Although obsessive-compulsive disorder (OCD) features maladaptive decision making, previous research examining economic decision making in OCD has yielded inconsistent results. Here we examined whether unmedicated adults with OCD ( = 268) differ from healthy controls (HC; = 256) on two measures of decision making about potential rewards: 1) delay discounting, the tendency to prefer rewards sooner rather than later, even if the delayed reward is larger, and 2) risk tolerance, the willingness to gamble for uncertain rewards when the risk is known. Data were collected in Brazil, India, the Netherlands, South Africa, and the USA as part of the Global OCD study. After controlling for age, sex, education, socioeconomic status, IQ, and site, individuals with OCD did not differ from HC in either delay discounting or risk tolerance. However, patients with OCD who reported more anxiety and depression showed higher delay discounting, or a relative preference for immediate rewards.
尽管强迫症（OCD）具有适应不良的决策特点，但先前研究强迫症患者经济决策的结果并不一致。在此，我们研究了268名未接受药物治疗的成年强迫症患者与256名健康对照者（HC）在关于潜在奖励的两种决策测量上是否存在差异：1）延迟折扣，即即使延迟奖励更大，也倾向于更快获得奖励而非更晚获得奖励的趋势；2）风险承受能力，即在已知风险的情况下为不确定奖励进行赌博的意愿。作为全球强迫症研究的一部分，数据在巴西、印度、荷兰、南非和美国收集。在控制了年龄、性别、教育程度、社会经济地位、智商和研究地点后，强迫症患者在延迟折扣或风险承受能力方面与健康对照者没有差异。然而，报告有更多焦虑和抑郁的强迫症患者表现出更高的延迟折扣，即相对更偏好即时奖励。
