Suicidal behavior constitutes a multi-cause phenomenon that may also be present in people without a mental disorder. This study aims to analyze suicidal behavior outcomes in a sample of attempters, from a symptom-based approach.
The sample comprised 673 patients (72% female; = 40.9 years) who attended a hospital emergency department due to a suicide attempt. A wide range of clinical factors (e.g., psychopathology symptoms, psychiatric diagnoses, impulsivity, acquired capability), was administered within 15 days after the index attempt. Nine psychopathology domains were explored to identify the profile of symptoms, using latent profile analysis. The relationship between the profile membership and suicide outcome (i.e., intensity of suicidal ideation, number of suicide behaviors, and medical injury derived from index attempt) was also studied, using linear and logistic regression.
Three psychopathology profiles were identified: high-symptom profile (45.02% of participants), moderate-symptom profile (42.50%), and low-symptom profile (12.48%). High-symptom profile members were more likely to show higher risk of non-suicidal self-injury, acquired capability for suicide, and more severe suicide behavior and ideation. On the other hand, a more severe physical injury was associated with low-symptom profile membership in comparison to membership from the other profiles ( < 0.45, < .05).
A symptom-based approach may be useful to monitor patients and determine the risk of attempt repetition in the future and potential medical injury, and to optimize prevention and intervention strategies.
自杀行为是一种多因现象,也可能存在于没有精神障碍的人群中。本研究旨在从基于症状的角度分析尝试自杀者的自杀行为结果。
该样本包括 673 名因自杀企图而到医院急诊室就诊的患者(72%为女性;平均年龄 40.9 岁)。在指数尝试后 15 天内,评估了广泛的临床因素(例如,精神病理学症状、精神诊断、冲动、习得能力)。使用潜在剖面分析探讨了九个精神病理学领域,以确定症状特征。研究了特征成员与自杀结果(即自杀意念的强度、自杀行为的数量以及指数尝试导致的医疗伤害)之间的关系,使用线性和逻辑回归。
确定了三个精神病理学特征:高症状特征(45.02%的参与者)、中症状特征(42.50%)和低症状特征(12.48%)。高症状特征成员更有可能表现出自残、习得自杀能力和更严重的自杀行为和意念的高风险。另一方面,与其他特征相比,低症状特征成员与更严重的身体伤害相关(<0.45,<0.05)。
基于症状的方法可能有助于监测患者,确定未来重复尝试和潜在医疗伤害的风险,并优化预防和干预策略。
