Abstract

We used multitrait-multimethod (MTMM) modeling to examine general factors of psychopathology in three samples of youths (Ns = 2,119, 303, and 592) for whom three informants reported on the youth’s psychopathology (e.g., child, parent, teacher). Empirical support for the p-factor diminished in multi-informant models compared with mono-informant models: The correlation between externalizing and internalizing factors decreased, and the general factor in bifactor models essentially reflected externalizing. Widely used MTMM-informed approaches for modeling multi-informant data cannot distinguish between competing interpretations of the patterns of effects we observed, including that the p factor reflects, in part, evaluative consistency bias or that psychopathology manifests differently across contexts (e.g., home vs. school). Ultimately, support for the p factor may be stronger in mono-informant designs, although it does not entirely vanish in multi-informant models. Instead, the general factor of psychopathology in any given mono-informant model likely reflects a complex mix of variances, some substantive and some methodological.

We thank Christopher Hopwood and two other reviewers for their feedback on this article. Data used in the preparation of this article were obtained from the Adolescent Brain Cognitive Development (ABCD) Study ( https://abcdstudy.org ), which is held in the National Institute of Mental Health Data Archive, and from a limited-access data set provided by the Child Mind Institute Biobank, Healthy Brain Network ( http://www.healthybrainnetwork.org ). The ABCD Study is a multisite, longitudinal study designed to recruit more than 10,000 children ages 9 to 10 and follow them more than 10 years into early adulthood. The ABCD Study is supported by the National Institutes of Health (NIH) and additional federal partners under National Institute on Drug Abuse Grants U01-DA041022, U01-DA041028, U01-DA041048, U01-DA041089, U01-DA041106, U01-DA041117, U01-DA041120, U01-DA041134, U01-DA041148, U01-DA041156, U01-DA041174, U24-DA041123, U24-DA041147, U01-DA041093, and U01-DA041025.
