Comorbid depressive and anxiety disorders in 509 individuals with an at-risk mental state: impact on psychopathology and transition to psychosis

Adaptation of a Psychosocial Intervention for Canadian Youth at Clinical High Risk for Psychosis: Adaptation d'une intervention psychosociale pour les jeunes à haut risque clinique de psychose au Canada

Aim: This paper provides a detailed account of the process and outcomes involved in adapting a psychosocial intervention - the Optimal Health Program (OHP) - for young individuals who are at clinical high risk (CHR) for psychosis. This adaptation process included the active participation of youth with lived experience of psychosis spectrum disorder (CHR and first episode psychosis). Methods: A six-member advisory group consisting of youth with lived experience was established. The group convened weekly to review the OHP workbook in detail. This initiative was supported by a dedicated research assistant. Adherence to established guidelines for engaging with youth was maintained throughout. Following the completion of the adaptation, a review session was conducted to gather feedback. Results: The primary adaptations made to the intervention can be categorized as follows: 1) modification of language; 2) tailoring to the CHR population; 3) incorporation of personal stories; 4) emphasis on personalized recovery; 5) inclusion of 'guiding and supportive activities'; 6) enhancement of graphic design. Suggestions for a digital application were not integrated due to their scope extending beyond the aims of the current project. An assessment of the engagement process revealed that the involvement of youth was meaningful and impactful. Conclusions: Through sustained and meaningful engagement with youth with lived experience, the present project adapted OHP for CHR individuals. The resulting intervention materials are anticipated to be closely aligned with the distinct needs and priorities of young CHR individuals. Subsequent endeavours in developing appropriate interventions that aim to improve outcomes for this population should involve engaging and collaborating with individuals with lived experience. We are currently in the process of evaluating the feasibility, acceptability, and preliminary efficacy of delivering OHP to individuals with CHR in a clinical trial.

Sample ascertainment and clinical outcome measures in the Accelerating Medicines Partnership® Schizophrenia Program

Clinical ascertainment and clinical outcome are key features of any large multisite study. In the ProNET and PRESCIENT research networks, the Accelerating Medicines Partnership® Schizophrenia (AMP®SCZ) Clinical Ascertainment and Outcome Measures Team aimed to establish a harmonized clinical assessment protocol across these two research networks and to define ascertainment criteria and primary and secondary endpoints. In addition to developing the assessment protocol, the goals of this aspect of the AMP SCZ project were: (1) to implement and monitor clinical training, ascertainment of participants, and clinical assessments; (2) to provide expert clinical input to the Psychosis Risk Evaluation, Data Integration and Computational Technologies: Data Processing, Analysis, and Coordination Center (PREDICT-DPACC) for data collection, quality control, and preparation of data for the analysis of the clinical measures; and (3) to provide ongoing support to the collection, analysis, and reporting of clinical data. This paper describes the (1) protocol clinical endpoints and outcomes, (2) rationale for the selection of the clinical measures, (3) extensive training of clinical staff, (4) preparation of clinical measures for a multisite study which includes several sites where English is not the native language; and (5) the assessment of measure stability over time in the AMP SCZ observational study comparing clinical ratings at baseline and at the 2-month follow up.

Insights into psychosis risk: Unveiling impaired reinforcement learning through a behavioral and functional near-infrared spectroscopy-based optical neuroimaging study

BACKGROUND

Reward processing is crucial for learning, motivation and decision-making, and can be disturbed in the development of psychosis. Previous research has linked cognitive impairment and abnormalities in brain function to the clinical high risk state of psychosis (CHR-P). However, the extent to which processes of cognitive flexibility in response to reward feedback are impaired in CHR-P compared to healthy control (HC) individuals is largely unknown.

METHODS

To address this knowledge gap, we conducted a probabilistic reward task in 59 people with CHR-P (age: 18.89 ± 0.66 years, 54% female) from the Bern Early Recognition and Intervention Center, and 24 HC (age: 19.37 ± 1.20 years, 50% female). In addition, we recorded the prefrontal neurovascular response of the subjects using functional near-infrared spectroscopy (fNIRS) neuroimaging during task performance.

RESULTS

Behavioral results of the probabilistic reward task showed that CHR-P subjects had a significantly lower propensity for reward feedback compared to HC subjects, especially in the later course of the task (p = 0.018, Cohen's d = 0.58). When comparing the fNIRS measurements, we found a significantly lower task-induced increase in total hemoglobin concentration ([tHb]) in CHR-P subjects compared to HC subjects (p = 0.049).

CONCLUSIONS

Our findings indicate impaired reward feedback processing in CHR-P subjects, suggesting reduced sensitivity to reward. This is reflected in decreased task-induced response in cerebrovascular [tHb], indicating lower task-relevant prefrontal activities compared to HC subjects. These findings suggest that impaired processing of reward feedback may contribute to reward learning deficits and inflexible cognition in CHR-P subjects.

Development of the Clinical High Risk for Psychosis Services Fidelity Scale (CHRPS-FS) for Team-Based Care

OBJECTIVE

This study aimed to develop and pilot the Clinical High Risk for Psychosis Services Fidelity Scale (CHRPS-FS).

METHODS

A literature review was conducted to identify evidence-based treatments for individuals at clinical high risk for psychosis (CHRP). These findings were compared with the First-Episode Psychosis Services Fidelity Scale (FEPS-FS). Common items were retained, and others were added, modified, or deleted. Next, the Delphi process was conducted with 17 clinical and academic experts in CHRP care to determine consensus on the importance and validity of each item. Concurrently, the preliminary tool was piloted in eight coordinated specialty care (CSC) clinics serving individuals with CHRP.

RESULTS

The literature review identified two components of CHRP care that were not detailed in the FEPS-FS and were added to the CHRPS-FS; furthermore, one FEPS-FS item was modified and six were removed. In the Delphi process, clinical and academic experts achieved a consensus of >80% in two rounds, with some changes in item wording and the addition of one item (stepped care approach). A CHRPS-FS assessment was successfully piloted in eight CSC clinics. The mean CHRPS-FS rating score was 3.96 (range 3.75-4.23), and the median proportion of items rated at good to high fidelity was 72% (range 66%-78%).

CONCLUSIONS

The CHRP-FS is feasible to implement, has face validity based on expert consensus, can be completed in conjunction with a FEPS-FS assessment or alone, and captures variability across programs. The CHRPS-FS measures service delivery and is suitable for clinical trials, learning health care systems, and quality improvement efforts.

Exercise as a transdiagnostic intervention for improving mental health: An umbrella review

Exercise is beneficial for mental health in general, but no review has systematically assessed its potential transdiagnostic nature, i.e. whether it is beneficial across specific disorders. We performed a systematic umbrella review of meta-analyses of randomized controlled trials (RCTs) of exercise in participants with mental disorders defined according to the International Classification of Diseases (ICD) or the Diagnostic and Statistical Manual of Mental Disorders (DSM), assessing exercise's transdiagnostic nature with TRANSD criteria, including eight meta-analyses (six included in the TRANSD meta-analysis), encompassing 99 RCTs (n = 5,656) across 11 disorders. Moderate/vigorous aerobic exercise was an effective transdiagnostic intervention for disease-specific primary symptoms across 11 disorders (recurrent depressive disorder, social phobia, panic disorder, generalized anxiety disorder, post-traumatic stress disorder, brief psychotic disorder, schizophrenia, schizoaffective disorder, delusional disorder, schizophreniform disorder, attention-deficit/hyperactivity disorder) and four spectra (depressive disorders, anxiety disorders, schizophrenia-spectrum disorders, neurodevelopmental disorders) with a medium effect size (SMD = -0.67, 95%CI = -0.84, -0.50). Moderate/vigorous aerobic exercise also improved cognition across two disorders (schizophrenia, attention-deficit/hyperactivity disorder) and two spectra (schizophrenia-spectrum disorders, neurodevelopmental disorders), with a large effect size (SMD = 0.92, 95%CI = 0.52, 1.33). According to TRANSD criteria, moderate/vigorous aerobic exercise is a transdiagnostic intervention to improve disease-specific primary symptoms of 11 mental disorders, and cognition in two mental disorders.

Schizotypal Traits, Psychopathology, and Reflective Functioning Impairments During Adolescence: A Bayesian Network Approach

BACKGROUND

New theoretical and measurement models related to Bayesian networks can usefully be implemented to enrich our understanding of psychosis risk. The present study aims to explore, using a directed acyclic graph (DAG), the putative causal relationship within schizotypal facets, as well as between schizotypal dimensions, psychopathology, and reflective functioning (RF) impairments, in a representative sample of non-clinical adolescents.

STUDY DESIGN

A sample of 1476 adolescents from the general population participated in a cross-sectional survey. The Oviedo Schizotypy Assessment Questionnaire-Revised, the Strengths and Difficulties Questionnaire, and the Reflective Functioning Questionnaire (RFQ) were used.

STUDY RESULTS

Schizotypal traits were positively associated with psychopathology and hypomentalizing. Putative causal relationships are presented between Reality distortion, Social disorganization, and Anhedonia. In addition, estimated DAG suggests that schizotypal dimensions influence psychopathology and RF impairments.

CONCLUSIONS

The findings suggest different pathways connecting schizotypal traits, mental health problems, and RF impairments during adolescence. The use of probabilistic DAG may allow us to make more robust conclusions about the direction of causation and to unravel potentially complex causal chains in the study of psychosis risk.

Relationship Between Schizotypal Traits, Emotion Regulation, and Negative Affect in Children: A Network Analysis

BACKGROUND AND HYPOTHESIS

Evidence suggests that emotion regulation is related to schizotypal traits and negative affect in adults. Few studies examined the interplay among these constructs in school-aged children. We examined the complex relationship between schizotypal traits, emotion regulation, and negative affect in children aged 9-12 years.

STUDY DESIGN

One-thousand-and-nineteen children completed the Schizotypal Personality Questionnaire-children (SPQ-C), the Depression Anxiety Stress Scales (DASS-21), and the Emotion Regulation Questionnaire for Children and Adolescence (ERQ-CA). Using subscales of these measures as nodes, we estimated a partial correlation network. We estimated a Directed Acyclic Graph to explore the putative directional relationship between schizotypal traits, emotion regulation, and negative affect. Node and bridge centrality indices were estimated.

RESULTS

We found positive correlations between schizotypal dimensions and negative affect (depressed mood, anxiety, and stress) in the network. Emotion suppression was positively correlated with interpersonal and disorganized schizotypal dimensions, and negative affect. Emotion reappraisal was positively correlated with the cognitive-perceptual dimension and negatively correlated with interpersonal schizotypal traits, depressed mood, and stress. Stress showed higher strength than all nodes except depressed mood, and stress showed the highest expected influence (EI). The Bayesian network revealed that schizotypal traits appeared to be driven by stress. Network comparisons preliminarily showed higher EI for emotion reappraisal in girls' than boys' networks, and significant impacts of age and schizotypy levels on network patterns.

CONCLUSION

Children with higher levels of schizotypal traits may have more negative affect and suppression. Stress appears to drive schizotypal traits.

"Young People Come to Youth Workers First": A Mixed Methods Evaluation of the Role of Youth Workers in Youth Psychosis Detection

INTRODUCTION

Reducing the duration of untreated psychosis (DUP) is a cornerstone of effective early intervention for psychosis (EIP) services. Delays in help seeking are a significant component of DUP, particularly among youth. Given their role as trusted adults in young people's lives, youth workers are uniquely positioned to play a role in early detection networks. However, their views regarding this remain largely unexamined.

AIM

This study aimed to explore youth workers' perspectives on identifying and responding to psychosis in youth and the training needed to support them in this role.

METHODS

A sequential-independent mixed methods design was employed. A brief questionnaire was given to youth workers (n = 86) who attended a 1-day EIP training session, followed by semi-structured interviews with a subset of participants (n = 10) 3 months later.

RESULTS

Most participants (98.8%) expressed confidence in recognising psychosis; however, stigma and challenging relationships with mental health services emerged as systemic barriers. Although most participants (98.8%) found the EIP training relevant to their role, they suggested it should form part of a broader mental health curriculum. There was a clear consensus among participants that such training is necessary and should be accessible, practical and actionable.

CONCLUSION

Youth workers are uniquely positioned in identifying and supporting young people at risk of psychosis, and this study underscores their willingness to take on this role. To best support them, training efforts should focus on trans-diagnostic approaches that enhance mental health literacy, address systemic barriers and promote multidisciplinary partnerships.

Probabalistic reinforcement learning impairments predict negative symptom severity and risk for conversion in youth at clinical high-risk for psychosis

BACKGROUND

Elucidation of transphasic mechanisms (i.e., mechanisms that occur across illness phases) underlying negative symptoms could inform early intervention and prevention efforts and additionally identify treatment targets that could be effective regardless of illness stage. This study examined whether a key reinforcement learning behavioral pattern characterized by reduced difficulty learning from rewards that have been found to underlie negative symptoms in those with a schizophrenia diagnosis also contributes to negative symptoms in those at clinical high-risk (CHR) for psychosis.

METHODS

CHR youth (n = 46) and 51 healthy controls (CN) completed an explicit reinforcement learning task with two phases. During the acquisition phase, participants learned to select between pairs of stimuli probabilistically reinforced with feedback indicating receipt of monetary gains or avoidance of losses. Following training, the transfer phase required participants to select between pairs of previously presented stimuli during the acquisition phase and novel stimuli without receiving feedback. These test phase pairings allowed for inferences about the contributions of prediction error and value representation mechanisms to reinforcement learning deficits.

RESULTS

In acquisition, CHR participants displayed impaired learning from gains specifically that were associated with greater negative symptom severity. Transfer performance indicated these acquisition deficits were largely driven by value representation deficits. In addition to negative symptoms, this profile of deficits was associated with a greater risk of conversion to psychosis and lower functioning.

CONCLUSIONS

Impairments in positive reinforcement learning, specifically effectively representing reward value, may be an important transphasic mechanism of negative symptoms and a marker of psychosis liability.

Investigating the associations between personality functioning, cognitive biases, and (non-)perceptive clinical high-risk symptoms of psychosis in the community

BACKGROUND

Beyond psychosis prediction, clinical high-risk (CHR-P) symptoms show clinical relevance by their association with functional impairments and psychopathology, including personality pathology. Impaired personality functioning is prioritized in recent dimensional personality disorder models (DSM-5, ICD-11), yet underexplored in CHR-P, as are associations with cognitive biases, which early studies indicate as possibly linking CHR-P-symptoms and personality pathology.

METHODS

A community sample (N = 444, 17-60 years, 61.8% female) was assessed via clinical telephone interview and online questionnaires. Using zero-inflated Poisson models, we explored associations of personality functioning, cognitive biases, current psychopathology, and psychosocial functioning with likelihood and severity of overall CHR-P, as well as perceptive (per-) and non-perceptive (nonper-)CHR-P-symptoms distinctly.

RESULTS

Higher nonper-CHR-P-symptom likelihood was associated with more impaired personality functioning and psychosocial functioning, while more severe cognitive biases were associated with higher CHR-P- and per-CHR-P-symptom likelihood, alongside higher CHR-P- and nonper-CHR-P-symptom severity. Further, more axis-I diagnoses were linked to higher CHR-P-, per-CHR-P-, and nonper-CHR-P-symptom likelihood, and younger age to higher CHR-P- and per-CHR-P-symptom severity, with CHR-P-symptom severity appearing higher in females. In an exploratory analysis, personality functioning elements identity and self-direction, and cognitive biases dichotomous thinking, emotional reasoning, and catastrophizing, respectively, showed multifaceted associations with nonper-CHR-P-symptom likelihood and overall CHR-P-symptom expression.

CONCLUSIONS

Our study supports the association of CHR-P-symptoms with multiple mental health factors. Findings suggest intricate associations between personality functioning impairments and cognitive biases with CHR-P-symptom expression in non-help-seeking populations, possibly contributing to different per-CHR-P- and nonper-CHR-P-symptom expression patterns. Therefore, they should be targeted in future longitudinal studies, aiming at better understanding CHR-P-manifestations to inform preventive intervention.

Identifying clinical and proteomic markers for early diagnosis and prognosis prediction of major psychiatric disorders

BACKGROUND

To clarify if blood proteins can predict disease progression among individuals at clinical high-risk of severe mental illness (CHR-SMI), we developed a statistical model incorporating clinical and blood protein markers to distinguish the transition group (who developed severe mental illness) (CHR-SMI-T) and from non-transition group (CHR-SMI-NT) at baseline.

METHODS

Ninety individuals (74 at CHR-SMI: 16 patients) were monitored for ≤4 years and were the focus of predictive models. Three predictive models (1 [100 clinical variables], 2 [158 peptides], and 3 [100 clinical variables +158 peptides]) were evaluated using area under the receiver operating characteristic (AUROC) values. Clinical and protein feature patterns were evaluated by linear mixed-effect analysis within the model at 12 and 24 months among patients who did (CHR-SMI-T) and did not transition (CHR-SMI-NT) and the entire group.

RESULT

Eighteen CHR-SMI individuals with major psychiatric disorders (first episode psychosis: 2; bipolar II disorder: 13; major depressive disorder; 3) developed disorders over an average of 17.7 months. The combined model showed the highest discriminatory performance (AUROC = 0.73). Cytosolic malate dehydrogenase and transgelin-2 levels were lower in the CHR-SMI-T than the CHR-SMI-NT group. Complement component C9, inter-alpha-trypsin inhibitor heavy chain H4, von Willebrand factor, and C-reactive protein were lower in the patient than the CHR-SMI-NT group. These differences were non-significant after FDR adjustment.

LIMITATIONS

Small sample, no control for medication use.

CONCLUSION

This exploratory study identified clinical and proteomic markers that might predict severe mental illness early onset, which could aid in early detection and intervention. Future studies with larger samples and controlled variables are needed to validate these findings.

Social defeat predicts the emergence of psychotic-like experiences through the effects on aberrant salience: insights from a network analysis of longitudinal data

BACKGROUND

Psychotic-like experiences (PLEs) are subclinical phenomena that often precede the onset of psychosis and occur in various mental disorders. Social determinants of psychosis and PLEs are important and have been operationalized within the social defeat (SD) hypothesis. The SD hypothesis posits that low social status and exposure to repeated humiliation can lead to imbalanced dopamine neuron activity, and thus increased risk of psychosis. We aimed to assess the role of dynamic interactions between SD components in shaping the occurrence of PLEs using a network analysis.

METHODS

A total of 2241 non-clinical, young adults were assessed at baseline and invited for reassessment after a 6-month follow-up. Self-reports recording the occurrence of PLEs, aberrant salience (AS), depressive, and anxiety symptoms as well as SD characteristics (socioeconomic status, minority status, humiliation, perceived constraints, and domain control) were administered. Two networks were analyzed (the first one covering all baseline measures and the second one with the baseline SD components and follow-up measures of AS and psychopathology).

RESULTS

The SD components were not directly connected to the measures of PLEs in both networks. However, in both networks, SD components were connected to PLEs through a mediating effect of AS. Among SD components, humiliation had the highest bridge centrality across three predefined communities of variables (SD; depressive and anxiety symptoms; AS, and PLEs).

CONCLUSIONS

The findings indicate that SD might make individuals vulnerable to develop PLEs through the mediating effects of AS. Among SD components, humiliation might play the most important role in the development of PLEs.

Overlap of obsessive compulsive and psychosis risk symptoms in a specialized clinic

AIM

Psychotic disorders and obsessive-compulsive disorder (OCD) commonly co-occur. Likewise, subthreshold psychosis symptoms (clinical high risk for psychosis; CHR) and obsessive compulsive symptoms (OCS) often overlap and may be difficult to differentiate. This study aimed to replicate research investigating the prevalence of OCD in a CHR clinic sample, validate and investigate factor structure of a self-report OCS measure in a CHR sample, explore how OCS may relate to CHR and co-occurring symptoms, and investigate whether real-world CHR treatment improves OCS and CHR symptoms.

METHOD

This study analysed archival clinical data from baseline and 6-month follow-up assessments collected by a specialist outpatient CHR clinic. Data included assessments of CHR symptoms, OCS, and clinician-rated diagnosis. Exploratory factor analysis examined the OCS measure.

RESULTS

Within this CHR clinic sample, 13.5% experienced co-morbid OCD. The self-report OCS measure had two factors: (1) checking and counting behaviours and (2) intrusive thoughts and images of harm/guilt. The checking and counting factor correlated with depression and social anxiety. The intrusive thoughts and images of harm/guilt factor significantly correlated with unusual thought content and social anxiety. Between baseline to 6-month follow-up, clients exhibited CHR symptom improvement regardless of OCD diagnosis. However, OCS did not change.

CONCLUSIONS

These findings support validity of a self-report OCS measure in a CHR clinic sample and that types of OCS experiences may exhibit different clinical patterns. Additionally, it appears that individuals with comorbid OCD responded similarly to CHR treatment compared to those without OCD.

Do help-seeking adolescents report more psychotic-like experiences than young adults on the 16-item version of the prodromal questionnaire (PQ-16)?

AIM

To compare psychotic-like experiences (PLEs) in adolescents and young adults referred to the Mental Health Services (MHSs).

METHODS

Participants scored the 16-item Prodromal Questionnaire (PQ-16) as part of the intake procedure. Data on the Diagnostic and Statistical Manual of Mental Disorders (DSM) classification and demographic data were collected.

RESULTS

The PQ-16 was completed by 13 783 respondents (mean age 24.63 years, SD = 6.09; 62.6% female). Overall, the scores on the PQ-16 were not higher for adolescents (11-17 years; m = 4.84, SD = 3.62) than for young adults (18-35 years; m = 5.47, SD = 3.85). On PQ-16 item level, adolescents reported seeing and hearing things more than adults did. Across all age groups, males scored lower on the PQ-16 than females. Specifically, adolescent males scored lower than other participants. For adolescents and young adults alike, PQ-16 scores were higher for participants with borderline personality disorder, PTSD, and mood disorder than for those with other DSM classifications.

CONCLUSIONS

Although help-seeking adolescents did not score higher on the PQ-16 than help-seeking young adults, more of them reported perceptual anomalies. Irrespective of age, participants with borderline personality disorder, PTSD and mood disorder scored higher on the PQ-16 than those with other DSM classifications.

Clinical utility of the at-risk for psychosis state beyond transition: A multidimensional network analysis

To be relevant to healthcare systems, the clinical high risk for psychosis (CHR-P) concept should denote a specific (i.e., unique) clinical population and provide useful information to guide the choice of intervention. The current study applied network analyses to examine the clinical specificities of CHR-P youths compared to general help-seekers and non-CHR-P youth. 146 CHR-P (mean age = 14.32 years) and 103 non-CHR-P (mean age = 12.58 years) help-seeking youth were recruited from a neuropsychiatric unit and assessed using the Structured Interview for Psychosis-Risk Syndromes, Children's Depression Inventory, Multidimensional Anxiety Scale for Children, Global Functioning: Social, Global Functioning: Role, and Wechsler Intelligence Scale for Children/Wechsler Adult Intelligence Scale. The first network structure comprised the entire help-seeking sample (i.e., help-seekers network), the second only CHR-P patients (i.e., CHR-P network), and the third only non-CHR-P patients (i.e., non-CHR-P network). In the help-seekers network, each variable presented at least one edge. In the CHR-P network, two isolated "archipelagos of symptoms" were identified: (a) a subgraph including functioning, anxiety, depressive, negative, disorganization, and general symptoms; and (b) a subgraph including positive symptoms and the intelligence quotient. In the non-CHR-P network, positive symptoms were negatively connected to functioning, disorganization, and negative symptoms. Positive symptoms were less connected in the CHR-P network, indicating a need for specific interventions alongside those treating comorbid disorders. The findings suggest specific clinical characteristics of CHR-P youth to guide the development of tailored interventions, thereby supporting the clinical utility of the CHR-P concept.

Fear and Anxiety in Schizophrenia: A Focus on Development, Assessment, and Mechanisms

In people with schizophrenia, anxiety is highly prevalent and related to numerous negative outcomes; unfortunately, anxiety is both underreported and understudied in schizophrenia. The current review highlights the importance and utility of assessing anxiety in schizophrenia by addressing four main questions: (1) What does anxiety look like throughout the development of schizophrenia?; (2) How do we measure anxiety in schizophrenia?; (3) What are the mechanisms underlying anxiety in schizophrenia; (4) How do we treat anxiety in schizophrenia? We also provide take-home points and propose future directions for the field. We hope this emphasis on the critical role of anxiety in schizophrenia will help researchers appropriately identify the presence of anxiety, better address these symptoms, and improve the lives of people at risk for or experiencing psychosis.

Efficacy of the unified protocol for transdiagnostic treatment of comorbid emotional disorders in patients with ultra high risk for psychosis: Results of a randomized controlled trial

BACKGROUND

The most common reason for help-seeking in ultra-high risk (UHR) for psychosis patients is comorbid symptoms, mainly anxiety and depression. However, psychological interventions are mainly focused on subthreshold psychotic symptoms. There is a growing push to include transdiagnostic therapies in specialized intervention teams for psychosis in young people. The Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders (UP) has demonstrated efficacy in emotional disorders, and its application has recently expanded to other pathologies such as borderline personality disorder (BPD) and bipolar disorder (BD).

METHODS

This pilot study was conducted with 36 patients with UHR for psychosis and symptoms of comorbid emotional disorders who were receiving treatment in an early intervention programme for psychosis. This is a randomised control trial (RCT) with two conditions: treatment as usual (TAU) with the group and online application of the UP (UP+TAU) (n = 18) and TAU (n = 18). Evaluations were conducted at baseline, after treatment, and at the three-month follow-up.

RESULTS

Comorbid anxiety and depression symptoms improved significantly in patients in the UP+TAU group compared to those in the TAU. Significant improvements in negative affect, emotional dysregulation, neuroticism, extraversion, functioning, and quality of life were also observed, and satisfaction with the intervention was high.

CONCLUSIONS

UP may be an acceptable and effective intervention for the treatment of symptoms of comorbid emotional disorders in patients with UHR for psychosis.

LIMITATIONS

The sample size was small, and further studies are needed to test this intervention with larger samples of patients with UHR for psychosis with emotional comorbidities.

Neurobiological correlates of comorbidity in disorders across the affective disorders-psychosis spectrum

Disorders across the affective disorders-psychosis spectrum such as major depressive disorder (MDD), bipolar disorder (BD), schizoaffective disorder (SCA), and schizophrenia (SCZ), have overlapping symptomatology and high comorbidity rates with other mental disorders. So far, however, it is largely unclear why some of the patients develop comorbidities. In particular, the specific genetic architecture of comorbidity and its relationship with brain structure remain poorly understood. Therefore, we performed systematic analyses of clinical, genetics and brain structural measures to gain further insights into the neurobiological correlates of mental disorder's comorbidity. We investigated a sub-sample of the Marburg/Münster Cohort Study (MACS), comprising DSM-IV-TR diagnosed patients with a single disorder in the affective disorders-psychosis spectrum (SD, n = 470, MDD; BD; SCA; SCZ), with additional mental disorder's comorbidities (COM, n = 310), and healthy controls (HC, n = 649). We investigated group differences regarding a) the global severity index (based on SCL90-R), b) a cross-disorder polygenic risk score (PRS) calculated with PRS-continuous shrinkage (PRS-CS) using the summary statistics of a large genome-wide association study across mental disorders, and c) whole brain grey matter volume (GMV). The SCL90-R score significantly differed between groups (COM > SD > HC). While SD and COM did not differ in cross-disorder PRS and GMV, SD and COM versus HC displayed increased cross-disorder PRS and decreased GMV in the bilateral insula, the left middle temporal, the left inferior parietal, and several frontal gyri. Our results thus suggest that disorders in the affective disorders-psychosis spectrum with or without additional comorbidities differ in self-reported clinical data, but not on genetic or brain structural levels.

Why do some Mexicans with psychosis risk symptoms seek mental health care and others do not?

Help-seeking barriers differ according to the sociocultural context and country-specific mental healthcare system. More research is needed in low-middle-income countries, where early psychosis programs are still scarce, and the mental health care gap is wide. This study aims to explore predisposing, enabling, and need factors associated with mental health service utilization in 481 Mexicans self-reporting psychosis risk symptoms, as well as differences between those who were currently mental health service users (MHSU) and those who were not (non-MHSU). Participants responded to self-reported measures through an online survey. The factors associated with an increased probability of using mental health services were having an occupation, having a medium/high socioeconomic status, an intention to seek help from a mental health professional, fewer help-seeking barriers, moderate/severe anxious symptoms, higher distress associated with psychosis risk symptoms and social functioning impairment. Findings provide relevant information for designing more effective strategies to improve help-seeking, early identification, and timely treatment delivery in Mexico. The need to generate strategies focused on reducing stigma, enhancing psychosis literacy in the community, and increasing the identification of emerging signs of psychosis in primary healthcare professionals is highlighted, mainly when co-occurring with other psychiatric symptoms.

Mentalizing the Clinical High-Risk for Psychosis Model: A Staged Intervention Framework

This article seeks to further specify how the mentalization-based approach may inform clinical intervention before the onset of psychosis, that is, during the stage of clinical high-risk for psychosis (CHR-P). We first review the concept of CHR-P, as well as the research evidence of the impact of early intervention. Next, we present evidence for the centrality of mentalizing as a process that may mitigate the risk for psychosis. We then review some of the key contributions in the psychoanalytical and phenomenological traditions concerning the centrality of core self disturbances in psychosis, and relate this to the alien self concept put forward in the mentalization framework. This leads us to expand on the structure of MBT for CHR-P, and to present a clinical vignette illustrating the process of epistemic trust at beginning of an intervention with a young person suffering from CHR-P. We summarize the links between core self disturbances, epistemic trust, and therapeutic communication in the context of CHR-P.

Obsessive-compulsive symptoms in individuals at clinical high risk for psychosis: A 2-year longitudinal study

Aim - Recent findings suggest that OCS are prevalent in individuals with early psychosis. However, their clinical relevance still needs to be clarified. This research specifically explored OCS in subjects at Clinical High Risk for Psychosis (CHRP), with the aims of determining their baseline prevalence, examining their 2-year stability, and analyzing their association with sociodemographic data, clinical characteristics and outcomes. Methods - Clinical assessments at baseline and during the 2-year follow-up period included: the Comprehensive Assessment of At-Risk Mental states (CAARMS), the Positive And Negative Syndrome Scale (PANSS), and the Global Assessment of Functioning (GAF). OCS were identified using the CAARMS item 7.6 subscore. Results - Among 180 CHR-P participants, 66 (36.7 %) had OCS at baseline. CHR-P with OCS had higher PANSS scores and greater antidepressant prescription rates. OCS severity levels improved in the first year, but plateaued over two years, correlating with longitudinal changes in GAF and PANSS total scores. OCS improvement was specifically associated with antidepressant use and intensity of individual psychotherapy sessions. CHR-P subjects with OCS had higher service engagement rates. Conclusions - The presence of OCS could characterize a distinct CHR-P subtype with specific clinical and prognostic characteristics, requiring tailored diagnostic and therapeutic approaches. Recognizing the heterogeneity in CHR-P population is crucial for optimizing care.

Arabic translation and validation of the clinician administered Staden schizophrenia anxiety rating scale (S-SARS)

Background

Research on anxiety in patients with schizophrenia of Arab origin is surprisingly scarce, particularly given that expressions of both psychotic disorders and anxiety disorders can be largely shaped by cultural factors. This study proposes to complement previous research by exploring the psychometric characteristics of an Arabic translation of the Staden Schizophrenia Anxiety Rating Scale (S-SARS) in chronic, remitted patients diagnosed with schizophrenia. As the Arabic version of the Generalized Anxiety Disorder 7-Item Scale (GAD-7) has not been previously validated in Arabic in patients with schizophrenia, this study had as a secondary aim to investigate the psychometric properties of this scale before its use.

Method

This cross-sectional study was performed over a period of three months (August-October 2023). A total of 177 chronic inpatients diagnosed with schizophrenia (63.3 % males) who were remitted and clinically stable participated in the study.

Results

Confirmatory factor analyses showed that all 10 items loaded onto a single factor and had high factor loading values between .53 and .81. The reliability of the S-SARS in its Arabic version was excellent as attested by a McDonald's omega and a Cronbach's alpha coefficients of .90 and .89, respectively. The score of Arabic S-SARS correlated positively with the GAD-7 scores (r = .55; p < .001), thus supporting good convergent validity. As for discriminant validity, findings showed positive correlations between S-SARS and depression scores as assessed using the Calgary Depressive Symptoms Scale. In addition, the Arabic S-SARS correlated negatively with general functioning, further supporting the good validity and clinical relevance of the scale. Finally, measurement invariance was established in the sex subsamples (males vs. females) at the scalar, metric and configural levels, with females showing more anxiety than males.

Conclusion

Findings suggest that the Arabic S-SARS holds good psychometric properties, and is suitable for use among Arabic-speaking people diagnosed with schizophrenia in both research and clinical practice. The Arabic version of S-SARS will hopefully be widely applied to provide useful and timely clinical information for monitoring and adequately treating patients with schizophrenia, in order to improve the course and prognosis of the disease.

Non-psychotic Outcomes in Young People at Ultra-High Risk of Developing a Psychotic Disorder: A Long-Term Follow-up Study

BACKGROUND

The majority of individuals at ultra-high risk (UHR) for psychosis do not transition to a full threshold psychotic disorder. It is therefore important to understand their longer-term clinical and functional outcomes, particularly given the high prevalence of comorbid mental disorders in this population at baseline.

AIMS

This study investigated the prevalence of non-psychotic disorders in the UHR population at entry and long-term follow-up and their association with functional outcomes. Persistence of UHR status was also investigated.

STUDY DESIGN

The sample comprised 102 UHR young people from the Personal Assessment and Crisis Evaluation (PACE) Clinic who had not transitioned to psychosis by long-term follow-up (mean = 8.8 years, range = 6.8-12.1 years since baseline).

RESULTS

Eighty-eight percent of participants at baseline were diagnosed with at least one mental disorder, the majority of which were mood disorders (78%), anxiety disorders (35%), and substance use disorders (SUDs) (18%). This pattern of disorder prevalence continued at follow-up, though prevalence was reduced, with 52% not meeting criteria for current non-psychotic mental disorder. However, 35% of participants developed a new non-psychotic mental disorder by follow-up. Presence of a continuous non-psychotic mental disorder was associated with poorer functional outcomes at follow-up. 28% of participants still met UHR criteria at follow-up.

CONCLUSIONS

The study adds to the evidence base that a substantial proportion of UHR individuals who do not transition to psychosis experience persistent attenuated psychotic symptoms and persistent and incident non-psychotic disorders over the long term. Long-term treatment and re-entry into services is indicated.

The influence of complex psychiatric comorbidities on treatment for clinical high-risk for psychosis: A preliminary study

AIM

Despite increasingly refined tools for identifying individuals at clinical high-risk for psychosis (CHR-P), less is known about the effectiveness of CHR-P interventions. The significant clinical heterogeneity among CHR-P individuals suggests that interventions may need to be personalized during this emerging illness phase. We examined longitudinal trajectories within-persons during treatment to investigate whether baseline factors predict symptomatic and functional outcomes.

METHOD

A total of 36 CHR-P individuals were rated on attenuated positive symptoms and functioning at baseline and each week during CHR-P step-based treatment.

RESULTS

Linear mixed-effects models revealed that attenuated positive symptoms decreased during the study period, while functioning did not significantly change. When examining baseline predictors, a significant group-by-time interaction emerged whereby CHR-P individuals with more psychiatric comorbidities at baseline (indicating greater clinical complexity) improved in functioning during the study period relative to CHR-P individuals with fewer comorbidities.

CONCLUSION

Individual differences in clinical complexity may predict functional response during the early phases of CHR-P treatment.

Conceptualization and characterization of "primary" and "secondary" cognitive impairment in schizophrenia

Cognitive impairment represents one of the core features of schizophrenia, involves both neurocognition and social cognition domains, and has a significant negative impact on real-world functioning. The present review provides a framework for the conceptualization and characterization of "primary" and "secondary" cognitive impairment in schizophrenia. In this conceptualization, primary cognitive impairment can be defined as a consequence of the neurobiological alterations that underlie psychopathological manifestations of the disorder, while secondary cognitive impairment can be defined as the results of a source issue that has a negative impact on cognitive performance. Sources of secondary cognitive impairment are frequent in people with schizophrenia and include several different factors, such as positive and negative symptoms, depressive symptoms, autistic symptoms, pharmacotherapy, substance abuse, metabolic syndrome, social deprivation, and sleep disorders. It can be hypothesized that secondary cognitive impairment may be improved by effectively resolving the source issue, while primary cognitive impairment may benefit from dedicated treatment. Further research is required to confirm this hypothesis, to better characterize the distinction between primary and secondary cognitive impairment in a clinical and in a neurobiological perspective, and to evaluate the impact of systematically assessing and treating secondary cognitive impairment.

Time Trends in Adolescent Diagnoses of Major Depressive Disorder and Co-occurring Psychiatric Conditions in Electronic Health Records

Major depressive disorder (MDD) is highly prevalent in youth and generally characterized by psychiatric comorbidities. Secular trends in co-occurring diagnoses remain unclear, especially in healthcare settings. Using large-scale electronic health records data from a major U.S. healthcare system, we examined the prevalence of MDD diagnoses and co-occurring psychiatric conditions during adolescence (12-18 years; N = 133,753) across four generations (birth years spanning 1985 to 2002) and by sex. Then using a phenome-wide association analysis, we explored which of 67 psychiatric conditions were associated with adolescent MDD diagnosis in earlier versus recent generations. Adolescent MDD diagnosis prevalence increased (8.9 to 11.4%) over time. Over 60% with an MDD diagnosis had co-occurring psychiatric diagnoses, especially neurodevelopmental and anxiety disorders. Co-occurring diagnoses generally increased over time, especially for anxiety disorders (14 to 50%) and suicidal behaviors (6 to 23%), across both sexes. Eight comorbidities interacted with generation, showing stronger associations with MDD diagnosis in earlier (e.g., conduct disorder) versus more recent (e.g., suicidal ideation and behaviors) generations. The findings underscore the importance of assessing psychiatric complexity in adolescents diagnosed with MDD, applying transdiagnostic approaches to address co-occurring presentations, and further investigating potential causes for generational increases.

Psychological and social difficulties in young non-help-seeking adolescents at risk for psychosis: insights from a large cohort study

Background

This study used data from the Norwegian Mother, Father, and Child Cohort Study (MoBa), and explored the psychological and social challenges of 14-year-olds who report psychotic symptoms. Research on help-seeking youths indicates comorbid symptoms of depression, anxiety, and social deterioration, but less is known about non-help-seeking individuals who may not use healthcare services, possibly skewing comorbidity profiles. Also, findings suggest that adolescents manifesting psychotic symptoms refrain from pursuing help. This gap underscores the necessity of studying non-help-seeking adolescents to better understand their needs and the risks they face without intervention.

Methods

We analyzed responses from adolescents who completed the 14-year questionnaire in MoBa (N = 127), identifying those as at risk by their high scores on psychosis-risk items, within the top 0.4% (N = 58). Comparative analyses were conducted against matched controls to assess differences in psychological and social functioning (N = 69).

Results

Results indicated that the at-risk adolescents experience significantly more depression and anxiety and have lower self-esteem and poorer social functioning than controls. Social functioning parameters, including leisure activities, social competence, quality of parental relationship, and sense of school belonging, were significantly worse than those observed in controls. The results indicate a pronounced vulnerability among non-help-seeking adolescents at-risk, similar to issues seen in help-seeking youths.

Conclusion

These findings highlight the importance of early identification and intervention strategies that reach beyond traditional clinical settings, suggesting the efficacy of population or community-based screenings to prevent long-term adverse outcomes. The study proposes a broader understanding of psychosis risk, stressing the importance of inclusive approaches to support at-risk adolescents effectively.

Pseudoneurotic Symptoms in the Schizophrenia Spectrum: A Longitudinal Study of Their Relation to Psychopathology and Clinical Outcomes

BACKGROUND AND HYPOTHESIS

Nonpsychotic symptoms (depression, anxiety, obsessions, etc.) are frequent in schizophrenia-spectrum disorders and are usually conceptualized as comorbidity or transdiagnostic symptoms. However, in twentieth century foundational psychopathological literature, many nonpsychotic symptoms with specific phenomenology (here termed pseudoneurotic symptoms) were considered relatively typical of schizophrenia. In this prospective study, we investigated potential associations of pseudoneurotic symptoms with diagnostic status, functional outcome as well as psychopathological dimensions of schizophrenia.

STUDY DESIGN

First-admitted patients (N = 121) diagnosed with non-affective psychosis, schizotypal disorder, or other mental illness were examined at initial hospitalization and 5 years later with a comprehensive assessment of psychopathology. Informed by the literature, we constructed scales targeting pseudoneurotic symptoms and other, more general, nonpsychotic symptoms.

STUDY RESULTS

Pseudoneurotic symptoms aggregated in schizophrenia-spectrum groups compared to other mental illnesses and occurred at similar levels at baseline and follow-up. They longitudinally predicted poorer social and occupational functioning in schizophrenia-spectrum patients over a 5-year-period but not transition to schizophrenia-spectrum disorders from other mental illnesses. Finally, the level of pseudoneurotic symptoms correlated with disorder of basic self at both assessments and with positive and negative symptoms at follow-up. The scale targeting general nonpsychotic symptoms did not show this pattern of associations.

CONCLUSIONS

The study supports that a group of nonpsychotic symptoms, ie, pseudoneurotic symptoms, are associated with schizophrenia-spectrum disorders and linked with temporally stable psychopathology, particularly disorder of the basic self. Their prospective association with social and occupational functioning needs replication.

A mixed-methods study to evaluate the feasibility and preliminary efficacy of delivering the optimal health program (OHP) for youth at clinical high risk (CHR) for psychosis: A study protocol

Individuals with clinical high risk (CHR) for psychosis experience significant distress, impaired general functioning and a high lifetime risk of self-harm and attempted suicide. The CHR period is an important phase in an individual's mental health where appropriate interventions may reduce the risk of progression to several negative outcomes, including the development of schizophrenia. Given that up to 80% of individuals with CHR have another diagnosable mental illness and almost half experience poor psychosocial functioning, developing interventions that address psychosocial functioning in young people with CHR is of great importance. This mixed-methods study aims to employ qualitative and quantitative methods to adapt an evidence-based comprehensive psychosocial and mental health self-efficacy program, the Optimal Health Program (OHP), and evaluate the feasibility, acceptability and preliminary clinical efficacy in young people with CHR. We aim to recruit 30 CHR participants (age 16-29 years) in a single-arm 12-week exploratory clinical trial. Feasibility metrics will include recruitment, retention, and data completion rates. Acceptability will be informed by the Client Satisfaction Questionnaire. Clinical assessments (psychosis spectrum symptoms, depression, and anxiety), functional measures, and cognitive outcomes will be completed at study entry and repeated post-intervention at 12-weeks. We will run pre-post test data analysis to examine changes following engagement in the OHP intervention. Qualitative interviews will be conducted post-intervention to further evaluate the acceptability of the intervention and the trial design, and will be analyzed using thematic analysis. OHP may enhance the long-term mental health, well-being and functioning of CHR youth. However, the intervention must first be adapted to a CHR population; then, the feasibility and preliminary efficacy of delivering an intervention tailored around the varied needs of the CHR group must be established before a larger-scale appropriately powered study is pursued. Trial registration: The trial is registered with ClinicalTrials.gov NCT05757128.

Anhedonia reflects an encoding deficit for pleasant stimuli in schizophrenia: Evidence from the emotion-induced memory trade-off eye-tracking paradigm

OBJECTIVE

The present study explored the hypothesis that anhedonia reflects an emotional memory impairment for pleasant stimuli, rather than diminished hedonic capacity in individuals with schizophrenia (SZ).

METHOD

Participants included 30 SZ and 30 healthy controls (HCs) subjects who completed an eye-tracking emotion-induced memory trade-off task where contextually relevant pleasant, unpleasant, or neutral items were inserted into the foreground of neutral background scenes. Passive viewing and poststimulus elaboration blocks were administered to assess differential encoding mechanisms, and immediate and 1-week recognition testing phases were completed to assess the effects of delay interval. Participants also made self-reports of positive emotion, negative emotion, and arousal in response to the stimuli.

RESULTS

Results indicated that SZ experienced stimuli similarly to HC. Both groups demonstrated the typical emotion-induced memory trade-off during the passive viewing and poststimulus elaboration encoding blocks, as indicated by more hits for emotional than neutral items and fewer hits for backgrounds paired with emotional than neutral items. Eye-tracking data also indicated that both groups were more likely to fixate earlier and have longer dwell time on emotional than neutral items. At the 1-week delay, the emotion-induced memory trade-off was eliminated in both groups, and SZ showed fewer overall hits across valence conditions. Greater severity of anhedonia was specifically associated with impaired recognition for pleasant stimuli at the immediate recognition phase.

CONCLUSIONS

Findings suggest that anhedonia in SZ is associated with emotional memory impairment, particularly a deficit in encoding positive stimuli. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The lived experience of mental disorders in adolescents: a bottom-up review co-designed, co-conducted and co-written by experts by experience and academics

We provide here the first bottom-up review of the lived experience of mental disorders in adolescents co-designed, co-conducted and co-written by experts by experience and academics. We screened first-person accounts within and outside the medical field, and discussed them in collaborative workshops involving numerous experts by experience - representing different genders, ethnic and cultural backgrounds, and continents - and their family members and carers. Subsequently, the material was enriched by phenomenologically informed perspectives and shared with all collaborators. The inner subjective experience of adolescents is described for mood disorders, psychotic disorders, attention-deficit/hyperactivity disorder, autism spectrum disorders, anxiety disorders, eating disorders, externalizing disorders, and self-harm behaviors. The recollection of individuals' past histories also indexes the prodromal (often transdiagnostic) features predating the psychiatric diagnosis. The experience of adolescents with mental disorders in the wider society is described with respect to their family, their school and peers, and the social and cultural context. Furthermore, their lived experience of mental health care is described with respect to receiving a diagnosis of mental disorder, accessing mental health support, receiving psychopharmacological treatment, receiving psychotherapy, experiencing peer support and mental health activism, and achieving recovery. These findings can impact clinical practice, research, and the whole society. We hope that this co-designed, co-conducted and co-written journey can help us maintain our commitment to protecting adolescents' fragile mental health, and can help them develop into a healthy, fulfilling and contributing adult life.

Factors impacting intent to seek treatment within youth at clinical high risk for psychosis

Existing work indicates that there is unmet need for care in those at clinical high risk (CHR) for psychosis. However, research on the factors that drive treatment seeking behaviors in this population is limited. Further, it is unknown how help-seeking behavior in CHR individuals compares to those seen in mood disorders, who have a higher rate of treatment seeking behavior. Participants (n = 559) completed an assessment of their intent to seek mental health treatment, attenuated psychosis-risk symptoms, and psychiatric symptoms and diagnoses. Participants were divided into CHR (n = 91), Mood Disorders (MD) (n = 72), or Community Controls (CC) groups (n = 396), whose intent to seek treatment was compared. Associations between intent to seek treatment with past treatment, depression, anxiety, positive and negative symptoms, distress from symptoms, intelligence quotient (IQ) estimates, and insight were assessed in CHR individuals. Further, it was assessed how this differs for the MD group. The MD group reported higher intent to seek treatment than CHR individuals, which reported higher intent to seek treatment than the CC group. In those at CHR, previous treatment, greater depression and anxiety severity, and higher distress all independently predicted higher intent to seek treatment. Depression predicted intent to seek treatment in both MD and CHR individuals. Previous treatment predicted intent to seek treatment in those at CHR. Our findings suggest that depression and past treatment utilization are critical factors in increasing intent to seek treatment in those at CHR, potentially serving as important targets for engaging this population in treatment.

N2 Responses in Youths With Psychosis Risk Syndrome and Their Association With Clinical Outcomes: A Cohort Follow-Up Study Based on the Three-Stimulus Visual Oddball Paradigm

OBJECTIVE

Schizophrenia often occurs during youth, and psychosis risk syndrome occurs before the onset of psychosis. The aim of this study was to determine whether the visual event-related potential responses in youths with psychosis risk syndrome were defective in the presence of interference stimuli and associated with their clinical outcomes.

METHODS

A total of 223 participants, including 122 patients with psychosis risk syndrome, 50 patients with emotional disorders, and 51 healthy control subjects, were assessed. Baseline EEG was recorded during the three-stimulus visual oddball task. The event-related potentials induced by square pictures with different colors were measured. Almost all patients with psychosis risk syndrome were followed up for 12 months and were reclassified into three subgroups: conversion, symptomatic, and remission. The differences in baseline event-related potential responses were compared among the clinical outcome subgroups.

RESULTS

The average N2 amplitude of the psychosis risk syndrome group was significantly less negative than that in the healthy control group (d=0.53). The baseline average N2 amplitude in the conversion subgroup was significantly less negative than that in the symptomatic (d=0.58) and remission (d=0.50) subgroups and in the healthy control group (d=0.97). The average N2 amplitude did not differ significantly between the symptomatic and remission subgroups (d=0.02). However, it was significantly less negative in the symptomatic and remission subgroups than in the healthy control group (d=0.46 and d=0.38). No statistically significant results were found in the P3 response.

CONCLUSIONS

Youths with psychosis risk syndrome had significant N2 amplitude defects in attention processing with interference stimuli. N2 amplitude shows potential as a prognostic biomarker of clinical outcome in the psychosis risk syndrome.

Heterogeneity of clinical symptomatology in pediatric patients at clinical high risk for psychosis

OBJECTIVE

Widespread use of diagnostic tools like the Structured Interview for Prodromal Symptoms (SIPS) has highlighted that youth at Clinical High Risk for Psychosis (CHR-P) present with heterogeneous symptomatology. This pilot study aims to highlight the range of clinical characteristics of CHR-P youth, investigate the role of the non-positive (negative, disorganization, and general) symptoms in risk assessment, and determine if specific profiles are associated with severe symptomatology.

METHODS

38 participants aged 7-18 were administered the SIPS and designated as CHR-P. Descriptive statistics and mean difference t-tests were used to describe the range in prevalence and severity of SIPS symptoms and to identify symptoms associated with greater overall symptomatology.

RESULTS

Participants who had a greater number of positive symptoms also had significantly more negative, disorganization, and general symptoms. A number of SIPS symptoms were associated with greater number of positive symptoms.

CONCLUSION

CHR-P youth represent a heterogeneous group, presenting with a wide range in clinical presentation as reflected in both the number of SIPS symptoms and their severity. Though the severity and duration of positive SIPS symptoms determines the CHR-P classification, high ratings on several of the other SIPS negative, disorganization, and general items may be useful indicators of elevated symptomatology.

Improving depressive symptoms in patients with schizophrenia using bilateral bipolar-nonbalanced prefrontal tDCS: Results from a double-blind sham-controlled trial

BACKGROUND

Treating depressive symptoms in patients with schizophrenia is challenging. While transcranical Dicrect Current Stimulation (tDCS) improved other core symptoms of schizophrenia, conflicting results have been obtained on depressive symptoms. Thus, we aimed to expand current evidence on tDCS efficacy to improve depressive symptoms in patients with schizophrenia.

METHODS

A double-blind RCT was performed with patients randomized to 2 mA active-tDCS or sham-tDCS (15 daily sessions) with a bilateral bipolar-nonbalanced prefrontal placement (anode: left Dorsolateral prefrontal cortex; cathode: right orbitofrontal region). Clinical outcomes included variations of Calgary Depression Scale for Schizophrenia total score (CDSS) and of Depression-hopelessness and Guilty idea of reference-pathological guilt factors. Analysis of covariance was performed evaluating between-group changes over time. The presence/absence of probable clinically significant depression was determined when CDSS > 6.

RESULTS

As 50 outpatients were included (both groups, n = 25), significant improvements following active-tDCS were observed for CDSS total score (p = 0.001), Depression-hopelessness (p = 0.001) and Guilty idea of reference-pathological guilt (p = 0.03). Considering patients with CDSS>6 (n = 23), compared to sham, active-tDCS significantly improved CDSS total score (p < 0.001), Depression-hopelessness (p = 0.001) but Guilty idea of reference-pathological guilt only marginally improved (p = 0.051). Considering response rates of clinically significant depression, important reductions of CDSS score were observed (78 % of the sample scored ≤6; active-tDCS, n = 23; sham-tDCS, n = 16; p = 0.017). Early wakening item did not significantly change in any group.

LIMITATIONS

The study lacks a follow-up period and evaluation of tDCS effects on psychosocial functioning.

CONCLUSIONS

Bilateral bipolar-nonbalanced prefrontal tDCS is a successful protocol for the treatment of depressive symptoms in patients with schizophrenia.

Psychotic-like experiences and multimorbid psychopathology: The relationship between the 16-item prodromal questionnaire and DSM-IV classifications in a help-seeking population

AIM

Identifying multimorbid psychopathology is necessary to offer more adequate treatment and ultimately reduce the prevalence of persistent mental illnesses. Psychotic symptoms are increasingly seen as a transdiagnostic indicator of multimorbidity, severity and complexity of non-psychotic psychopathology. This study aims to investigate whether psychotic-like experiences and subclinical psychotic symptoms as measured by the 16-item Prodromal Questionnaire are also associated with multimorbid psychopathology.

METHODS

Participants were help-seeking individuals from outpatient mental healthcare settings and intensive home-treatment teams, aged 17-35. Assessment included the 16-item Prodromal Questionnaire to measure psychotic-like experiences, the Structured Clinical Interview for DSM-IV Axis I, and three sections of the Structured Clinical Interview for DSM-IV Axis II Disorders to determine DSM-IV-TR classifications. The final sample comprised of 160 participants who scored above a cutoff of 6 items on the 16-item Prodromal Questionnaire (HIGH-score) and 60 participants who scored below cutoff (LOW-score). A Poisson Regression was executed to determine the association between the PQ-16 and DSM-IV-TR classifications.

RESULTS

The HIGH-score group had a mean of 2.76 multimorbid disorders (range 0-7), while the LOW-score group had a mean of 1.45 disorders (range 0-3). Participants with four to seven disorders scored high on the 16-item Prodromal Questionnaire.

CONCLUSIONS

Our results suggest that psychotic-like experiences are associated with multimorbidity and severity of psychopathology. Screening for psychotic-like experiences via the PQ-16 in a help-seeking population may help prevent under-diagnosis and under-treatment of comorbid psychopathology.

Gender-affirming care in the assessment and treatment of psychosis risk: Considering minority stress in current practice and future research

INTRODUCTION

Although research has documented the marked disparities in rates of psychosis-spectrum diagnoses in various socially marginalized populations, there is limited research addressing the needs of gender expansive individuals in the context of psychosis-spectrum illnesses using a minority stress lens. As clinical high-risk for psychosis (CHR-p) assessment and treatment becomes accessible to increasingly diverse populations, there is a need for clinicians to demonstrate greater clinical competency working with individuals across diverse social backgrounds and identities.

METHODS

We examined rates of gender expansive (GE) patients seeking evaluation at an urban-based CHR-p clinic and compared the diagnostic profile of GE individuals to cisgender patients. Post-hoc analyses were conducted on clinical variables with significant differences between the cisgender and GE groups.

RESULTS

The proportion of GE patients seeking evaluation increased from 2017 (9.3%) to 2021 (16.7%). Compared to cisgender youth, GE patients had significantly higher depressive, social anxiety, borderline personality disorder symptoms, higher levels of suicidality and non-suicidal self-injurious behaviour, and lower role functioning. Gender identity was predictive of suicidality controlling for social anxiety, borderline symptoms, and role functioning.

CONCLUSIONS

We review implications for CHR-p treatment and discuss ways to integrate minority stress theory and gender-affirming practices into coordinated specialty care for CHR-p patients.

Factors Associated with Transition to Serious Mental Illness

OBJECTIVE

There is increasing interest in early intervention and detection strategies for youth at-risk of developing a serious mental illness (SMI). Little is known about early factors that may be related to the later development of a SMI; thus, the aim of this study was to determine what clinical factors might relate to the development of in this study psychosis, bipolar disorder and severe or recurrent major depression in at-risk youth.

METHOD

The sample consisted of 162 youth aged 12-26 years at different stages of risk. Thirty-one participants developed a SMI during the study. Those who made a transition were compared on a range of baseline clinical and functional measures with those who did not make the transition. A Cox regression model was used to assess the association between measures and later development of a SMI.

RESULTS

Female sex, attenuated psychotic symptoms as assessed with the Scale of Psychosis-Risk Symptoms (SOPS) and ratings on the K-10 Distress Scale, were found to be significantly associated with the later transition to mental illness. Females were 2.77 times more likely to transition compared to males. For the SOPS and K-10 scales, there is a 14% increase in the transition rate relative to a one-scale increase in SOPS and a 7% increase in the transition rate relative to a one-point increase in the K-10.

CONCLUSIONS

Results from these longitudinal data provide further insight into the specific clinical measures that may be pertinent in early detection of mental illnesses.

Demographic and clinical correlates of suicidal ideation in individuals with at-risk mental state (ARMS): A study from Pakistan

BACKGROUND

Suicide is a major public health concern and one of the leading causes of mortality worldwide. People with an at-risk-mental-state (ARMS) for psychosis are more vulnerable to psychiatric co-morbidity and suicide, however, there are limited data from low-middle-income countries. The present study aimed to identify the prevalence of depressive symptoms and suicidal ideation along with sociodemographic and clinical correlates of suicidal ideation in individuals with ARMS from Pakistan.

METHOD

Participants between the age of 16 and 35 years who met the criteria for ARMS based on the Comprehensive Assessment of At-Risk Mental State (CAARMS), were recruited from the community, general practitioner clinics and psychiatric units across Pakistan (n = 326). Montgomery and Asberg Depression Rating Scale (MADRS) and Social-Occupational-Functional-Assessment-Scale (SOFAS) were administered to participants.

RESULTS

The prevalence of depressive symptoms and suicidal thoughts in the sample at baseline were 91.1% (n = 297) and 61.0% (n = 199), respectively. There were significant mean differences between groups (mean difference [95% CI]; p-value) without suicidal ideation and with suicidal ideation on measures of MADRS (-5.47 [-7.14, -3.81]; p < .001), CAARMS non-bizarre ideas (-0.29 [-0.47, -0.11]; p = .002) and perceptual abnormalities (-0.23 [-0.41, -0.04]; p = .015).

CONCLUSION

These findings indicate that suicidal ideation and depressive symptoms are highly prevalent in individuals with ARMS in Pakistan. Given the pivotal developmental stages that ARMS presents, and the poor outcomes associated with co-morbid depression, there is an urgent need to prioritize the development of low-cost and scalable evidence-based interventions to address psychiatric comorbidity and suicidality in the ARMS population in Pakistan.

An exploratory study of psychosis risk factors in individuals who are referred but do not meet criteria for an early intervention in psychosis service

BACKGROUND

The 'at-risk mental state' (ARMS) for psychosis has been critiqued for its limited prognostic ability and identification of a limited proportion of those who will develop a first episode of psychosis (FEP). Broadening the search for high-risk groups is key to improving population-level ascertainment of psychosis risk.

AIMS

To explore risk enrichment in diagnostic, demographic and socio-functional domains among individuals referred to an early intervention in psychosis (EIP) service not meeting ARMS or FEP criteria.

METHOD

A retrospective file review of 16 years of referrals to a tertiary EIP service in Ireland was undertaken. Diagnostic outcomes from standardised assessments (Structured Clinical Interview for DSM), demographic (age, gender, family history, nationality) and socio-occupational (relationship status, living status, working status) variables were compiled for those not meeting criteria. These were compared with individuals diagnosed with an FEP in the same period.

RESULTS

From 2005 to 2021 inclusive, of 2025 index assessments, 27.6% (n = 558) did not meet either FEP or ARMS criteria, which is notably higher than the 5.4% (n = 110) meeting ARMS criteria. This group had high psychiatric morbidity, with 65.4% meeting criteria for at least one DSM Axis I disorder. Depressive, anxiety and substance use disorders predominated. Their functional markers were poor, and comparable to the FEP cohort.

CONCLUSIONS

This group is enriched for psychosis risk factors. They are a larger group than those meeting ARMS criteria, a finding that may reflect EIP service configuration. They may be an important focus for further study in the search for at-risk populations beyond the current ARMS model.

The specificity of the auditory P300 responses and its association with clinical outcomes in youth with psychosis risk syndrome

Background

Schizophrenia often occurs in youth, and psychosis risk syndrome (PRS) occurs before the onset of psychosis. Assessing the neuropsychological abnormalities of PRS individuals can help in early identification and active intervention of mental illness. Auditory P300 amplitude defect is an important manifestation of attention processing abnormality in PRS, but it is still unclear whether there are abnormalities in the attention processing of rhythmic compound tone stimuli in PRS individuals, and whether the P300 amplitude induced by these stimuli is specific to PRS individuals and related to their clinical outcomes.

Methods

In total, 226 participants, including 122 patients with PRS, 51 patients with emotional disorders (ED), and 53 healthy controls (HC) were assessed. Baseline electroencephalography was recorded during the compound tone oddball task. The event-related potentials (ERPs) induced by rhythmic compound tone stimuli of two frequencies (20-Hz, 40-Hz) were measured. Almost all patients with PRS were followed up for 12 months and reclassified into four groups: PRS-conversion, PRS-symptomatic, PRS-emotional disorder, and PRS-complete remission. The differences in baseline ERPs were compared among the clinical outcome groups.

Results

Regardless of the stimulation frequency, the average P300 amplitude were significantly higher in patients with PRS than in those with ED (p = 0.003, d = 0.48) and in HC (p = 0.002, d = 0.44) group. The average P300 amplitude of PRS-conversion group was significantly higher than that of the PRS-complete remission (p = 0.016, d = 0.72) and HC group (p = 0.001, d = 0.76), and the average P300 amplitude of PRS-symptomatic group was significantly higher than that of the HC group (p = 0.006, d = 0.48). Regardless of the groups (PRS, ED, HC) or the PRS clinical outcome groups, the average P300 amplitude induced by 20-Hz tone stimulation was significantly higher than that induced by 40-Hz stimulation (ps < 0.001, Ƞ2 = 0.074-0.082). The average reaction times of PRS was significantly faster than that of ED (p = 0.01, d = 0.38), and the average reaction times of the participants to 20-Hz target stimulation was significantly faster than that to 40-Hz target stimulation (p < 0.001, d = 0.21).

Conclusion

The auditory P300 amplitude induced by rhythmic compound tone stimuli is a specific electrophysiological manifestation of PRS, and the auditory P300 amplitude induced by compound tone stimuli shows promise as a putative prognostic biomarker for PRS clinical outcomes, including conversion to psychosis and clinical complete remission.

Clinical and Functional Outcomes of Community-Recruited Individuals at Clinical High-Risk for Psychosis: Results From the Youth Mental Health Risk and Resilience Study (YouR-Study)

Clinical high-risk for psychosis (CHR-P) individuals are typically recruited from clinical services but the clinical and functional outcomes of community-recruited CHR-P individuals remain largely unclear. The Youth Mental Health Risk and Resilience Study (YouR-Study) obtained a community sample of CHR-P individuals through an online-screening approach and followed-up these individuals for a period of up to 3 years to determine transition rates, persistence of attenuated psychotic symptoms (APS) and functional outcomes. Baseline data were obtained from n = 144 CHR-P participants, n = 51 participants who met online cutoff criteria but not CHR-P criteria (CHR-Ns), and n = 58 healthy controls. Baseline assessments included clinical measures for assessing CHR-P status, including the Comprehensive Assessment of At-Risk Mental States (CAARMS) and the Schizophrenia Proneness Instrument, Adult version (SPI-A), as well as functioning and cognitive measures. CHR-P and CHR-N groups were followed-up. Results show that 12.1% of CHR-P individuals transitioned to psychosis over 3 years, with no transitions in the CHR-N group. Nearly 60% of CHR-P individuals experienced poor functional outcome (PFO) and over 40% experienced persistent APS. A combination of CAARMS/SPI-A criteria was associated with a higher likelihood of PFO, but not with transition to psychosis nor APS persistence. However, transition risk was generally higher among those meeting both CAARMS/SPI-A criteria (64.3%) vs CAARMS (28.6%) or SPI-A (7.1%) alone. In summary, community-recruited CHR-P individuals are characterized by similar clinical characteristics and longitudinal outcomes to those recruited from clinical services, emphasizing the need to widen the scope of early detection and intervention strategies.

Cognitive predictors of transition and remission of psychosis risk syndrome in a child and adolescent sample: longitudinal findings from the CAPRIS study

Cognitive impairments are proposed as predictors in the differentiation between subjects with psychosis risk syndrome (PRS) who will develop a psychotic disorder (PRS-P) and those who will not (PRS-NP). More in-depth study of the PRS-NP group could contribute to defining the role of cognitive alterations in psychosis. This study aims to analyze cognition of children and adolescents with PRS in terms of their clinical outcome at 18-month follow-up (psychosis, remission, and non-remission) and of determinate predictors of transition to psychosis and remission of PRS. The method is two-site, naturalistic, longitudinal study design, with 98 help-seeking adolescents with PRS and 64 healthy controls (HC). PRS-P (n = 24) and PRS-NP (n = 74) participants were clinically and cognitively assessed at baseline, and when full-blown psychotic disorder had developed or at 18-month follow-up. PRS-P subjects showed lower scores at baseline in processing speed, visuospatial memory, attention, and executive function (cognitive flexibility/processing speed) compared to HC. PRS-NP subjects showed lower baseline scores in verbal working memory and verbal fluency compared to HC. This deficit is also observed in the PRS group of participants still presenting attenuated psychotic symptoms at 18-month follow-up, while PRS subjects in remission showed a similar cognitive profile to HC subjects. Baseline score on processing speed, measured with a coding task, appeared to be a predictive variable for the development of a psychotic disorder. Performance in verbal working memory was predictive of remission in the PRS-NP. Post hoc comparisons indicate the need for careful interpretation of cognitive markers as predictors of psychosis. Cognitive impairments are present in both PRS-P and PRS-NP. Those individuals who recover from PRS show baseline cognitive performance comparable to the HC group. Together with sociodemographic variables, this observation could help in the differentiation of a variety of PRS trajectories in children and adolescents.

Mapping Psychosis Risk States onto the Hierarchical Taxonomy of Psychopathology Using Hierarchical Symptom Dimensions

Clinical high risk for psychosis (CHR) is a transdiagnostic risk state. However, it is unclear how risk states such as CHR fit within broad transdiagnostic models such as the Hierarchical Taxonomy of Psychopathology (HiTOP). In this study, a hierarchical dimensional symptom structure was defined by unfolding factor analysis of self-report data from 3,460 young adults (mage=20.3). A subsample (n=436) completed clinical interviews, 85 of whom met CHR criteria. Regression models examined relationships between symptom dimensions, CHR status, and clinician-rated symptoms. CHR status was best explained by a reality distortion dimension, with contributions from internalizing dimensions. Positive and negative attenuated psychotic symptoms were best explained by multiple psychotic and nonpsychotic symptom dimensions including reality distortion, distress, fear, detachment, and mania. Attenuated psychotic symptoms are a complex presenting problem warranting comprehensive assessment. HiTOP can provide both diagnostic precision and broad transdiagnostic coverage, making it a valuable resource for use with at-risk individuals.

Childhood trauma is prevalent and associated with co-occurring depression, anxiety, mania and psychosis in young people attending Australian youth mental health services

OBJECTIVES

Childhood trauma is common and associated with mental ill health. While high rates of trauma are observed across individual disorders, there is evidence that trauma is associated with an admixture of affective, anxiety and psychotic symptoms in adults. Given that early onset of mental disorder and trauma exposure herald poor outcomes, it is important to examine trauma prevalence rates in youth mental health services and to determine whether this trauma-related clustering is present in help-seeking young people.

METHODS

We used data from the Transitions Study, a longitudinal investigation of young people attending headspace youth mental health services in Australia between January 2011 and August 2012. Participants were 775 young people aged 12-25. Childhood trauma was assessed using the Childhood Trauma Questionnaire. Multinomial regression was used to assess whether reported childhood trauma was more strongly associated with the co-occurrence of depression, anxiety, mania and psychosis symptoms than with any one in isolation.

RESULTS

Approximately 84% of participants reported some form of abuse (emotional: 68%; physical: 32%; sexual: 22%) or neglect (emotional: 65%; physical: 46%). Exposure to multiple trauma types was common. Childhood trauma was significantly associated with each symptom domain. More severe childhood trauma was more strongly associated with the co-occurrence of symptoms than with any one symptom domain in isolation, such that more severely trauma-exposed young people were more likely to experience increased symptom clustering.

CONCLUSIONS

Childhood trauma is pervasive in youth mental health services and associated with a symptom profile that cuts across traditional diagnostic boundaries.

The dynamics of social activation and suspiciousness in individuals at ultra-high risk for psychosis

INTRODUCTION

Social functioning is often impaired during the ultra-high risk (UHR) phase for psychosis, but group-level studies regarding the role of social functioning in transition to psychosis are inconsistent. Exploring the inter-individual differences which underlie the association between social functioning and psychotic symptoms in this phase could yield new insights.

OBJECTIVE

To examine the idiographic and dynamic association between social activation and suspiciousness in individuals at UHR for psychosis using time-series analysis.

METHODS

Twenty individuals at UHR for psychosis completed a diary application every evening for 90 days. Two items on social activation (quantity: 'time spent alone' and quality: 'feeling supported') and two items on suspiciousness ('feeling suspicious' and 'feeling disliked') were used. Time series (T = 90) of each individual were analyzed using vector auto regression analysis (VAR), to estimate the lagged (over 1 day) effect of social activation on suspiciousness, and vice versa, as well as their contemporaneous associations.

RESULTS

Heterogeneous person-specific associations between social activation and suspiciousness were found in terms of strength, direction and temporal aspects.

CONCLUSIONS

The association between social activation and suspiciousness differs amongst individuals who are at UHR for psychosis. These findings underline the importance of tailoring psychosocial interventions to the individual. Future studies may examine whether using results of single-subject studies in clinical practice to personalize treatment goals leads to better treatment outcomes.

The identification and management of people with an at-risk mental state (ARMS) for psychosis in primary and secondary care services: A qualitative interview study

AIMS

Early intervention in people with an at-risk mental state (ARMS) for psychosis can prevent the onset of psychosis. Clinical guidelines recommend that ARMS are referred to triage services, and then to Early Intervention (EI) teams in secondary care for assessment and treatment. However, little is known about how ARMS patients are identified and managed in UK primary and secondary care. This study explored patients' and clinicians' views of ARMS patients' care pathways.

METHODS

Eleven patients, 20 GPs, 11 clinicians from the triaging Primary Care Liaison Services (PCLS) and 10 EI clinicians were interviewed. Data were analysed thematically.

RESULTS

Most patients said their symptoms started in adolescence with depression and anxiety. Before being referred to EI teams, most patients were referred by their GP to well-being services for talking therapies, which they had not found helpful. Some GPs said secondary care's high acceptance thresholds and scarce treatment availability made them reluctant to refer to EI teams. Triage in PCLS was influenced by patients' risk of self-harm, and formulation of psychotic symptoms; only those without clear evidence of other pathology and not at high risk of self-harm were referred to EI teams, the others being referred to Recovery/Crisis services. Although patients referred to EI teams were offered an assessment, only some EI teams were commissioned to treat ARMS.

CONCLUSIONS

Individuals meeting ARMS criteria might not receive early intervention due to high treatment thresholds and limited treatment availability in secondary care, suggesting clinical guidelines are not being met for this patient group.

Quality of life and its predictors in first-episode schizophrenia and individuals at clinical high-risk for psychosis

BACKGROUND

This is a cross-sectional study comparing the degree of subjective quality of life (QOL) impairment and its predictive factors in first-episode schizophrenia (FES) and individuals at clinical high-risk (CHR) for psychosis.

METHODS

Seventy-seven FES, 59 CHR, and 64 healthy controls (HC) were included. The QOL of all participants was assessed using the World Health Organization Quality of Life (WHOQOL)-Brief Form (BREF). Psychiatric symptoms of individuals with FES were assessed with the Positive and Negative Syndrome Scale (PANSS), five factors were further identified through factor analysis; for individuals with CHR and HC, the Scale of Prodromal Symptoms (SOPS) was used.

RESULTS

The total and four sub-domain scores of the WHOQOL-BREF in the FES and CHR groups were lower than those of the HC group. The overall and psychological health scores in the CHR group were lowest. In the FES group, after applying Bonferroni's correction, there is a negative correlation between the total QOL scores and anxiety/depressive symptom scores (r = -0.34, P = 0.003). The stepwise multiple regression analysis showed that the QOL of both FES and CHR group were negatively affected by anxiety/depressive symptoms and unemployment (P < 0.05).

CONCLUSIONS

Compared with FES, CHR individuals are more dissatisfied with their QOL. Although diagnostic assessment of FES and CHR relies heavily on positive symptoms, the QOL is more affected by anxiety/depressive symptoms and social functioning.
