Trajectory research in children on the autism spectrum: a scoping review protocol.

ABSTRACT:

Introduction

Longitudinal trajectory methods, featuring outcome assessments at three or more time points, are increasingly being used as appropriate approaches to understand developmental pathways of people on the autism spectrum across the lifespan. Understanding the scope of this rapidly expanding body of research can help inform future trajectory studies and identify areas for potential meta-analysis as well as key evidence gaps. We present the protocol for a scoping review whose objective is to identify and summarise the scope of research that uses a longitudinal trajectory study design to examine development in children diagnosed with autism. Specifically, we will identify outcome domains and age intervals that have been well characterised, areas where further research is needed and the historical use of various longitudinal trajectory analytical approaches.

Methods and analysis

We outline the methods for the proposed scoping review according to the framework outlined by Arksey and O'Malley, with subsequent clarifications and enhancements by other authors. Using a search strategy developed by a medical librarian, we will search six databases for relevant publications. Titles and abstracts will be screened in duplicate, followed by full-text screening. Data extraction fields developed predominantly a priori from a set of guiding subquestions will be used to chart relevant data. The findings will include quantitative aggregate summaries, narrative summaries, and appraisal of trajectory studies according to our methodological subquestions. We will consult autistic self-advocate and parent-caregiver stakeholders to facilitate interpretation of the findings.

Ethics and dissemination

Research ethics approval is not required for this scoping review. The results will be presented to researcher, care professional, policy-maker and stakeholder audiences at local and international conferences, other dissemination activities and published in a peer-reviewed journal.

Project description:ImportanceAutism spectrum disorder (ASD) is a neurological condition characterized by impairments in social interaction, communication, and behavior. Occupational therapy practitioners use creative arts interventions for children with ASD, but relevant evidence for these interventions is lacking.ObjectiveTo provide occupational therapists evidence of the benefit of creative arts interventions for children with ASD by evaluating treatment efficacy and connecting the evidence with the Occupational Therapy Practice Framework: Domain and Process (4th ed.; OTPF-4).Data sourcesWe searched peer-reviewed articles in six databases: CINAHL, Cochrane, PubMed, Ovid, PsycInfo, and Scopus. Eighteen articles published between 2000 and 2020 met Level 1b or 2b evidence criteria and were retrieved for full review; 15 were included in this scoping review.Study selection and data collectionWe used Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to extract data. Inclusion criteria were as follows: (1) Level 1b or 2b study; (2) quantitative data; (3) published in English; (4) population of children (ages <18 yr); (5) primary diagnosis of ASD; and (6) creative arts intervention in the forms of drawing, painting, or coloring; music; or theater.FindingsCreative arts interventions benefited children with ASD in two OTPF-4 areas (process and social interaction) pertaining to the Performance Skills domain and one OTPF-4 area (body functions) pertaining to the Client Factors domain. We found similar effects for group and individual intervention sessions, and significant improvements required multiple sessions.Conclusions and relevanceOur findings provide evidence for the efficacy of creative arts interventions to enhance occupation-based outcomes for children with ASD. What This Article Adds: Our findings support occupational therapy practitioners' use of creative arts interventions to improve OTPF-4-based client factors and process and social interaction skills for children with ASD.

Project description:BackgroundIn many countries, children who are diagnosed with autism during the first 5 years of life are offered a range of early intervention options. These options vary considerably in the theoretical approaches and techniques applied, their intensity and duration, settings, the person/s delivering supports and the training they require. Early interventions are a significant contributor to total autism-related costs in Western countries, but only in the last 10-20 years has there been adequate outcome data to enable the comparison of different interventions' cost-effectiveness. This protocol describes a scoping review to better understand what economic evaluations have been completed in this field, and the methods used to date.MethodsWe will systematically search the following databases from their inception to 2021 for eligible studies: MEDLINE, EMBASE, PsycINFO, Econlit, PEDE, NHS EED and HTA. Full economic evaluations of any types of early intervention for children with autism prior to school entry will be included. Two reviewers will screen the studies, extract the data and assess the study quality using established checklists. The risk of bias will be assessed using the extended CHEC-list for all studies and, additionally, the Philips checklist for modelled studies. Quality of reporting will be assessed using the CHEERS checklist. A narrative synthesis will be completed to collate the findings, describe the methods used and identify which interventions have been researched from an economic perspective.DiscussionThis review will provide researchers, policymakers and service providers with current information about the economic evidence for early interventions for young children with autism and point to priorities for further research. It will inform future economic evaluations by highlighting the gaps or inconsistencies in the methods used to date. Limitations of the review will be acknowledged and discussed.Systematic review registrationOpen Science Framework: https://osf.io/sj7kt.

Project description:BackgroundA strong primary care system is vital to overall health. Research on the primary care of people with autism spectrum disorder (ASD) has mostly focused on children. A synthesis of the existing literature related to the quality of primary care for the adult population with ASD would elucidate what is known about the topic as well as inform future research and clinical practice.ObjectiveThe purpose of our scoping review is to describe what is known about the quality of primary care for adults with ASD and identify knowledge gaps.MethodsPrior to beginning the literature search, we reviewed literature related to defining both primary care and primary care quality to establish the context and concept of the research question. The search strategy was designed and executed by a research librarian. The MEDLINE, CINAHL, EMBASE, PsycINFO, and ProQuest Dissertations and Theses databases were searched for relevant literature. Grey literature will include relevant reports from government websites and associations with a focus on ASD. Two members of the research team will independently screen the academic and grey literature. Quantitative, qualitative, or mixed methods study designs involving the quality of primary care services or patient-centered care for adults with ASD are eligible for inclusion in our scoping review. Studies that make it past the full-text review will undergo data extraction and quality appraisal by 2 independent reviewers. The data extraction results will be presented in a tabular format to clearly present what is known about the quality of primary care for adults with ASD; this table will be accompanied by a narrative synthesis. Literature selected for extraction will be coded for themes, which will form the basis of a thematic synthesis. The scoping review will follow the guidance proposed by the Joanna Briggs Institute.ResultsThe search of electronic databases was conducted in October 2020, and it returned 2820 results. This research is still in progress. The results from our scoping review are expected to be available by fall 2021.ConclusionsThe results from our scoping review will be useful for guiding future research on the quality of primary care for adults with ASD.International registered report identifier (irrid)PRR1-10.2196/28196.

Project description:Objective This review aims to identify the mhealth apps delivering early intervention to support parents of children with autism spectrum disorders (ASD). We aim to explore the concept, context and methodology of implementation that is, theoretical framework, feasibility, quality of evidence, for such apps. Background To improve outcomes for children with autism, early intervention has been found to be promising. Parental training, parent psychoeducation and parent-mediated intervention are regarded as the gold standard, to achieve early childhood development goals. Digital health technologies like tele-health, web-based services, have been used to deliver this at a reduced cost. There is little evidence about their use and efficacy in empowering parents of children with ASD. Inclusion criteria The studies reporting the use of mhealth apps to support parents of children with ASD, in community settings, school settings, special schools, clinics, hospitals or child development centres. There will be no exclusion based on region, gender or sociocultural factors. The types of studies included will be quantitative, qualitative, mixed-methods study designs, case reports, grey literature, systematic reviews, clinical trials and studies reporting feasibility of digital mhealth applications. Method Using the NICE Healthcare Databases Advanced Search, we will search the following databases: MEDLINE, PUBMED, CINAHL, EMBASE, PsycINFO, Cochrane Library, EbscoHost, Sabinet, SAGE Journals, Directory of Open Access Journals, BioMed Central, Scopus, ScienceDirect. Furthermore, grey literature will be searched through Google Scholar, ShodhGanga, JSTOR, CORE, EBSCO, DOAJ, BASE. The searches will be limited to the age range of children between 2 and 6 years with ASD, and the date range is from the inception of the database to the current date. The terms for the ASD will be combined with terms for parent, early intervention and digital mhealth to identify eligible studies.
