Objectives To develop an interactive voice response ( IVR ) version of the Late‐Life Function and Disability Instrument Computer Adaptive Test ( LLFDI ‐ CAT ) and to evaluate its reliability and acceptability in older adults. Design The IVR system was embedded within the LLFDI ‐ CAT program. To test the test–retest reliability and concordance of the IVR version of LLFDI ‐ CAT with the telephone interviewer form ( TIF ), participants received the two versions of the LLFDI at baseline and at 1‐week follow‐up. Setting Community. Participants Community‐dwelling adults aged 65 and older (N = 50). Measurements The LLFDI is a self‐reported outcome measure developed to assess function and disability in older adults. Results The IVR version of the LLFDI ‐ CAT showed acceptable overall test–retest reliability (intraclass correlation coefficient ( ICC ) = 0.79–0.80) and concordance ( ICC = 0.74–0.97) with the TIF . Although most participants preferred the TIF , the majority did not find the IVR version more difficult to use. Conclusion The IVR version of the LLFDI ‐ CAT achieved reliability levels that were comparable with those of the TIF version. Future work is needed to improve the IVR design to better fit older adults’ needs and preferences.
