abstract="OBJECTIVE: The study objective was to determine whether number of concussions would  affect symptom improvement following cognitive rehabilitation (CR) interventions. <br><br>METHOD: Service members (N = 126) with concussion history completed a 6-week  randomized control trial of CR interventions. Participants were stratified based on  self-reported lifetime concussion frequency. Outcome measures included the Paced  Auditory Serial Addition Test (PASAT), the Global Severity Index (GSI) from the  Symptom Checklist-90-Revised, and the Key Behaviors Change Inventory (KBCI). <br><br>RESULTS: Mixed-model analyses of variance revealed a significant main effect for  time on cognitive, psychological, and neurobehavioral functioning. A significant  main effect for the number of concussions was observed for GSI and KBCI, but not  PASAT. Interactions between the number of concussions and time were not significant  for any of the outcome variables. <br><br>CONCLUSIONS: Over the 6-week interval,  improvements were found for all participants across all outcome measures. Number of  concussions did not affect improvements over time.<p /> <p>Language: en</p>",
