The reliability of clock drawing test scoring systems modeled on the normative data in healthy aging and non-amnestic mild cognitive impairment
Original language description
The Clock Drawing Test (CDT) is a commonly used tool in clinical practice and research for cognitive screening among older adults. The main goal of the present study was to analyze the inter-rater reliability of three different CDT scoring systems [by Shulman et al. (1993, 1986), by Babins et al. (2008) and by Cohen et al. (2000)]. We used a clock with a pre-drawn circle. The CDT was evaluated by three independent raters based on the normative data set of healthy older and very old adults and patients with non-amnestic mild cognitive impairment (naMCI) (N = 438; aged 61 to 94). We confirmed a high inter-rater reliability measured by intra-class correlation coefficient (ICC): Shulman ICC = .809, Babins ICC = .894, and Cohen ICC = .862, all p < .001. We found that age and education levels have a significant effect on CDT performance, yet there was no influence of gender. Finally, the scoring systems differentiated between age- and education-matched controls and naMCI: Shulman AUC = .84, Cohen AUC = .71, all p < .001; and a slightly lower discriminative ability was showing by Babins: AUC = .65, p = .012; (p ≤ .01).
