Muhtasari	The Positive and Negative Affect Schedule (PANAS) is a brief, efficient self-report measure of mood and emotional affect. Developed by Watson, Clark, and Tellegen in 1988, it assesses two independent dimensions: positive affect (enthusiasm, attentiveness, interest) and negative affect (distress, anxiety, anger). The 20-item standard version is one of the most widely used instruments for measuring emotion in research and clinical contexts.	The Center for Epidemiologic Studies Depression Scale (CES-D) is a 20-item self-report instrument for measuring depressive symptoms in the general population. Developed by Lenore Radloff in 1977, the CES-D was designed for epidemiological research to rapidly identify depression in community samples. It remains a widely used measure in public health, aging research, and longitudinal cohort studies worldwide.	The Hospital Anxiety and Depression Scale (HADS) is a 14-item self-report instrument measuring anxiety and depression symptoms in medically ill populations. Developed by Zigmond and Snaith in 1983, the HADS was specifically designed for hospital and general medical settings where somatic symptoms of medical illness may confound assessment. It remains the standard anxiety-depression measure in medical, oncology, and cardiac populations worldwide.
