概要	The Consumer Assessment of Healthcare Providers and Systems (CAHPS) is a family of evidence-based surveys developed by the Agency for Healthcare Research and Quality (AHRQ) beginning in 1995. It systematically measures patient experiences across diverse healthcare settings including hospitals, ambulatory clinics, and home health agencies, capturing dimensions critical to care quality from the patient perspective.	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.
