Within the integrated motivational-volitional model of suicidal behavior, entrapment that consecutively leads to hopelessness is considered as a proximal risk factor for suicidal ideation. Entrapment can refer to both external and internal circumstances whereby results of recent studies indicate that internal entrapment plays a more important role than external entrapment in the development of suicidal ideation. It has been considered that to escape internal entrapment might be more complicated than to change external circumstances. However, it remains unclear whether the greater effect of internal entrapment on suicidal ideation is due to greater feelings of hopelessness. Therefore, the aim of this study was to address this research gap and to examine the effects of internal and external entrapment on hopelessness and suicidal ideation.
N = 454 participants from a community sample (75% female) aged between 18 and 73 years (M = 29.91, SD = 11.56) conducted a cross-sectional online survey. All participants were assessed for suicidal ideation, hopelessness, and internal as well as external entrapment. Pearson product-moment correlations and two mediation analyses were conducted.
All constructs were significantly correlated. For both internal and external entrapment, an effect on suicidal ideation was found. Both effects were partially mediated by hopelessness, this mediation was larger for external entrapment. The completely standardized indirect effect used to compare the mediation models was larger for external entrapment than for internal entrapment.
Hopelessness mediated the association between external entrapment as well as internal entrapment and suicidal ideation. This effect was larger for external entrapment.
在自杀行为的综合动机-意志模型中,连续导致绝望的困境被认为是自杀意念的近端风险因素。困境既可以指外部环境,也可以指内部环境,最近的研究结果表明,内部困境在自杀意念的发展中比外部困境发挥更重要的作用。人们认为,摆脱内部困境可能比改变外部环境更复杂。然而,内部困境对自杀意念的影响更大是否是因为更强烈的绝望感,这一点仍不清楚。因此,本研究旨在填补这一研究空白,并检验内部和外部困境对绝望感和自杀意念的影响。
来自社区样本的 454 名参与者(女性占 75%)年龄在 18 至 73 岁之间(M = 29.91,SD = 11.56),进行了一项横断面在线调查。所有参与者都接受了自杀意念、绝望感以及内部和外部困境的评估。进行了 Pearson 积差相关分析和两项中介分析。
所有结构均呈显著相关。内部和外部困境都对自杀意念产生了影响。这两种影响都部分通过绝望感产生,外部困境的中介作用更大。为了比较中介模型,使用完全标准化间接效应,发现外部困境的中介作用大于内部困境。
绝望感中介了外部困境和内部困境与自杀意念之间的关联。外部困境的这种中介作用更大。
