Emerging evidence suggests a potential association between “leaky gut syndrome” and low-grade systemic inflammation in individuals with psychiatric disorders, such as schizophrenia. Gut dysbiosis could increase intestinal permeability, allowing the passage of toxins and bacteria into the systemic circulation, subsequently triggering immune-reactive responses. This study delves into understanding the relationship between plasma markers of intestinal permeability and symptom severity in schizophrenia. Furthermore, the influence of lifestyle habits on these intestinal permeability markers was determined.
Methods
Biomarkers of intestinal permeability, namely lipopolysaccharide-binding protein (LBP), lipopolysaccharides (LPS), and intestinal fatty acid binding protein (I-FABP), were analyzed in 242 adult schizophrenia patients enrolled in an observational, cross-sectional, multicenter study from four centers in Spain (PI17/00246). Sociodemographic and clinical data were collected, including psychoactive drug use, lifestyle habits, the Positive and Negative Syndrome Scale to evaluate schizophrenia symptom severity, and the Screen for Cognitive Impairment in Psychiatry to assess cognitive performance.
Results
Results revealed elevated levels of LBP and LPS in a significant proportion of patients with schizophrenia (62% and 25.6%, respectively). However, no statistically significant correlation was observed between these biomarkers and the overall clinical severity of psychotic symptoms or cognitive performance, once confounding variables were controlled for. Interestingly, adherence to a Mediterranean diet was negatively correlated with I-FABP levels (beta = −0.186, t = −2.325, p = 0.021), suggesting a potential positive influence on intestinal barrier function.
Conclusions
These findings underscore the importance of addressing dietary habits and promoting a healthy lifestyle in individuals with schizophrenia, with potential implications for both physical and psychopathological aspects of the disorder.
Preschool anxiety is highly prevalent and well known to predict risk for future psychopathology. The present study explores whether a diagnosis of an anxiety disorder in preschool interacts with (a) social skills and (b) cognitive ability to longitudinally predict psychopathology, two well-known protective factors, among a sample of 207 children measured at preschool (Mage = 4.34 years) and early childhood (Mage = 6.61 years). To assess social skills and cognitive ability, we utilized the Social Skills Rating Scale and the Differential Abilities Scale, respectively. To assess psychopathology, we utilized the parent report of the Preschool Age Psychiatric Assessment. Hierarchical linear regression models revealed significant interactions between both social skills and cognitive ability with preschool anxiety. We observed that social skills protected against emergent psychopathology for both children with and without anxiety, although this association was stronger for children with preschool anxiety. Contrastingly, cognitive ability served as a protective factor against future psychopathology primarily among children without preschool anxiety. Results from this study identify targets for future intervention and inform our understanding of how preschool anxiety, a common disorder among young children, shapes future psychopathology risk in childhood.
Unpredictability is a core but understudied dimension of adversities and has been receiving increasing attention recently. The effects of unpredictability on psychopathology and the underlying neural mechanisms, however, remain unclear. It is also unknown how unpredictability interacts with other dimensions of adversities in predicting brain development and psychopathology of youth.
Methods
We applied cluster robust standard errors to examine how unpredictability was associated with the developmental changes in resting-state functional connectivity (rsFC) of large-scale brain networks implicated in psychopathology, as well as the moderating role of deprivation, using data from the Adolescent Brain Cognitive Development (ABCD) study, which included four measurements from baseline (mean ± s.d. age, 119.13 ± 7.51 months; 2815 females) to 3-year follow-up (N = 5885).
Results
After controlling for threat, unpredictability was associated with a smaller increase in rsFC within default mode network (DMN) and a smaller decrease in rsFC between cingulo-opercular network (CON) and DMN. Neighborhood educational deprivation moderated the associations between unpredictability and changes in rsFC within DMN and fronto-parietal network (FPN), as well as between CON and DMN. A smaller decrease in rsFC between CON and DMN mediated the association between unpredictability and externalizing problems. Neighborhood educational deprivation moderated the indirect pathway from unpredictability to externalizing problems via a smaller decrease in CON-DMN rsFC.
Conclusions
Our findings shed light on the neural mechanisms underlying the associations between unpredictability and adolescents' psychopathology and the moderating role of deprivation, highlighting the significance of providing stable environment and abundant educational opportunities to facilitate optimal development.
The Emotion Regulation Questionnaire-Short Form (ERQ-S) is a brief 6-item self-report measure of two emotion regulation strategies, cognitive reappraisal and expressive suppression. It is a short form of the most widely used emotion regulation measure in the field, but currently there are limited data on the performance of the ERQ-S. The aim of this study was to introduce a Polish version of the ERQ-S, examine its psychometric properties and provide Polish norms to aid score interpretation. Our sample was 574 Polish-speaking adults aged 18–69 from the general community in Poland. We examined the ERQ-S’s factor structure and measurement invariance with confirmatory factor analysis. We assessed the concurrent validity of the questionnaire via relationships with psychopathology symptoms and well-being. As expected, the Polish version of the ERQ-S demonstrated strong factorial validity with a theoretically congruent 2-factor structure (cognitive reappraisal and expressive suppression factors), which was invariant across gender, age and education categories. The ERQ-S’s concurrent validity and internal consistency reliability were good. As expected, cognitive reappraisal was significantly associated with lower psychopathology symptoms and higher well-being, whereas the opposite pattern was present for expressive suppression. Overall, the Polish version of the ERQ-S has strong psychometric properties and good clinical relevance.
Research suggests that most mental health conditions have their onset in the critically social period of adolescence. Yet, we lack understanding of the potential social processes underlying early psychopathological development. We propose a conceptual model where daily-life social interactions and social skills form an intermediate link between known risk and protective factors (adverse childhood experiences, bullying, social support, maladaptive parenting) and psychopathology in adolescents – that is explored using cross-sectional data.
Methods
N = 1913 Flemish adolescent participants (Mean age = 13.8; 63% girls) were assessed as part of the SIGMA study, a large-scale, accelerated longitudinal study of adolescent mental health and development. Self-report questionnaires (on risk/protective factors, social skills, and psychopathology) were completed during class time; daily-life social interactions were measured during a subsequent six-day experience-sampling period.
Results
Registered uncorrected multilevel linear regression results revealed significant associations between all risk/protective factors and psychopathology, between all risk/protective factors and social processes, and between all social processes and psychopathology. Social processes (social skills, quantity/quality of daily social interactions) were uniquely predicted by each risk/protective factor and were uniquely associated with both general and specific types of psychopathology. For older participants, some relationships between social processes and psychopathology were stronger.
Conclusions
Unique associations between risk/protective factors and psychopathology signify the distinct relevance of these factors for youth mental health, whereas the broad associations with social processes support these processes as broad correlates. Results align with the idea of a social pathway toward early psychopathology, although follow-up longitudinal research is required to verify any mediation effect.
Decades of evidence have elucidated associations between early adversity and risk for negative outcomes. However, traditional conceptualizations of the biologic embedding of adversity ignore neuroscientific principles which emphasize developmental plasticity. Dimensional models suggest that separate dimensions of experiences shape behavioral development differentially. We hypothesized that deprivation would be associated with higher psychopathology and lower academic achievement through executive function and effortful control, while threat would do so through observed, and parent reported emotional reactivity.
Methods:
In this longitudinal study of 206 mother–child dyads, we test these theories across the first 7 years of life. Threat was measured by the presence of domestic violence, and deprivation by the lack of cognitive stimulation within the parent–child interaction. We used path analyses to test associations between deprivation and threat with psychopathology and school outcomes through cognition and emotional reactivity.
Results:
We show that children who experienced more deprivation showed poor academic achievement through difficulties with executive function, while children who experienced more threat had higher levels of psychopathology through increased emotional reactivity.
Conclusion:
These observations are consistent with work in adolescence and reflect how unique adverse experiences have differential effects on children’s behavior and subsequently long-term outcomes.
The Hierarchical Taxonomy of Psychopathology (HiTOP) offers a promising framework to identify the neurobiological mechanisms of psychopathology. Many forms of psychopathology are characterized by dysfunctional emotional reactivity. The late positive potential (LPP) is an event-related potential component that provides an index of neurobiological emotional reactivity. Several categorical disorders have demonstrated a similar association with the emotion-modulated LPP. It is possible that higher-order dimensional representations of psychopathology might explain the comparable results. The present study examined the association between HiTOP-consistent pathological personality dimensions across multiple levels of the hierarchy and neurobiological emotional reactivity.
Methods
The sample included 215 18–35-year-old adults (86% female) who were oversampled for psychopathology. Participants completed the emotional interrupt task while electroencephalography was recorded to examine the LPP. Participants also completed the Comprehensive Assessment of Traits relevant to Personality Disorders to assess pathological personality.
Results
At the spectra level, higher negative emotionality was associated with a larger emotion-modulated LPP, while higher detachment was associated with a smaller emotion-modulated LPP. There were no associations between higher-order psychopathology levels and the emotion-modulated LPP. Compared to categorical diagnoses, spectra-level personality pathology dimensions significantly improved the prediction of the emotion-modulated LPP.
Conclusions
The present study indicates that HiTOP spectra levels of negative emotionality and detachment demonstrate unique associations with neurobiological emotional reactivity. The study highlights the utility of examining dimensional and hierarchical, rather than categorical, representations of psychopathology in the attempt to identify the neurobiological origins of psychopathology.
Children’s externalizing behaviors are associated with impairments across the lifespan. Developmental psychopathology theories propose transactional (bidirectional) associations between child externalizing behaviors and parenting during childhood and adolescence. Yet, these foundational relations in early childhood are not well-studied. Utilizing a large, mixed-sex sample, we examined the reciprocal nature of parenting and child externalizing behaviors across early childhood using robust repeated-measures models. Repeated measures data were drawn from a socioeconomically diverse, longitudinal pregnancy cohort of 1287 (64% Black, 31% White) mother-child dyads at four time points (ages one to six). Three variables were included in cross-lagged panel models: observed parenting quality, child externalizing symptoms, and a maternal risk composite. In covariate-adjusted models, higher parenting quality at Wave 1 predicted lower child externalizing symptoms at Wave 2. Higher externalizing symptoms at Wave 1 and Wave 2 predicted lower parenting quality at Wave 2 and Wave 3, respectively. Maternal risk and parenting quality were not significantly associated. Findings showed both parent-driven and child-driven effects across early childhood that did not vary by child sex. The transactional nature of the parent-child relationship begins in infancy, underscoring the importance of early screening and provision of supports for families to minimize and prevent the development of serious psychopathology.
Navigating the complex relationship between violence and psychosis can frequently be challenging. Psychiatrists may find assessing and managing the risk of violence in this context daunting. In their article on the topic, Anderson et al helpfully summarise the role that psychopathology can play in this process. However, although careful elucidation of an individual's experiences may assist in the nuanced formulation of their risk and could offer a specific focus for interventions, the approach has potential shortcomings in certain settings. For some phenomena the link with violence is unclear and it may be constellations of symptoms that are important. Causal pathways are not always linear and there may be important mediators linking psychopathological features to behavioural outcomes. In the resource-limited settings in which many contemporary health services operate, a detailed assessment of psychopathology may be hampered by time or other constraints. Alternative, more scalable solutions may therefore be needed in particular scenarios.
Early maladaptive schemas (EMS), dysfunctional patterns of thought and emotions originated during childhood, latent in most mental disorders, might play a role in the onset of alcohol use disorder (AUD), although their impact on prognosis remains unknown. Our aim is to determine the presence of EMS in patients with AUD and their role in the psychopathology and course of addiction (relapse and withdrawal time). The sample included 104 patients and 100 controls. The diagnosis of AUD was made according to the Diagnostic and Statistical Manual of Mental Disorders (DSM–5) criteria, EMS were determined with the Young Schema Questionnaire in its Spanish version (YSQ–S3) and psychopathology with Symptom Checklist–27 (SCL–27). AUD group showed significantly higher scores in emotional deprivation, confused attachment, emotional inhibition and failure schemas. In addition, vulnerability schema correlated (> 0.500) with all subscales of SCL–27. Whereas social isolation, insufficient self-control and grandiosity schemas correlated with a higher number of relapses. But it was the grandiosity and punishment schemas that correlated with shorter abstinence time. These findings suggest that EMS are overrepresented in the AUD population and some correlate with psychopathology and worse AUD outcomes.
Dr. Dante Cicchetti’s pioneering theory and research on developmental psychopathology have been fundamental to the proliferation of research on intergenerational transmission over the last 40 years. In part due to this foundation, much has been learned about continuities and discontinuities in child maltreatment, attachment, parenting, and psychopathology across generations. Looking towards the future, we propose that this field stands to benefit from a prospective, three-generation approach. Specifically, following established prospective, longitudinal cohorts of children over their transition to parenting the next generation will afford the opportunity to investigate the developmental origins of intergenerational transmission. This approach also can address key outstanding questions and methodological limitations in the extant literature related to the confounding of retrospective and prospective measures; examination of mediators and moderators; and investigation of the roles of biology, environment, and their interplay. After considering these advantages, we offer several considerations and recommendations for future research, many of which are broadly applicable to the study of two or more generations. We hope that this discussion will inspire the leveraging of existing prospective cohorts to carry forward Dr. Cicchetti’s remarkable contributions, with the ultimate aim to inform the development of preventions and interventions that disrupt deleterious intergenerational cycles.
Neurocognitive dysfunction is a transdiagnostic finding in psychopathology, but relationships among cognitive domains and general and specific psychopathology dimensions remain unclear. This study aimed to examine associations between cognition and psychopathology dimensions in a large youth cohort.
Method
The sample (N = 9350; age 8–21 years) was drawn from the Philadelphia Neurodevelopmental Cohort. Data from structured clinical interviews were modeled using bifactor confirmatory factor analysis (CFA), resulting in an overall psychopathology (‘p’) factor score and six orthogonal psychopathology dimensions: dysphoria/distress, obsessive-compulsive, behavioral/externalizing, attention-deficit/hyperactivity, phobias, and psychosis. Neurocognitive data were aggregated using correlated-traits CFA into five factors: executive functioning, memory, complex cognition, social cognition, and sensorimotor speed. We examined relationships among specific and general psychopathology dimensions and neurocognitive factors.
Results
The final model showed both overall and specific associations between cognitive functioning and psychopathology, with acceptable fit (CFI = 0.91; TLI = 0.90; RMSEA = 0.024; SRMR = 0.054). Overall psychopathology and most psychopathology dimensions were negatively associated with neurocognitive functioning (phobias [p < 0.0005], behavioral/externalizing [p < 0.0005], attention-deficit/hyperactivity [p < 0.0005], psychosis [p < 0.0005 to p < 0.05]), except for dysphoria/distress and obsessive-compulsive symptoms, which were positively associated with complex cognition (p < 0.05 and p < 0.01, respectively).
Conclusion
By modeling a broad range of cognitive and psychopathology domains in a large, diverse sample of youth, we found aspects of neurocognitive functioning shared across clinical phenotypes, as well as domain-specific patterns. Findings support transdiagnostic examination of cognitive performance to parse variability in the link between neurocognitive functioning and clinical phenotypes.

In his book General Psychopathology, first published in 1913, Jaspers presented a methodological framework for exploring the phenomenology of symptoms of psychiatric disorders as well as relating experimental psychology and nosology to phenomenology. This chapter briefly introduces the phenomenological approach to symptoms and how this has influenced symptom- as opposed to diagnostic criterion-based assessment instruments, such as those based on the diagnostic statistical manual. A transcultural and historical perspective is employed to identify relevant symptoms of mood disorders and their temporal course. Descriptions and definitions of classical symptoms are provided and extended based on modern evidence to include changes in self-imagery, moral emotions, self-blame-related action tendencies, as well as mood-congruent biases in the representation of the past and future. Lastly the contribution of psychopathology to future subsyndrome discovery, translational cognitive neuroscience, and network-based approaches to the psychopathology of mood disorders is discussed.
This study aimed to parse between-person heterogeneity in growth of impulsivity across childhood and adolescence among participants enrolled in five childhood preventive intervention trials targeting conduct problems. In addition, we aimed to test profile membership in relation to adult psychopathologies. Measurement items representing impulsive behavior across grades 2, 4, 5, 7, 8, and 10, and aggression, substance use, suicidal ideation/attempts, and anxiety/depression in adulthood were integrated from the five trials (N = 4,975). We applied latent class growth analysis to this sample, as well as samples separated into nonintervention (n = 2,492) and intervention (n = 2,483) participants. Across all samples, profiles were characterized by high, moderate, low, and low-increasing impulsive levels. Regarding adult outcomes, in all samples, the high, moderate, and low profiles endorsed greater levels of aggression compared to the low-increasing profile. There were nuanced differences across samples and profiles on suicidal ideation/attempts and anxiety/depression. Across samples, there were no significant differences between profiles on substance use. Overall, our study helps to inform understanding of the developmental course and prognosis of impulsivity, as well as adding to collaborative efforts linking data across multiple studies to better inform understanding of developmental processes.
Growing evidence supports the unique pathways by which threat and deprivation, two core dimensions of adversity, confer risk for youth psychopathology. However, the extent to which these dimensions differ in their direct associations with youth psychopathology remains unclear. The primary aim of this preregistered meta-analysis was to synthesize the associations between threat, deprivation, internalizing, externalizing, and trauma-specific psychopathology. Because threat is proposed to be directly linked with socioemotional development, we hypothesized that the magnitude of associations between threat and psychopathology would be larger than those with deprivation. We conducted a search for peer-reviewed articles in English using PubMed and PsycINFO databases through August 2022. Studies that assessed both threat and deprivation and used previously validated measures of youth psychopathology were included. One hundred and twenty-seven articles were included in the synthesis (N = 163,767). Results of our three-level meta-analyses indicated that adversity dimension significantly moderated the associations between adversity and psychopathology, such that the magnitude of effects for threat (r’s = .21–26) were consistently larger than those for deprivation (r’s = .16–.19). These differences were more pronounced when accounting for the threat-deprivation correlation. Additional significant moderators included emotional abuse and youth self-report of adversity. Findings are consistent with the Dimensional Model of Adversity and Psychopathology, with clinical, research, and policy implications.
Friendships are a potential factor that influence maltreated children’s risk for psychopathology. This systematic review examined (1) how friendships influence the association between child maltreatment and psychopathology and (2) developmental differences in how friendships influence this association. Four databases were searched. Inclusion criteria were primary study, quantitative, measures of maltreatment and friendship up to the age of 18 years, measures of psychopathology up to the age of 24 years, and a non-maltreated sample. Exclusion criteria were qualitative, reviews or meta-analyses, no distinction between maltreatment and other trauma, and no differentiation between friendships and other support. Risk of bias was assessed. Data were narratively synthesized. Two hundred thirty-five articles were retrieved for full review. Fourteen met inclusion criteria (N = 98,676 participants). Eleven of the fourteen studies found that some aspect of friendships influenced the association between maltreatment and psychopathology, with positive qualities generally decreasing risk and negative qualities increasing risk for psychopathology. However, peer support exacerbated maltreated children’s risk for psychopathology in two studies. Only three studies assessed friendship prior to adolescence, which precluded conclusions regarding developmental differences. Future research should consider developmental differences and use findings and validated measures from the peer relations literature to better understand how friendships influence maltreated youth’s vulnerability to psychopathology.
Since its launch in a 1984 Special Issue of Child Development, significant contributions and insights have followed that have expanded our understanding of psychopathology and normal human growth and development. Despite these efforts, there are persistent and under-analyzed skewed patterns of vulnerability across and within groups. The persistence of a motivated forgetfulness to acknowledge citizens’ uneven access to resources and supports, or as stated elsewhere, “inequality presence denial,” is, at minimum, a policy, social and health practice problem. This article will examine some of these issues from the standpoint of a universal human vulnerability perspective. It also investigates sources of resistance to acknowledging and responding to the scholarship production problem of uneven representations of basic human development research versus psychopathology preoccupations by race. Collectively, findings suggest interesting “patchwork” patterns of particular cultural repertoires as ordinary social and scholarly traditions.
Neuroscience research underscores the critical impact of adverse experiences on brain development. Yet, there is limited understanding of the specific pathways linking adverse experiences to accelerated or delayed brain development and their ultimate contributions to psychopathology. Here, we present new longitudinal data demonstrating that neurocognitive functioning during adolescence, as affected by adverse experiences, predicts psychopathology during young adulthood. The sample included 167 participants (52% male) assessed in adolescence and young adulthood. Adverse experiences were measured by early maltreatment experiences and low family socioeconomic status. Cognitive control was assessed by neural activation and behavioral performance during the Multi-Source Interference Task. Psychopathology was measured by self-reported internalizing and externalizing symptomatology. Results indicated that higher maltreatment predicted heightened frontoparietal activation during cognitive control, indicating delayed neurodevelopment, which, in turn predicted higher internalizing and externalizing symptomatology. Furthermore, higher maltreatment predicted a steeper decline in frontoparietal activation across adolescence, indicating neural plasticity in cognitive control-related brain development, which was associated with lower internalizing symptomatology. Our results elucidate the crucial role of neurocognitive development in the processes linking adverse experiences and psychopathology. Implications of the findings and directions for future research on the effects of adverse experiences on brain development are discussed.
Developmental psychopathology started as an intersection of fields and is now a field itself. As we contemplate the future of this field, we consider the ways in which a newer, interdisciplinary field – human developmental neuroscience – can inform, and be informed by, developmental psychopathology. To do so, we outline principles of developmental psychopathology and how they are and/or can be implemented in developmental neuroscience. In turn, we highlight how the collaboration between these fields can lead to richer models and more impactful translation. In doing so, we describe the ways in which models from developmental psychopathology can enrich developmental neuroscience and future directions for developmental psychopathology.
Dante Cicchetti has had a lasting impact on our understanding of the development of externalizing psychopathology through at least two seminal contributions, including establishment of the field of developmental psychopathology and assertion of the hypothesis that early physical abuse and neglect trigger a cascade of maladaptive outcomes across the life course. These ideas have guided a program of research on children’s deviant social information processing and defensive mindset as the psychological mechanisms through which early physical abuse leads to long-term psychopathology. Longitudinal studies following children from early life through mid-adulthood show that physical abuse in the first five years of life leads children to adopt a defensive mindset that, in turn, cascades into long-term outcomes of externalizing psychopathology, incarceration, and dysfunction. Cicchetti’s ideas have also guided the development of preventive interventions to interrupt this life course.
