Contemporary psychological theoretical models of suicide hypothesize that defeat and entrapment underlie the development of suicidal ideation. This hypothesis has never been tested in people who experience bipolar disorder. Regression analysis revealed that defeat and entrapment significantly predicted suicidal ideation at 4-month follow-up. The relationship between defeat and suicidal ideation was mediated by total entrapment and internal entrapment, but not external entrapment. Results suggest that perceived defeat and entrapment underlie the development of prospective suicidal ideation in bipolar disorder. Findings could potentially improve the assessment of suicide risk in people who experience bipolar disorder.
当代自杀的心理学理论模型假设，挫败感和被困感是自杀意念发展的基础。这一假设从未在经历双相情感障碍的人群中得到过验证。回归分析显示，在 4 个月的随访中，挫败感和被困感显著预测了自杀意念。挫败感与自杀意念之间的关系是由总被困感和内在被困感介导的，但不是由外在被困感介导的。研究结果表明，在双相情感障碍中，感知到的挫败感和被困感是前瞻性自杀意念发展的基础。这些发现可能会提高对经历双相情感障碍的人群的自杀风险评估。
