Σύνοψη	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.	The Epworth Sleepiness Scale (ESS) is a brief, validated self-report instrument developed by Johns in 1991 to quantify the level of daytime somnolence or excessive daytime sleepiness. The ESS comprises eight items asking patients to rate the likelihood of dozing off in various everyday situations. It is the most commonly used standardized measure of daytime sleepiness in clinical practice and research.
