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

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.
