- W2316575066 abstract "PURPOSE:To evaluate the validity of baseline computerized cognitive test performance of a large international group of athletes using test completion and integrity criteria. BACKGROUND: Concussion consensus guidelines recommend athletes undergo pre-season medical evaluation which may include computerized cognitive testing. Detection of subtle cognitive changes after concussion are dependent upon best effort baseline test performance. Determining best effort is not straight forward but may utilize test completion and integrity criteria, and symptom validity checks. METHODS: Participants were contact sports athletes from Australia, USA, UK, and South Africa who had baseline testing using CogState Sport between Jan 2002 and May 2010. The following criteria for valid baselines were considered: (i) ≥ 75% of expected trials were completed for each task, and (ii) integrity criteria for task accuracy and relative speed. The proportion of baseline tests failing each criterion and any one criterion were computed, as were distributions of speed and accuracy for those remaining in order to determine the effect of these criteria on real world likelihood of an athlete obtaining an invalid test (and hence having to repeat their test). RESULTS: Of 17,371 athletes with first baseline tests, 13.9% failed at least one criterion, while 3.4% failed at least one test completion criterion, 12.8% at least one accuracy integrity criterion, and 2.0% failed at least one relative speed criterion. Of the 1761 who failed but were retested 16% failed at least one criterion, and for the 521 retested again 18% failed. Speed and accuracy performances overall were not significantly different in those with valid tests under each of these conditions by specified criteria, though the specific athletes in each differed. CONCLUSIONS: This data suggests that adoption of restricted test completion or integrity criteria can lead to passing some athlete performances who would have failed more expansive criteria. Casting a wider net using test completion and integrity criteria is appropriate in order to ensure that as many individual athletes as possible are flagged at baseline testing as not performing optimally. On average, about 14% of athletes fail baseline integrity criteria and require repeated testing." @default.
