Muhtasari	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.	The MTQ48 is a 48-item instrument measuring mental toughness—the capacity to perform well under pressure, persist through adversity, maintain emotional control, and sustain commitment toward goals. Developed by Clough, Earle, and Sewell in 2002, the MTQ48 operationalizes mental toughness across four dimensions (the '4Cs': Control, Commitment, Challenge, and Confidence) and has become widely adopted in sport psychology, talent development, and organizational psychology for identifying and developing psychological resilience.
