요약The Hierarchical Taxonomy of Psychopathology (HiTOP) is a quantitative diagnostic system that is gaining traction as a framework for studying the correlates of mental health problems. However, it remains unknown how best to operationalize hierarchically related psychopathology dimensions during criterion validity tests. In a series of simulations, I evaluated the performance of latent variable (i.e., structural equation modeling; SEM) and factor score representations of hierarchical psychopathology constructs in criterion validity analyses. In models based on continuously distributed psychopathology indicators (e.g., symptom composites), SEM and factor score estimate methods both tended to yield unbiased estimates of criterion validity coefficients. In contrast, for models based on dichotomous indicators (e.g., categorical diagnoses), SEM led to more accurate estimates than factor scores in most cases. Across both types of input data, I observed elevated false positive rates in the factor score estimate approaches, relative to SEM. Coverage was also more favorable in SEM, irrespective of input data type. Power and precision results were essentially equivalent across analytic method. Model misspecification (e.g., fitting a higher-order model to data generated from a bifactor population model) exerted no systematic bias on parameter estimates. I offer recommendations for psychopathology researchers based on these results and provide an R function (https://osf.io/u3j5d/) that investigators can use to apply the approaches studied here in real-world datasets.
