It is essential to spend time helping a respondent recall injuries throughout their lifetime. The OSU TBI-ID is administered via interview, either by telephone or face-to-face. The instructions for administration and scoring are incorporated into the form and are summarized below.
First, a series of five questions is asked about different kinds of injuries experienced or treatment received. The goal in this step is to help the person recall any injuries that involve the head or neck that have occurred over their lifetime. Each injury that is provided spontaneously throughout this series of questioning is recorded in the first column of the table. Don’t ask for more details about each injury in this step. Once all injuries have been recorded, proceed to Step II. If no injuries are recorded, skip Step I and proceed to Step III.
Next, more information is obtained about each injury recorded in the table. Starting with the first injury, ask if they were knocked out or had loss of consciousness (LOC). If yes, ask how long and place a checkmark in the appropriate column of that row (LOC/knocked out: No LOC, <30 min, 30 min-24 hrs, >24 hrs). If no, ask if they were dazed or had a gap in memory from the injury and check the appropriate column of that row (Dazed/Mem Gap: yes/no). Ask how old they were at the time of the injury and record age. Repeat for each injury recorded in the table.
If there is more than one injury with LOC, use the information in the table to determine and record the following:
• How many more?
• Longest knocked out?
• How many >=30 minutes?
• Youngest age?
Finally, you will ask if they have ever lost consciousness from a drug overdose or from being choked. Record the total number of overdose incidents and the total number of choking incidents.
