A growing body of literature supports the potential existence of a new clinical entity, Acute suicidal affective disturbance (ASAD), which is characterized by rapid-onset, acute suicidality. This study aimed to evaluate whether current ASAD symptoms (i.e., suicidal intent, thwarted belongingness, perceived burdensomeness, disgust with others and oneself, agitation, irritability, insomnia, and nightmares) comprise a psychopathological network distinct from anxiety and depression symptoms.
A sample of 167 psychiatric inpatients completed self-report measures of current ASAD, anxiety, and depression symptoms.
Network analyses revealed three distinct clusters of symptoms corresponding to ASAD, anxiety, and depression symptom self-report measure items. Namely, ASAD symptoms not only demonstrated strong associations with each other, but they also exhibited weak associations with symptoms of anxiety and depression.
This study utilized a cross-sectional design and distinct self-report measures to assess all constructs, which may have led to methodological confounds that influenced the observed network structure.
Overall, our findings provide further evidence for ASAD as a syndrome with strongly interrelated symptoms. Furthermore, results indicate that ASAD may represent a construct distinct from anxiety and depression, underscoring its potential diagnostic value. Additional research is needed to replicate these findings across other high-risk populations, as well as to examine how ASAD symptoms may relate to other psychiatric symptoms.
越来越多的文献支持一种新的临床实体——急性自杀情感障碍（ASAD）的存在，其特征是快速发作、急性自杀。本研究旨在评估当前的 ASAD 症状（即自杀意念、归属感受挫、自我负担感、对他人和自己的厌恶、激动、易怒、失眠和噩梦）是否构成一个与焦虑和抑郁症状不同的精神病理网络。
167 名精神病住院患者完成了当前 ASAD、焦虑和抑郁症状的自我报告测量。
网络分析显示，有三个不同的症状集群与 ASAD、焦虑和抑郁症状的自我报告测量项目相对应。即，ASAD 症状不仅彼此之间表现出强烈的关联，而且与焦虑和抑郁症状之间也表现出较弱的关联。
本研究采用了横断面设计和不同的自我报告测量方法来评估所有的结构，这可能导致了影响观察到的网络结构的方法学混淆。
总的来说，我们的发现进一步证明了 ASAD 是一种具有强烈相互关联症状的综合征。此外，结果表明 ASAD 可能代表一种与焦虑和抑郁不同的结构，突出了其潜在的诊断价值。需要进行更多的研究，以在其他高风险人群中复制这些发现，并研究 ASAD 症状如何与其他精神症状相关。
