Σύνοψη	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 TEOSQ is a 13-item questionnaire measuring achievement goal orientation in sport: the underlying reasons athletes define success and pursue achievement. Developed by Duda and Nicholls in 1992, the TEOSQ has become a cornerstone instrument for understanding athlete motivation, resilience, and response to failure.
