感官门控量表（SGI）是一个36项的测量，用于评估个人的主观能力，以调节，过滤，过度包括，区分，注意到，并容忍感官刺激。由于其与感觉处理缺陷的理论和经验联系，该测量已被广泛用于精神病和其他精神病理学的研究。目前的工作填补了需要在该领域内的一个简短的措施，感觉门控畸变，保持原来的措施的效用。为此，从2个独立的研究中心招募了大量样本（总计n = 1552），分别用于项目减少/选择和简要测量验证。这些样本反映了精神病谱系障碍、精神病谱系障碍高危人群、非精神病对照人群和非精神病精神病对照人群的亚组。因子分析和项目反应模型被用来创建SGI-简报（SGI-B; 10个Likert评分项目），一个一维的自我报告措施，保留了原来的SGI的跨诊断（即，目前跨疾病）的效用和内容广度。研究结果表明，SGI-B具有良好的心理测量特性（α = 0.92），并通过与精神病学测量的强关联证明了外部效度，理论上与人格（例如，知觉失调）相关的测量，以及与实验室为基础的感觉处理任务在听觉和视觉领域与原始版本相当的适度关联。因此，SGI-B将成为临床科学研究中感觉门控异常的维度和跨诊断检查的有价值的工具，同时减少管理员和参与者的负担。
The Sensory Gating Inventory (SGI) is a 36-item measure used to assess an individual’s subjective ability to modulate, filter, over-include, discriminate, attend to, and tolerate sensory stimuli. Due to its theoretical and empirical link with sensory processing deficits, this measure has been used extensively in studies of psychosis and other psychopathology. The current work fills a need within the field for a briefer measure of sensory gating aberrations that maintains the original measure’s utility. For this purpose, large samples (total n = 1552) were recruited from 2 independent sites for item reduction/selection and brief measure validation, respectively. These samples reflected subgroups of individuals with a psychosis-spectrum disorder, at high risk for a psychosis-spectrum disorder, nonpsychiatric controls, and nonpsychosis psychiatric controls. Factor analyses and item-response models were used to create the SGI-Brief (SGI-B; 10 Likert-rated items), a unidimensional self-report measure that retains the original SGI’s transdiagnostic (ie, present across disorders) utility and content breadth. Findings show that the SGI-B has excellent psychometric properties (alpha = 0.92) and demonstrates external validity through strong associations with measures of psychotic symptomatology, theoretically linked measures of personality (eg, perceptual dysregulation), and modest associations with laboratory-based sensory processing tasks in the auditory and visual domains on par with the original version. Accordingly, the SGI-B will be a valuable tool for dimensional and transdiagnostic examination of sensory gating abnormalities within clinical science research, while reducing administrator and participant burden.
