Background of study: Self-confidence is a critical psychological factor that influences athletic performance, particularly in Paralympic sports where athletes encounter both physical and mental challenges. Aims and scope of paper: This study aims to examine the influence of social support (namely coach, family, and peer support) on the self-confidence of Paralympic weightlifting athletes. Methods: A quantitative survey design was employed, involving athletes selected through purposive sampling. Data were collected using a structured questionnaire based on a five-point Likert scale. The data were analyzed using descriptive statistics, Pearson correlation, and multiple linear regression. Results: The findings indicate that all variables are in the high to very high category, with coach support demonstrating the highest mean score, followed by self-confidence and peer support. Family support shows relatively lower scores, particularly in emotional support during failure or injury. Correlation analysis reveals that coach and peer support have strong positive relationships with self-confidence, while family support shows a moderate relationship. Regression results confirm that all three variables significantly predict self-confidence, with coach support emerging as the most dominant factor. Conclusion: This study concludes that a multidimensional social support system (particularly coach support) plays a critical role in shaping self-confidence among Paralympic weightlifting athletes. The integration of coach, peer, and family support significantly enhances athlete self-efficacy, highlighting the importance of a holistic psychosocial environment to sustain confidence and competitive resilience in elite disability sports.
