The linking functions revealed the floor and ceiling effects that exist for the different scales, with CPS and CPS2 measuring more-severe cognitive impairment while the MoCA 5-min was better suited to measure mild impairment.Ĭonclusions: We provided score conversions between MoCA 5-min and CPS/CPS2 within a large cohort of Hong Kong older adults with mild physical or cognitive impairment. At the higher end, a CPS score of 3 (moderately impaired) and a CPS2 score of 5 (moderately impaired Level-2) corresponded to MoCA 5-min scores of 0 and 1, respectively. A CPS or CPS2 score of 0 (intact cognition) corresponds to MoCA 5-min scores of 24 and 25, respectively. Results: 3,543 participants had valid data on both scales 66% were female and their average age was 78.9 years (SD = 8.2). We performed equipercentile linking with bivariate log-linear smoothing to establish equivalent scores between the two scales. Each participant's cognitive performance was assessed using CPS, CPS Version 2 (CPS2), and MoCA 5-min. The program used the interRAI-Check Up instrument for needs assessment and service matching between 20. Methods: We included individual-level data from persons who participated in a home- and community-based care program for older people with mild impairment in Hong Kong.

This study linked scores from the Montreal Cognitive Assessment-5 min (MoCA 5-min) to the interRAI cognitive Performance Scale (CPS), commonly adopted tools in clinical and long-term care settings, respectively. 2Department of Social Work and Social Administration, The University of Hong Kong, Hong Kong, SAR Chinaīackground: Bridging scores generated from different cognitive assessment tools is necessary to efficiently track changes in cognition across the continuum of care.1Centre for Educational Measurement, University of Oslo, Oslo, Norway.Björn Andersson 1 † Hao Luo 2 * † Gloria H.
