Substance-dependence is highly associated with executive cognitive function (ECF) impairments. However, considering that it is difficult to assess ECF clinically, the aim of the present study was to examine the feasibility of a brief neuropsychological tool (the Frontal Assessment Battery - FAB) to detect specific ECF impairments in a sample of substance-dependent individuals (SDI). Sixty-two subjects participated in this study. Thirty DSM-IV-diagnosed SDI, after 2weeks of abstinence, and 32 healthy individuals (control group) were evaluated with FAB and other ECF-related tasks: digits forward (DF), digits backward (DB), Stroop Color Word Test (SCWT), and Wisconsin Card Sorting Test (WCST). SDI did not differ from the control group on sociodemographic variables or IQ. However, SDI performed below the controls in DF, DB, and FAB. The SDI were cognitively impaired in 3 of the 6 cognitive domains assessed by the FAB: abstract reasoning, motor programming, and cognitive flexibility. The FAB correlated with DF, SCWT, and WCST. In addition, some neuropsychological measures were correlated with the amount of alcohol, cannabis, and cocaine use. In conclusion, SDI performed more poorly than the comparison group on the FAB and the FAB's results were associated with other ECF-related tasks. The results suggested a negative impact of alcohol, cannabis, and cocaine use on the ECF. The FAB may be useful in assisting professionals as an instrument to screen for ECF-related deficits in SDI.
物质依赖与执行认知功能(ECF)损害高度相关。然而,由于临床上评估 ECF 较为困难,本研究旨在检验一种简短的神经心理学工具(额叶评估测验 - FAB)在物质依赖个体(SDI)样本中检测特定 ECF 损害的可行性。共有 62 名受试者参与了这项研究。30 名符合 DSM-IV 诊断的 SDI 在戒断 2 周后和 32 名健康个体(对照组)接受了 FAB 和其他 ECF 相关任务的评估:数字向前(DF)、数字向后(DB)、Stroop 颜色词测试(SCWT)和威斯康星卡片分类测试(WCST)。SDI 在社会人口统计学变量或智商方面与对照组无差异。然而,DF、DB 和 FAB 测试中 SDI 的表现均低于对照组。在 FAB 评估的 6 个认知领域中,SDI 在 3 个领域存在认知障碍:抽象推理、运动编程和认知灵活性。FAB 与 DF、SCWT 和 WCST 相关。此外,一些神经心理学测试与酒精、大麻和可卡因的使用量相关。总之,SDI 在 FAB 上的表现劣于对照组,并且 FAB 的结果与其他 ECF 相关任务相关。研究结果表明,酒精、大麻和可卡因的使用对 ECF 有负面影响。FAB 可能有助于专业人员作为一种工具,筛选 SDI 中与 ECF 相关的缺陷。
