One strategy for improving the clinical utility of mental health diagnostic systems is to better align them with how clinicians conceptualize psychopathology in practice. This approach was used in International Classification of Diseases 11th Revision (ICD-11) development, but its underlying assumption-a link between taxonomic "fit" and clinical utility-remains untested.
Using data from global mental health clinician samples (combined N = 5404), we investigated the association between taxonomic fit and clinical utility in mental disorder categories.
The overall association between fit and utility was positive (r = 0.19) but statistically not different from zero (95% confidence interval [CI]: -0.06, 0.43) in this small sample (N = 39 ICD/DSM categories). However, a positive association became clear after correcting for outliers (r = 0.34 [0.05, 0.58] or higher). Further insights were apparent for specific diagnoses given their locations in the scatterplot.
Results suggest a positive link between taxonomic fit and clinical utility in mental disorder diagnoses, highlighting future research directions.
提高心理健康诊断系统临床实用性的一种策略是使其与临床医生在实践中对精神病理学的概念化更好地保持一致。这一方法被用于国际疾病分类第 11 版（ICD-11）的制定，但它背后的假设——分类“契合度”与临床实用性之间的联系——仍未经检验。
我们利用来自全球心理健康临床医生样本（合并 N=5404）的数据，研究了精神障碍类别中分类契合度和临床实用性之间的关联。
在这个小样本（N=39 个 ICD/DSM 类别）中，整体上契合度与实用性之间存在正相关（r=0.19），但在统计学上与零无差异（95%置信区间：-0.06，0.43）。然而，在纠正离群值后，这种正相关变得明显（r=0.34 [0.05，0.58]或更高）。从散点图中特定诊断的位置可以明显看出，具体诊断的结果更为清晰。
结果表明，精神障碍诊断中分类契合度与临床实用性之间存在正相关，这突出了未来的研究方向。
