Meta-Analysis Review
BACKGROUND
Early-onset psychosis (EOP) refers to the development of a first episode of psychosis before 18 years of age. Individuals at clinical high risk for psychosis (CHR-P) include adolescents and young adults, although most evidence has focused on adults. Negative symptoms are important prognostic indicators in psychosis. However, research focusing on children and adolescents is limited.
AIMS
To provide meta-analytical evidence and a comprehensive review of the status and advances in the diagnosis, prognosis and treatment of negative symptoms in children and adolescents with EOP and at CHR-P.
METHOD
PRISMA/MOOSE-compliant systematic review (PROSPERO: CRD42022360925) from inception to 18 August 2022, in any language, to identify individual studies conducted in EOP/CHR-P children and adolescents (mean age <18 years) providing findings on negative symptoms. Findings were systematically appraised. Random-effects meta-analyses were performed on the prevalence of negative symptoms, carrying out sensitivity analyses, heterogeneity analyses, publication bias assessment and quality assessment using the Newcastle-Ottawa Scale.
RESULTS
Of 3289 articles, 133 were included ( = 6776 EOP, mean age 15.3 years (s.d. = 1.6), males = 56.1%; = 2138 CHR-P, mean age 16.1 years (s.d. = 1.0), males = 48.6%). There were negative symptoms in 60.8% (95% CI 46.4%-75.2%) of the children and adolescents with EOP and 79.6% (95% CI 66.3-92.9%) of those at CHR-P. Prevalence and severity of negative symptoms were associated with poor clinical, functional and intervention outcomes in both groups. Different interventions were piloted, with variable results requiring further replication.
CONCLUSIONS
Negative symptoms are common in children and adolescents at early stages of psychosis, particularly in those at CHR-P, and are associated with poor outcomes. Future intervention research is required so that evidence-based treatments will become available.

Meta-Analysis
RATIONALE
Children with neurodevelopmental disorders such as attention-deficit hyperactivity disorder (ADHD), autism, developmental language disorder (DLD), intellectual disability (ID), and social (pragmatic) communication disorder (SPCD) experience difficulties with social functioning due to differences in their social, emotional and cognitive skills. Previous systematic reviews have focussed on specific aspects of social functioning rather than broader peer functioning and friendships.
OBJECTIVE
To systematically review and methodologically appraise the quality and effectiveness of existing intervention studies that measured friendship outcomes for children with ADHD, autism, DLD, ID, and SPCD.
METHOD
Following PRISMA guidelines, we searched five electronic databases: CINAHL, Embase, Eric, PsycINFO, and PubMed. Two independent researchers screened all abstracts and disagreements were discussed with a third researcher to reach consensus. The methodological quality of studies was assessed using the Cochrane Risk of Bias Tool for Randomised Trials.
RESULTS
Twelve studies involving 15 interventions were included. Studies included 683 children with a neurodevelopmental disorder and 190 typically-developing children and diagnosed with either autism or ADHD. Within-group meta-analysis showed that the pooled intervention effects for friendship across all interventions were small to moderate (z = 2.761, p = 0.006, g = 0.485). The pooled intervention effect between intervention and comparison groups was not significant (z = 1.206, p = 0.400, g = 0.215).
CONCLUSION
Findings provide evidence that some individual interventions are effective in improving social functioning and fostering more meaningful friendships between children with neurodevelopmental disorders and their peers. Effective interventions involved educators, targeted child characteristics known to moderate peer functioning, actively involved peers, and incorporated techniques to facilitate positive peer perceptions and strategies to support peers. Future research should evaluate the effectiveness of friendship interventions for children with DLD, ID and SPCD, more comprehensively assess peer functioning, include child self-report measures of friendship, and longitudinally evaluate downstream effects on friendship.

Meta-Analysis Review
In recent decades, the connections between academic skills, such as reading, writing, and calculation, and motor skills/capacities have received increasing attention. Many studies provided evidence for motor difficulties in children and adolescents with dyslexia, prompting the need for a meta-analysis to combine these multiple findings. Therefore, we conducted a meta-analysis using PsycINFO, Pubmed, and SportDiscus as scientific databases. A total of 572 studies were analyzed following several stringent inclusion criteria, resulting in the inclusion of 23 peer-reviewed studies in the final analysis. Our results showed that children and adolescents with dyslexia displayed significant different performances in multiple motor tasks and these differences persisted also when the type of motor task was considered as moderator in the analysis. The present findings are in accordance with the literature that supports a close connection between reading disabilities and difficulties in motor skills/capacities.

OBJECTIVE
Anxiety disorders are highly prevalent worldwide; however, the literature lacks a meta-analytic quantification of the risk posed by fathers' anxiety for offspring development. This systematic review and meta-analysis aimed to provide a comprehensive estimate of the magnitude of the association between paternal anxiety and emotional and behavioral problems of offspring.
METHOD
In February 2022, Web of Science, Ovid (Embase, MEDLINE, PsycINFO), Trip Database, and ProQuest were searched to identify all quantitative studies that measured anxiety in fathers and emotional and/or behavioral outcomes in offspring. No limits were set for offspring age, publication language, or publication year. Summary estimates were extracted from the primary studies. Meta-analytic random-effects 3-level models were used to calculate correlation coefficients. Quality was assessed using the Newcastle-Ottawa Scale. The study protocol was preregistered with PROSPERO (CRD42022311501) and adhered to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) reporting guidelines.
RESULTS
Of 11,746 records identified, 98 were included in the meta-analysis. Small but significant associations were found between paternal anxiety and offspring emotional and behavioral problems overall (r = 0.16, 95% CI [0.13, 0.19]) and behavioral (r = 0.19, 95% CI [0.13, 0.24]), emotional (r = 0.15, 95% CI [0.12, 0.18]), anxiety (r = 0.13, 95% CI [0.11, 0.16]), and depression (r = 0.13, 95% CI [0.03, 0.23]) problems. Some significant moderators were identified.
CONCLUSION
Paternal mental health is associated with offspring development, and the offspring of fathers with anxiety symptoms or disorders are at increased risk of negative emotional and behavioral outcomes, in line with the principles of multifinality and pleiotropy. The substantial heterogeneity among studies and the overrepresentation of White European American groups in this literature highlight the need for further research.

Meta-Analysis
BACKGROUND
Psychotic disorders are characterized by structural and functional abnormalities in brain networks. Neuroimaging techniques map and characterize such abnormalities using unique features (e.g., structural integrity, coactivation). However, it is unclear if a specific method, or a combination of modalities, is particularly effective in identifying differences in brain networks of someone with a psychotic disorder.
METHODS
A systematic meta-analysis evaluated machine learning classification of schizophrenia spectrum disorders in comparison to healthy control participants using various neuroimaging modalities (i.e., T1-weighted imaging (T1), diffusion tensor imaging (DTI), resting state functional connectivity (rs-FC), or some combination (multimodal)). Criteria for manuscript inclusion included whole-brain analyses and cross-validation to provide a complete picture regarding the predictive ability of large-scale brain systems in psychosis. For this meta-analysis, we searched Ovid MEDLINE, PubMed, PsychInfo, Google Scholar, and Web of Science published between inception and March 13th 2023. Prediction results were averaged for studies using the same dataset, but parallel analyses were run that included studies with pooled sample across many datasets. We assessed bias through funnel plot asymmetry. A bivariate regression model determined whether differences in imaging modality, demographics, and preprocessing methods moderated classification. Separate models were run for studies with internal prediction (via cross-validation) and external prediction.
RESULTS
93 studies were identified for quantitative review (30 T1, 9 DTI, 40 rs-FC, and 14 multimodal). As a whole, all modalities reliably differentiated those with schizophrenia spectrum disorders from controls (OR = 2.64 (95%CI = 2.33 to 2.95)). However, classification was relatively similar across modalities: no differences were seen across modalities in the classification of independent internal data, and a small advantage was seen for rs-FC studies relative to T1 studies in classification in external datasets. We found large amounts of heterogeneity across results resulting in significant signs of bias in funnel plots and Egger's tests. Results remained similar, however, when studies were restricted to those with less heterogeneity, with continued small advantages for rs-FC relative to structural measures. Notably, in all cases, no significant differences were seen between multimodal and unimodal approaches, with rs-FC and unimodal studies reporting largely overlapping classification performance. Differences in demographics and analysis or denoising were not associated with changes in classification scores.
CONCLUSIONS
The results of this study suggest that neuroimaging approaches have promise in the classification of psychosis. Interestingly, at present most modalities perform similarly in the classification of psychosis, with slight advantages for rs-FC relative to structural modalities in some specific cases. Notably, results differed substantially across studies, with suggestions of biased effect sizes, particularly highlighting the need for more studies using external prediction and large sample sizes. Adopting more rigorous and systematized standards will add significant value toward understanding and treating this critical population.

Review
This study aimed to determine, through a systematic review, the relationship between Reactive Attachment Disorder (RAD) and the presence of psychopathology in children and adolescents, and to determine the existence of differences in terms of internalising and externalising psychological problems between the RAD group and groups with other disorders or with typical development. Following the PRISMA methodology, a search was carried out in the Web of Science, PubMed and Scopus databases. The search yielded 770 results, of which only 25 met the inclusion criteria. The results indicate a relationship between the presence of RAD and/or disinhibited social engagement disorder (DSED), with the presence of internalising and externalising problems. These difficulties are more present in children with RAD compared to children without personal difficulties, or children with DSED, children with autism, children with intellectual disabilities or children with hyperactivity. It can be concluded that the presence of RAD has negative consequences on the mental health of children and adolescents, with these being greater in the inhibited group than in the disinhibited group, and with respect to children with autism or hyperactivity.

Genuine Memory Deficits as Assessed by the Free and Cued Selective Reminding Test (FCSRT) in the Behavioural Variant of Frontotemporal Dementia. A Systematic Review and Meta-analysis Study.
The current diagnostic criteria for the behavioural variant of frontotemporal dementia (bvFTD) foresee a relative sparing of long-term memory. Although bvFTD patients were thought to report secondary memory deficits associated with prefrontal dysfunctions, some studies indicated the presence of a "genuine memory deficit" related to mesial temporal lobe dysfunctions. Among various neuropsychological tests, the Free and Cue Selective Reminding Test (FCSRT) has been recommended to distinguish genuine from apparent amnesia. We conducted a systematic review and a random effect Bayesian meta-analysis to evaluate the nature and severity of memory deficit in bvFTD. Our objective was to determine whether the existing literature offers evidence of genuine or apparent amnesia in patients with bvFTD, as assessed via the FCSRT. On 06/19/2021, we conducted a search across four databases (PMC, Scopus, Web of Science, and PubMed). We included all studies that evaluated memory performance using the FCSRT in patients with bvFTD, as long as they also included either cognitively unimpaired participants or AD groups. We tested publication bias through the Funnel plot and Egger's test. To assess the quality of studies, we used the Newcastle-Ottawa quality assessment scale adapted for cross-sectional studies. We included 16 studies in the meta-analysis. The results showed that bvFTD patients perform better than AD patients (pooled effects between 0.95 and 1.14), as their memory performance stands between AD and control groups (pooled effects between - 2.19 and - 1.25). Moreover, patients with bvFTD present both genuine and secondary memory disorders. As a major limitation of this study, due to our adoption of a rigorous methodology and stringent inclusion criteria, we ended up with just 16 studies. Nonetheless, our robust findings can contribute to the ongoing discussion on international consensus criteria for bvFTD and the selection of appropriate neuropsychological tools to facilitate the differential diagnosis between AD and bvFTD.

Review
Multimorbidity-the coexistence of at least two chronic health conditions within the same individual-is an important global health challenge. In high-income countries (HICs), multimorbidity is dominated by non-communicable diseases (NCDs); whereas, the situation may be different in low- and middle-income countries (LMICs), where chronic communicable diseases remain prominent. The aim of this systematic review was to identify determinants (including risk and protective factors) and potential mechanisms underlying multimorbidity from published longitudinal studies across diverse population-based or community-dwelling populations in LMICs. We systematically searched three electronic databases (Medline, Embase, and Global Health) using pre-defined search terms and selection criteria, complemented by hand-searching. All titles, abstracts, and full texts were independently screened by two reviewers from a pool of four researchers. Data extraction and reporting were according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Methodological quality and risk of bias assessment was performed using the Newcastle-Ottawa Scale for cohort studies. Data were summarized using narrative synthesis. The search yielded 1782 records. Of the 52 full-text articles included for review, 8 longitudinal population-based studies were included for final data synthesis. Almost all studies were conducted in Asia, with only one from South America and none from Africa. All studies were published in the last decade, with half published in the year 2021. The definitions used for multimorbidity were heterogeneous, including 3-16 chronic conditions per study. The leading chronic conditions were heart disease, stroke, and diabetes, and there was a lack of consideration of mental health conditions (MHCs), infectious diseases, and undernutrition. Prospectively evaluated determinants included socio-economic status, markers of social inequities, childhood adversity, lifestyle behaviors, obesity, dyslipidemia, and disability. This review revealed a paucity of evidence from LMICs and a geographical bias in the distribution of multimorbidity research. Longitudinal research into epidemiological aspects of multimorbidity is warranted to build up scientific evidence in regions beyond Asia. Such evidence can provide a detailed picture of disease development, with important implications for community, clinical, and interventions in LMICs. The heterogeneity in study designs, exposures, outcomes, and statistical methods observed in the present review calls for greater methodological standardisation while conducting epidemiological studies on multimorbidity. The limited evidence for MHCs, infectious diseases, and undernutrition as components of multimorbidity calls for a more comprehensive definition of multimorbidity globally.

Review
AIMS
To evaluate the effectiveness of eHealth interventions to reduce stress and promote mental health in healthcare professionals, and to compare the efficacy of different types of programs (guided vs. self-guided; 'third-wave' psychotherapies vs. other types).
BACKGROUND
Healthcare workers present high levels of stress, which constitutes a risk factor for developing mental health problems such as depression and anxiety. eHealth interventions have been designed to reduce these professional's stress considering that the characteristics of this delivery method make it a cost-effective and very appealing alternative because of its fast and easy access.
DESIGN
A systematic review of quantitative studies.
METHODS
A comprehensive database search for quantitative studies was conducted in PubMed, EMBASE and Cochrane (until 1 April 2022). The systematic review was conducted in accordance with the PRISMA and SWiM reporting guidelines. The quality of the studies was assessed using the National Heart, Lung and Blood Institute tools.
RESULTS
The abstracts of 6349 articles were assessed and 60 underwent in-depth review, with 27 fulfilling the inclusion criteria. The interventions were classified according to their format (self-guided vs. guided) and contents ('third-wave' psychotherapies vs. others). Twenty-two interventions emerged, 13 of which produced significant posttreatment reductions in stress levels of health professionals (9 self-guided, 8 'third wave' psychotherapies). Significant effects in improving depressive symptomatology, anxiety, burnout, resilience and mindfulness, amongst others, were also found.
CONCLUSION
The evidence gathered in this review highlights the heterogeneity of the eHealth interventions that have been studied; self-guided and 'third-wave' psychotherapy programs are the most common, often with promising results, although the methodological shortcomings of most studies hinder the extraction of sound conclusions.

Meta-Analysis Review
Early-onset depression contributes significantly to the global health burden and has long-term negative effects. This meta-analysis collates and examines the effectiveness of family-based interventions, where family members are involved in the treatment of depression in children and adolescents. A literature search was performed up to 8th March 2023. Randomised controlled trials of family-based interventions were included for participants aged 3-18 years with a diagnosis of major depressive disorder or dysthymia, according to the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013) or with a score above a cut-off on a standardised self-report depression measure. The overall effect size for treatment versus active control was g = 0.22 (95% confidence interval [CI]: -0.05-0.50) (nine studies; 659 participants), and for treatment versus non-active control it was g = 0.46 (95% CI: -0.09-1.01) (four studies; 385 participants). Effect sizes were not statistically significant, and heterogeneity was high, ranging between I = 64.3-81.1%. Subgroup analysis comparing attachment-based family therapy with family therapy using other theoretical frameworks did not yield a significant difference between the two. The effects of family-based therapies were larger than those in the comparison groups, but family-based therapy did not demonstrate a significant treatment benefit compared to the controls. More randomised controlled trials are warranted, considering that evidence for other psychotherapies for depression in children and adolescents, indicates modest effects. Family-based therapy may be an alternative for children and adolescents whose needs are not addressed by these treatments.
