International Classification of Diseases, 11th revision (ICD-11) adjustment disorder (AjD) is characterized by two main symptom clusters: preoccupation with the stressor and failure to adapt to the stressor. The network analytic approach provides important information on the structural validity of a disorder and reveals which symptoms are most prominent. To date, no study compared the network structure of AjD symptoms in clinical and nonclinical samples, which could potentially inform our understanding of psychopathological mechanisms that underlie AjD and identify core targets for therapy.
A network analysis was conducted on AjD symptoms as assessed by the Adjustment Disorder-New Module (ADNM-8) using data from 330 clinical participants from the UK and a nonclinical sample of 699 participants from Switzerland.
Comparisons of network structure invariance revealed differences between the network structure of the clinical and the nonclinical samples. Results highlight that in terms of both edges strength and centrality, failure to adapt symptoms was more prominent in the clinical sample, while the preoccupation symptoms were more prominent in the nonclinical sample. Importantly, global strength was similar across networks.
Results provide evidence of the coherence of AjD in the ICD-11 as assessed by the ADNM questionnaire. They tentatively suggest that subclinical AjD may be characterized by emerging preoccupation symptoms that may result in failure to adapt and functional impairment in clinical manifestation of AjD. However, there is a need for replication and longitudinal research to further validate this hypothesis.
国际疾病分类第 11 版（ICD-11）调整障碍（AjD）的特征是两个主要的症状群：对压力源的关注和无法适应压力源。网络分析方法提供了关于疾病结构有效性的重要信息，并揭示了哪些症状最为突出。迄今为止，尚无研究比较临床和非临床样本中 AjD 症状的网络结构，这可能有助于我们了解 AjD 背后的心理病理机制，并确定治疗的核心目标。
使用来自英国的 330 名临床参与者和来自瑞士的 699 名非临床参与者的 ADNM-8 数据，对 AjD 症状进行网络分析。
网络结构不变性的比较显示了临床样本和非临床样本网络结构之间的差异。结果突出表明，在适应不良症状的边缘强度和中心性方面，临床样本更为突出，而在非临床样本中，关注症状更为突出。重要的是，网络之间的整体强度相似。
结果提供了 ADNM 问卷评估的 ICD-11 中 AjD 一致性的证据。他们初步表明，亚临床 AjD 可能以出现的关注症状为特征，这些症状可能导致 AjD 的临床表现中适应不良和功能障碍。然而，需要进行复制和纵向研究来进一步验证这一假设。
