Përmbledhja	The Pittsburgh Sleep Quality Index (PSQI) is a comprehensive self-report questionnaire developed by Buysse and colleagues in 1989 to assess sleep quality and sleep disturbances. The PSQI comprises 19 items aggregated into seven components that evaluate sleep duration, sleep efficiency, sleep disturbances, daytime dysfunction, and use of sleep medications. It is one of the most widely used instruments for both clinical sleep assessment and sleep research.	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.
