In recent years, there has been a proliferation of instruments for assessing mental health (MH) among autistic people. This study aimed to review the psychometric properties of broadband instruments used to assess MH problems among autistic people. In accordance with the PRISMA guidelines (PROSPERO: CRD42022316571) we searched the APA PsycINFO via Ovid, Ovid MEDLINE, Ovid Embase and the Web of Science via Clarivate databases from 1980 to March 2022, with an updated search in January 2024, to identify very recent empirical studies.

A starting point for evaluating the effectiveness of treatments should be to identify evidence gaps. Furthermore, such evaluations should consider the perspectives of patients, clinicians and carers to ensure relevance and potentially influence future research initiatives. Our approach, inspired by the James Lind Alliance methods, involved three steps.

There is a need for more knowledge of valid and standardized measures of mental health problems among children and adolescents with intellectual disability (ID). In this study, we systematically reviewed and evaluated the psychometric properties of instruments used to assess general mental health problems in this population. Following PRISMA guidelines, we reviewed empirical research published from 1980 through February 2020 with an updated search in March 2021 in Medline, Embase, PsycINFO, Health and Psychological Instruments, CINAHL, ERIC, and Web of Science databases.

Background: The objective of this systematic review was to examine the treatment effects of exercise on children and adolescents with depression compared to either other nonexercise treatments or no treatment. A study protocol was registered in PROSPERO (CRD42018101982).

Method: Cochrane Central Register of Controlled Trials (CENTRAL), Medline (Ovid), Embase (Ovid), PsycINFO (Ovid), AMED (Ovid), SPORTDiscus, PEDro, CINAHL (EBSCO), ERIC (EBSCO), Web of Science, and databases for grey literature and dissertations were searched from their inception through 30 August 2020 for randomized controlled trials.

Serotonin reuptake inhibiting drugs (SRI) have been used in the treatment of paediatric obsessive-compulsive disorder over the past 30 years. We performed a systematic review and meta-analysis of the literature to discuss the place of and evidence for the use of SRI in paediatric OCD, based on 14 publications of methodologically sound, randomized and controlled studies. Both SRI and specific SRIs were examined and comparisons of SRI, placebo, cognitive behaviour therapy (CBT), combined (COMBO) treatments (SRI+CBT) made to investigate their relative efficacy.

Background: Previous meta-analyses of paediatric obsessive-compulsive disorder (OCD) have shown much higher effect size for standard individual cognitive behaviour therapy (SI-CBT) compared with control conditions than for serotonin reuptake inhibitors (SRIs) compared with placebo. Other factors, such as systematic differences in the provided care or exposure to factors other than the interventions of interest (performance bias) may be stronger confounders in psychotherapy research than in pharmacological research.

Aims: These facts led us to review SI-CBT studies of paediatric OCD with the aim to compare the effect estimates across different comparisons, including active treatments.
