概括
患有神经性厌食症 (AN) 的女性的男性兄弟姐妹在认知同情和思想理论方面表现出缺陷,特别是在因果推理方面. 这些发现表明,推断困难可能表明家庭对AN的脆弱性.
科学领域:
- 认知神经科学是一种认知神经科学.
- 精神病学是一个精神病学.
- 遗传学 是一个遗传学.
背景情况:
- 神经性厌食症 (AN) 与认知和情绪缺陷有关,包括同情心和心理理论 (ToM) 的受损.
- 这些特征在AN个体中得到了记录,但它们在未受影响的男性兄弟姐妹中存在,这些兄弟姐妹具有共同的风险因素,人们对这些特征的理解较少.
- 这项研究检查了与受影响的姐妹和一般人口 (GP) 对照相比,患有AN (bAN) 的女性的男性兄弟姐妹是否表现出中间的认知情感特征.
研究的目的:
- 为了研究精神性厌食症妇女的未受影响的男性兄弟姐妹的认知情感特征.
- 为了将男性兄弟姐妹 (bAN) 的这些特征与受影响的姐妹和一般人口对照进行比较.
- 识别家庭对AN脆弱性的潜在社会认知预测因素.
主要方法:
- 评估了31名bAN,31名GP和31名受影响的姐妹,使用自我报告问卷 (同理心率,多伦多亚历克西西米亚量表) 和计算机化ToM任务 (基于故事的同理心任务 (SET),阅读眼睛中的思维任务).
- 由于数据分布异常,使用非参数测试进行组间比较.
- 采用二进制后勤回归来确定社会认知变量是否预测了群体成员资格.
主要成果:
- 男性兄弟姐妹 (bAN) 在认知同情和思维理论方面的得分明显低于GP对照.
- 在SET任务中,在因果推断 (SET-CI),情感归因 (SET-EA) 和意图归因 (SET-IA) 中发现了特定的缺陷.
- 后勤回归发现SET-CI是bAN状态的最强预测因素;其他同情心和alexithymia措施显示没有显著的群体差异.
结论:
- 一般领域的推断困难,特别是在因果推理方面,可能与男性兄弟姐妹对神经性厌食症的家族脆弱性有关.
- 这些发现突出了特定认知特征在AN风险的更广泛背景下潜在的作用.
- 需要进一步的研究,以告知早期识别和干预策略的个人在家族风险的AN.
