The aim of this study was to assess executive functions of obese individuals with binge eating disorder.
Thirty-eight obese individuals with binge eating disorder were compared to thirty-eight obese controls without binge eating disorder in terms of their executive functions. All individuals were assessed using the following instruments: Digit Span, Trail Making Tests A and B, Stroop Test and the Wisconsin Card Sorting Test. In addition, four subtests from the Behavioral Assessment of the Dysexecutive Syndrome Battery were also used, namely the Zoo Map Test, the Modified Six Elements Test, the Action Program Test and the Rule Shift Cards Test.
When compared to obese controls, obese individuals with binge eating disorder presented significant impairment in the following tests: Digit Span backward, Zoo Map Test, Modified Six Elements Test, and Action Program Test. Subjects with binge eating disorder also showed significant more set shifting and perseverative errors in the Wisconsin Card Sorting Test. In other measures such as the Digit Span Forward, the Trail Making Test, the Stroop Test and the Rule Shift Cards Test, obese subjects with binge eating disorder did not differ significantly from obese subjects without binge eating disorder.
These results suggest that, in the present sample, obese individuals with binge eating disorder presented executive deficits, especially impairments relating to problem-solving, cognitive flexibility and working memory.
本研究旨在评估患有暴食症的肥胖个体的执行功能。
将 38 名患有暴食症的肥胖个体与 38 名无暴食症的肥胖对照者进行比较，评估他们的执行功能。所有个体均采用以下工具进行评估：数字跨度、连线测试 A 和 B、斯特鲁普测试和威斯康星卡片分类测试。此外，还使用了行为执行障碍评估成套测验的四个子测验，即动物园地图测验、改良六元素测验、动作程序测验和规则转换卡片测验。
与肥胖对照组相比，患有暴食症的肥胖个体在以下测试中表现出明显的损伤：数字跨度倒背、动物园地图测验、改良六元素测验和动作程序测验。暴食症患者在威斯康星卡片分类测试中还表现出明显更多的转换和持续错误。在其他措施方面，如数字跨度正背、连线测试、斯特鲁普测试和规则转换卡片测验，患有暴食症的肥胖个体与无暴食症的肥胖个体之间没有显著差异。
这些结果表明，在本样本中，患有暴食症的肥胖个体存在执行功能缺陷，尤其是在解决问题、认知灵活性和工作记忆方面存在损伤。
