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.
道路事故和摔倒常常导致惯用手受伤；然而，很少有研究评估非惯用手是否会混淆纸笔评估。本研究使用平衡的被试内设计，使用 154 名本科生的右手和左手评估 Rey 复杂图形测试 (RCFT) 的复制准确性。使用 Briggs 和 Nebes（1975）对 Annett 手性问卷的修订来确定手性。两名独立评分者使用客观的评分标准（Meyers 和 Meyers，1995），评分者之间具有高度的可靠性。表现差异在统计学上但没有临床意义上显著。非优势手和优势手的表现与标准数据没有差异：使用非优势手的人中有 78.9%的人得分高于损伤截断分数，而使用优势手的人中有 83.7%的人得分高于损伤截断分数。如果一个人的优势手受损，那么在 RCFT 上使用非优势手的表现可能会产生在标准范围内的分数，并且不会错误地暗示神经心理障碍。
