OSU TBI-ID
Definition
The OSU TBI Identification Method-Short Form is a structured interview developed using recommendations from the CDC for the detection of and history of exposure to TBI. It was designed to elicit self- or proxy-reports of TBI occurring over a person’s lifetime. The OSU TBI-ID-SF uses an interview methodology based on the original longer version, but only measures selected summary indices.
The OSU-TBI-ID method is a means of identifying possible TBIs that may have been previously undiagnosed.
To avoid biases created by terminology used, the interview first elicits recall of all possible head or neck injuries through a series of queries tapping possible causes of TBI. This first step is critical for obtaining a complete history, and should not be interrupted by probing for more details at this stage. After all possible injuries have been elicited, the interviewer goes back to obtain more information about the injuries. For these injuries, the occurrence and length of loss of consciousness is probed. If there is no loss of consciousness, the presence of altered consciousness is probed. Age is also determined for any injuries reported. The final step involves identifying individuals who have experienced a period of time in which they have sustained multiple blows to the head.
Using the structured elicitation method of the OSU TBI-ID-SF, multiple dimensions of history are available, including number of injuries with LOC, number of injuries with LOC>30 minutes, age at first TBI, whether there was an injury with LOC before the age of 15, worst injury and repeated impacts to the head.
The following steps are performed to obtain input information used in each of the TBI ID variables.
First, the length of loss of consciousness as well as whether a person was dazed are classified into the following categories. This is done for each injury listed, excluding the index injury.
- No LOC
- Unknown Duration
- Dazed
- Less than 30 minutes
- 30 minutes to 24 hours
- More than 24 hours
Next, using a person’s age, it is determined whether each injury occurred before, concurrent with, or after a person’s index injury.
Finally, using the combination of length of loss of consciousness and injury timing, aggregate counts of the TBI ID variables are calculated.

Details
This is a structured interview to detect lifetime history of TBI. It is not designed to be administered as a paper/pencil questionnaire.
Individuals are not directly asked about whether they had a traumatic brain injury, because of a tendency for misinterpretation of this and similar terms.
Many people have had multiple brain injuries in their life. We want to make sure we capture all injuries. For this reason, the first part of the interview is critical to obtaining information on all possible injuries. It should not be interrupted by probing for details, because that would disrupt the flow of recall.
Step 1: Any injuries to head or neck
The first time the OSU TBI-ID is administered, the five questions about head or neck injuries should be prefaced with “In your lifetime, have you ever…”. During subsequent administrations, the five questions about head or neck injuries should be prefaced with “Since we last spoke with you on ‘last successful follow-up date’, have you…”. When asking about head or neck injuries since the last follow-up, do not disregard any new ‘lifetime’ injuries if reported.
Injuries do not have to have been diagnosed or treated by a physician or other health professional.
Do NOT include the index injury (the TBI that brought them to your facility).
Step 2: Additional Details
When asking about the duration of LOC, participants should be encouraged to use their best guess and only code ‘5 - Positive Loss of Consciousness, Duration Unknown’ when participant is truly unable to estimate the duration of LOC.
If a participant reports a TBI with loss of consciousness of an unknown duration, data collector should do some additional probing to assist the participant with narrowing down the time frame. For example, if the person awakened at the scene, then it is likely that LOC was less than 30 minutes. If the person awakened while already hospitalized, but it was still the day of the injury, then LOC is likely 30 minutes to 24 hours, etc. After probing using various anchors, then the next step would be to offer the individual the choice regarding the three time periods. If the person still does not know, then the time frame should be coded as “5-Positive Loss of Consciousness, Duration Unknown”.
If a range is given for age, record the midpoint of the range given.
Passing out from alcohol or marijuana use should not be considered a LOC. Most people will pass out before they are able to drink enough alcohol to lose consciousness. However, someone with severe alcoholism may be able to drink enough alcohol to lose consciousness. Additional probing may be necessary to differentiate between an episode of passing out, and a true LOC.
Step 3: Multiple Mild Injuries:
Some individuals have gone through periods in their life when they have sustained multiple mild TBIs, and they cannot distinguish between them. They usually describe such a period as a ‘blur’. For example, they may have been victims of abuse, played football, etc. If the individual is unable to distinguish between these injuries, treat that period in the person’s life as one injury. Ask the person to indicate the longest period that he/she was knocked out. For age, first ask the age range of the time period, then see if you can help them determine where the longest LOC happened in that time frame. If not known, use the midpoint of the age range.
- If participant reports engaging in an activity that they had repeated head impacts, but had only one event that they were knocked unconscious, record this event under Step 2, and record the ongoing activity under Step 3.
- If a participant reports a period of repeated injuries at step 2 without a specific event, this should be included in Step 3.
- If the participant is still engaged in an activity that they reported multiple repeated impacts to the head, use the age at the time of the interview as the “end” age.

Characteristics
The OSU TBI-ID variables replaced the History of TBI variables.
On 1/1/2015 Step 3 was added which asks “(In your lifetime)… or (Since we last spoke with you on last successful follow-up date)… have you (ever) had a period of time in which you experienced multiple, repeated impacts to your head (e.g. history of abuse, contact sports, military duty)?”
On 7/1/2023 a coding option of “Yes” or “No” was added to Step 3 to capture a response in addition to the already existing fields that capture reasons of repeated injuries.
On 1/15/2024 the OSU-TBI-ID was added to Form 1 Data Collection. Coding categories were also added to Step 2 and 3 to replace open text fields.
The error for participants who reported having had a prior TBI (head or neck injury reported), but did not have an entry in the TBI ID table, and who died prior to clarifying this error was removed.
