认知灵活性与青少年的整体神经过食症症状没有联系. 然而,降低认知灵活性预测了治疗结束时自我诱导的吐,这表明有针对性的干预措施的潜力.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 临床心理学 临床心理学
背景情况:
- 认知刚性在神经性厌食症中很常见,但在神经性饮食症 (BN) 中不太了解,特别是在青少年中.
- 在BN中认知灵活性 (CF) 评估对于理解和治疗这种疾病至关重要.
研究的目的:
- 为了比较两个认知灵活性的测量方法,威斯康星州卡片排序任务 (WCST) 和Trail Making Task (TMT),与青少年的BN症状有关.
- 探索CF的临床相关性,并为青少年BN提供最佳评估实践信息.
主要方法:
- 分析了78名被诊断为BN的青少年的数据.
- 利用线性回归和障碍回归来评估WCST坚持性错误和TMT表现对BN症状 (饮食障碍检查全球得分,暴饮暴食,自我诱导吐发作 (SVEs)) 在基线和治疗结束 (EOT) 的影响.
主要成果:
- 在CF测量和基线BN症状之间没有发现显著的关联.
- TMT的表现预测了在EOT时SVE的可能性增加.
- 在那些在EOT有SVE的人群中,WCST的坚持性错误与更高的SVE频率相关.
结论:
- 与神经性厌食症相比,认知刚性可能对青少年BN不那么重要.
