“Terminal anorexia nervosa” may not be terminal: An empirical evaluation.
This study’s purpose was to empirically examine a subgroup of participants with AN who met the first three criteria of T-AN—and a smaller subset who also met a proxy index of the fourth criterion involving death (TD-AN)—and compare them to an adult “not terminal” anorexia nervosa (NT-AN) group and to a “not terminal” subset 30 years of age or older (NTO-AN). Patients at U.S. eating disorder treatment facilities (N = 782; T-AN: n = 51, TD-AN: n = 16, NT-AN: n = 731, NTO-AN: n = 133), all of whom met criteria for a current Diagnostic and Statistical Manual of Mental Disorders, 5th Edition diagnosis of AN, were ...

Higher risk—less data: A systematic review and meta-analysis on the role of sex and gender in trauma research.
Journal of Psychopathology and Clinical Science, Vol 133(3), Apr 2024, 257-272; doi:10.1037/abn0000899Women and men are at different risk for posttraumatic stress disorder (PTSD). It is unclear, however, how studies on PTSD risk factors integrate this knowledge into their research. Moreover, the temporal development of women’s higher PTSD risk is unknown. In this systematic review and meta-analysis, we examine how prospective studies on PTSD development (k = 47) consider sex and gender across four domains (samples, terminology, analyses, and reporting). Further, we differentially analyze sex/gender differences within fiv...

Heightened neural reward responsiveness functions as a plasticity factor moderating the association between childhood emotional abuse and young adult depressive symptoms: Evidence of differential susceptibility.
Journal of Psychopathology and Clinical Science, Vol 133(3), Apr 2024, 245-256; doi:10.1037/abn0000911As a neural indicator of reward responsiveness (RR), reward positivity (RewP) has been demonstrated to moderate the association between stress exposure and depressive symptoms. However, extant research has primarily (a) focused on life stress rather than early maltreatment, (b) ignored the time-frequency components, and (c) has been based on a traditional perspective of diathesis stress. The present study aimed to comprehensively examine whether and how neurophysiological (RewP and its time–frequency decomposition compon...

The hierarchical taxonomy of psychopathology in clinical high risk for psychosis: Validation and extension.
Journal of Psychopathology and Clinical Science, Vol 133(3), Apr 2024, 235-244; doi:10.1037/abn0000893The Hierarchical Taxonomy of Psychopathology (HiTOP) consortium’s transdiagnostic dimensional model of psychopathology has considerable support; however, this model has been underresearched in individuals at clinical high risk for psychosis (CHR-P), a population that may advance the model. CHR-P individuals not only have attenuated psychotic symptoms that vary in severity, but also have many comorbid diagnoses and varied clinical outcomes, including disorders with uncertain relations to HiTOP (e.g., obsessive-compulsive ...

Comparing the interactions of risk factors by method of suicide among veterans: A moderated network analysis approach.
Journal of Psychopathology and Clinical Science, Vol 133(3), Apr 2024, 273-284; doi:10.1037/abn0000895Despite the well-established link between firearm access and suicide, less is known about other variables that may influence the risk for death by self-inflicted gunshot versus other methods of suicide. As individual factors have demonstrated limited predictive ability, scholars have called for studies that consider the multifaceted relations between myriad variables. One alternative to the typical cause-and-effect approach for investigating various forms of psychopathology is network analysis. However, few studies have ap...

Testing whether the relations between sex and psychopathology are accounted for by structural morphometry in ABCD.
Journal of Psychopathology and Clinical Science, Vol 133(3), Apr 2024, 223-234; doi:10.1037/abn0000892Sex differences in psychopathology are well-established, with females demonstrating higher rates of internalizing (INT) psychopathology and males demonstrating higher rates of externalizing (EXT) psychopathology. Using two waves of data from the Adolescent Brain Cognitive Development Study (N = 6,778 at each wave), the current study tested whether the relations between sex and psychopathology might be accounted for by structural brain differences. In general, we found robust, relatively consistent relations between sex and...

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...
