This study investigates the neurobehavioral components involved in Trail Making Test (TMT; Parts A and B) performance and their relation to MMPI-2 measures of anxiety and depression. Consecutive patients (N = 192) referred for a comprehensive neuropsychological evaluation at a U.S. Department of Veterans Affairs (VA) Medical Center comprised the sample.
graphomotor speed and mental shifting were significantly associated with Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) indexes, whereas visual scanning efficiency was not. Graphomotor speed accounted for a substantially greater portion of the variance in TMT performance within impaired than within normal groups. Levels of anxiety and depressive symptoms were unrelated to TMT performance. Implications and directions for future research are discussed.
本研究探讨了连线测试（TMT；A 部分和 B 部分）表现中涉及的神经行为成分及其与明尼苏达多项人格测验第二版（MMPI-2）焦虑和抑郁测量指标的关系。连续患者（N=192）在美国退伍军人事务部（VA）医疗中心进行了全面的神经心理评估，构成了样本。
图形运动速度和心理转换与韦氏成人智力量表第三版（WAIS-III）指数显著相关，而视觉扫描效率则没有。在受损组中，图形运动速度对 TMT 表现的变异解释度明显大于正常组。焦虑和抑郁症状水平与 TMT 表现无关。讨论了对未来研究的影响和方向。
