Psychiatric inpatients are at heightened risk for suicide, and evidence suggests that psychiatric inpatients with bipolar mood disorders may be at greater risk for suicide ideation compared to those with non-bipolar mood disorders. There is a paucity of research directly comparing risk factors for suicide ideation in bipolar versus non-bipolar mood disorders in an inpatient sample. The current study sought to clarify the association between two constructs from the interpersonal theory of suicide (i.e., perceived burdensomeness and thwarted belongingness) in leading to suicide ideation among psychiatric inpatients with bipolar and non-bipolar mood disorders. Participants were (N=90) psychiatric inpatients with a bipolar (n = 20) or non-bipolar mood disorder (n=70; per their medical charts). Perceived burdensomeness, but not thwarted belongingness, was significantly associated with suicide ideation after adjusting for other covariates. This suggests perceived burdensomeness may play a key role in suicide ideation among psychiatric inpatients with any mood disorder and highlights the importance of assessment and intervention of perceived burdensomeness in this population. Contrary to our hypothesis, mood disorder group (i.e., bipolar versus non-bipolar) did not moderate the relations between perceived burdensomeness/thwarted belongingness and suicide ideation.
精神科住院患者自杀风险较高，有证据表明，与非双相情感障碍患者相比，双相情感障碍患者的自杀意念风险可能更高。在住院患者样本中，直接比较双相情感障碍与非双相情感障碍患者自杀意念风险因素的研究很少。本研究旨在阐明人际理论自杀（即感知负担和归属感受挫）的两个结构之间的关联，这些关联会导致双相和非双相情感障碍的精神科住院患者产生自杀意念。参与者为（N=90）精神科住院患者，其中双相（n=20）或非双相情感障碍（n=70；根据其病历记录）。在调整其他协变量后，感知负担与自杀意念显著相关，但归属感受挫则不然。这表明感知负担可能在任何情绪障碍的精神科住院患者的自杀意念中起着关键作用，并强调了在该人群中评估和干预感知负担的重要性。与我们的假设相反，情绪障碍组（即双相情感障碍与非双相情感障碍）并没有调节感知负担/归属感受挫与自杀意念之间的关系。
