Entrapment is an emerging theoretical and empirical factor associated with suicide. The current study expanded our understanding of entrapment by examining the Entrapment Scale factor structure, demographic correlates, and association with suicidal thoughts and behaviors (STBs). Data from an online cross-national study of suicide were analyzed from two samples of young adults aged 18-34 (United Kingdom [U.K.] sample N = 418; United States [U.S.] N = 414). Primary findings included: (1) factor-analytic support for a two factor (i.e., internal and external) Entrapment Scale structure; (2) variation in external entrapment subscale factor loadings by sample; (3) significant demographic correlates of elevated entrapment of younger age, female gender, and U.S. sample; (4) significant convergent positive associations for both entrapment types with cognitive (e.g., perceived burdensomeness), mental health (e.g., anxiety), and STB correlates; and (5) significant, robust associations of internal entrapment and perceived burdensomeness with STBs in the U.K. sample. Implications are reviewed for suicide prevention theory, research and practice.
束缚是与自杀相关的一个新兴理论和实证因素。本研究通过考察束缚量表的结构、人口统计学相关性以及与自杀意念和行为（STB）的关系，扩展了对束缚的理解。这项在线跨国自杀研究的数据来自两个年龄在 18 至 34 岁的年轻人样本（英国样本 N=418；美国样本 N=414）。主要发现包括：（1）对束缚量表的两因素（即内部和外部）结构的因子分析支持；（2）外部束缚子量表因子负荷在样本间的变化；（3）年轻、女性和美国样本的年龄、性别等人口统计学特征与束缚的相关性；（4）两种束缚类型与认知（如感知负担）、心理健康（如焦虑）和 STB 相关性的显著正相关；（5）在英国样本中，内部束缚和感知负担与 STB 的显著、稳健关联。本文回顾了对自杀预防理论、研究和实践的启示。
