The aim of this study was to investigate the relationship between the levels of insight and checking-related uncertainty in patients with obsessive-compulsive disorder (OCD).
Twenty OCD patients with checking compulsions and without current comorbidity were recruited. We used an experimental paradigm that gave subjects the opportunity to check during a decision-making task, thereby allowing for the calculation of a response time index (RTI) as the 'uncertainty cost' during decision-making. The level of insight was assessed with the Brown Assessment of Beliefs Scale (BABS).
Regression analyses indicated a significant positive correlation between RTI and BABS scores (r = 0.49).
The level of insight is related to cognitive characteristics underlying OCD symptoms, in particular, checking-related uncertainty in checking OCD patients.
The absence of a comparison group and the low number of included patients are the main limitations of the present study.
本研究旨在探讨强迫症（OCD）患者的洞察力水平与检查相关不确定性之间的关系。
招募了 20 名有检查强迫但无当前合并症的 OCD 患者。我们使用了一种实验范式，让受试者在决策任务中进行检查，从而可以计算出反应时间指数（RTI）作为决策过程中的“不确定性成本”。洞察力水平用布朗信念量表（BABS）进行评估。
回归分析表明，RTI 与 BABS 评分之间存在显著正相关（r=0.49）。
洞察力水平与 OCD 症状的认知特征有关，特别是在检查强迫症患者中，与检查相关的不确定性有关。
本研究的主要局限性是缺乏对照组和纳入患者数量较少。
