RESUMEN
Psychiatric disorders are associated with significant social and economic burdens, many of which are related to issues with current diagnosis and treatments. The coronavirus (COVID-19) pandemic is estimated to have increased the prevalence and burden of major depressive and anxiety disorders, indicating an urgent need to strengthen mental health systems globally. To date, current approaches adopted in drug discovery and development for psychiatric disorders have been relatively unsuccessful. Precision psychiatry aims to tailor healthcare more closely to the needs of individual patients and, when informed by neuroscience, can offer the opportunity to improve the accuracy of disease classification, treatment decisions, and prevention efforts. In this review, we highlight the growing global interest in precision psychiatry and the potential for the National Institute of Health-devised Research Domain Criteria (RDoC) to facilitate the implementation of transdiagnostic and improved treatment approaches. The need for current psychiatric nosology to evolve with recent scientific advancements and increase awareness in emerging investigators/clinicians of the value of this approach is essential. Finally, we examine current challenges and future opportunities of adopting the RDoC-associated translational and transdiagnostic approaches in clinical studies, acknowledging that the strength of RDoC is that they form a dynamic framework of guiding principles that is intended to evolve continuously with scientific developments into the future. A collaborative approach that recruits expertise from multiple disciplines, while also considering the patient perspective, is needed to pave the way for precision psychiatry that can improve the prognosis and quality of life of psychiatric patients.

BACKGROUND: The high incidence of potentially traumatic events (PTEs) in Indonesia warrants early identification of those with probable trauma-related disorders in order to tailor prevention and intervention for trauma-related symptoms. OBJECTIVES: This study aims to adapt and validate a novel brief transdiagnostic screener, the Global Psychotrauma Screen (GPS), in Indonesian undergraduate students. METHODS: An online survey was administered among Indonesian undergraduate students (N = 322). Exploratory factor analysis, reliability analyses, clinical validity analyses, and correlational analyses were performed to evaluate the construct validity, reliability, clinical validity, and convergent-divergent validity of the Indonesian GPS. Hierarchical multiple regression was conducted to assess the relationship between risk factors and trauma-related symptoms. The relationship between four categories of trauma-related symptom severity and social/work functioning was measured using Analysis of Covariance. RESULTS: Exploratory factor analysis yielded a single-factor solution. The Indonesian GPS demonstrated good internal consistency, test-retest correlation, and absolute agreement, indicating good reliability. The Indonesian GPS also had an acceptable area under the curve, sensitivity, and specificity for a probable diagnosis of Post-Traumatic Stress Disorder (PTSD), Complex-PTSD (CPTSD), depression, and generalized anxiety disorder (GAD). We also established evidence for the convergent and divergent validity of GPS. The GPS risk factors (low psychological resilience, other stressful events, history of mental illness, and low social support) contributed to predicting trauma-related symptoms after controlling for gender, age, employment status, and faculty background. Additionally, in comparison to participants from the mild and low categories of GPS symptoms scores, participants from the severe and moderate category reported impaired lowered social/work functioning. CONCLUSION: The current findings indicate that the Indonesian GPS is a valid and reliable transdiagnostic trauma screener for Indonesian undergraduate students. This first comprehensive validation of the GPS in Indonesia calls for more research in Lower-middle Income Countries (LMICs) as a way towards prevention and early intervention for trauma-related symptoms.

INTRODUCTION: The categorical approach in psychiatry has received many criticisms. Modern research tends to develop a transdiagnostic approach. However, transdiagnostic works lack an overall understanding and focus mainly on anxiety and depression. The aim of the present study was to develop an easy to use tool to evaluate multiple dimensions opening the way for further research in the transdiagnostic approach. This will allow researchers to quickly assess the efficacy of psychotherapeutic interventions on multiple psychopathological dimensions. METHOD: First, we identified the main symptoms of psychopathology in a sample of mental healthcare workers. Second, we developed the Symptomatic Transdiagnostic Test (S2T) to assess the main symptoms of psychopathology. Third, we evaluated its psychometric properties (exploratory and confirmatory factor analysis, internal consistency) in three non-clinical samples and one clinical sample. RESULTS: The 66-item S2T included eleven factors referring to: i) negative thoughts and mood; ii) psycho-traumatic and maladaptive symptoms; iii) addiction symptoms; iv) disturbed eating behavior; v) disturbed perception and behavior; vi) panic and agoraphobia; vii) emotional lability; viii) dejection; ix) neurodevelopmental manifestations; x) anxiety and xi) psychic hyperactivity. We found a high internal consistency for the general scale (α=0.96) and the subscales. We found a good concurrent validity. As expected, we found higher levels of symptoms within the clinical population as compared to the non-clinical samples, except for addiction symptoms and disrupted eating behavior. We found negative associations between the symptomatic dimensions and psychological skills. CONCLUSION: The S2T is a relevant tool for clinicians and researchers to assess the psychopathological profile. The main psychopathological symptoms are negatively related to the psychological skills.

The dense co-occurrence of psychiatric disorders questions the categorical classification tradition and motivates efforts to establish dimensional constructs with neurobiological foundations that transcend diagnostic boundaries. In this study, we examined the genetic liability for eight major psychiatric disorder phenotypes under both a disorder-specific and a transdiagnostic framework. The study sample (n = 513) was deeply phenotyped, consisting of 452 patients from tertiary care with mood disorders, anxiety disorders (ANX), attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorders, and/or substance use disorders (SUD) and 61 unaffected comparison individuals. We computed subject-specific polygenic risk score (PRS) profiles and assessed their associations with psychiatric diagnoses, comorbidity status, as well as cross-disorder behavioral dimensions derived from a rich battery of psychopathology assessments. High PRSs for depression were unselectively associated with the diagnosis of SUD, ADHD, ANX, and mood disorders (p < 1e-4). In the dimensional approach, four distinct functional domains were uncovered, namely the negative valence, social, cognitive, and regulatory systems, closely matching the major functional domains proposed by the Research Domain Criteria (RDoC) framework. Critically, the genetic predisposition for depression was selectively reflected in the functional aspect of negative valence systems (R2 = 0.041, p = 5e-4) but not others. This study adds evidence to the ongoing discussion about the misalignment between current psychiatric nosology and the underlying psychiatric genetic etiology and underscores the effectiveness of the dimensional approach in both the functional characterization of psychiatric patients and the delineation of the genetic liability for psychiatric disorders.

BACKGROUND: Sexual distress, a determinant factor in diagnosing sexual dysfunction, plays a significant role in individuals' sexual well-being, yet it has been overlooked in research. AIM: This exploratory study adopted a transdiagnostic approach to sexual distress and sought to examine the association between emotional regulation difficulties and sexual and psychological distress, with repetitive negative thinking as a potential mediator. METHODS: We used a quantitative cross-sectional design with a sample of 509 partnered individuals. OUTCOMES: The survey included a sociodemographic questionnaire, the Difficulties in Emotion Regulation Scale-Short Form, the Kessler Psychological Distress Scale, the Persistent and Intrusive Negative Thoughts Scale, and the Female Sexual Distress Scale-Revised. RESULTS: Correlational analysis revealed significant associations among emotional regulation difficulties, repetitive negative thinking, psychological distress, and sexual distress. Furthermore, a mediation model demonstrated that repetitive negative thinking significantly mediated emotion dysregulation and psychological and sexual distress. CLINICAL IMPLICATIONS: These findings underscore the importance of considering emotion regulation difficulties and repetitive negative thinking as a maladaptive coping strategy when evaluating sexual distress and suggest that therapeutic interventions targeting such difficulties and thoughts may yield beneficial outcomes. STRENGTHS AND LIMITATIONS: These findings reinforce the importance of considering the role of emotional regulation difficulties and, consequently, repetitive negative thinking as a dysfunctional coping strategy, when studying and intervening in sexual distress. Future research with clinical samples should be developed to establish better the significance of considering these two dimensions in assessment and therapeutic intervention. CONCLUSION: Future research should corroborate and expand upon these findings to advance our understanding of sexual distress and optimize interventions in this domain.

OBJECTIVE: Heightened sensitivity toward social rejection has been implicated in eating disorders (ED) and personality disorder (PD). This study examined the effect of a cognitive bias modification training (CBM-I) targeting the interpretation of ambiguous social situations in individuals with comorbid ED and PD. METHOD: A total of 128 participants [33 with ED and PD, 22 with ED-only, 22 with PD-only, and 51 healthy controls (HC)] were recruited from a hospital and university settings, and included in the final analyses. The participants were randomly assigned to a CBM-I task with benign resolutions or a control task with neutral resolutions in a counterbalanced order in two sessions using a within-subject design. Interpretation bias toward social stimuli was measured using the ambiguous sentence completion task before and after completing the assigned task. RESULTS: The CBM-I task increased benign and decreased negative interpretations with large effect sizes in the diagnostic groups, and with a moderate effect size in the HC group. Participants' anxiety levels were also reduced after the task. The size of the change in negative interpretation was positively associated with baseline negative affect, and negatively associated with baseline positive affect. DISCUSSION: The results suggest that modifying interpretation bias has the potential as a transdiagnostic target of treatment for ED and PD, and a fully powered clinical trial with consecutive sessions would be warranted. PUBLIC SIGNIFICANCE: Participants with eating disorders and/or personality disorder, and healthy controls completed a single session of a cognitive training intervention targeting rejection sensitivity. The training produced a large decrease in negative interpretation in the diagnostic groups, and a moderate effect in healthy controls. The findings indicate that training for positive processing of social information may be of value to augment treatment in conditions such as eating disorders and personality disorder, in which there are high levels of rejection sensitivity.

Characterizing patterns of mental phenomena in epidemiological studies of adolescents can provide insight into the latent organization of psychiatric disorders. This avoids the biases of chronicity and selection inherent in clinical samples, guides models of shared aetiology within psychiatric disorders and informs the development and implementation of interventions. We applied Gaussian mixture modelling to measures of mental phenomena from two general population cohorts: the Avon Longitudinal Study of Parents and Children (ALSPAC, n = 3018) and the Neuroscience in Psychiatry Network (NSPN, n = 2023). We defined classes according to their patterns of both positive (e.g. wellbeing and self-esteem) and negative (e.g. depression, anxiety, and psychotic experiences) phenomena. Subsequently, we characterized classes by considering the distribution of diagnoses and sex split across classes. Four well-separated classes were identified within each cohort. Classes primarily differed by overall severity of transdiagnostic distress rather than particular patterns of phenomena akin to diagnoses. Further, as overall severity of distress increased, so did within-class variability, the proportion of individuals with operational psychiatric diagnoses. These results suggest that classes of mental phenomena in the general population of adolescents may not be the same as those found in clinical samples. Classes differentiated only by overall severity support the existence of a general, transdiagnostic mental distress factor and have important implications for intervention.

About a decade ago, the National Institute of Mental Health (NIMH) proposed an innovative framework, the Research Domain Criteria (RDoC), to classify psychiatric disorders. This complementary approach has been used with existing diagnostic systems to identify transdiagnostic factors that inform early detection of mental health disturbances and critically, provide novel targets for interventions. An additional goal, however, has been to clarify developmental processes and illness trajectories by operationalizing dimensional constructs during sensitive periods of neurofunctional development to capture the early emergence of behavioral alterations and impairment. As developmental factors are inherent to all RDoC systems and the units of analysis therein, NIMH shepherded developmental-oriented research with targeted funding opportunity announcements. This resulting work has highlighted promising phenotypes and biological markers related to psychiatric illness across the lifespan.

OBJECTIVES: Patients admitted to psychiatric emergency services (PES) are highly heterogenous. New tools based on a transdiagnosis approach could help attending psychiatrists in their evaluation process and treatment planning. The goals of this study were to: (1) identify profiles of symptoms based on self-reported, dimensional outcomes in psychiatric patients upon their admission to PES, (2) link these profiles to developmental variables, that is, history of childhood abuse (CA) and trajectories of externalizing behaviours (EB), and (3) test whether this link between developmental variables and profiles was moderated by sex. METHODS: In total, 402 patients were randomly selected from the Signature Biobank, a database of measures collected from patients admitted to the emergency of a psychiatric hospital. A comparison group of 92 healthy participants was also recruited from the community. Symptoms of anxiety, depression, alcohol and drug abuse, impulsivity, and psychosis as well as CA and EB were assessed using self-reported questionnaires. Symptom profiles were identified using cluster analysis. Prediction of profile membership by sex, CA, and EB was tested using structural equation modelling. RESULTS: Among patients, four profiles were identified: (1) low level of symptoms on all outcomes, (2) high psychotic symptoms, (3) high anxio-depressive symptoms, and (4) elevated substance abuse and high levels of symptoms on all scales. An indirect effect of CA was found through EB trajectories: patients who experienced the most severe form of CA were more likely to develop chronic EB from childhood to adulthood, which in turn predicted membership to the most severe psychopathology profile. This indirect effect was not moderated by sex. CONCLUSION: Our results suggest that a transdiagnostic approach allows to highlight distinct clinical portraits of patients admitted to PES. Importantly, developmental factors were predictive of specific profiles. Such transdiagnostic approach is a first step towards precision medicine, which could lead to develop targeted interventions.

BACKGROUND: Low self-esteem (LSE) has been associated with several psychiatric disorders, and is presumably influenced by transdiagnostic factors. Our study was based both on investigations of the relationship between depression and LSE (vulnerability, scar, reciprocal models) and on theories of cognitive factors contributing to the development and maintenance of LSE, such as Melanie Fennell's model, the catalyst model and the Self-Regulatory Executive Function model. AIMS: Based on the theories above, in our cross-sectional study we aimed at understanding more specifically the transdiagnostic factors that can maintain LSE in a heterogeneous clinical sample. METHOD: Six hundred and eleven out-patients were assessed by SCID-I and self-report questionnaires. The model was tested by structural equation modelling. RESULTS: Based on the fit indices, the hypothesis model did not fit the data; therefore, a modified transdiagnostic model was emerged. This model made a good fit to the data [χ2 (12, n=611)=76.471, p<.001; RMSEA=.080, CFI=.950, TLI=.913] with a strong explanatory power (adj R2=.636). Severe stressful life events and depressive symptoms lead to LSE indirectly. Self-blame, perfectionism, seeking love and hopelessness have been identified as mediating factors in the relationship between depressive symptoms and LSE. Although there was a significant correlation between state-anxiety and LSE, as well as LSE and rumination, these two factors did not fit into the model. CONCLUSIONS: The new transdiagnostic model of LSE has great potential in the treatment of various mental conditions and may serve as a guide to developing more focused and more effective therapeutic interventions.

Recently, there has been renewed interest in the application of assumptions from complex systems theory in the field of psychopathology. One assumption, with high clinical relevance, is that sudden transitions in symptoms may be anticipated by rising instability in the system, which can be detected with early warning signals (EWS). Empirical studies support the idea that this principle also applies to the field of psychopathology. The current manuscript discusses whether assumptions from complex systems theory can additionally be informative with respect to the specific symptom dimension in which such a transition will occur (e.g. whether a transition towards anxious, depressive or manic symptoms is most likely). From a complex systems perspective, both EWS measured in single symptom dynamics and network symptom dynamics at large are hypothesized to provide clues regarding the direction of the transition. Challenging research designs are needed to provide empirical validation of these hypotheses. These designs should be able to follow sudden transitions 'live' using frequent observations of symptoms within individuals and apply a transdiagnostic approach to psychopathology. If the assumptions proposed are supported by empirical studies then this will signify a large improvement in the possibility for personalized estimations of the course of psychiatric symptoms. Such information can be extremely useful for early intervention strategies aimed at preventing specific psychiatric problems.

Converging evidence points to minority stress as a risk factor that predisposes sexual minority individuals to a variety of negative psychosocial health outcomes, particularly depression and anxiety, substance use, and sexual risk-taking. This paper outlines the techniques and theoretical underpinnings for implementing an emerging empirically supported psychotherapy targeting the transdiagnostic mechanisms linking minority stress with these outcomes for sexual minority clients. We outline the essential therapeutic principles, psychoeducation content, as well as session- and homework-based activities that can be adapted for a variety of presenting problems that originate from and are exacerbated by minority stress via these transdiagnostic minority stress processes. As the development and dissemination of this therapeutic model is still within its early stages, we review the intervention's empirical support thus far and outline potential directions for future development and dissemination via individual, clinic-based, and societal channels.
RESUMEN
By means of a novel methodology that can statistically derive patterns of co-alterations distribution from voxel-based morphological data, this study analyzes the patterns of brain alterations of three important psychiatric spectra-that is, schizophrenia spectrum disorder (SCZD), autistic spectrum disorder (ASD), and obsessive-compulsive spectrum disorder (OCSD). Our analysis provides five important results. First, in SCZD, ASD, and OCSD brain alterations do not distribute randomly but, rather, follow network-like patterns of co-alteration. Second, the clusters of co-altered areas form a net of alterations that can be defined as morphometric co-alteration network or co-atrophy network (in the case of gray matter decreases). Third, within this network certain cerebral areas can be identified as pathoconnectivity hubs, the alteration of which is supposed to enhance the development of neuronal abnormalities. Fourth, within the morphometric co-atrophy network of SCZD, ASD, and OCSD, a subnetwork composed of eleven highly connected nodes can be distinguished. This subnetwork encompasses the anterior insulae, inferior frontal areas, left superior temporal areas, left parahippocampal regions, left thalamus and right precentral gyri. Fifth, the co-altered areas also exhibit a normal structural covariance pattern which overlaps, for some of these areas (like the insulae), the co-alteration pattern. These findings reveal that, similarly to neurodegenerative diseases, psychiatric disorders are characterized by anatomical alterations that distribute according to connectivity constraints so as to form identifiable morphometric co-atrophy patterns.

BACKGROUND: There is evidence that anxiety is common, perhaps even more prevalent than depression, in the post-partum period. In this review we propose adopting a transdiagnostic approach to perinatal mental health: to delineate psychopathology and identify potential underlying cognitive mechanisms such as repetitive negative thinking (RNT). SAMPLING AND METHODS: We provide an overview of key studies of RNT in perinatal mental health and suggest directions for future work. We propose the value of examining post-partum depression and anxiety, and their co-occurrence, and of testing whether the psychological mechanisms that predict and maintain depression and anxiety also play a role in these conditions in the post-partum period. Further, given that psychological distress often first emerges in the antenatal phase, we make a case for investigating RNT across the perinatal period - i.e., in antenatal and postnatal women. RESULTS AND CONCLUSIONS: RNT may be a modifiable risk factor which can be targeted in pregnancy to prevent depression and anxiety in new mothers.

An understanding of etiological and maintaining factors of mental disorders is essential for the treatment of mental disorders, as well as mental health promotion and protection. The present study examines predictors of the incidence, remission and relapse of a wide range of Axis I mental disorders, using data from the Dresden Predictor Study. A sample of 1394 young German women completed questionnaires evaluating psychological factors (positive mental health, self-efficacy, life satisfaction, neuroticism, psychopathology and dysfunctional attitudes) and global assessment of functioning, as well as structured diagnostic interviews assessing incidence and change (remission, relapse) in mental disorders. Predictors were analysed using a multivariate logistic regression model. Significant factors for incidence of mental disorders included neuroticism and global functioning. A remitting course of mental disorders was predicted by positive mental health, self-efficacy and global assessment of functioning. Relapse was significantly predicted by neuroticism and dysfunctional attitudes. Results imply that mental health promotion is particularly important for women with high neuroticism and low functioning, as they tend to be at risk for incidence. Mental disorder treatment may benefit from strengthening positive mental health and functioning, as these factors promote remission. Relapse-prevention may benefit from attention to neuroticism and dysfunctional attitudes in order to reduce the likelihood of relapse. Copyright © 2016 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Incidence of mental disorders in young women was predicted by neuroticism and low global functioning. There seems to be a need for preventive interventions addressing high neuroticism and low global functioning. Remission in young women was predicted by positive mental health. It may be helpful to include resource-based interventions, which can strengthen or support general positive mental health. Relapse in young women was predicted by two negative psychological factors: high neuroticism and reporting many dysfunctional attitudes. Psychotherapy addressing the characteristics and behaviour of neurotic patients might be beneficial. Interventions should also focus on addressing and changing dysfunctional attitudes.

UNLABELLED: Dysfunctional use of the mobile phone has often been conceptualized as a 'behavioural addiction' that shares most features with drug addictions. In the current article, we challenge the clinical utility of the addiction model as applied to mobile phone overuse. We describe the case of a woman who overuses her mobile phone from two distinct approaches: (1) a symptom-based categorical approach inspired from the addiction model of dysfunctional mobile phone use and (2) a process-based approach resulting from an idiosyncratic clinical case conceptualization. In the case depicted here, the addiction model was shown to lead to standardized and non-relevant treatment, whereas the clinical case conceptualization allowed identification of specific psychological processes that can be targeted with specific, empirically based psychological interventions. This finding highlights that conceptualizing excessive behaviours (e.g., gambling and sex) within the addiction model can be a simplification of an individual's psychological functioning, offering only limited clinical relevance. KEY PRACTITIONER MESSAGE: The addiction model, applied to excessive behaviours (e.g., gambling, sex and Internet-related activities) may lead to non-relevant standardized treatments. Clinical case conceptualization allowed identification of specific psychological processes that can be targeted with specific empirically based psychological interventions. The biomedical model might lead to the simplification of an individual's psychological functioning with limited clinical relevance.

Objectives: Increasing psychological flexibility is considered an important mechanism of change in psychotherapy across diagnoses. In particular, Acceptance and Commitment Therapy (ACT) primarily aims at increasing psychological flexibility in order to live a more fulfilling and meaningful life. The purpose of this study is to examine 1) how psychological flexibility changes during an ACT-based treatment in a transdiagnostic day hospital and 2) how this change is related to changes in symptomatology, quality of life, and general level of functioning. Methods: 90 patients of a psychiatric day hospital participated in the study. Psychological flexibility, symptomatology, and quality of life were assessed at three measurement time points (admission, discharge, and 3-month follow-up). The level of functioning was assessed at admission and discharge. Differences in psychological flexibility were tested via two-sided paired samples t-tests. Correlations of residualized change scores were calculated to detect associations between changes in psychological flexibility and other outcomes. Results: Psychological flexibility increased significantly from pre-treatment to post-treatment (d = .43, p <.001) and from pre-treatment to follow-up (d = .54, p <.001). This change was significantly correlated to a decrease in symptomatology (r = .60 -.83, p <.001) and an increase in most dimensions of quality of life (r = -.43 - -.75, p <.001) and general level of functioning (r =-.34, p = .003). Discussion: This study adds further evidence for psychological flexibility as a transdiagnostic process variable of successful psychotherapy. Limitations are discussed.
RESUMEN
Objective: Existing neuroimaging studies of psychotic and mood disorders have reported brain activation differences (first-order properties) and altered pairwise correlation-based functional connectivity (second-order properties). However, both approaches have certain limitations that can be overcome by integrating them in a pairwise maximum entropy model (MEM) that better represents a comprehensive picture of fMRI signal patterns and provides a system-wide summary measure called energy. This study examines the applicability of individual-level MEM for psychiatry and identifies image-derived model coefficients related to model parameters. Method: MEMs are fit to resting state fMRI data from each individual with schizophrenia/schizoaffective disorder, bipolar disorder, and major depression (n=132) and demographically matched healthy controls (n=132) from the UK Biobank to different subsets of the default mode network (DMN) regions. Results: The model satisfactorily explained observed brain energy state occurrence probabilities across all participants, and model parameters were significantly correlated with image-derived coefficients for all groups. Within clinical groups, averaged energy level distributions were higher in schizophrenia/schizoaffective disorder but lower in bipolar disorder compared to controls for both bilateral and unilateral DMN. Major depression energy distributions were higher compared to controls only in the right hemisphere DMN. Conclusions: Diagnostically distinct energy states suggest that probability distributions of temporal changes in synchronously active nodes may underlie each diagnostic entity. Subject-specific MEMs allow for factoring in the individual variations compared to traditional group-level inferences, offering an improved measure of biologically meaningful correlates of brain activity that may have potential clinical utility.
RESUMEN
Aims: To map studies assessing both clinical high risk for psychosis (CHR-P) and borderline personality disorder (BPD) in clinical samples, focusing on clinical/research/preventive paradigms and proposing informed research recommendations. Methods: We conducted a PRISMA-ScR/JBI-compliant scoping review (protocol: https://osf.io/8mz7a) of primary research studies (cross-sectional/longitudinal designs) using valid measures/criteria to assess CHR-P and BPD (threshold/subthreshold) in clinical samples, reporting on CHR-P/psychotic symptoms and personality disorder(s) in the title/abstract/keywords, identified in Web of Science/PubMed/(EBSCO)PsycINFO until 23/08/2023. Results: 33 studies were included and categorized into four themes reflecting their respective clinical/research/preventive paradigm: (i) BPD as a comorbidity in CHR-P youth (k = 20), emphasizing early detection and intervention in psychosis; (ii) attenuated psychosis syndrome (APS) as a comorbidity among BPD inpatients (k = 2), with a focus on hospitalized adolescents/young adults admitted for non-psychotic mental disorders; (iii) mixed samples (k = 7), including descriptions of early intervention services and referral pathways; (iv) transdiagnostic approaches (k = 4) highlighting "clinical high at risk mental state" (CHARMS) criteria to identify a pluripotent risk state for severe mental disorders. Conclusion: The scoping review reveals diverse approaches to clinical care for CHR-P and BPD, with no unified treatment strategies. Recommendations for future research should focus on: (i) exploring referral pathways across early intervention clinics to promote timely intervention; (ii) enhancing early detection strategies in innovative settings such as emergency departments; (iii) improving mental health literacy to facilitate help-seeking behaviors; (iv) analysing comorbid disorders as complex systems to better understand and target early psychopathology; (v) investigating prospective risk for BPD; (vi) developing transdiagnostic interventions; (vii) engaging youth with lived experience of comorbidity to gain insight on their subjective experience; (viii) understanding caregiver burden to craft family-focused interventions; (ix) expanding research in underrepresented regions such as Africa and Asia, and; (x) evaluating the cost-effectiveness of early interventions to determine scalability across different countries.

RESUMEN
Purpose: The main purpose of the article is to present basic theoretical assumptions on Schema Therapy and its hypothetical application among adolescents suffering with anorexia nervosa. Views: Anorexia nervosa is a very deadly mental disease, more frequently suffered by females than males, with the mean age of onset at approximately 14-15. Studies underline the relatively poor effectiveness of currently applied treatment methods and the need for new approaches that could be recommended for adolescent patients suffering with this disease. The results of studies conducted to date lead to the conclusion that Schema Therapy is a promising approach for this group. It is a transdiagnostic method of work that compiles elements known in other therapeutic approaches, aiming at an increase in the individual's awareness of their feelings and emotional needs, applied both in adolescent and adult groups of patients. Since the symptoms of eating disorders observed in adolescents are strongly connected with family systems it seems reasonable to use treatment techniques that rigorously address the unmet needs and rejected emotions of the individual. Conclusions: Based on the data published so far it might be hypothesized that the techniques characteristic for Schema Therapy (e.g. imagery rescripting, chairwork, limited reparenting) could be eligible for use with adolescent patients with anorexia nervosa.They address unmet needs, rejected emotions, and early maladaptive schemas that are very frequent in patients with AN. Since the analysis presented provides only hypotheses and the discussion of theoretical aspects, empirical research in this area is needed.
