Abstract
The Clock Drawing Test (CDT) has been widely used as an executive function and visuoconstructive measure. However, scoring systems that describe planning and organization strategies in clock drawing does not exist. The objective of the present article is to map, describe and classify the different planning and organizing strategies of clock drawing. 77 older volunteers without cognitive complain. CDT execution's process and time were registered. Drawings were scored with semi-quantitative (Sunderland et al., 1989) and qualitative (Parsey and Edgecombe et al., 2011) systems. The strategies of clock drawing test drawing were classified and associated to sociodemographic data, scores of the qualitative scoring system and executive function tests (Rey Complex Figure Test; Cubes – WAIS-III). The results showed diversity in the patterns of strategies of drawing. The most frequent strategies were a general sequence (circle-number-center-hand) and a numerical sequence which followed a sequential pattern of increasing numerical order. On the other hand, better results in executive function measures were more associated with circle-number-center-hand (general sequence) and quadrant (numerical sequence) strategies. This new method of classification complements the previous existing semi-quantitative and qualitative scoring criteria.
