title: CogSport: reliability and correlation with conventional cognitive tests used in postconcussion medical evaluations.
abstract: OBJECTIVE
  To determine the repeatability of a computerized cognitive test designed to monitor recovery from concussion and assist team physicians make return to play decisions (CogSport). To determine the correlation between CogSport and two conventional neuropsychological tests.
  
  
  METHODS
  Prospective, serial investigation of cognitive function.
  
  
  METHODS
  Professional and semi-professional Australian Football clubs and a university affiliated research institute in Melbourne, Australia.
  
  
  METHODS
  Three-hundred healthy young adults, including 240 elite athletes.
  
  
  METHODS
  Intra-class correlation (ICC) coefficients for CogSport performance measures administered serially. ICC between CogSport performance measures and conventional neuropsychological tests. Normative data for CogSport performance measures.
  
  
  RESULTS
  Measures of psychomotor function, decision making, working memory and learning were highly reliable. Some measures also displayed high correlations with conventional neuropsychological tests of information processing and attention. Preliminary normative data is described.
  
  
  CONCLUSIONS
  CogSport is a highly reliable cognitive function test when administered to healthy young adults and elite athletes. CogSport measures similar cognitive functions as conventional tests used commonly in concussion research.
