Key outcome variables from the follow-up instrument.

Indicator	Survey questions	Specifications
Disability score	WHODASa 2.0’s shortened form consists mainly of 12 questions capturing the following domains: understanding and communicating; getting around; self-care; getting along with people; life activities; and participation in society. Response options: 0=No Difficulty, 1=Mild Difficulty, 2=Moderate Difficulty, 3=Severe Difficulty, 4=Extreme Difficulty or Cannot Do.	Scores are calculated for each subscale by adding the points from each response. The minimum and maximum total scores are 0-48, where higher scores indicate higher levels of disability.
Perceived return to preinjury activity or “normal life”	As of today, do you consider yourself to have returned to your normal life or to doing your usual activities your injury? Response options: Yes; No.	This question is intended to capture whether the participant has returned to their usual activities as they see it. Participants may consider themselves to have returned to usual activities or normal life because of or despite using an assistive device, whereas other participants may consider themselves not back to “normal” life if they have to use a device or rely on a modification to their physical space. Because this tool is focused on activities and participation, we define “return to normal life” as being able to do the things one was able to do before their injury.
