Muhtasari	The Pediatric Quality of Life Inventory (PedsQL), developed by James Varni in 2001, is a validated, evidence-based patient-reported outcome measure assessing health-related quality of life in children and adolescents aged 2–18 years. Available in generic core scales and disease-specific modules, it measures physical, emotional, social, and school functioning, making it ideal for clinical research, outcome measurement, and population health surveillance.	The School Engagement Scale (SES) conceptualizes and measures school engagement as a multidimensional construct encompassing behavioral engagement (participation in academic and school activities), emotional engagement (motivation, interest, sense of belonging), and cognitive engagement (willingness to exert effort, persistence in learning). Developed by Fredricks, Blumenfeld, and Paris (2004), school engagement is a critical predictor of academic achievement, grade retention, and high school dropout.
