Effects of Psychological Interventions on the Prevention of Sports Injuries: A Meta-analysis

Abstract

Background: Studies have shown that preventive psychological interventions can reduce the occurrence of sports injuries. Purpose: To systematically evaluate the published literature on the effects of psychological interventions on rates of sports injuries and propose a set of psychological interventions to reduce such injuries. Study Design: Systematic review; Level of evidence, 1. Methods: A total of 11 randomized controlled trials and intervention control trials involving 1287 participants were included. A random-effects model was used to analyze the data. Pooled results were expressed as effect sizes and 95% CIs. Bias and heterogeneity among the studies were assessed, and sensitivity and subgroup analyses were performed. Results: Meta-analysis suggested that preventive psychological interventions effectively prevented the occurrence of sports injuries (effect size = –0.55; P < .001), although the studies showed substantial heterogeneity ( I 2 = 94.2%; P < .001), which could not be attributed to specific variables. Nevertheless, sensitivity analysis suggested that overall results were reliable. No significant risk of publication bias was found. Conclusion: Preventive psychological interventions moderately reduced the risk of sports injuries. Risk screening also significantly reduced the risk of sports injuries. These interventions should focus on cognitive behavior and be administered in 1 to 6 sessions over 7 to 12 weeks for 60 minutes per session.
