METHODS: We performed a PRISMA/MOOSE-compliant systematic review of the Web of Science database, from inception until 7 October 2019, to identify original studies conducted in CHR-P children and adolescents (mean age <18 years). Findings were systematically appraised around core themes: detection, prognosis and intervention. We performed meta-analyses (employing Q statistics and I (2) test) regarding the proportion of CHR-P subgroups, the prevalence of baseline comorbid mental disorders, the risk of psychosis onset and the type of interventions received at baseline. Quality assessment and publication bias were also analysed. RESULTS: Eighty-seven articles were included (n = 4,667 CHR-P individuals). Quality of studies ranged from 3.5 to 8 (median 5.5) on a modified Newcastle-Ottawa scale. Detection: Individuals were aged 15.6 ± 1.2 years (51.5% males), mostly (83%) presenting with attenuated positive psychotic symptoms. CHR-P psychometric accuracy improved when caregivers served as additional informants. Comorbid mood (46.4%) and anxiety (31.4%) disorders were highly prevalent. Functioning and cognition were impaired. Neurobiological studies were inconclusive. PROGNOSIS: Risk for psychosis was 10.4% (95%CI: 5.8%-18.1%) at 6 months, 20% (95%CI: 15%-26%) at 12 months, 23% (95%CI: 18%-29%) at 24 months and 23.3% (95%CI: 17.3%-30.7%) at ≥36 months. INTERVENTIONS: There was not enough evidence to recommend one specific treatment (including cognitive behavioural therapy) over the others (including control conditions) to prevent the transition to psychosis in this population. Randomised controlled trials suggested that family interventions, cognitive remediation and fish oil supplementation may improve cognition, symptoms and functioning. At baseline, 30% of CHR-P adolescents were prescribed antipsychotics and 60% received psychotherapy. CONCLUSIONS: It is possible to detect and formulate a group-level prognosis in adolescents at risk for psychosis. Future interventional research is required.

Commentary: The impact of Covid-19 on psychopathology in children and young people worldwide - reflections on Newlove-Delgado et al. (2023) / Samuele CORTESE in Journal of Child Psychology and Psychiatry, 64-4 (April 2023)

CORRELL, Auteur Article en page(s) : p.641-644 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract In the past 3 years, since the beginning of the Covid-19 pandemic, there has been an impressive flourishing body of publications on the impact of the pandemic and related restrictions on the mental health of children and young people. It was about time for a rigorous quantitative evidence synthesis of this large body of research. Newlove-Delgado et al. (J Child Psychol Psychiatry, 2022) took on this challenge by completing a systematic review with meta-analysis of epidemiological studies on the impact of Covid-19 on psychopathology in children and adolescents, featured in the 2023 Annual Research Review series of the Journal. Overall, this meta-analysis shows that the relationship between mental health and Covid-19 pandemic in children and adolescents is complex and, as such, it ought to be addressed by studies using rigorous methods and advanced analytic strategies. Collectively, as a field, we should and could do better with regards to the scope and quality of the studies in this area.

Common limitations of published/ongoing studies are (i) being conducted in one or few countries, (ii) the survey being available in one or few languages, (iii) targeting selected samples (e.g., clinical populations and health workers) rather than the general population, (iv) only recruiting/reporting on non-representative samples, (v) focusing often on a restricted set of mental health outcomes, missing the broader picture of mental and physical health, quality of life and functioning, (vi) failing to use a longitudinal design and (vii) collecting only parental ratings or self-rated questionnaires from children and adolescents, but not both. We discuss how the Collaborative Outcomes Study on Health and Functioning during Infection Times (COH-FIT) was designed to address some of these challenges, also highlighting its limitations.

Research in people with psychosis risk syndrome: a review of the current evidence and future directions / Christoph U. CORRELL in Journal of Child Psychology and Psychiatry, 51-4 (April 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-4 (April 2010) . - p.390-431 Titre : Research in people with psychosis risk syndrome: a review of the current evidence and future directions Type de document : texte imprimé Auteurs : Christoph U. CORRELL, Auteur ; Marta HAUSER, Auteur ; Andrea M. AUTHER, Auteur ; Barbara A. CORNBLATT, Auteur Année de publication : 2010 Article en page(s) : p.390-431 Langues : Anglais (eng) Mots-clés : Schizophrenia psychosis risk-syndrome prodrome early-recognition early-intervention biomarker DSM-V Index. décimale : PER Périodiques Résumé : After decades of research, schizophrenia and related psychotic disorders are still among the most debilitating disorders in medicine. The chronic illness course in most individuals, greater treatment responsiveness during the first episode, progressive gray matter decline during early disease stages, and retrospective accounts of 'prodromal' or early illness signs and symptoms formed the basis for research on the psychosis risk syndrome (PRS), known variably as 'clinical high risk' (CHR), or 'ultra-high risk' (UHR), or 'prodromal'. The pioneering era of research on PRS focused on the development and validation of specific assessment tools and the delineation of high risk criteria. This was followed by the examination of conversion rates in psychosis risk cohorts followed naturalistically, identification of predictors of conversion to psychosis, and investigation of interventions able to abort or delay the development of full psychosis. Despite initially encouraging results concerning the predictive validity of PRS criteria, recent findings of declining conversion rates demonstrate the need for further investigations. Results from intervention studies, mostly involving second-generation antipsychotics and cognitive behavioral therapy, are encouraging, but are currently still insufficient to make treatment recommendations for this early, relatively non-specific illness phase. The next phase of research on PRS, just now beginning, has moved to larger, 'multisite' projects to increase generalizability and to ensure that sufficiently large samples at true risk for psychosis are included. Emphasis in these emerging studies is on: 1) identification of biomarkers for conversion to psychosis; 2) examination of non-antipsychotic, neuroprotective and low-risk pharmacologic and non-pharmacologic interventions; 3) testing of potentially phase-specific interventions; 4) examination of the relationship between treatment response during PRS and prognosis for the course of illness; 5) follow-up of patients who developed schizophrenia despite early interventions and comparison of illness trajectories with patients who did not receive early interventions; 6) characterization of individuals with outcomes other than schizophrenia-spectrum disorders, such as bipolar disorder and remission from PRS, including false positive cases; and 7) assessment of meaningful social and role functioning outcomes. While the research conducted to date has already yielded crucial information, the translation of the concept of a clinically identifiable PRS into clinical practice does not seem justified at this point.
