A formal modeling approach was used to characterize decision-making processes in bipolar disorder. Decision making was examined in 28 bipolar patients (14 acute and 14 remitted) and 25 controls using the Iowa Gambling Task (Bechara et al., 1994), a decision-making task used for assessing cognitive impulsivity. To disentangle motivational and cognitive aspects of decision-making processes, we applied a formal cognitive model to the performance on the Iowa Gambling Task. The model has three parameters: The relative impact of rewards and punishments on evaluations, the impact of recent and past payoffs, and the degree of choice consistency. The results indicated that acute bipolar patients were characterized by low choice consistency, or a tendency to make erratic choices. Low choice consistency improved the prediction of acute bipolar disorder beyond that provided by cognitive functioning and self-report measures of personality and temperament.

使用正式建模方法来表征双相情感障碍的决策过程。使用Iowa赌博任务 (Bechara等,1994) 在28位双相情感障碍患者 (14位急性和14位缓解) 和25位对照中检查了决策,这是一种用于评估认知冲动的决策任务。为了消除决策过程的动机和认知方面,我们将正式的认知模型应用于爱荷华州赌博任务的表现。该模型具有三个参数: 奖励和惩罚对评估的相对影响,近期和过去收益的影响以及选择的一致性程度。结果表明,急性双相情感障碍患者的选择一致性低,或倾向于做出不稳定的选择。低选择一致性改善了急性双相情感障碍的预测,超出了认知功能和自我报告的人格和气质测量所提供的预测。
