E. Dykens, THE DRAW-A-PERSON TASK IN PERSONS WITH MENTAL-RETARDATION - WHAT DOESIT MEASURE, Research in developmental disabilities, 17(1), 1996, pp. 1-13
As a widely used, easy-to-administer, and nonthreatening task, the Dra
w-a-Person (DAP) holds particular promise as a nonverbal index of inte
lligence in persons with mental retardation. The DAPs of 108 adolescen
ts and adults with mental retardation were reliably scored using Nagli
eri's cognitive and emotional disturbance scoring systems. Contrary to
expectations, visual-motor skills emerged as the best predictor of DA
P cognitive scores. Intelligence was correlated with DAP scores, but h
ad considerably less predictive value than visual-motor skills. DAP em
otional indicator scores were only modestly associated with social ada
ptation; even less support was found linking DAP emotional indicators
to psychopathology. Findings point to considerable caution in using th
e DAP as an index of intelligence or as a screen for adjustment proble
ms or specific psychopathology. Although related to intelligence, this
popular task seems predominantly to measure visual-motor development
in adults with mental retardation.
