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 AIMS is a 10-item questionnaire assessing the degree to which being an athlete is central to an individual's self-concept and identity. Developed by Brewer, Van Raalte, and Linder in 1993, the AIMS has become the standard instrument for measuring athletic identity and is widely used to predict athlete coping responses to injury, career transitions, and retirement.
