Abstract
INTRODUCTION: Organized sport promotes physical and psychological health in adolescents, improving emotional regulation, self-efficacy and resilience, which are essential for preventing addiction. This study validates an adapted ESTUDES scale for measuring consumption and risk perception in young athletes. METHOD: Descriptive cross-sectional study with 914 adolescent footballers from Jaén and Granada (aged 12-18). The ESTUDES 2023 questionnaire (20 items on tobacco, alcohol, cannabis, gambling, and risk perception) was adapted, applying exploratory and confirmatory factor analysis. RESULTS: Five factors were identified, explaining 73.47% of the variance: tobacco use, alcohol use, gambling, cannabis use, and risk perceptions. Reliability was adequate (α = 0.863) with satisfactory fit indices (CFI = 0.920; RMSEA = 0.060). The highest correlations appeared between tobacco and alcohol (0.564), while risk perceptions showed negative relationships with all types of consumption. CONCLUSION: The scale demonstrated adequate validity and consistency, constituting a useful tool for assessing addictive behaviors and designing preventive programs for adolescent athletes.
