequate health literacy (HL) and poor medication-related skills, while none of the published studies have reviewed and compared the existing instruments used to measure medication-related HL. This systematic review comprehensively summarizes the existing instruments that assess medication-related HL.

OBJECTIVES

To identify appropriate HL instruments related to medication use as screening tools for enhancing patients' ability to use medications correctly.

METHODS

This review retrieved medication-related HL instruments that were published between 2000 and 2019 from three databases (i.e., PubMed, Scopus, EMBASE) and by hand-searching. The PRISMA procedure was followed as well as the SURGE guideline to assess the quality of studies. Psychometric properties, HL dimensions, and types of medication information gleaned from the items in three types of HL instruments (i.e., general, disease-specific, medication-specific) were compared to identify appropriate medication-related HL instruments.

RESULT

Forty-eight instruments were identified from 44 studies, whereas 70.8% instruments were either disease- or medication-specific HL instruments. Most instruments with different sample sizes showed certain an extent of reliability and validity. The distributions of HL dimensions and types of medication information among the relevant items were varied across different types of instruments. The five instruments (named as the 16SQ, AKQ-CQ, DHLKI, AKT, and ChMLM) were identified as the most appropriate instruments for three types of medication-related HL, respectively. These appropriate instruments consistently covered items related to HL dimensions of literacy and comprehension and medication-related information regarding dosing, treatment indication, and side effects/precautions.

CONCLUSION

Of 48 identified instruments mainly derived from disease- or medication-specific studies, the five most appropriate medication-related HL instruments were identified to support clinicians in facilitating patients' correct medication use. Further confirmation to explore the usefulness among these instruments are needed.

Determinants of Medication Adherence for Pulmonary Tuberculosis Patients During Continuation Phase in Dalian, Northeast China

PURPOSE

Medication adherence is crucial for decreasing the burden of tuberculosis, but few relevant studies have been conducted in northeast China. This study aimed to explore the level of medication adherence among pulmonary tuberculosis outpatients and the predictive factors based on the bio-psycho-social medical model.

PATIENTS AND METHODS

A cross-sectional multi-center survey was conducted in four tuberculosis medical institutions in Dalian, northeast China. Medication adherence was measured using the eight-item Chinese version of the Morisky Medication Adherence Scale, which divides adherence into three levels. The independent variables consisted of sociodemographic characteristics, treatment factors, knowledge about TB, mental health, and behavioral characteristics. Descriptive statistics, the chi-square test, and multivariate ordinal logistic regression were applied to analyze the data using Stata/MP 14.0.

RESULTS

Among the 564 eligible participants, 236 (41.84%) and 183 (32.45%) exhibited high and medium medication adherence, respectively, but 145 (25.71%) exhibited low medication adherence. Multivariate ordinal logistic regression showed that patients who were older (OR: 1.02, p=0.013) were employed (OR: 1.61, p=0.011), had better tuberculosis knowledge (OR: 1.34, p<0.001), and did not consume alcohol (OR: 1.84, p=0.032) exhibited higher medication adherence. However, patients who did not follow their doctors' advice to take adjuvant drugs (OR: 0.44, p=0.001), had a history of TB treatment (OR: 1.76, p=0.009), experienced adverse drug reactions (OR: 0.65, p=0.017), experienced stigma (OR: 0.67, p=0.032), and needed supervised treatment (OR: 0.66, p=0.012) exhibited lower medication adherence.

CONCLUSION

Tuberculosis patients' medication adherence was not very high and it was influenced by diverse and complex factors involving sociodemographic characteristics, treatment factors, knowledge about TB, mental health, and behavioral characteristics.
