Abstract

Introduction: Suicidal ideation variability refers to within-day fluctuations in suicidal ideation, and has recently been proposed as an indicator of suicide risk. However, not much is known yet about its correlates and clinical relevance.

Methods: We examined characteristics of real-time suicidal ideation using Ecological Momentary Assessment in 82 individuals with current active suicidal ideation. Data were collected four times daily over 21 days. Latent profile analysis was used to identify subtypes of suicidal ideation. We further examined sociodemographic and clinical correlates of the profiles, and their association with the occurrence of suicide attempts during a 1-year follow-up.

Results: We identified three "digital" phenotypes of suicidal ideation that differed on the frequency, intensity and variability of ideation. The profiles were: high frequency, high intensity, moderate variability (Phenotype 1), moderate/high frequency, moderate intensity, high variability (Phenotype 2), and moderate frequency, low intensity, low variability (Phenotype 3). Phenotypes 1 and 2 were associated with a worse clinical profile at baseline (higher suicidal ideation and depressive symptom severity), and increased odds of suicide attempt during follow-up, compared to Phenotype 3. Phenotype 1 was further characterized by repeated suicidal behavior.

Conclusions: Two phenotypes of real-time suicidal ideation were identified that appear to confer a higher risk of suicidal behavior in the near future (12 months). These phenotypes were characterized by higher variability of suicidal ideation-and also higher intensity and frequency of ideation. Considering the small sample size, the clinical usefulness of the profiles remains to be demonstrated.

实时自杀意念的数字表型:相关因素和后果。
简介自杀意念变异性是指自杀意念在一天之内的波动,最近被提出作为自杀风险的一个指标。然而,人们对其相关性和临床意义还知之甚少:方法:我们使用生态学瞬间评估对 82 名当前有主动自杀意念的人的实时自杀意念特征进行了研究。数据收集为期 21 天,每天四次。我们使用潜伏特征分析来确定自杀意念的亚型。我们进一步研究了这些特征的社会人口学和临床相关性,以及它们与一年随访期间自杀未遂发生率的关联:结果:我们发现了自杀意念的三种 "数字 "表型,它们在自杀意念的频率、强度和可变性方面各不相同。它们分别是:高频率、高强度、中等变异性(表型 1),中等/高频率、中等强度、高变异性(表型 2),以及中等频率、低强度、低变异性(表型 3)。与表型 3 相比,表型 1 和表型 2 的基线临床特征更差(自杀意念和抑郁症状严重程度更高),随访期间自杀未遂的几率更高。表型 1 的另一个特点是反复出现自杀行为:结论:研究发现了两种实时自杀意念表型,它们似乎会在不久的将来(12 个月)带来更高的自杀行为风险。这些表型的特点是自杀意念的变异性更高,意念的强度和频率也更高。考虑到样本量较小,这些特征的临床实用性还有待证实。

期刊介绍: Acta Psychiatrica Scandinavica acts as an international forum for the dissemination of information advancing the science and practice of psychiatry. In particular we focus on communicating frontline research to clinical psychiatrists and psychiatric researchers. Acta Psychiatrica Scandinavica has traditionally been and remains a journal focusing predominantly on clinical psychiatry, but translational psychiatry is a topic of growing importance to our readers. Therefore, the journal welcomes submission of manuscripts based on both clinical- and more translational (e.g. preclinical and epidemiological) research. When preparing manuscripts based on translational studies for submission to Acta Psychiatrica Scandinavica, the authors should place emphasis on the clinical significance of the research question and the findings. Manuscripts based solely on preclinical research (e.g. animal models) are normally not considered for publication in the Journal.
