There is disagreement regarding the role of perceived control in obsessive-compulsive disorder (OCD). The present study used a traditional illusion of control paradigm (Alloy and Abramson, 1979) to empirically test control estimation in OCD. Twenty-six OCD patients and 26 matched comparison subjects completed an illusion of control task wherein their goal was to attempt to exert control over a light bulb. The density of reinforcement (high, low) and the valence of trials (gain, loss) were experimentally manipulated within subjects. Unbeknownst to participants, the illumination of the light bulb was predetermined and irrespective of their behavior. OCD patients exhibited lower estimates of control compared with healthy comparison subjects. There were no interactions between group and outcome density or group and valence. We found that OCD patients endorse lower estimates of control than comparison subjects. This finding highlights a potential role for contingency learning in the disorder.
对于在强迫症（OCD）中感知控制的作用存在分歧。本研究使用了传统的控制错觉范式（Alloy 和 Abramson，1979）来实证检验 OCD 中的控制估计。26 名 OCD 患者和 26 名匹配的对照组被试完成了一项控制错觉任务，他们的目标是试图控制一个灯泡。强化密度（高、低）和试验效价（收益、损失）在被试内进行了实验操纵。参与者并不知道，灯泡的照明是预先确定的，与他们的行为无关。与健康对照组相比，OCD 患者的控制估计值较低。组与结果密度或组与效价之间没有交互作用。我们发现，与对照组相比，OCD 患者的控制估计值较低。这一发现突出了在该障碍中，连续学习可能起作用。
