The current study extended prior work on the Normative Male Alexithymia Scale (NMAS), a unidimensional measure of some men's limitations in expressing emotion that results from gender-based socialization informed by the masculine norm of restrictive emotionality (RE). Data ( = 505 men) were from Amazon Mechanical Turk participants. First, dimensionality was reassessed using exploratory factor analysis, which supported the unidimensional structure. Second, based on these results, three 6-item models of the NMAS-Brief Form (NMAS-BF) were developed, based on classical test theory (CTT), CTT optimized to avoid item redundancy, and item response theory (IRT). Third, the relative fits of these versions were assessed using confirmatory factor analysis on a separate part of the sample, finding that the IRT version was the best fitting model. Fourth, evidence for reliability for the NMAS-BF items (α = .80) and validity was found. Convergent evidence for validity was supported by a significant, moderate, positive correlation between the latent constructs of the NMAS-BF and Toronto Alexithymia Scale-20 (TAS-20), which measures clinical alexithymia. Concurrent evidence for validity of the latent factor of the NMAS-BF was assessed in a structural regression model which found that the NMAS-BF uniquely predicted RE scores when TAS-20 scores were included in the model. Finally, incremental evidence for validity was examined using hierarchical multiple regression, finding that NMAS-BF scores significantly predicted variance in RE scores above and beyond that predicted by TAS-20 scores. The results are discussed in relation to prior literature, future research directions, applications to counseling practice, and limitations.

本研究扩展了先前关于规范性男性述情障碍量表（NMAS）的研究，NMAS 是一种衡量某些男性表达情感能力局限性的单一维度量表，这种局限性源于基于限制情感的男性规范的性别社会化。数据（n=505 名男性）来自亚马逊土耳其机器人参与者。首先，使用探索性因素分析重新评估了维度，该分析支持了单一维度结构。其次，基于这些结果，基于经典测试理论（CTT）、为避免项目冗余而优化的 CTT 以及项目反应理论（IRT），开发了三种 6 项 NMAS-简短形式（NMAS-BF）的模型。第三，在样本的另一部分使用验证性因素分析评估了这些版本的相对拟合度，发现 IRT 版本是拟合度最好的模型。第四，发现 NMAS-BF 项目的可靠性（α=0.80）和有效性的证据。NMAS-BF 与多伦多述情障碍量表-20（TAS-20）之间存在显著的、中度的正相关，这支持了有效性的收敛证据，TAS-20 用于衡量临床述情障碍。NMAS-BF 潜在因素的同时有效性通过结构回归模型进行评估，发现当将 TAS-20 得分纳入模型时，NMAS-BF 可以独立预测 RE 得分。最后，使用分层多元回归检验了有效性的增量证据，发现 NMAS-BF 分数可以显著预测 RE 分数的方差，超过 TAS-20 分数的预测。讨论部分涉及到与先前文献的关系、未来的研究方向、咨询实践的应用以及局限性。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
