The Nature of Internalizing Psychopathology
Considerable structural research has supported the hypothesis that psychopathology is hierarchically organized with a general 'p' factor at the apex (although some research has raised doubts about this factor) with three broad spectra at the next level: Internalizing, Externalizing, and Psychosis. In this symposium, we explore the nature of Internalizing. Chris Conway will first discuss conditions and populations in which an Internalizing dimension may be difficult to extract or may show an atypical data pattern, cautioning us to be thoughtful, not glib, in positing highly abstract constructs such as internalizing. David Watson will then present results on the development of an omnibus measure of Internalizing psychopathology by the Hierarchical Taxonomy of Psychopathology (HiTOP) consortium, highlighting subcomponents that are—and are not—strong and replicable markers of the dimension. Using the HiTOP framework, Susan South examined longitudinal associations of Internalizing with marital satisfaction, and will present data regarding which subcomponents have the strongest associations and which are related less strongly with marital satisfaction. Lee Anna Clark will close by exploring the boundary of the construct, presenting data demonstrating that Internalizing encompasses not only psychopathological symptoms, but also maladaptive-range personality traits and a broad range of psychosocial functioning.
