The Clock Drawing Test (CDT) is a sensitive and simple instrument for assessing dementia. Although the CDT is commonly used clinically, there is no consensus in its scoring and validation in Taiwan. This cross-sectional study uses the theoretical framework of directed attention and is designed to evaluate the Rouleau's scoring system of the CDT. Participants include 100 early AD participants and 100 age-matched normal controls in Taiwan. Four of directed attention impairment indicators are applied, such as perseveration, impulsivity, irritability, and executive dysfunction. The Cognitive Abilities Screening Instrument (CASI) and the Clinical Dementia Rating (CDR) are used to assess participants' global cognition and dementia severity respectively. The DSM-VI is the dementia diagnosis standard. The AD group has a CDR score equal to 0.5 or 1, while the age-matched normal controls CDR 0. The scores of CDT under command condition significantly correlate with those of the CASI and the Attentional Function Index (the executive function measurement). The most comment error types of the CDT are spatial errors (62%), stimulus-bound errors (11%), and perseveration errors (6%). Stimulus-bound and perseveration errors are associated with directed attention impairments. The mean scores of CDT under command condition are significantly lower than those under copy condition in both groups (AD: command means=7.18 ± 5.36 vs. copy means=10.28 ± 4.86; control: command means=11.74 ± 4.06 vs. copy means=13.24 ± 2.77). Additional information will be illustrated in ANOVA tables among questionable AD and mild AD groups as well as controls. The intra-rater agreement is 95% between two trained raters. In conclusion, the CDT is a simply understood, unoffending, and culturally fair instrument with acceptable validity and reliability when used in Taiwanese dementia and normal elderly populations.
