    Abstract:
    Road accidents and falls often result in injury to the dominant hand; however, few studies have evaluated whether the use of the nondominant hand confounds pen and paper assessments. This study used a counterbalanced within-subjects design to assess the copy accuracy on the Rey Complex Figure Test (RCFT) of 154 undergraduates using both their right and left hands. Handedness was determined using Briggs and Nebes's (1975) revision of Annett's Handedness Questionnaire. Two independent scorers used objective scoring criteria (Meyers & Meyers, 1995) with high interscorer reliability. Performance differences were statistically but not clinically significant. Nondominant- and dominant-hand performances did not differ from normative data: A total of 78.9% scored above the impairment cutoff score using the nondominant hand compared to 83.7% using their dominant hand. In the event an individual's dominant hand is compromised, performance using the nondominant hand on the RCFT could produce scores within the normative range and would not falsely suggest neuropsychological impairment.
