Suicidal ideation (SI) is a known precursor to suicide among men. While loneliness and thwarted belongingness (TB) have been identified as key factors influencing SI, no study has reported on all three constructs to investigate whether loneliness is associated with SI by way of TB. Furthermore, it is not clear whether personality impairment has a moderating role on this process. The present study examined the impact of loneliness on SI among men and whether TB mediated this relationship. Additionally, the study investigated whether personality impairment (i.e., self-functioning, interpersonal functioning) moderated the relationship between loneliness and TB. Canadian men (N = 434) completed an online survey that included self-report assessments of the study constructs. Conditional process modeling was used to test the indirect effect of loneliness on SI via the mediating effect of TB. Findings indicated a significant association between loneliness and SI that was mediated by TB. Further, impairment in self-functioning moderated the relationship between loneliness and TB, indicating that the relationship was stronger among men with greater difficulties in self-functioning. The findings are important to consider within the COVID-19 context, as they point to the need to reduce the detrimental impacts of loneliness, thereby potentially mitigating male SI.
自杀意念 (SI) 是男性自杀的已知前兆。虽然孤独感和归属感受挫 (TB) 已被确定为影响 SI 的关键因素，但没有研究报告这三个结构来调查孤独感是否通过 TB 与 SI 相关。此外，尚不清楚人格障碍是否对这一过程有调节作用。本研究考察了孤独感对男性 SI 的影响，以及 TB 是否在这种关系中起中介作用。此外，该研究还调查了人格障碍（即自我功能、人际关系功能）是否调节了孤独感和 TB 之间的关系。加拿大男性（N=434）完成了一项在线调查，其中包括对研究结构的自我报告评估。条件过程建模用于测试通过 TB 的中介效应，检验孤独感对 SI 的间接影响。研究结果表明，孤独感与 SI 之间存在显著关联，TB 在其中起中介作用。进一步的，自我功能障碍调节了孤独感和 TB 之间的关系，这表明在自我功能障碍较大的男性中，这种关系更强。这些发现对于在 COVID-19 背景下需要考虑，因为它们指出需要减少孤独感的不利影响，从而可能减轻男性 SI。
