Hybrid models of psychopathology propose to combine the current categorical diagnostic system with shared symptom dimensions common across various disorders. Recently, the first empirically derived hybrid model of social anxiety was developed, including both a specific factor for the diagnostic category of social anxiety and 5 nonspecific factors for related symptoms. The present investigation developed a self-report measure-the Multidimensional Assessment of Social Anxiety (MASA)-based on this model to further the research on hybrid models.
This investigation included three studies across large undergraduate (N = 411; 52.3% male; mean [M] age = 19.6) and clinical (N = 684; 61.4% female; M age = 35.8) samples, involving the administration of the MASA item pool and existing measures of related constructs.
Through a series of psychometric evaluations, the initial 466-item pool was reduced to a final 38-item measure that represented 6 distinct scales with adequate model fit, internal consistency, test-retest reliability, and convergent and discriminant validity.
Together, these studies likely will lead to additional research and advances in the development of the hybrid models of the mood and anxiety disorders through the dissemination and administration of the MASA.
精神病理学的混合模型建议将当前的分类诊断系统与各种障碍共有的共同症状维度相结合。最近，开发了第一个经验主义衍生的社交焦虑混合模型，包括社交焦虑诊断类别的特定因素和 5 个与相关症状相关的非特定因素。本研究基于该模型开发了一种自我报告测量工具——多维社交焦虑评估（MASA），以进一步研究混合模型。
本研究包括三项研究，涉及大型本科生样本（N=411；52.3%为男性；平均年龄 [M] = 19.6）和临床样本（N=684；61.4%为女性；M 年龄 = 35.8），包括 MASA 项目池和现有相关结构测量的管理。
通过一系列心理测量评估，最初的 466 项项目池被减少到最终的 38 项测量，代表 6 个不同的具有足够模型拟合度、内部一致性、测试-重测可靠性以及收敛和区别有效性的量表。
总的来说，这些研究可能会通过 MASA 的传播和管理，促进混合模型在心境和焦虑障碍领域的进一步研究和发展。
