PROMIS II participants who completed the survey on the computer were first administered items using the computer adaptive test (CAT) format. After the CAT items were administered, the survey administered any short form items that had not been selected by the CAT. As a result, participants were administered different numbers of items. For the purpose of the current study, we analyzed missingness in the short form items only, as these items were administered to all participants. The numbers of short form items for each measure are listed in the table.
