This study aims to evaluate the process of decision-making in patients with obsessive-compulsive disorder (OCD) using the Iowa Gambling Task (IGT). In addition, we intend to expand the understanding of clinical and demographic characteristics that influence decision-making.
Our sample consisted of 214 subjects (107 diagnosed with OCD and 107 healthy controls) who were evaluated on their clinical, demographic and neuropsychological features. Moreover, the Iowa Gambling Task (IGT), a task that detects and measures decision-making impairments, was used.
We found that OCD patients performed significantly worse on the IGT. Furthermore, features such as symptoms of anxiety did not influence IGT performance.
Impaired decision-making seems to be a key feature of OCD. Given that OCD is a complex heterogeneous disorder, homogeneous groups are necessary for an accurate characterization of our findings.
本研究旨在使用爱荷华赌博任务（IGT）评估强迫症（OCD）患者的决策过程。此外，我们打算加深对影响决策的临床和人口统计学特征的理解。
我们的样本包括214名受试者（107名被诊断为强迫症患者和107名健康对照），对他们的临床、人口统计学和神经心理学特征进行了评估。此外，还使用了爱荷华赌博任务（IGT），这是一项检测和测量决策障碍的任务。
我们发现强迫症患者在IGT上的表现明显更差。此外，焦虑症状等特征并不影响IGT表现。
决策受损似乎是强迫症的一个关键特征。鉴于强迫症是一种复杂的异质性疾病，为了准确描述我们的研究结果，有必要进行同质分组。
