A recent integrative cognitive model proposed that multiple, extreme, personalized, positive and negative appraisals of internal states predispose to maintain and exacerbate bipolar symptoms. This study aimed to directly assess conviction in a range of positive and negative appraisals of internal states suggested by the model, by using a laboratory-based computerized task. In a student sample (n = 68), a history of hypomania was associated with more positive and less negative appraisals of internal states, and a history of depression was associated with more negative appraisals and less positive appraisals of internal states. The sample was then split into three groups for comparison: bipolar risk (n = 18), depression risk (n = 20) and controls (n = 30). Relative to controls, the bipolar risk group made more extreme ratings of catastrophic appraisals of low activation states and tended to make more extreme ratings of appraisals of high activation states. The depression risk group scored higher on a range of negative appraisals of low activation states. These findings provide tentative support for the role of both positive and negative, extreme, personalized appraisals of internal states in hypomania and depression.
最近提出的一个综合认知模型认为，对内部状态的多种、极端、个性化、积极和消极的评价会导致双相症状的维持和恶化。本研究旨在通过使用基于实验室的计算机化任务，直接评估该模型所提出的一系列内部状态的积极和消极评价的信念程度。在学生样本（n = 68）中，轻躁狂史与对内部状态的更多积极评价和更少消极评价相关，而抑郁史与对内部状态的更多消极评价和更少积极评价相关。然后，该样本被分为三组进行比较：双相风险组（n = 18）、抑郁风险组（n = 20）和对照组（n = 30）。与对照组相比，双相风险组对低激活状态的灾难性评价做出了更极端的评价，并且对高激活状态的评价往往更极端。抑郁风险组在一系列低激活状态的消极评价中得分更高。这些发现为内部状态的积极和消极、极端、个性化评价在轻躁狂和抑郁中的作用提供了初步支持。
