Development and Reliability and Validity Testing of a Health Literacy Assessment Scale for Nursing Assistants

Condition(s) studied

Investigational drug(s) / intervention(s)

Health Literacy Questionnaire for Nursing Assistants: A structured self-report questionnaire designed to assess health literacy among nursing assistants(caregivers ) working in medical institutions, based on their job characteristics and caregiving needs. The scale is developed through literature review, semi-structured interviews, and two rounds of Delphi expert consultation, and validated via a multicenter questionnaire survey. Psychometric evaluation includes item analysis, exploratory and confirmatory factor analysis, content validity index, average variance extracted, composite reliability, Cronbach's α, split-half reliability, and test-retest reliability (14-day interval).

Study summary

The goal of this observational study is to develop and evaluate a health literacy assessment scale for caregivers (nursing assistants) working in medical institutions, based on their job characteristics and caregiving needs. The main questions it aims to answer are:

Can the newly developed scale validly and reliably measure health literacy among caregivers in healthcare settings?

What is the current level of health literacy among caregivers, and which factors are associated with it?

Caregivers working in medical institutions (aged 18-65, with at least 3 months of caregiving experience) will complete survey questionnaires about their health literacy, health behaviors, and job characteristics. A subset will repeat the survey 14 days later to assess test-retest reliability.

Eligibility

Primary outcome measure(s)

• Structural validity of the Health Literacy Assessment Scale for Nursing Assistants — At completion of data analysis (approximately 3 months after the end of the large-sample survey).
  The structural validity of the newly developed Health Literacy Assessment Scale for Nursing Assistants will be evaluated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), based on factor loadings and model fit indices.
• Content validity of the Health Literacy Assessment Scale for Nursing Assistants — At completion of data analysis (approximately 3 months after the end of the large-sample survey).
  The content validity of the newly developed Health Literacy Assessment Scale for Nursing Assistants will be evaluated using the Content Validity Index (CVI).
• Convergent validity of the Health Literacy Assessment Scale for Nursing Assistants — At completion of data analysis (approximately 3 months after the end of the large-sample survey).
  The convergent validity of the newly developedHealth Literacy Assessment Scale for Nursing Assistants will be evaluated using Average Variance Extracted (AVE).
• Internal consistency reliability of the Health Literacy Assessment Scale for Nursing Assistants — At completion of data analysis (approximately 3 months after the end of the large-sample survey).
  The internal consistency reliability of the newly developed Health Literacy Assessment Scale for Nursing Assistants will be evaluated using Cronbach's α coefficient, Composite Reliability (CR), and split-half reliability.
• Test-retest reliability of the Health Literacy Assessment Scale for Nursing Assistants — 14 days after the initial survey.
  The test-retest reliability of the newly developed Health Literacy Assessment Scale for Nursing Assistants will be evaluated using the Intraclass Correlation Coefficient (ICC) at a 14-day interval.
