Objectives:To assess the feasibility, acceptability, and psychometric properties of the self-report versionof the interRAI Check-Up (CUSR).Design:Cross-sectional study of participant ratings of item content and difficulty completing the CUSR.Participants were also randomly assigned to complete the assessment by themselves or with help from alay interviewer.Settings and Participants:A total of 184 older adults from diverse backgrounds, served by 6 Canadianorganizations in Ontario and Nova Scotia were recruited. Settings ranged from retirement communitiesfor healthy older adults to assisted living facilities.Measures/Methods:Time to complete the interRAI CUSR was tracked automatically. Participants self-reported on what items they wanted to have modified, added, or deleted. The also rated whetheritems were embarrassing or difficult to complete. Psychometric properties were examined between the 2approaches to completion and were benchmarked against existing reports on psychometric properties ofclinician-led home care assessments.Results:The interRAI CUSR takes about 28 minutes to complete with both self-administered and layinterviewer approaches. The convergent validity and reliability of CUSR is comparable to those ofclinician-based assessments like the Resident Assessment Instrument-Home Care. Most participants hadno difficulty completing the assessment, and none rated the task as very difficult. Poor self-rated healthand difficulty with phone use were predictive of any difficult in completing the assessment in a multi-variate logistic regression. Most participants reported that CUSR adequately described their health needs,but arthritis, hypertension, and mental health issues were identified as items to be added by participants.Conclusions and Implications:The CUSR is an appropriate, feasible assessment system with good psy-chometric properties for use with general populations, including primary care, community services, andpatient-reported outcome measurement studies. Interoperability with other interRAI assessments makesit an ideal system to use to obtain a longitudinal view of the person’s needs over time
