Codes and Frequencies
For sample children, TBILOSTCONEV reports whether they have ever been knocked out or lost consciousness due to a blow or jolt to the head. If necessary, interviewers prompted respondents to "[p]lease think about all head injuries, for example, from playing sports, car accidents, falls, or being hit by something or someone."
TBILOSTCONEV is collected as part of an emerging content section introduced on the 2020 questionnaire about lifetime head injuries or concussions. For more variables on head injury or concussion, as well as other injury-related variables, please see INJANY.
