Depressive symptoms as a heterogeneous and constantly evolving dynamical system: Idiographic depressive symptom networks of rapid symptom changes among persons with major depressive disorder.
Journal of Psychopathology and Clinical Science, Vol 133(2), Feb 2024, 155-166; doi:10.1037/abn0000884Major depressive disorder (MDD) is conceptualized by individual symptoms occurring most of the day for at least two weeks. Despite this operationalization, MDD is highly variable with persons showing greater variation within and across days. Moreover, MDD is highly heterogeneous, varying considerably across people in both function and form. Recent efforts have examined MDD heterogeneity byinvestigating how symptoms influence one another over time across individuals in a system; however, these efforts have assumed that symp...

Are there reciprocal interplays among Chinese adolescents’, fathers’, and mothers’ depression at the within-family level? A family systems perspective.
Journal of Psychopathology and Clinical Science, Vol 133(2), Feb 2024, 140-154; doi:10.1037/abn0000883Controversy surrounds the reciprocity between adolescent and parental depression. Limited studies rigorously tested the transactional model of depression from a family systems perspective considering the involvement of all family members, particularly in non-Western nations, using advanced modeling approaches that disentangle between- and within-unit (i.e., family) variances (e.g., random intercept cross-lagged panel model [RI-CLPM]). This population-based multi-informant longitudinal study applied RI-CLPM to evaluate the ...

Longitudinal dynamics between anxiety and depression in bipolar spectrum disorders.
Journal of Psychopathology and Clinical Science, Vol 133(2), Feb 2024, 129-139; doi:10.1037/abn0000890Anxiety and depression are common among individuals with bipolar spectrum disorders (BSDs), with anxiety being a risk factor for depression and vice versa. While the harmful effects of these symptoms are well recognized, their temporal dynamics have not been fully tested. To address this gap, our study investigated bidirectional relationships between anxiety and depression in individuals with BSDs using data from the Prechter Longitudinal Study of Bipolar Disorder, collected over an average of 11 years. We included 651 par...

Limited psychological and social effects of lifetime cannabis use frequency: Evidence from a 30-year community study of 4,078 twins.
Conclusions: The cotwin control results suggest that more frequent cannabis use causes small increases in cannabis use disorder symptoms, approximately 1.3 symptoms when going from a once-a-year use to daily use. For other outcomes, our results are more consistent with familial confounding, at least in this community population of twins.

Are central eating disorder network symptoms sensitive to item selection and sample? Implications for conceptualization of eating disorder psychopathology from a network perspective.
Journal of Psychopathology and Clinical Science, Vol 133(1), Jan 2024, 48-60; doi:10.1037/abn0000865Item selection is a critical decision in modeling psychological networks. The current preregistered two-study research used random selections of 1,000 symptom networks to examine which eating disorder (ED) and co-occurring symptoms are most central in longitudinal networks among individuals with EDs (N = 71, total observations = 6,060) and tested whether centrality changed based on which items were included in the network. Participants completed 2 weeks of ecological momentary assessment (five surveys/day). In Study 1, we ob...

Sociodemographic reporting and sample composition over 3 decades of psychopathology research: A systematic review and quantitative synthesis.
Journal of Psychopathology and Clinical Science, Vol 133(1), Jan 2024, 20-36; doi:10.1037/abn0000871Although researchers seek to understand psychological phenomena in a population, quantitative research studies are conducted in smaller samples meant to represent the larger population of interest. This systematic review and quantitative synthesis considers reporting of sociodemographic characteristics and sample composition in the Journal of Abnormal Psychology (now the Journal of Psychopathology and Clinical Science) over the past 3 decades. Across k = 1,244 empirical studies, there were high and increasing rates of report...

Principles and procedures for revising the hierarchical taxonomy of psychopathology.
Journal of Psychopathology and Clinical Science, Vol 133(1), Jan 2024, 4-19; doi:10.1037/abn0000886Quantitative, empirical approaches to establishing the structure of psychopathology hold promise to improve on traditional psychiatric classification systems. The Hierarchical Taxonomy of Psychopathology (HiTOP) is a framework that summarizes the substantial and growing body of quantitative evidence on the structure of psychopathology. To achieve its aims, HiTOP must incorporate emerging research in a systematic, ongoing fashion. In this article, we describe the historical context and grounding of the principles and procedure...

Inaugural editorial.
Journal of Psychopathology and Clinical Science, Vol 133(1), Jan 2024, 1-3; doi:10.1037/abn0000889In this inaugural editorial, the author discusses his editorial priorities for the Journal of Psychopathology and Clinical Science (JCPS), as well as transparency and openness as they relate to the journal. In sum, the author believes psychopathology is amid a major paradigm shift. Some of the associated changes are quite visible, as they relate to moving away from traditional diagnostic nosologies toward more scientifically tractable models. However, to be successful in the next era we need to develop models that are transdia...

Posttraumatic symptoms and poor sleep are independent pathways to agency disruptions and dissociation: A longitudinal study with objective sleep assessment.
Journal of Psychopathology and Clinical Science, Vol 133(2), Feb 2024, 192-207; doi:10.1037/abn0000885Dissociation and diminished sense of agency are experiential distortions of disintegration in the perception of self and action. Although one is often implied in the other, they are seldom studied together. Assessing their relationship and shared influences may allow for a more comprehensive and nuanced understanding of dissociative experiences. We aimed to examine their temporal (concurrent or directional) co-occurrence, and to elucidate their etiology, focusing on posttraumatic symptoms (PTS), poor sleep, and their hypot...

Prospective examination of mechanisms linking minority stress and anxious/depressed affect at the event level: The roles of emotion regulation strategies and proximal minority stressors.
Conclusions: Results provided support for the roles of rumination and expressive suppression as mechanisms of linking minority stress and anxious/depressed affect. The concurrent evidence for other mechanisms suggests that future research with more temporal resolution is necessary to determine the temporality and directionality of these associations.

The affective benefits of real-world exploration during the COVID-19 pandemic.
Journal of Psychopathology and Clinical Science, Vol 133(2), Feb 2024, 167-177; doi:10.1037/abn0000888Increasing daily exploration is linked to improvements in affective well-being. However, COVID-19 elevated uncertainty when leaving the home, altering the risk-reward of balance of geospatial novelty. To this end, we simultaneously collected real-world geospatial tracking and experience sampling of emotion, prior to and during the first year of the pandemic in 630 individuals. COVID-19 reduced exploration and subjective well-being. Yet, despite the health risks of exploring during the pandemic, the days of highest affectiv...

Neurocognitive risk phenotyping to predict mood symptoms in adolescence.
This study used machine learning to test whether neurocognitive variables predicted future manic or anhedonic symptoms in two adolescent samples risk-enriched for lifetime mood disorders (Sample 1, n = 73, ages = 13–25, M [SD] = 19.22 [2.49] years, 68% lifetime mood disorder) or familial mood disorders (Sample 2, n = 154, ages = 13–21, M [SD] = 16.46 [1.95] years, 62% first-degree family history of mood disorder). Participants completed cognitive testing and functional magnetic resonance imaging at baseline, for behavioral and neural measures of reward processing and executive functioning. Next, participants completed ...

Acute dissociation as part of the defense cascade: Associations with behavioral, autonomic, and experiential threat responses in posttraumatic stress disorder.
Journal of Psychopathology and Clinical Science, Vol 133(1), Jan 2024, 76-89; doi:10.1037/abn0000873Dissociative symptoms, such as depersonalization and derealization, are experienced by about half of individuals with posttraumatic stress disorder (PTSD). Theoretical models propose that acute dissociation is accompanied by specific behavioral, physiological, and experiential alterations and contributes to unfavorable PTSD symptom course. Yet, empirical evidence is scarce. Here, we explored associations between dissociative and behavioral, physiological, and experiential threat responses as well as effects of dissociative r...

Do emotion regulation difficulties in depression extend to social context? Everyday interpersonal emotion regulation in current and remitted major depressive disorder.
Journal of Psychopathology and Clinical Science, Vol 133(1), Jan 2024, 61-75; doi:10.1037/abn0000877Individuals with major depressive disorder (MDD) have difficulties regulating emotion on their own. As people also use social resources to regulate emotion (i.e., interpersonal emotion regulation [IER]), we examined whether these difficulties extend to IER in current and remitted MDD compared to those with no psychiatric disorders (i.e., controls). Adults with current MDD (n = 48), remitted MDD (n = 80), and controls (n = 87) assessed via diagnostic interviewing completed 2-week experience sampling, reporting on how frequent...
