Tóm tắt	Health literacy scales are validated self-report instruments designed to measure the capacity of individuals to access, understand, appraise, and communicate health information to maintain or improve health. The Rapid Estimate of Adult Literacy in Medicine (REALM) and Test of Functional Health Literacy in Adults (TOFHLA) are commonly used variants assessing functional health literacy in clinical populations. Health literacy measurement identifies patients at risk for poor health outcomes and guides communication simplification.	The Patient Health Questionnaire-2 (PHQ-2) is an ultra-brief, validated two-item screening instrument developed by Kroenke and colleagues in 2003 to identify major depression in primary care and medical populations. The PHQ-2 assesses the two cardinal symptoms of depression (depressed mood and anhedonia) over the past two weeks using a 0-3 frequency scale. It is the shortest validated depression screening tool enabling routine use in time-constrained clinical settings.
