Reliability and sensitivity of two clock drawing test rubrics as screening measures for mild cognitive impairment

Early identification of mild cognitive impairment (MCI) is critical, as MCI precipitates disability and may be a precursor to major neurocognitive disorder. The Clock Drawing Test (CDT) is a widely adopted screening measure for dementia however it is not known whether paper‐and‐pencil CDT scoring rubrics are sensitive to subtle losses consistent with MCI. We examined the reliability and sensitivity to MCI of two free‐drawn Clock Drawing Test rubrics ‐ the 10‐point Rouleau, and the 20‐point Clock Drawing Interpretation Scale (CDIS) in community‐dwelling older adults.
