Studying Development of Psychopathology Using Changing Measures to Account for Heterotypic Continuity

Year: 2025

Type: article

Abstract: Objective: Psychopathology shows changes in behavioral manifestation across development, that is, heterotypic continuity. However, research has paid little attention to how to account for heterotypic continuity when examining the development of psychopathology. This longitudinal study accounted for heterotypic continuity of multiple psychopathology dimensions by using developmental scaling to place multi-informant ratings of children's behavior problems onto the same scale to chart children's trajectories. Method: The study examined children's (N = 231) development of 3 psychopathology dimensions-externalizing, internalizing, and thought-disordered-using different measures across 7 timepoints from 3 to 7.5 years of age. Psychopathology dimensions were assessed by mother-, father-, and teacher/caregiver-report. We compared 3 assessment approaches: the common items, upward/downward extension, and construct-valid items approaches. We compared 2 scoring approaches: mean scoring and developmental scaling. Developmental scaling aims to place scores from age-differing measures onto the same scale. We compared their accuracy, for externalizing problems, in terms of criterion validity with respect to observations of compliance and attention to task. Results: = 0.03-0.17). Conclusion: Using (1) age-differing measures to account for heterotypic continuity and (2) developmental scaling to link scores from the different measures onto the same scale may enable studying development of psychopathology across the lifespan. Diversity & Inclusion Statement: We worked to ensure sex and gender balance in the recruitment of human participants. We worked to ensure race, ethnic, and/or other types of diversity in the recruitment of human participants. We worked to ensure that the study questionnaires were prepared in an inclusive way.
