Brief Report: Single-Session Interventions for Mental Health Challenges in Autistic People: An (Almost) Empty Systematic Review.

Abstract

Single-session interventions (specific, structured programs that intentionally involve just one visit or encounter with a clinic, provider, or program) have been proven to prevent or reduce mental health challenges and reduce barriers to access. This review aimed to identify and synthesise literature on the acceptability, feasibility, effectiveness, or efficacy of (non-pharmacological) single-session interventions for autistic people. Four databases (Scopus, MEDLINE, PsycINFO, and ProQuest) were searched in 12.7.2023, with no date restrictions. Search terms were selected to identify articles reporting on single-session interventions in autistic people. Two raters screened titles/abstracts of 286 articles and full text of 17 articles, resulting in just two included articles, reporting on 46 participants. Risk of bias was assessed with the Quality Assessment with Diverse Studies (QuADS). The two included papers report on specific techniques taught within a single visit to a clinic using pre- and immediate post-intervention questionnaires. One study also reported on cortisol levels pre and post. Neither study reported on acceptability or feasibility of single-session interventions. However, there was insufficient quality evidence to evaluate the effectiveness or efficacy of single-session interventions for autistic people. Although there is substantial research on single-session interventions in the broader population, there is a lack of research into such approaches for autistic people. This is a missed opportunity to evaluate a potential means of support for those at elevated risk of mental health challenges and unmet mental health service need. Future research should co-produce and co-evaluate such approaches as a priority.
