Összefoglaló	The PSDQ is a 40-item questionnaire measuring multidimensional physical self-concept—how individuals perceive and evaluate themselves across 11 physical domains including strength, endurance, body appearance, sports competence, and fitness. Developed by Marsh and colleagues in 1994, the PSDQ has become the leading instrument for assessing physical self-concept in youth and adult athletes and is valuable for understanding body image, exercise motivation, and psychological wellbeing.	The SCI is a 13-item questionnaire measuring general, trait-level confidence in sport ability—the athlete's habitual belief in their capability to execute skills and perform well in their sport. Developed by Vealey in 1986, the SCI is one of the most widely used instruments for assessing athlete self-confidence and predicting competitive success and psychological wellbeing.
