Empirical support for a dual process model of the p-factor: Interaction effects between preschool executive control and preschool negative emotionality on general psychopathology.
Journal of Psychopathology and Clinical Science, Vol 131(8), Nov 2022, 817-829; doi:10.1037/abn0000777Recent work indicates that a general factor, often referred to as the p-factor, underlies nearly all forms of psychopathology. Although the criterion validity and utility of this general factor have been well supported, questions remain about the substantive meaning of the p-factor. The purpose of the present longitudinal study was to empirically test the hypothesis that the p-factor reflects dysregulation arising from a combination of high dispositional negative emotionality and low executive control. The current study ex...

A clinical PREMISE for personalized models: Toward a formal integration of case formulations and statistical networks.
Journal of Psychopathology and Clinical Science, Vol 131(8), Nov 2022, 906-916; doi:10.1037/abn0000779Over the past decade, the idiographic approach has received significant attention in clinical psychology, incentivizing the development of novel approaches to estimate statistical models, such as personalized networks. Although the notion of such networks aligns well with the way clinicians think and reason, there are currently several barriers to implementation that limit their clinical utility. To address these issues, we introduce the Prior Elicitation Module for Idiographic System Estimation (PREMISE), a novel approach...

Gamma-band entrainment abnormalities in schizophrenia: Modality-specific or cortex-wide impairment?
Journal of Psychopathology and Clinical Science, Vol 131(8), Nov 2022, 895-905; doi:10.1037/abn0000778A growing body of literature suggests that cognitive impairment in people with schizophrenia (PSZ) results from disrupted cortical excitatory/inhibitory (E-I) balance, which may be linked to gamma entrainment and can be measured noninvasively using electroencephalography (EEG). However, it is not yet known the degree to which these entrainment abnormalities covary within subjects across sensory modalities. Furthermore, the degree to which cross-modal gamma entrainment reflects variation in biological processes associated w...

A critical period for pandemic adaptation: The evolution of depressive symptomatology in a representative sample of adults across a 17-month period during COVID-19.
Journal of Psychopathology and Clinical Science, Vol 131(8), Nov 2022, 881-894; doi:10.1037/abn0000786This 17-month longitudinal study on a representative sample of 4,361 Norwegian adults employs an observational ABAB design across 6 repeated assessments and 3 pandemic waves to systematically investigate the evolution of depressive symptomatology across all modifications of social distancing protocols (SDPs) from their onset to termination. Using Latent Change Score Models to analyze 26,166 observations, the study empirically corroborates that critical fluctuations in depressive symptomatology within and across individuals...

Fluctuations in and associations between physical and psychological distance to suicide methods, fearlessness about death, and suicidal intent.
Journal of Psychopathology and Clinical Science, Vol 131(8), Nov 2022, 868-880; doi:10.1037/abn0000783Previous evidence has highlighted the potential roles of both physical and psychological distance to suicide methods as an important factor in conferring suicide risk; however, less is known about the temporal stability of and associations between these constructs, other facets of capability for suicide, and suicide-related outcomes. The present study examined fluctuations in and associations between physical and psychological distance to suicide methods, fearlessness about death, and suicidal intent using ecological momen...

A broad internalizing dimension accounts for the genetic associations between personality and individual internalizing disorders.
Journal of Psychopathology and Clinical Science, Vol 131(8), Nov 2022, 857-867; doi:10.1037/abn0000782Much research has demonstrated that psychopathology can be described in terms of broad dimensions, representing liability for multiple psychiatric disorders. Broad spectra of psychopathology (e.g., internalizing and externalizing) are increasingly used as targets for research investigating the development, etiology, and course of psychopathology because they account for patterns of relatedness among disorders that were once presumed distinct. Thus, these spectra represent alluring targets due to their comprehensive and par...

Meta-analytic tests of measurement invariance of internalizing and externalizing psychopathology across common methodological characteristics.
In this study, we addressed this issue by testing whether and how methodological features affect the empirical structure of psychopathology using meta-analytic measurement invariance models of Internalizing and Externalizing across multiple sample characteristics. Published studies estimating factor analytic models from Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnoses were screened. A total of 47 samples (N = 118,966) were included in the meta-analysis. Data were pooled into meta-analytic correlation matrices using random effects models that accounted for sampling variability. Multigroup confirmatory f...

Genetic variance in conscientiousness relates to youth psychopathology beyond executive functions.
Journal of Psychopathology and Clinical Science, Vol 131(8), Nov 2022, 830-846; doi:10.1037/abn0000781Because deficits in self-regulation (SR) are core features of many diverse psychological disorders, SR may constitute one of many dimensions that underlie shared variance across diagnostic boundaries (e.g., the p factor, a dimension reflecting shared variance across multiple psychological disorders). SR definitions encompass constructs mapping onto different theoretical traditions and different measurement approaches, however. Two SR operationalizations, executive functioning and conscientiousness, are often used interchan...
