NOROPSIKIYATRI ARSIVI-ARCHIVES OF NEUROPSYCHIATRY, cilt.47, sa.2, ss.91-95, 2010 (SCI-Expanded)
Objective: Clock Drawing Test (CDT) has been widely used in dementia screening as a practical and valid tool assessing various neuropsychological domains. Many scoring systems requiring different instructions and methodologies were proposed for CDT and there are several studies comparing the diagnostic accuracy of these methods. However, there is still no clear agreement on which one is the best for clinical and research settings. The present study aimed to investigate the psychometric properties of the Turkish versions of the three most commonly used CDTs (Shulman's, Sunderland's and Watson's CDTs) and to compare their diagnostic accuracy with each other and Mini Mental State Examination (MMSE).
