Relationship between social cognition and emotional markers and acoustic-verbal hallucination in youth with post-traumatic stress disorder: Protocol for a prospective, 2-year, longitudinal case-control study. PLoS One 2024; 19:e0306338. [PMID: 38954699 PMCID: PMC11218996 DOI: 10.1371/journal.pone.0306338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Accepted: 06/11/2024] [Indexed: 07/04/2024] Open
Abstract
INTRODUCTION Auditory-verbal hallucinatory experiences (AVH) have a 12% prevalence in the general pediatric population. Literature reports a higher risk of developing AVH in post-traumatic stress disorder (PTSD). The persistence of AVHs during adolescence represents a risk of evolution into psychotic disorders. Social cognition and emotional markers could be considered prodromes markers of this evolution. The objectives of this prospective observational study are to observe social cognition and emotional markers correlation with the presence and persistence of AVH over two years and with the evolution of PTSD and psychotic diagnosis. METHODS AND ANALYSIS This prospective case-control study, longitudinal over two years (with an interim reassessment at six months and one year), will include 40 participants aged 8 to 16 years old with a diagnosis of PTSD and without a diagnosis of psychosis according to the criteria of DSM-5 (K-SADS-PL). Subjects included are divided into two groups with AVH and without AVH matched by gender, age and diagnosis. The primary outcome measure will be the correlation between social cognition and emotional makers and the presence of AVH in the PTSD pediatric population without psychotic disorders. The social cognition marker is assessed with the NEPSY II test. The emotional marker is assessed with the Differential Emotion Scale IV and the Revised Beliefs About Voices Questionnaire. The secondary outcome measures are the correlation of these markers with the persistence of AVH and the evolution of the patient's initial diagnosis two years later. DISCUSSION The originality of our protocol is to explore the potential progression to psychosis from PTSD by cognitive biases. This study supports the hypothesis of connections between PTSD and AVH through sensory, emotional and cognitive biases. It proposes a continuum model from PTSD to psychotic disorder due to impaired perception like AVH. TRIAL REGISTRATION Clinical trial registration: ClinicalTrials.gov Identifier: NCT03356028.

Abstract
BACKGROUND Non-restorative sleep (NRS) is a core symptom of insomnia that has considerable consequences for daily life. However, the association between NRS and psychotic-like experiences (PLEs) remains unclear. The current study was designed to explore the relationship between NRS and PLEs as well as the mediation/moderation role of rumination and resilience among college students in China. METHODS 3060 college students were recruited from two universities in South China from September 21st to October 26th, 2022. Non-restorative Sleep Scale, 8-item Positive Subscale of the Community Assessment of Psychic Experiences, Ruminative Response Scale, and 10-item Connor-Davidson Resilience Scale were administered. Latent profile analysis and moderated mediation analysis were performed. RESULTS 11.3 % participants reported frequent PLEs in the past one month. Three profiles of rumination were identified and named as "low rumination" group (27.7 %), "medium rumination" group (55.3 %), and "high rumination" group (16.9 %). NRS directly predicted PLEs, and rumination played a significant mediation role between NRS and PLEs. Resilience significantly moderated the association between NRS and rumination as well as the association between NRS and PLEs. CONCLUSIONS NRS, rumination and resilience are important predictors to PLEs. Strategies on increasing restorative sleep, decreasing rumination, and enhancing resilience are of great significance in the prevention of PLEs.

Abstract
INTRODUCTION Children who experience persistent psychotic-like experiences (PLEs) are at a higher risk of developing psychotic disorder later in life. The developmental trajectories of PLEs are influenced by various factors. Therefore, it is important to identify early characteristics that can distinguish and predict between different developmental trajectories of PLEs. METHODS Using PLEs scores from the Adolescent Brain Cognitive Development (ABCD) data across three waves, we categorized participants into five distinct PLEs trajectories groups: persistent group (n = 47), remitting group (n = 185), increasing group (n = 117), remittent group (n = 21), and no PLEs group (n = 4,476). We utilized linear mixed-effect models and generalized linear mixed-effect models to examine the differences in baseline characteristics, including psychological and behavioral problems, suicidality, trauma experiences, developmental milestones, cognitive function, physical health, family income, family history of mental illness, and brain structureamong these PLEs trajectory groups. RESULTS We found that psychological and behavioral problems (such as DSM-oriented scales/externalizing/ADHD/social/attention/thought problems) assessed by the Child Behavior Checklist (CBCL) were associated with all PLEs groups. The persistent PLEs group had greater ADHD/social/thought problems and suicidal behavior compared to the remitting PLEs group. Comparing with the no PLEs group, poor cognitive function, abnormal brain structure (such as temporal lobe and supramarginal gyrus), more trauma experiences, and lower family income were found in only one of the PLEs groups, but not all PLEs groups. CONCLUSION The development of PLEs is accompanied by changes in many domains, implying a dynamic and complex developmental process. Given that psychological and behavioral problems can predict the emergence of PLEs at any time and can be regarded as risk factors for persistent PLEs, thereby enabling early precisely interventions, it is important to place greater emphasis on assessing psychological and behavioral problems.

Abstract
BACKGROUND Psychosis is one of the most disabling psychiatric disorders. Pediatric traumatic brain injury (pTBI) has been cited as a developmental risk factor for psychosis, however this association has never been assessed meta-analytically. METHODS A systematic review and meta-analysis of the association between pTBI and subsequent psychotic disorders/symptoms was performed. The study was pre-registered (CRD42022360772) adopting a random-effects model to estimate meta-analytic odds ratio (OR) and 95% confidence interval (CI) using the Paule-Mandel estimator. Subgroup (study location, study design, psychotic disorder v. subthreshold symptoms, assessment type, and adult v. adolescent onset) and meta-regression (quality of evidence) analyses were also performed. The robustness of findings was assessed through sensitivity analyses. The meta-analysis is available online as a computational notebook with an open dataset. RESULTS We identified 10 relevant studies and eight were included in the meta-analysis. Based on a pooled sample size of 479686, the pooled OR for the association between pTBI and psychosis outcomes was 1.80 (95% CI 1.11-2.95). There were no subgroup effects and no outliers. Both psychotic disorder and subthreshold symptoms were associated with pTBI. The overall association remained robust after removal of low-quality studies, however the OR reduced to 1.43 (95% CI 1.04-1.98). A leave-one-out sensitivity analysis showed the association was robust to removal of all but one study which changed the estimate to marginally non-significant. CONCLUSIONS We report cautious meta-analytic evidence for a positive association between pTBI and future psychosis. New evidence will be key in determining long-term reliability of this finding.

Abstract
The relationship between sleep disorder and psychotic experiences in preadolescence has not been extensively studied despite the potential for intervention. The current study addressed this relationship using the Adolescent Brain and Cognitive Development (ABCD) cohort, which provided baseline data from 11,830 10- to 11-year-old; for 4910 of these, 1-year follow-up data were also available. A set of pre-registered multi-level regression models were applied to test whether (a) sleep disorder is associated with psychotic experiences at baseline; (b) baseline sleep disorder predicts psychotic experiences at follow-up; (c) the persistence of sleep disorder predicts persistence of psychotic experiences at follow-up; d) the remission of sleep disorder predicts the remission of psychotic experiences at follow-up. After controlling for potential confounders, sleep disorder was associated with psychotic experiences cross-sectionally (OR = 1.40, 95% CI 1.20-1.63), at 1-year follow-up (OR = 1.32, 95% CI 1.11-1.57), and the persistence of sleep disorder predicted the persistence of psychotic experiences (OR = 1.72, 95% CI 1.44-2.04). However, remission of sleep problems did not predict remission of psychotic experiences (OR = 1.041, 95% CI 0.80-1.35). The results indicate that sleep disorders in preadolescence are common and associated with psychotic experiences, although the lack of co-remission raises questions about the mechanism of association. However, given these findings, and existing evidence in later adolescence and adults, further investigation of sleep as a preventative mental health intervention target in this age group is warranted.

Abstract
This study aimed to develop a new scale, the Early Psychotic Symptoms screening scale (EPSy), to assess the prodromes of psychotic symptoms in children aged 4 to 13 years. Two versions were proposed: one to assess the child's current behavior and one to assess the child's behavior when he/she was 2 years old. The second aim of this study was to investigate the presence of these symptoms at the age of 2 years and their evolution up to the child's current age. The analysis of EPSy identified three main factors, namely mistrust/paranoia, perceptual aberrations/hallucinations and disorganized symptoms. It has good psychometric properties. Data also shows that, independently of the participant's age, the total score on the 2-years-old version predicts the total score on the current-age version, and this is also the case for each individual factor. Finally, it is of clinical interest since it makes it possible to describe symptomatology both at age 2 and at the child's present age depending on the group to which the children are assigned (control children, psychotic children, non-psychotic children).

Abstract
BACKGROUND AND HYPOTHESIS In this study, we aimed to determine the prevalence of Psychotics-Like Experiences according to age group and their association with psychiatric disorders through these different age-group, as well as their impact on quality of life. STUDY DESIGN Using data from the second wave of the NESARC, a large general population study, we considered 6 mutually exclusive groups according to the age at the interview: 20-29 years; 30-39 years; 40-49 years; 50-59 years; 60-69 years; 70+ years. We determined the frequency of PLEs defined as positive, negative, depressive, mania and disorganization symptoms with reference to the PANSS, and the association between the presence of PLEs in the previous year and the presence of lifetime psychiatric disorders and quality of life across different age groups. STUDY RESULTS The prevalence of PLEs decreased across age from a 34.7 % in the 20-29 years age group, to 19.7 % in the 70+ years age group. Across all age groups, individuals who reported PLEs in the previous year had higher risk of having any psychiatric disorder, (i.e any mood disorder, any anxiety disorder any substance abuse and any personality disorder) compared to individuals not reporting PLEs. All dimensions of quality of life on the SF12 scale were negatively associated with the presence of a PLE regardless of age group. CONCLUSION We found that the frequency of PLEs decreased with age and that the presence of PLE is associated with psychiatric disorders and with impaired quality of life in all age groups.

Abstract
Background The long-standing view that auditory verbal hallucinations (AVH) or hearing voices is a sign of schizophrenia has been challenged by research demonstrating that they lie on a continuum ranging from normal to pathological experience related to distress and need for care. Hearing voices is more prevalent in adolescence than in later life, and hearing voices during adolescence indicates a risk for severe psychopathology, functional impairments, and suicide later in life. While there is increasing evidence for the efficacy of cognitive behavioral therapy for voices (CBTv) in adults with schizophrenia, research on psychological treatments for youth with distressing voices has been scarce. The aim of the current study is to examine the efficacy of CBTv, delivered using smartphone-based Ecological Momentary Assessment Intervention (EMI) in a transdiagnostic sample of youth. Methods This is a superiority randomized controlled trial comparing 8 weeks of CBTv-based EMI in addition to treatment as usual (TAU) versus TAU only. TAU covers both no treatment and any form of psychiatric/psychological treatment. In the EMI condition, participants will be prompted twice a day to complete an EMA survey, and receive one intervention proposal per assessment. One-hundred fifty-four youth aged 14–25 years with distressing voices will be recruited from psychiatric clinics, local private practices, internet forums, and advertisements in print and social media. Before and after the intervention phase, participants will undergo a 9-day EMA. Single-blinded assessments will be conducted at baseline (T0) and at 3-month (T1) and 6-month (T2) follow-up. The primary outcome is the distress dimension of the Auditory Hallucinations subscale of the Psychotic Symptom Rating Scales at T1. Secondary outcomes include perceived hostile intention, power, and dominance of voices, passive, aggressive, and assertive relating to voices, and negative core beliefs about the self. Discussion Adolescence provides a crucial window of opportunity for early intervention for hearing voices. However, youth are notoriously reluctant help-seekers. This study offers a low-intensity psychological intervention for youth with distressing voices beyond diagnostic boundaries that, using a mobile technology approach, may match the treatment preferences of the generation of “digital natives.” Trial registration German Clinical Trials Register DRKS00026243.

Abstract
Psychotic experiences (PE) are common in the general population, in particular in childhood, adolescence and young adulthood. PE have been shown to be associated with an increased risk for later psychotic disorders, mental disorders, and poorer functioning. Recent findings have highlighted the relevance of PE to many fields of healthcare, including treatment response in clinical services for anxiety & depression treatment, healthcare costs and service use. Despite PE relevance to many areas of mental health, and healthcare research, there remains a gap of information between PE researchers and experts in other fields. With this review, we aim to bridge this gap by providing a broad overview of the current state of PE research, and future directions. This narrative review aims to provide an broad overview of the literature on psychotic experiences, under the following headings: (1) Definition and Measurement of PE; (2) Risk Factors for PE; (3) PE and Health; (4) PE and Psychosocial Functioning; (5) Interventions for PE, (6) Future Directions.

Abstract
Alterations to striatal reward pathways have been identified in individuals with psychosis. They are hypothesized to be a key mechanism that generate psychotic symptoms through the production of aberrant attribution of motivational salience and are proposed to result from accumulated childhood adversity and genetic risk, making the striatal system hyper-responsive to stress. However, few studies have examined whether children with psychotic-like experiences (PLEs) also exhibit these alterations, limiting our understanding of how differences in reward processing relate to hallucinations and delusional ideation in childhood. Consequently, we examined whether PLEs and PLE-related distress were associated with reward-related activation in the nucleus accumbens (NAcc). The sample consisted of children (N = 6718) from the Adolescent Brain Cognitive Development (ABCD) study aged 9-10 years who had participated in the Monetary Incentive Delay (MID) task in functional MRI. We used robust mixed-effects linear regression models to investigate the relationship between PLEs and NAcc activation during the reward anticipation and reward outcome stages of the MID task. Analyses were adjusted for gender, household income, ethnicity, depressive symptoms, movement in the scanner, pubertal development, scanner ID, subject and family ID. There was no reliable association between PLEs and alterations to anticipation- or outcome-related striatal reward processing. We discuss the implications for developmental models of psychosis and suggest a developmental delay model of how PLEs may arise at this stage of development.

Encephale 2021; 48:546-554. [PMID: 34625214 DOI: 10.1016/j.encep.2021.06.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 05/16/2021] [Accepted: 06/04/2021] [Indexed: 11/18/2022]
Abstract
OBJECTIVES Auditory-verbal hallucinatory experiences (AVH) represent a prevalence of 12% in the general pediatric population. They are most often considered as a transient and benign developmental phenomenon, associated with mood and anxiety disorders. The persistence of AVHs for several years and into adolescence would represent a poor prognosis of progression into a psychiatric disorder, and more particularly psychotic disorder. The alteration of social and emotional cognitive markers are described as prodromal of this unfavorable progression which should be considered within the continuum between subclinical and clinical signs of the "psychosis phenotype". The objective of this study was to assess these markers in children and adolescents with AVH and their correlation with the presence and persistence of hallucinations. METHODS Multicenter prospective case-control study, longitudinal over 6months. Patients were included based on the presence of HAV on clinical examination. Forty subjects aged 8 to 16years from a clinical pediatric population were included. They were divided into two groups according to the Diagnostic Interview Schedule for Children-Child version (DISC-C): a group with AVH ("AVH+"), and a group without HAV ("AVH-"). A diagnosis of schizophrenia spectrum disorder was a non-inclusion criterion according to the criteria of DSM-5 (K-SADS-PL). This group was matched to the control group without AVH (AVH-) according to sex, age (±6months) and associated psychiatric diagnoses assessed by the MINI-Kid. The marker of social cognition was assessed with the NEPSY II test. The emotional marker was assessed with the self-questionnaires: EED IV, which highlights the emotions currently being felt by the subject, and the BAVQ-R, which categorizes the child's emotions in reaction to AVH. RESULTS No significant link was found between the social and emotional cognition markers and the presence of AVH at T0. At 6months, 50% of subjects in the AVH+ group suffered from persistent AVH and 18% progressed to a diagnosis of schizophrenia spectrum disorder. The persistence of AVH was not significantly correlated with the marker of social cognition, but it was significantly correlated with the presence of negative emotions (sadness, fear, hostility and anger) and inversely correlated with emotions of joy. CONCLUSION In this study, AVH experiences in the pediatric population are not linked to markers of social cognition, but negative emotions appear as early markers of AVH persistence. CLINICALTRIALS.

Abstract
BACKGROUND Although hallucinations have been studied in terms of prevalence and its associations with psychopathology and functional impairment, very little is known about sensory modalities other than auditory (i.e. haptic, visual and olfactory), as well the incidence of hallucinations, factors predicting incidence and subsequent course. METHODS We examined the incidence, course and risk factors of hallucinatory experiences across different modalities in two unique prospective general population cohorts in the same country using similar methodology and with three interview waves, one over the period 1996-1999 (NEMESIS) and one over the period 2007-2015 (NEMESIS-2). RESULTS In NEMESIS-2, the yearly incidence of self-reported visual hallucinations was highest (0.33%), followed by haptic hallucinations (0.31%), auditory hallucinations (0.26%) and olfactory hallucinations (0.23%). Rates in NEMESIS-1 were similar (respectively: 0.35%, 0.26%, 0.23%, 0.22%). The incidence of clinician-confirmed hallucinations was approximately 60% of the self-reported rate. The persistence rate of incident hallucinations was around 20-30%, increasing to 40-50% for prevalent hallucinations. Incident hallucinations in one modality were very strongly associated with occurrence in another modality (median OR = 59) and all modalities were strongly associated with delusional ideation (median OR = 21). Modalities were approximately equally strongly associated with the presence of any mental disorder (median OR = 4), functioning, indicators of help-seeking and established environmental risk factors for psychotic disorder. CONCLUSIONS Hallucinations across different modalities are a clinically relevant feature of non-psychotic disorders and need to be studied in relation to each other and in relation to delusional ideation, as all appear to have a common underlying mechanism.

Abstract
BACKGROUND Childhood infections are associated with adult psychosis and depression, but studies of psychotic experiences (PEs) and depressive symptoms in childhood, adolescence, and early-adulthood are scarce. Previous studies have typically examined severe infections, but studies of common infections are also scarce. METHODS Using data from the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort, we examined associations of the number of infections in childhood from age 1.5 to 7.5 years with depressive symptom scores at age 10, 13, 14, 17, 18, and 19 years, and with PEs at 12 and 18 years. We performed additional analysis using infection burden ('low' = 0-4 infections, 'medium' = 5-6, 'high' = 7-9, or 'very high' = 10-22 infections) as the exposure. RESULTS The risk set comprised 11 786 individuals with childhood infection data. Number of childhood infections was associated with depressive symptoms from age 10 (adjusted beta = 0.14; standard error (s.e.) = 0.04; p = <0.01) to 17 years (adjusted beta = 0.17; s.e. = 0.08; p = 0.04), and with PEs at age 12 (suspected/definite PEs: adjusted odds ratio (OR) = 1.18; 95% confidence interval (CI) = 1.09-1.27). These effect sizes were larger when the exposure was defined as very high infection burden (depressive symptoms age 17: adjusted beta = 0.79; s.e. = 0.29; p = 0.01; suspected/definite PEs at age 12: adjusted OR = 1.60; 95% CI = 1.25-2.05). Childhood infections were not associated with depressive/psychotic outcomes at age 18 or 19. CONCLUSIONS Common early-childhood infections are associated with depressive symptoms up to mid-adolescence and with PEs subsequently in childhood, but not with these outcomes in early-adulthood. These findings require replication including larger samples with outcomes in adulthood.

Abstract
Advanced paternal age has been consistently associated with an increased risk of schizophrenia. It is less known if such an association also exists with subclinical/attenuated forms of psychosis. Additionally, it has been suggested that it is not paternal age per se, but rather delayed fatherhood, as a marker of a genetic liability of psychosis, that is the cause of the association. The aim of the current study was to examine whether paternal age and/or delayed fatherhood (paternity age) predict self-reported positive, negative, and/or depressive dimensions of psychosis in a large sample from the general population. The sample (N = 1465) was composed of control subjects from the 6 countries participating in the European Union Gene-Environment Interaction study. The CAPE, a self-report questionnaire, was used to measure dimensions of subclinical psychosis. Paternal age at the time of respondents' birth and age of paternity were assessed by self-report. We assessed the influence of the variables of interest (paternal age or paternity age) on CAPE scores after adjusting for potential confounders (age, gender, and ethnicity). Paternal age was positively associated with the positive dimension of the CAPE. By contrast, paternity age was not associated with any of the psychosis dimensions assessed by the CAPE. Thus, our results do not support the idea that delayed fatherhood explains the association between age of paternity and psychosis risk. Furthermore, our results provide arguments for the hypothesis of an etiologic continuum of psychosis.

Abstract
OBJECTIVE Auditory verbal hallucinations (AVHs) are a common feature in youth and mostly transient. Nevertheless, while present, AVH can cause considerable distress. Children and adolescents seeking help for distressing AVH represent a heterogeneous group in terms of underlying factors, yet they consistently suffer from their AVH. Until now, a youth-specific psychotherapeutic intervention for AVH was lacking. Experts in the field of treating AVH in both adults and youngsters collaborated with service users to develop the cognitive behavioral therapy (CBT) "Stronger Than Your Voices" (STYV). We investigated feasibility and clinical outcomes of the STYV therapy. METHODS Patients were derived from children and adolescents seeking help for AVH at the UMC Utrecht outpatient clinic with an indication for STYV therapy. Therapists preferably originated from referring health care facilities and were required to have sufficient general knowledge and experience with CBT. They received a short individual training to apply STYV. After, patients and their therapists could participate this naturalistic pilot study, assessing feasibility, tolerability, and clinical change when applying the STYV therapy. RESULTS Six participants (10-16 years old), all suffering from comorbid psychopathology, provided pre and post measures, all completing STYV therapy without experiencing an aggravation of symptoms. AVH total impact decreased 40% with Cohen's d within-group effect size (1.28) also suggesting clinically meaningful change. Therapists were positive about STYV therapy and manual. CONCLUSION The STYV therapy is feasible for youth with distressing AVH. First results indicate that STYV may be clinically effective. A trial to further test effectiveness in a larger sample is needed.

Abstract
This is the first study to explore interpersonal schemata in outpatient youths (age 15-25 years) with early-stage borderline personality disorder (BPD) and auditory verbal hallucinations (AVH). It also aimed to replicate, in a transdiagnostic youth sample, the finding from studies of adults with AVH that negative beliefs about the self and others lead to negative appraisals of voices, which in turn elicits depression. The following 3 groups were compared: youth with BPD+AVH (n = 23), youth with schizophrenia spectrum disorder (SZ) with AVH (SZ+AVH, n = 20), and youths with BPD who did not experience AVH (BPD no AVH, n = 23). The BPD+AVH group reported more negative and fewer positive self schemata than the SZ+AVH group. They also saw themselves as being more socially inferior to others than did the SZ+AVH group, but they did not differ in appraisals of self or others, compared with the BPD no AVH group. In youths with AVH (BPD+AVH, SZ+AVH combined), the indirect effect of beliefs about self or others, via negative appraisals of voices on depression, was not significant. Instead, a significant indirect effect of negative appraisals of voices on depression, via negative beliefs about self, was found. The experience of AVH during adolescence and young adulthood, when the identity is still being formed, might have a more profound effect on the developing self than during later adulthood, when the self is more stable and resilient. Negative self-appraisals might constitute a treatment target for early intervention for youths with distressing voices, including those with BPD.

Abstract
OBJECTIVE Subthreshold perceptual abnormalities are commonly used to identify individuals at clinical high risk (CHR) for developing a psychotic disorder. Predictive validity for modality-specific perceptual abnormality severity on psychosis risk is unknown. METHODS We examined prospectively collected data from 164 individuals age 12-35 meeting criteria for CHR followed for 6-24 months or until conversion to psychosis. Using intake interview notes, baseline perceptual abnormality scores were split into auditory, visual, somatic/tactile, and olfactory/gustatory components, and auditory scores were further split into those for verbal vs non-verbal content. Relationships between perceptual abnormality characteristics and conversion were assessed with Cox proportional hazards regression and logistic regression. RESULTS Unusual thought content and paranoia were predictive of conversion, but no modality-specific perceptual abnormality score predicted conversion status or days to conversion. However, when auditory perceptual abnormalities were further categorized as verbal vs non-verbal, the severity of verbal experiences was predictive of conversion to psychosis (P = 0.007). CONCLUSIONS Perceptual abnormality scores failed to meaningfully predict conversion to psychosis in either direction in this CHR sample. However, verbal auditory experiences may identify a group of CHR individuals at elevated risk of conversion. Further exploration of the relationship between phenomenological aspects of perceptual abnormalities and conversion risk is warranted.

Abstract
BACKGROUND Subclinical psychotic experiences (PLEs) are among the frequently reported mental health problems in children/adolescents. PLEs identified in cross sectional studies of children/adolescents are associated with current and future mental health problems. These associations are stronger for PLEs that persist over time. Hence, it could be useful to examine which children/adolescents with PLEs at a first assessment (baseline) are more likely to have PLEs at subsequent assessments. METHODS We conducted a scoping review of studies that examined whether characteristics of children/adolescents (≤18 years) with PLEs at baseline predict whether PLEs are likely to be persistent or remittent at subsequent assessments. We included studies published between January 2002 and December 2017, conducted on general child/adolescent populations of ≥300 individuals, that provided data on PLEs for at least 2 time points, had available follow-up data for ≥50% of those assessed for PLEs at baseline and targeted for follow-up examination, and reported the differences between individuals with PLEs that persisted or remitted during the study period. RESULTS Six studies met our criteria. Each of them investigated a wide range of baseline characteristics but no predictor of persistence was replicated. CONCLUSIONS Our knowledge about which children/adolescents with PLEs at an initial assessment are likely to have persistent PLEs at subsequent assessments is sparse. A handful of predictors of persistent PLEs have been investigated so far, and none replicated. A better understanding of these predictors would be an important complement to investigations examining the evolution of PLEs and of mental health problems in children/adolescents.

Abstract
OBJECTIVE To compare the prevalence and risk factors associated with psychotic-like experiences (PLE) in offspring of parents with bipolar disorder (BP) and offspring of community control parents. METHOD Delusional and hallucinatory subclinical psychotic experiences were evaluated at intake and longitudinally in a cohort study of 390 offspring of BP parents and 247 offspring of control parents; all offspring were between 6 and 18 years of age. The sample was followed up every 2.5 years on average for 8.3 years. Of the sample, 91.7% completed at least one follow-up. Risk factors at intake and at each assessment until the onset of PLE were analyzed using survival models. RESULTS In all, 95 offspring (14.9%) reported PLE at some point of the study, 16.9% of BP parents and 11.7% of controls, without statistically significant differences. Psychotic disorders were less frequent, with 16 (2.5%) in both groups. During follow-up, three variables remained as the most significant associated with PLE in the multivariate models: (1) presence of any psychiatric disorder (hazard ratio [HR] = 3.1; p = .01); (2) low psychosocial functioning (HR = 2.94; p < .0001); and (3) current or past history of physical or sexual abuse (HR = 1.85; p = .04). There were no effects of any subtype of BP, IQ, history of medical illnesses, exposure to medications, or perinatal complications. CONCLUSION In line with previous studies, PLE in our sample were relatively common, and were associated with higher morbidity during the follow-up. Contrary to the literature, neither family risk for bipolar nor early neurodevelopmental insults were associated with PLE.

The impact of age on the validity of psychosis-risk screening in a sample of help-seeking youth. Psychiatry Res 2019; 274:30-35. [PMID: 30780059 PMCID: PMC7513881 DOI: 10.1016/j.psychres.2019.02.020] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Revised: 02/08/2019] [Accepted: 02/08/2019] [Indexed: 12/18/2022]
Abstract
Self-report screening instruments offer promise in furthering early identification of at-risk youth, yet current efforts are limited by false positive rates. Identifying moderators of accuracy is a potential step towards improving identification and prevention efforts. We investigated the moderating effect of age on self-reported attenuated positive symptoms from the Prime Screen and clinician diagnosed clinical high-risk/early psychosis (CHR/EP) status. Participants (N = 134) were racially diverse, lower-income, help-seeking adolescents and young adults from a primarily urban community. The overall model predicting CHR/EP status was significant, with results suggesting the presence of a trending interaction between age and Prime Screen symptoms. Analyses indicated that number of items endorsed to predict CHR/EP decreased with age (youngest group [M = 12.99] cut off = 6 items; middle age group [M = 14.97] cut off = 3; oldest age group [M = 18.40] cut off = 1). Although younger participants endorsed more risk items on average, follow up analyses suggested that the Prime Screen was a more accurate predictor of clinician-diagnosed-risk among older participants relative to their younger peers. The current study builds on the literature identifying moderators of psychosis-risk screening measure accuracy, highlighting potential limitations of CHR/EP screening tools in younger populations.

Abstract
Hallucinations in children and adolescents are now known to occur on a continuum from healthy to psychopathology-related phenomena. Although hallucinations in young populations are mostly transient, they can cause substantial distress. Despite hallucinations being widely investigated, research so far has had limited implications for clinical practice. The present article has 3 main aims: (1) to review research findings since 2014 (when the last major review of the area was published); (2) to present assessment tools validated to measure hallucinations in children and adolescents; and (3) to discuss therapeutic strategies and clinical issues. We conclude by presenting a tailored care model for clinicians and outline future challenges for research.

Abstract
Studies in adolescents on ultra-high risk (UHR) and basic symptoms (BS) criteria for psychosis prediction are scarce. In Italy, early interventions in psychosis are less widespread than in other European countries. In the present study, we (1) assessed the clinical relevance of a UHR diagnosis [according to the comprehensive assessment of at-risk mental states (CAARMS) criteria] to promote the implementation of specific services for UHR adolescents into the Italian health care system; (2) described severity of positive, negative, general, and basic symptoms in UHR adolescents compared to adolescents with first-episode psychosis (FEP) and non-UHR adolescents (i.e., individuals who did not meet CAARMS criteria for UHR or FEP); and (3) investigated the predictive validity of UHR criteria in relation to BS criteria. Seventy-nine adolescents (aged 13-18 years) were assessed with the CAARMS, the positive and negative syndrome scale (PANSS), and the schizophrenia proneness instrument, child and youth version (SPI-CY). Both UHR (n = 25) and FEP (n = 11) had significantly higher PANSS subscale scores compared to non-UHR (n = 43). UHR had significantly lower PANSS-positive symptom scores than FEP, but similar global functioning and PANSS-negative symptoms and general psychopathology scores. Compared to non-UHR, both FEP and UHR had more severe thought and perception BS disturbances, and significantly more often met BS criteria. After 12 months, 2 of 20 (10%) UHR had transitioned to psychosis. They also met both BS criteria. Given the uncertain outcome of UHR adolescents, future research is needed to determine whether the combined assessment of BS with UHR symptoms can improve the accuracy of psychosis prediction in adolescence.

Abstract
BACKGROUND Auditory Hallucinations (AH) are nowadays regarded as symptoms following a continuum; from a (transient) phenomenon in healthy individuals on one end to a symptom of (psychiatric) illnesses at the other. An accumulating number of epidemiological studies focused on the prevalence of AH in the general population, but results vary widely. The current meta-analysis aims to synthesize existing evidence on lifetime prevalence of AH across the lifespan. METHODS We conducted a quantitative review and meta-analysis according to PRISMA guidelines. Studies were combined to calculate a mean lifetime general population AH prevalence rate. Moreover, prevalences were calculated for four age groups: children (5-12 years), adolescents (13-17 years), adults (18-60 years) and elderly (⩾60 years). RESULTS We retrieved 25 study samples including 84 711 participants. Mean lifetime prevalence rate of AH was 9.6% (95% CI 6.7-13.6%). The mean lifetime prevalence was similar in children (12.7%) and adolescents (12.4%), but these two groups differed significantly from the adults (5.8%) and the elderly (4.5%). Significant heterogeneity indicated that there is still dispersion in true prevalence rates between studies, even within the different age categories. CONCLUSIONS Current meta-analysis shows that AH are quite common (up to one in ten individuals) in the general population during lifetime, with children and adolescents reporting these experiences significantly more often compared with adults and elderly. Large follow-up studies on the longitudinal course of AH are needed to reveal associated risk and resilience factors.

Abstract
BACKGROUND The prevalence and clinical significance of hallucinatory experiences among children below 7 years of age remain unknown. We aimed to determine the independent influences of sensory deficits, the presence of an imaginary companion and metacognition on hallucinatory experiences. We assumed that hallucinatory experiences were associated with (a) sensory deficits, (b) the presence of an imaginary companion (IC) and (c) metacognition defaults (i.e. first- and second-order theory of mind default). METHODS All children in the third year of preschool from a region of Northern France underwent medical screening. We compared the prevalence rates of visual, auditory and audio-visual hallucinatory experiences based on (a) the presence of visual or auditory deficits, (b) the actual presence of an IC and (c) metacognition. The analyses were adjusted for age. RESULTS A total of 1,087 children aged between 5 and 7 years were included. The prevalence rates of auditory, visual and audio-visual hallucinatory experiences were 15.8%, 12.5% and 5.8%, respectively. The prevalences of different types of hallucinatory experiences were not significantly different according to sensory deficit. The prevalences of all types of hallucinatory experiences were significantly higher among children with an IC and among children with metacognition defaults. CONCLUSIONS The association between hallucinatory experiences and sensory deficits might concern only long-lasting deficits. The association with the presence of an IC confirms experimental findings of the likelihood of perceiving words among meaningless auditory stimuli. Relations between hallucinatory experiences and theory of mind need to be addressed in longitudinal studies.

Abstract
OBJECTIVES Women have higher rates of auditory verbal hallucinations (AVH) than men; however, less is known about sex differences in the prevalence of AVH in early, middle and late adolescence. We sought to elucidate the differences in the prevalence of AVH and to examine the degree to which these differences could be explained by differences in levels of depressive symptoms. DESIGN We used a cross-sectional design and a self-reported questionnaire. SETTING Participants were recruited from public junior and senior high schools in Tsu, Mie Prefecture and Kochi Prefecture, Japan. PARTICIPANTS In total, 19 436 students were contacted and 18 250 participated. Responses from 17 451 students with no missing data were analysed (aged 12-18 years, Mage=15.2 years (SD=1.7), 50.6% girls). MEASURES AVH were assessed through one of four items adopted from the schizophrenia section of the Japanese version of the Diagnostic Interview Schedule for Children. Depressive symptoms were assessed using the 12-item General Health Questionnaire. RESULTS The prevalence of AVH was 7.0% among early adolescents (aged 12-13 years), 6.2% among middle adolescents (aged 14-15 years) and 4.8% among late adolescents (aged 16-18 years). Being female was significantly associated with a higher prevalence of AVH through adolescence (OR=1.71, 95% CI 1.31 to 2.23 in early adolescence; OR=1.42, 95% CI 1.14 to 1.76 in middle adolescence; OR=1.52, 95% CI 1.23 to 1.87 in late adolescence); however, these differences became non-significant after adjusting for depressive symptoms (OR=1.21, 95% CI 0.92 to 1.60; OR=1.00, 95% CI 0.80 to 1.25; OR=1.16, 95% CI 0.93 to 1.44, respectively). CONCLUSIONS Sex differences in auditory hallucinations are seen in both adult and youth populations. The higher rates of auditory verbal hallucinations seen in girls may be secondary to the differences in the rate of depressive symptoms.

Abstract
BACKGROUND Auditory Verbal Hallucinations (AVH) in children and adolescents are a relatively common and mostly transient feature in community samples. However, it should not be regarded as a merely benign phenomenon, as childhood AVH are associated with psychopathology. Little is known about the clinical group of children seeking help for AVH. This brings uncertainty on how to assess and treat these children. METHODS This study describes the characteristics of 95 help-seeking children (aged 6 to 18years) with AVH attending an outpatient clinic specifically dedicated to help youth with this complaint. We aim to provide pointers regarding diagnostic assessment and interventions. RESULTS Children seeking help for AVH suffered from a diversity of co morbid psychiatric diagnoses and consistently experienced high stress from AVH. When the DSM-IV-TR criteria for psychotic disorder NOS were used, all 95 children obtained this diagnosis. However, when a psychotic disorder was defined using the A-criterion of schizophrenia, only a minority of 11 cases (11.6%) was diagnosed as having a psychotic disorder. All children were in need of psycho-education and coping strategies and only the minority (11.6%) fulfilling criteria for a more narrowly defined psychotic disorder was prescribed antipsychotic medication. CONCLUSIONS Children seeking help for AVH form a heterogeneous group with high stress and reduced functioning. Even though only a minority (11.6%) suffers from a psychotic disorder, all children warrant clinical care due to their burden and multi morbid psychopathology.

Abstract
BACKGROUND The 22q11.2 deletion syndrome (22q11DS) is one of the highest known risk factors for schizophrenia. Thus, the detection of 22q11DS patients at particularly high risk of psychosis is important, yet studies on the clinical significance of the widely used ultra-high risk (UHR) criteria in 22q11DS are inconclusive. Since age was reported to moderate clinical significance of UHR symptoms in community samples, we explored whether age at presentation of UHR symptoms and criteria may explain part of this heterogeneity. METHODS 111 patients with 22q11DS (8-30 years; 15.7±4.7) were assessed for UHR symptoms/criteria. Information on diagnoses, psychosocial functioning, and IQ were collected. RESULTS Any UHR symptom was reported by 38.7%, any UHR criterion by 27%. No significant influence of age on the prevalence of UHR symptoms or criteria was detected. Moreover, age did not significantly modulate the association between UHR symptoms and functioning. However, significant interaction terms suggested that younger age groups were more likely to meet UHR criteria in the presence of UHR symptoms compared to the adult group. DISCUSSION Compared to the general population, prevalence of UHR symptoms and criteria was 3.8-fold and 20.8-fold in our 22q11DS sample. Contrary to the general population, age only modulated the prevalence of UHR criteria among those with UHR symptoms, but not their prevalence per se or their clinical significance. This suggests that UHR symptoms might develop as a trait factor in terms of a genetically driven schizotypal disposition in 22q11DS, thus necessitating future studies on psychosis-risk indicators in this genetic high-risk group.

Abstract
Children's hallucinations pose the dual challenge of diagnosing a possible medical emergency and a possible psychiatric disorder. PURPOSE The main objective was to analyze the causes of such hallucinations in children presenting to a pediatric emergency department. MATERIAL AND METHODS We conducted a single-center, observational, retrospective study including all children aged less than 15 years experiencing hallucinations and admitted to our tertiary level pediatric emergency department between 1 January 2007 and 31 December 2015. The data collected were demographic; medical: previous medical or psychiatric history, current medications, associated clinical or psychiatric symptoms, type and character of hallucinations, length and recurrence of hallucinatory phenomena; and other biological, radiological and neurological explorations. RESULTS Sixty-eight patients were included (29 boys). The mean age was 9.1±3 years (range, 2-14 years and 10 months; median, 9.2 years). Admissions were seasonal with a bimodal distribution (a peak during springtime and another one during fall). Hallucinations were mainly visual (90%), acute (77%) and complex (63%). Visual hallucinations were associated with other types of hallucinations: auditory (n=17), somatosensory (n=7). Fifteen children had a psychiatric history and had already experienced hallucinatory phenomena (93%). Among 47 patients (69%), these hallucinations were associated with other symptoms: agitation (41%), headaches (28%), hyperthermia (21%) and negative symptoms of the schizophrenia spectrum (15%). On admission, 20 patients (29%) had one or more treatments under way (34 drugs, 41% known for hallucinogenic adverse effects). Neurological explorations were undertaken in half of the cases. Toxicological analysis prescribed in 19 children was positive in five cases (26%). Fifty-three percent of patients were hospitalized and 51 children received a specialized follow-up (by a neurologist and/or a psychiatrist). A nonpsychiatric origin of these hallucinations was diagnosed in 29 patients (43%): neurological causes (n=10), infectious diseases (n=10), intoxications (n=5) and a medication side effect (n=4). CONCLUSION Hallucinations with a suspected underlying psychiatric cause differed on several factors: chronic duration (p=0.02), an onset after 10 years of age (p=0.004), previous identical episodes (p=0.014) and a parental psychiatric history (p=0.036), auditory hallucinations (p=0.0009), absence of fever (p=0.005), headaches (p=0.036) and the presence of negative symptoms of the schizophrenic spectrum (p=0.02).

Goghari VM, Harrow M. Twenty year multi-follow-up of different types of hallucinations in schizophrenia, schizoaffective disorder, bipolar disorder, and depression. Schizophr Res 2016; 176:371-377. [PMID: 27349816 DOI: 10.1016/j.schres.2016.06.027] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2016] [Revised: 06/18/2016] [Accepted: 06/21/2016] [Indexed: 11/15/2022]
Abstract
Hallucinations are a salient feature of both psychotic and mood disorders. Currently there is a call for more research on the phenomenology of different forms of hallucinations, in a broader array of disorders, to further both theoretical knowledge and clinical utility. We investigated auditory, visual, and olfactory hallucinations at index hospitalization and auditory and visual hallucinations prospectively for 20years in 150 young patients, namely 51 schizophrenia, 25 schizoaffective, 28 bipolar, and 79 unipolar depression. For the index hospitalization, the data showed schizophrenia and schizoaffective patients had a greater rate of auditory and visual hallucinations than bipolar and depression patients. However, over the longitudinal trajectory of their illness, a greater percentage of schizophrenia patients had auditory and visual hallucinations than schizoaffective patients, as well as bipolar and depression patients. Also, in contrast to the initial period, schizoaffective patients did not differentiate themselves over the follow-up period from bipolar patients. Bipolar and depression patients did not significantly differ at index hospitalization or at follow-up. We found visual hallucinations differentiated the groups to a greater degree over the 20year course than did auditory hallucinations. These findings suggest the longitudinal course is more important for differentiating schizophrenia and schizoaffective disorder, whereas the initial years may be more useful to differentiate schizoaffective disorder from bipolar disorder. Furthermore, we found that the early presence of auditory hallucinations was associated with a reduced likelihood for a future period of recovery. No olfactory hallucinations were present at the index hospitalization in any patients. Over the course of 20years, a minority of schizophrenia patients presented with olfactory hallucinations, and very few schizoaffective and bipolar patients presented with olfactory hallucinations. This study underscores the importance of the longitudinal course of symptoms to understand the relationship between related disorders and recovery.

Abstract
BACKGROUND Auditory verbal hallucinations (AVH) are common during development and may arise due to dysregulation in top-down processing of sensory input. This study was designed to examine the frequency and correlates of speech illusions measured using the White Noise (WN) task in children from the general population. Associations between speech illusions and putative risk factors for psychotic disorder and negative affect were examined. METHOD A total of 1486 children aged 11-12 years of the Copenhagen Child Cohort 2000 were examined with the WN task. Psychotic experiences and negative affect were determined using the Kiddie-SADS-PL. Register data described family history of mental disorders. Exaggerated Theory of Mind functioning (hyper-ToM) was measured by the ToM Storybook Frederik. RESULTS A total of 145 (10%) children experienced speech illusions (hearing speech in the absence of speech stimuli), of which 102 (70%) experienced illusions perceived by the child as positive or negative (affectively salient). Experiencing hallucinations during the last month was associated with affectively salient speech illusions in the WN task [general cognitive ability: adjusted odds ratio (aOR) 2.01, 95% confidence interval (CI) 1.03-3.93]. Negative affect, both last month and lifetime, was also associated with affectively salient speech illusions (aOR 2.01, 95% CI 1.05-3.83 and aOR 1.79, 95% CI 1.11-2.89, respectively). Speech illusions were not associated with delusions, hyper-ToM or family history of mental disorders. CONCLUSIONS Speech illusions were elicited in typically developing children in a WN-test paradigm, and point to an affective pathway to AVH mediated by dysregulation in top-down processing of sensory input.

Abstract
OBJECTIVE Childhood auditory vocal hallucinations (AVH) are mostly transient but may predict clinical outcomes. Little is known about their course over time and associations with risk factors, and how this may inform early intervention. Our objective was to assess the 11-year course of AVH, associated psychopathology and risk factors. METHOD A 5-year (T1) and 11-year (T2) follow-up of a baseline case-control sample (n = 694, of whom 347 with AVH). At T2, online assessment of AVH, other psychotic experiences, psychopathology, trauma and cannabis use was completed by 293 adolescents aged 18-19 years. RESULTS The AVH 6-year (T1-T2) persistence rate was 18.2%, and the AVH 11-year (T0-T2) persistence rate was 6.2%. AVH at T2 were associated with higher levels of T2 other psychotic experiences, T2 psychopathology and T2 traumatic events, but not with T2 stress or T2 cannabis use. Persistence of AVH (i.e. AVH reported two or three times from T0) was associated with T2 traumatic events and higher risk for post-traumatic stress disorder. CONCLUSION Auditory vocal hallucinations in early childhood are mostly transitory. AVH in adolescence, especially when persistent, are associated with affective symptoms and environmental risk, particularly traumatic events.

Abstract
BACKGROUND Stimulants, such as methylphenidate, are among the most commonly used medications in children and adolescents. Psychotic symptoms have been reported as rare adverse reactions to stimulants but have not been systematically inquired about in most previous studies. Family history of mental illness may increase the vulnerability to drug-induced psychotic symptoms. We examined the association between stimulant use and psychotic symptoms in sons and daughters of parents with major mood and psychotic disorders. METHODS We assessed psychotic symptoms, psychotic-like experiences, and basic symptoms in 141 children and youth (mean ± SD age: 11.8 ± 4.0 years; range: 6-21 years), who had 1 or both parents with major depressive disorder, bipolar disorder, or schizophrenia, and of whom 24 (17.0%) had taken stimulant medication. RESULTS Psychotic symptoms were present in 62.5% of youth who had taken stimulants compared with 27.4% of participants who had never taken stimulants. The association between stimulant use and psychotic experiences remained significant after adjustment for potential confounders (odds ratio: 4.41; 95% confidence interval: 1.82-10.69; P = .001) and was driven by hallucinations occurring during the use of stimulant medication. A temporal relationship between use of stimulants and psychotic symptoms was supported by an association between current stimulant use and current psychotic symptoms and co-occurrence in cases that were assessed on and off stimulants. CONCLUSIONS Psychotic symptoms should be monitored during the use of stimulants in children and adolescents. Family history of mood and psychotic disorders may need to be taken into account when considering the prescription of stimulants.

Identifying children and adolescents at ultra high risk of psychosis in Italian neuropsychiatry services: a feasibility study. Eur Child Adolesc Psychiatry 2016; 25:91-106.

Abstract
The past 20 years have seen the evolution of the construct of a clinical high-risk (hereafter, HR) state for psychosis. This construct is designed to capture the pre-psychotic phase. Some aspects of this approach, such as its feasibility in children and adolescents, are still under investigation. In the present study, we address the feasibility of implementing prodrome clinics for HR individuals within the framework of Italy's national child and adolescent neuropsychiatry services and the clinical relevance of a HR diagnosis in this population. Using the Comprehensive Assessment of At-Risk Mental States (CAARMS) to identify help-seeking patients meeting at least one HR criterion at baseline (HR+), we recruited 50 subjects for a feasibility study. The results obtained show that the Italian version of the CAARMS is easily administrable, causing patients no substantial discomfort. The prevalence of HR+ in our cohort was 44 %, which increased by an additional 18 % when negative symptoms were considered as an experimental inclusion criterion (HRNeg). The HR+ subjects were significantly more impaired in their social and occupational functioning than their HR- peers (subjects not at HR). The cumulative 1-year transition risk of psychosis of the HR+ group was 26.7 %. When the HRNeg group was added, the 1-year transition risk was 17.3 %. We suggest that administration of the CAARMS to children and adolescents with putative prodromal psychosis is feasible and that this assessment can easily be integrated into existing Italian neuropsychiatry services although clinicians should interpret results with caution as results in this age group still have to be replicated.

Abstract
Early detection of psychosis is an important topic in psychiatry. Yet, there is limited information on the prevalence and clinical significance of high-risk symptoms in children and adolescents as compared to adults. We examined ultra-high-risk (UHR) symptoms and criteria in a sample of individuals aged 8-40 years from the general population of Canton Bern, Switzerland, enrolled from June 2011 to May 2014. The current presence of attenuated psychotic symptoms (APS) and brief intermittent psychotic symptoms (BLIPS) and the fulfillment of onset/worsening and frequency requirements for these symptoms in UHR criteria were assessed using the Structured Interview for Psychosis Risk Syndromes. Additionally, perceptive and non-perceptive APS were differentiated. Psychosocial functioning and current non-psychotic DSM-IV axis I disorders were also surveyed. Well-trained psychologists performed assessments. Altogether, 9.9% of subjects reported APS and none BLIPS, and 1.3% met all the UHR requirements for APS. APS were related to more current axis I disorders and impaired psychosocial functioning, indicating some clinical significance. A strong age effect was detected around age 16: compared to older individuals, 8-15-year olds reported more perceptive APS, that is, unusual perceptual experiences and attenuated hallucinations. Perceptive APS were generally less related to functional impairment, regardless of age. Conversely, non-perceptive APS were related to low functioning, although this relationship was weaker in those below age 16. Future studies should address the differential effects of perceptive and non-perceptive APS, and their interaction with age, also in terms of conversion to psychosis.

Abstract
Knowing the prevalence and characteristics of auditory verbal hallucinations (AVH) in adolescents is important for estimations of need for mental health care and assessment of psychosis risk. In this report we assess the prevalence of AVH in a population-based sample of 16-19 years old Norwegian adolescents (n = 9,646, 46.4% male) using two items assessing AVH (from the extended Launay-Slade Hallucination Scale). The prevalence of hearing a voice speaking thoughts aloud was 10.6%. The prevalence of being troubled by voices was 5.3%, showing that negative emotionality about AVH is less frequent than the experience of hearing voices. Female respondents had slightly increased risk for being troubled by voices than males (odds ratio = 1.3), while age did not modulate prevalence. This AVH prevalence is in line with earlier reports in smaller samples of adolescents and indicates that AVH are not uncommon in this period of life. Further longitudinal studies are needed to investigate the value of AVH in predicting psychiatric disorder.

Abstract
The aim of this guidance paper of the European Psychiatric Association is to provide evidence-based recommendations on the early detection of a clinical high risk (CHR) for psychosis in patients with mental problems. To this aim, we conducted a meta-analysis of studies reporting on conversion rates to psychosis in non-overlapping samples meeting any at least any one of the main CHR criteria: ultra-high risk (UHR) and/or basic symptoms criteria. Further, effects of potential moderators (different UHR criteria definitions, single UHR criteria and age) on conversion rates were examined. Conversion rates in the identified 42 samples with altogether more than 4000 CHR patients who had mainly been identified by UHR criteria and/or the basic symptom criterion 'cognitive disturbances' (COGDIS) showed considerable heterogeneity. While UHR criteria and COGDIS were related to similar conversion rates until 2-year follow-up, conversion rates of COGDIS were significantly higher thereafter. Differences in onset and frequency requirements of symptomatic UHR criteria or in their different consideration of functional decline, substance use and co-morbidity did not seem to impact on conversion rates. The 'genetic risk and functional decline' UHR criterion was rarely met and only showed an insignificant pooled sample effect. However, age significantly affected UHR conversion rates with lower rates in children and adolescents. Although more research into potential sources of heterogeneity in conversion rates is needed to facilitate improvement of CHR criteria, six evidence-based recommendations for an early detection of psychosis were developed as a basis for the EPA guidance on early intervention in CHR states.

Abstract
BACKGROUND Recent cross-sectional studies have shown psychotic experiences (PEs) are associated with suicidal ideation and behaviours. We aimed to examine associations between psychotic experiences (including persistent PE), and contemporaneous and incident non-suicidal self-injury (NSSI) and suicide attempts. METHOD Participants were from an Australian longitudinal cohort of 1896 adolescents (12-17 years). NSSI and suicide attempts were measured using the Self-Harm Behaviour Questionnaire. Items from the Diagnostic Interview Schedule for Children were used to assess psychotic experiences, and the General Health Questionnaire-12 measured psychological distress. RESULTS Adolescents both psychologically distressed and endorsing psychotic experiences had increased odds of contemporaneous and incident NSSI and attempted suicide. Psychotic experiences alone did not predict future risk. Persistent psychotic experiences were associated with increased risk of NSSI and suicide attempts. CONCLUSIONS Psychological distress with accompanying psychotic experiences and persistent psychotic experiences are important predictors of NSSI and suicide attempts. Screening these phenotypes in adolescents will assist in discerning those adolescents most at risk, providing opportunities for targeted suicide prevention strategies.

Well-conducted systematic reviews have the ability to make robust, generalizable conclusions, with good meta-analyses potentially providing the closest estimate of the true effect size. In this paper, we undertake a systematic approach to synthesising the available evidence from well-conducted systematic reviews on schizophrenia. METHOD Reviews were identified by searching Medline, EMBASE, CINAHL, Current Contents and PsycINFO. The decision to include or exclude reviews, data extraction and quality assessments were conducted in duplicate. Evidence was graded as high quality if reviews contained large samples and robust results; and as moderate quality if reviews contained imprecision, inconsistency, smaller samples or study designs that may be prone to bias. RESULTS High- and moderate-quality evidence shows that numerous psychosocial and biomedical treatments are effective. Patients have relatively poor cognitive functioning, and subtle, but diverse, structural brain alterations, altered electrophysiological functioning and sleep patterns, minor physical anomalies, neurological soft signs, and sensory alterations. There are markers of infection, inflammation or altered immunological parameters; and there is increased mortality from a range of causes. Risk for schizophrenia is increased with cannabis use, pregnancy and birth complications, prenatal exposure to Toxoplasma gondii, childhood central nervous system viral infections, childhood adversities, urbanicity and immigration (first and second generation), particularly in certain ethnic groups. Developmental motor delays and lower intelligence quotient in childhood and adolescence are apparent. CONCLUSIONS We conclude that while our knowledge of schizophrenia is very substantial, our understanding of it remains limited.

Abstract
BACKGROUND Schizophrenia has a neurodevelopmental component to its origin, and may share overlapping pathogenic mechanisms with childhood neurodevelopmental disorders (NDs). Nevertheless, longitudinal studies of psychotic outcomes among individuals with NDs are limited. We report a population-based prospective study of six common childhood NDs, subsequent neurocognitive performance and the risk of psychotic experiences (PEs) in early adolescence. METHOD PEs were assessed by semi-structured interviews at age 13 years. IQ and working memory were measured between ages 9 and 11 years. The presence of six NDs (autism spectrum, dyslexia, dyspraxia, dysgraphia, dysorthographia, dyscalculia) was determined from parent-completed questionnaires at age 9 years. Linear regression calculated the mean difference in cognitive scores between children with and without NDs. Associations between NDs and PEs were expressed as odds ratios (ORs) with 95% confidence intervals (CIs); effects of cognitive deficits were examined. Potential confounders included age, gender, father's social class, ethnicity and maternal education. RESULTS Out of 8220 children, 487 (5.9%) were reported to have NDs at age 9 years. Children with, compared with those without, NDs performed worse on all cognitive measures; the adjusted mean difference in total IQ was 6.84 (95% CI 5.00-8.69). The association between total IQ and NDs was linear (p < 0.0001). The risk of PEs was higher in those with, compared with those without, NDs; the adjusted OR for definite PEs was 1.76 (95% CI 1.11-2.79). IQ (but not working memory) deficit partly explained this association. CONCLUSIONS Higher risk of PEs in early adolescence among individuals with childhood ND is consistent with the neurodevelopmental hypothesis of schizophrenia.

Abstract
IntroductionLa prévalence des hallucinations chez les enfants et les adolescents est de 4,9 % à 9 % [1]. Il s’agit d’un symptôme polysémique dont le repérage précoce reste un enjeu majeur du fait du risque évolutif vers un trouble psychotique cependant rare.ObservationNous rapportons deux cas d’hallucinations auditives et cénesthésiques. Dans le premier cas, une adolescente de 13 ans présentait un syndrome de stress post-traumatique suite à une agression. Les hallucinations survenaient lorsqu’elle était seule dans la rue. L’approche systémique du symptôme mettait à jour un mythe familial de menace. En effet, l’agression renforçait un sentiment ancien de persécution par la société, notamment concernant ses parents handicapés par une surdité congénitale. Dans le second cas, un enfant de 9 ans présentait des hallucinations auditives se manifestant par une mélodie agréable et s’inscrivant dans un contexte de violents conflits entre sa mère et son beau-père. Contemporain d’un repli sur soi et de mouvements anxieux et tristes, ce symptôme semblait également traduire une souffrance familiale.DiscussionConcomitamment à l’amendement des hallucinations, la mise en perspective relationnelle du symptôme a permis de retrouver une vitalité du lien. En effet, par ce premier lien de vulnérabilité établi avec les soignants, les familles ont retrouvé confiance dans leur capacité à s’ouvrir au monde extérieur offrant ainsi une opportunité pour le changement.ConclusionUne vision intégrative tenant compte non seulement des avancées de l’imagerie et des nombreux modèles neurobiologiques et neurocognitifs [2,3], mais aussi du contexte relationnel du patient, semble fondamentale à la prise en charge globale des hallucinations de l’enfant et de l’adolescent.

Abstract
BACKGROUND Several studies suggest a link between early-life infection and adult schizophrenia. Cross-sectional studies have reported: (1) increased prevalence of Epstein-Barr Virus (EBV), a member of the Herpesviridae family in schizophrenia; (2) a possible role of Herpes simplex virus in cognitive dysfunction in schizophrenia and healthy controls. We report a longitudinal serological study of early-life EBV infection, childhood IQ, and subsequent risk of psychotic experiences (PE) in adolescence. METHODS Serum antibodies to EBV (anti-VCA IgG) were measured in 530 participants from the ALSPAC cohort at age 4 years. Assessments for IQ at age 9 and PE at age 13 were attended by 401 and 366 of these individuals, respectively. Logistic regression calculated odds ratio (OR) for PE in EBV-exposed, compared with unexposed group. Mean IQ scores were compared between these groups; effect of IQ on the EBV-PE association was examined. Potential confounders included age, gender, ethnicity, social class, household crowding, and concurrent depression and anxiety. RESULTS About 25% of the sample was exposed to EBV at age 4. EBV exposure was associated with subsequent risk of definite PE in adolescence; OR 5.37 (95% CI 1.71-16.87), which remained significant after confounding adjustment. EBV-exposed individuals compared with unexposed performed worse on all IQ measures; mean difference in full-scale IQ 4.15 (95% CI 0.44-7.87); however, this was explained by socio-demographic differences. The EBV-PE association was not explained by IQ. CONCLUSIONS Early-life exposure to EBV is associated with PE in adolescence, consistent with a role of infection/immune dysfunction in the aetiology of psychosis.

Abstract
Typically reported as vivid, multisensory experiences which may spontaneously resolve, hallucinations are present at high rates during childhood. The risk of associated psychopathology is a major cause of concern. On the one hand, the risk of developing further delusional ideation has been shown to be reduced by better theory of mind skills. On the other hand, ideas of reference, passivity phenomena, and misidentification syndrome have been shown to increase the risk of self-injury or heteroaggressive behaviors. Cognitive psychology and brain-imaging studies have advanced our knowledge of the mechanisms underlying these early-onset hallucinations. Notably, specific functional impairments have been associated with certain phenomenological characteristics of hallucinations in youths, including intrusiveness and the sense of reality. In this review, we provide an update of associated epidemiological and phenomenological factors (including sociocultural context, social adversity, and genetics, considered in relation to the psychosis continuum hypothesis), cognitive models, and neurophysiological findings concerning hallucinations in children and adolescents. Key issues that have interfered with progress are considered and recommendations for future studies are provided.

Abstract
BACKGROUND The study of hallucination-like experiences (HLEs) in non-clinical populations is increasingly used to corroborate etiological models of psychosis. This method capitalizes on the absence of confounding factors that typically affect the study of hallucinations in clinical subjects. AIM To estimate the prevalence of HLEs in young adults; validate the mutidimensionality and explore the correlates of latent HLEs clusters. METHODS Cross-sectional survey design. The extended 16-item Launay-Slade Hallucination Scale (LSHS-E) and the 12-item General Health Questionnaire (GHQ-12) were administered to 649 Italian college students (males: 47%). Confirmatory factorial analysis was used to test multidimensionality of the LSHS-E. Hierarchical nested, progressively constrained models were used to assess configural, metric and scalar invariance of the LSHS-E. Latent class analysis was used to test the existence of different profiles of responding across the identified hallucination-proneness dimensions. RESULTS Factor analysis showed that the four-factor model had the best fit. Factors were invariant across demographic variables and levels of psychological distress. Three latent classes were found: a large class with no HLEs (70% of participants), a multisensory HLEs class (18.8%), and a high hallucination-proneness class (11%). Among those reporting high levels of HLEs, approximately half reported scores indicative of considerable psychological distress. CONCLUSIONS Although HLEs have a relatively high prevalence in the general population, the majority of those experiences happen in isolation and are not associated to psychological distress. Approximately half of those individuals experiencing high levels of HLEs report significant psychological distress. This may be indicative of general risk for mental health conditions rather than specific risk for psychosis.

Abstract
OBJECTIVE Schizophrenia is associated with atopy and increased inflammatory markers. We report a population-based longitudinal study of the associations between childhood atopic disorders, subsequent serum inflammatory markers, interleukin 6 (IL-6) and C-reactive protein (CRP), and the risk of psychotic experiences (PEs). METHOD PEs were assessed at age 13 years (n=6785). Presence of clinician-diagnosed atopic disorders (asthma and eczema) was determined from parent-completed questionnaires at age 10 years (n=7814). Serum IL-6 and CRP were measured at age 9 years (n=5076). Logistic regression examined the association between (1) atopy and PEs, (2) inflammatory markers and PEs, and (3) mediating effects of inflammatory markers on the atopy-PEs association. Linear regression examined the association between atopy and inflammatory markers. Age, gender, social class, ethnicity and body mass index were included as potential confounders. RESULTS At age 10 years, about 14% of the sample was reported to have asthma, 12% eczema, and 7% both asthma and eczema. Compared with children with no atopy, risk of PEs at age 13 years was increased for all of these groups; adjusted odds ratios (95% CI) were, respectively, 1.39 (1.10-1.77), 1.33 (1.04-1.69), and 1.44 (1.06-1.94). Atopy was associated with increased serum IL-6 and CRP; however, this did not mediate association between atopy and PEs. Inflammatory markers were not associated with later PEs. CONCLUSION Childhood atopic disorders increase the risk of psychotic experiences in adolescence. Follow-up of these individuals will be useful to determine the effect of atopy and inflammation on different trajectories of early-life PEs.

Abstract
Recognizing positive psychotic symptoms and their diagnostic context in youth is challenging. A large minority say they "hear things others do not hear," though they seldom present with complaints of hallucinations or delusions. Few have schizophrenia spectrum disorder, but many have other psychiatric disorders. Frequently, they have psychotic symptoms for an extended period before diagnosis. Clinicians should understand psychotic symptoms and their differential diagnoses. This article reviews the epidemiology, associated diagnoses, and prognosis of hallucinations and delusions in youth. Strategies for optimizing the clinical diagnostic interview, appropriate laboratory tests, indications for psychological testing, and rating scales are reviewed.

Abstract
Over the years, the prevalence of auditory verbal hallucinations (AVHs) have been documented across the lifespan in varied contexts, and with a range of potential long-term outcomes. Initially the emphasis focused on whether AVHs conferred risk for psychosis. However, recent research has identified significant differences in the presentation and outcomes of AVH in patients compared to those in non-clinical populations. For this reason, it has been suggested that auditory hallucinations are an entity by themselves and not necessarily indicative of transition along the psychosis continuum. This review will examine the presentation of auditory hallucinations across the life span, as well as in various clinical groups. The stages described include childhood, adolescence, adult non-clinical populations, hypnagogic/hypnopompic experiences, high schizotypal traits, schizophrenia, substance induced AVH, AVH in epilepsy, and AVH in the elderly. In children, need for care depends upon whether the child associates the voice with negative beliefs, appraisals and other symptoms of psychosis. This theme appears to carry right through to healthy voice hearers in adulthood, in which a negative impact of the voice usually only exists if the individual has negative experiences as a result of their voice(s). This includes features of the voices such as the negative content, frequency, and emotional valence as well as anxiety and depression, independently or caused by voices presence. It seems possible that the mechanisms which maintain AVH in non-clinical populations are different from those which are behind AVH presentations in psychotic illness. For example, the existence of maladaptive coping strategies in patient populations is one significant difference between clinical and non-clinical groups which is associated with a need for care. Whether or not these mechanisms start out the same and have differential trajectories is not yet evidenced. Future research needs to focus on the comparison of underlying factors and mechanisms that lead to the onset of AVH in both patient and non-clinical populations.

Abstract
BACKGROUND Factor analysis has been used to identify potential clinical subtypes of mania in pediatric bipolar disorder. Results vary in the number of factors retained. The present study used a formal diagnostic instrument to examine how symptoms of mania in young people are expressed, depending on age of symptom onset and current age. METHODS Trained clinicians completed the Schedule of Affective Disorders and Schizophrenia for School-Age Children (K-SADS) Mania Rating Scale (MRS) with parents of 163 children with child-onset of symptoms (before age 12), 94 adolescents with child-onset of symptoms, and 90 adolescents with adolescent-onset of symptoms (after age 12). Factor analysis of symptom ratings during the most severe lifetime manic episode was performed for each age group. RESULTS Symptom factor structures were established for each age group. Two factors were evident for children with child-onset of symptoms ("activated/pleasure seeking" and "labile/disorganized"), one factor was present for adolescents with child-onset of symptoms ("activated/pleasure seeking/disorganized") and two factors were evident for adolescents with adolescent-onset of symptoms ("activated/pleasure seeking" and "disorganized/psychotic"). The factor structures for children with child-onset and adolescents with adolescent-onset of symptoms were highly similar, with the latter factor structure including psychotic symptoms. LIMITATIONS Limitations include reliance on retrospective parent report and potential issues with generalizability. CONCLUSIONS Findings suggest mania symptomatology is largely similar when examined by both age of onset and current age, with some notable differences. Specifically, psychotic symptoms begin emerging as a distinct factor in adolescents with adolescent-onset of symptoms.
