The picture of suicide in obsessive-compulsive disorder (OCD) is unclear because previous research did not uniformly control for depressive symptoms when examining the relationship between OCD and suicidality. Specific links between OC symptom dimensions and suicidality were also not adequately studied. As such, we investigated specific associations between OC symptom dimensions and suicidality, beyond the contribution of depressive symptoms, in an OCD analog sample of college students, a group traditionally at risk for suicide. One hundred and forty-six college students (103 females; 43 males) who exceeded the clinical cut-off for OC symptoms on the Obsessive-Compulsive Inventory, Revised (OCI-R) were recruited. Participants completed an online questionnaire containing measures that assessed suicidality and OC and depressive symptom severity. Total OC symptom severity, unacceptable thoughts, and especially violent obsessions exhibited significant positive zero-order correlations with suicidality. However, analyses of part correlations indicated that only violent obsessions had a significant unique association with suicidality after controlling for depressive symptoms. Our findings support the hypothesis that violent obsessions have a specific role in suicidality beyond the influence of depressive symptoms in an OCD analog sample of college students. A strong clinical focus on suicide risk assessment and safety planning in college students reporting violent obsessions is therefore warranted. Future related research should employ longitudinal or prospective designs and control for other possible comorbid symptoms in larger and more representative samples of participants formally diagnosed with OCD in order to verify the generalizability of our findings to these groups.
强迫症(OCD)中的自杀情况尚不明朗,因为先前的研究在考察强迫症与自杀倾向之间的关系时,并未对抑郁症状进行统一控制。强迫症症状维度与自杀倾向之间的具体联系也未得到充分研究。因此,我们在一个传统上有自杀风险的大学生强迫症模拟样本中,研究了强迫症症状维度与自杀倾向之间的具体关联,排除了抑郁症状的影响。招募了146名大学生(103名女性;43名男性),他们在修订版强迫症量表(OCI-R)上的强迫症症状超过了临床临界值。参与者完成了一份在线问卷,其中包含评估自杀倾向以及强迫症和抑郁症状严重程度的量表。强迫症症状总严重程度、不可接受的想法,尤其是暴力强迫观念与自杀倾向呈现出显著的正零阶相关性。然而,偏相关性分析表明,在控制了抑郁症状后,只有暴力强迫观念与自杀倾向存在显著的独特关联。我们的研究结果支持这样一种假设,即在大学生强迫症模拟样本中,暴力强迫观念在自杀倾向中具有特定作用,超出了抑郁症状的影响。因此,对于报告有暴力强迫观念的大学生,临床应高度关注自杀风险评估和安全规划。未来的相关研究应采用纵向或前瞻性设计,并在正式诊断为强迫症的更大且更具代表性的参与者样本中控制其他可能的共病症状,以验证我们的研究结果对这些群体的普遍性。
