Across various structured diagnostic instruments, the criteria used to diagnose alcohol use disorder (AUD) are not assessed consistently. For example, different instruments often pose questions that reflect different thresholds of the underlying symptoms. We consider the criteria for and to demonstrate the influence of using different thresholds for a positive symptom endorsement with respect to the estimated edges of a symptom network. Results indicate that the utilization of these differing thresholds leads to significant differences in edge weights. Generally, higher thresholds relate more strongly to lower prevalence rate criteria, and the reverse for lower thresholds. These findings have implications for reproducibility of effects in symptom networks and their generalization across studies.
在各种结构化诊断工具中,用于诊断酒精使用障碍(AUD)的标准评估并不一致。例如,不同的工具经常提出反映潜在症状不同阈值的问题。我们考虑[具体内容缺失]的标准,以说明在症状网络的估计边缘方面使用不同的阳性症状认可阈值的影响。结果表明,这些不同阈值的使用导致边缘权重存在显著差异。一般来说,较高的阈值与较低的患病率标准关联更强,而较低的阈值则相反。这些发现对症状网络中效应的可重复性及其在不同研究中的推广具有启示意义。
