Please choose "unable to do" if you:

  • Would need help from another person to complete the task
  • Would need a wheelchair or scooter to complete the task

PLUS-M™ Items Administered

The items administered by the PLUS-M™ Instrument and the respondent's associated answers are provided below. Questions are presented in the order in which they were administered.

Note: If fewer than items are listed, the CAT achieved a precise score (standard error below ) with fewer questions. If a question has no answer, the respondent elected to skip that question. For questions about the PLUS-M™ Instruments, please see the PLUS-M™ Users Guide.
