What this trial measures

• Behavioral Regulation Assessment for Concussion (BRAC)Gathered at Baseline Visit

  The Behavioral Regulation Assessment for Concussion (BRAC) is a five-item, four-point Likert scale (with values ranging from '0-Never' to '5-Most of the Time') assessment for the frequency of self-reported behavioral regulation behaviors that occurred during the past seven days. Scores range from 0 to 20, with higher scores indicating a better outcome. Likert scale scores are reported for each item, with a higher score indicating greater frequency. An average score for the BRAC is the average of all the scores across the items.

• Expectations of Recovery ScaleGathered at Baseline Visit

  The Expectations of Recovery Scale will be used to measure the effect of positive assurance on recovery. This is a seven-item scale that asks individuals to assess whether they think they will get better soon, return to usual activities/work within the next month, return to the pre-injury performance and to consider what they had been told about their injury and what those closest to them advised. Items within this scale are scored independently of each other, therefore neither higher nor lower scores indicate a better or worse outcome.
