Defeat and entrapment have been highlighted in the development of suicidal ideation within the Integrated Motivational-Volitional model of suicidal behavior. Research suggests that entrapment has to be differentiated into internal and external entrapment. The aim of this study was to investigate the associations between defeat, internal, external entrapment, and suicidal ideation within and prospectively over measurements.
A sample of 308 psychiatric inpatients (53% female) aged 18 to 81 years (M = 36.92, SD = 14.30) was assessed for the four constructs after admission to a psychiatric ward and six, nine, and twelve months later. Multilevel analyses were conducted to examine associations.
Defeat was associated with (a change in) internal and external entrapment. Defeat predicted a change in internal entrapment over time. Defeat and internal, but not external, entrapment were associated with (a change in) suicidal ideation. Internal entrapment was able to predict suicidal ideation. Internal entrapment and defeat predicted a change in suicidal ideation over time.
Results highlight the importance to distinguish between internal and external entrapment, and their specific association with suicidal ideation. Perceptions of internal entrapment are of central relevance when experiencing suicidal ideation and should be considered in clinical practice.
在自杀行为的综合动机-意愿模型中，失败和困境已被强调为自杀意念发展的因素。研究表明，困境必须分为内部困境和外部困境。本研究的目的是调查在测量内和前瞻性测量中，失败、内部困境、外部困境与自杀意念之间的关联。
对 308 名年龄在 18 至 81 岁之间（M=36.92，SD=14.30）的精神病住院患者（53%为女性）进行评估，在入院后以及六个月、九个月和十二个月后评估这四个结构。采用多层次分析来检验关联。
失败与（变化的）内部困境和外部困境有关。失败预测了随时间的变化内部困境。失败和内部困境，但不是外部困境，与（变化的）自杀意念有关。内部困境能够预测自杀意念。内部困境和失败预测了自杀意念随时间的变化。
结果强调了区分内部困境和外部困境及其与自杀意念的特定关联的重要性。当经历自杀意念时，对内部困境的认知至关重要，在临床实践中应予以考虑。
