Abstract
Introduction: An anterior cruciate ligament (ACL) injury is a common sport injury. The impact of an ACL injury is high, because it affects mostly people who are working to earn the main income and there is a long period of rehabilitation. The aim of an ACL reconstruction is often to enhance return to sport. Psychological and psychosocial factors play an important role in returning to competitive sport after an ACL injury. There are several indications that cognition, affect and behavior play an important role in the return to sport. The main reason for not returning to sport is fear of re- rupture of the ACL. Other reasons are an unstable knee and pain. Because there was no instrument available for the assessment of these psychological factors, the Anterior Cruciate Ligament - Return to Sport after Injury (ACL-RSI) Questionnaire was developed. This questionnaire measures the emotions, confidence in performance and risk appraisal for return to sport. The ACL-RSI Questionnaire was translated into Dutch. The Dutch version of the ACL-RSI questionnaire has shown to be reliable and valid. The responsiveness (the ability of an questionnaire to detect change over time) of the ACL-RSI questionnaire has not been determined yet. Therefore the purpose of this study was to determine the responsiveness of the Dutch version of the ACL-RSI questionnaire. Material and methods: This was a clinimetric study. The study population consisted of 70 patients, who underwent primary ACL reconstruction between October 2012 and July 2013 and who were active in sports before surgery. All patients received an information letter by mail, which explained the aim of the study. Patients who completed the ACL-RSI Questionnaire and returned it by mail, received the ACL-RSI questionnaire again after approximately 80 days (during this time a change in confidence is expected) along with a Global Rating of Change (GRC) question. By the GRC question the patient was asked whether he believes that a change has occurred in the confidence in the return to sports. The difference score on the ACL-RSI questionnaire between patients with (much) more confidence was compared with the group with unchanged and (much) less confidence by an independent T-test. The responsiveness was measured by the distribution-based method and the anchor-based method. The outcome measures were the Smallest Detectable Change (SDC), the Standarised Response Mean (SRM) and the Minimally Important Change (MIC). The MIC is the best cut-off point on the Receiving Operating Characteristic Curve (ROCcurve) between patients with (much) more confidence and patients with unchanged and (much) less confidence on the global rating of change question. Results: There was a significant difference in the score on the ACL-RSI questionnaire between patients with (much) more confidence and the group with unchanged and (much) less confidence (P=0,002). The SRM was 0.29. This is found to be a low responsiveness. The SDC was 17.5. The MIC was 0.83 with a sensitivity of 0.79 and a specificity of 0.70. Discussion: Because the responsiveness of the ACL-RSI questionnaire was found to be low, this instrument is not suitable for the measurement of changes in confidence in the return to the sport after ACL reconstruction. However, the ACL-RSI has shown to be a valid and reliable measure to assess the confidence in the return to the sport at one moment. Further research should be performed to develop a method that can detect changes in confidence in return to sport.
