Even though the full ACL-RSI scale is relatively short, item redundancy is clearly present in this questionnaire. Later on, a shorter version of the ACL-RSI scale has been developed (Webster & Feller 2018<\/a>). In each of the 3 domains, questions who were redundant were removed. Even though the scale was reduced by half, consisting of 6 items, the reliability and validity was not sacrificed. In other words, the psychometric properties of the scale remained the same. Therefore, this short version was found to be a robust substitute for the full version of the ACL-RSI scale for discriminating between patients who return to sport or not, and predicting return to sport outcomes.<\/p>\r\n \r\nValidity and Reliability<\/h3>\r\nWebster et al. (2008)<\/a> report that with a Cronbach's alpha of 0.92, the full ACL-RSI scale demonstrated satisfactory reliability. The shortened version maintained strong reliability (Cronbach\u2019s alpha = 0.92). Factor analysis supported a single-factor structure explaining 71% of the total variance. Scores on the shortened scale significantly distinguished between patients who had returned to sport and those who had not. At six months post-injury, both the full and short versions demonstrated fair to good predictive validity for return to sport at 12 months (full version: AUC = 0.77 [95% CI: 0.7\u20130.8]; short version: AUC = 0.75 [95% CI: 0.7\u20130.8]) (Webster & Feller 2018<\/a>).\r\n\r\n \r\n
Scoring and Interpretation<\/h3>\r\nEach item on the ACL-RSI is rated on a scale from 0 to 100, in 10-point increments. A total score between 0 and 100 is calculated by adding and averaging the scores for each item. Greater psychological preparation is indicated by higher scores."},{"acf_fc_layout":"content","background_color":"none","content_alignment":"left","content_editor":"
