Linking Sensory Integration and Processing With Mental Health in Autism: A Retrospective Review of Survey Data.

IMPORTANCE: Although a central tenet of occupational therapy practice, evidence-based practice is at times overrepresented by research and can overlook the contributions of clinical expertise, the lived experience, and context. This survey affords the occupational therapy practitioner the opportunity to understand sensory integration and processing (SI/P) as experienced by autistic adults. OBJECTIVE: To explore the following research question through a retrospective analysis of an internet-based survey: What is the relationship between the SI/P differences and mental health concerns reported by autistic adults? DESIGN: Nonexperimental; retrospective analysis of data collected from September 2018 through June 2019. The analysis team joined the project after the survey had been launched. SETTING: The Grand Sensory Survey (GSS) was available internationally through the websites and social media accounts of the Autistic Empire and STAR Institute for Sensory Processing. PARTICIPANTS: The sample included 440 total responses. Excluding responses from participants ages ≤18 yr (n = 24), 416 responses were included: n = 189 identified as autistic, n = 147 identified as nonautistic, and n = 80 did not provide a response to this query. OUTCOMES AND MEASURES: The GSS included questions about demographics, mental health, and sensory experiences. RESULTS: Both SI/P disruptions and sensory sensitivity predicted anxiety and depression (p < .001). CONCLUSIONS AND RELEVANCE: Differences in SI/P are significant factors in mental health for autistic adults. What This Article Adds: We implicate multiple aspects of SI/P and their influence on mental health among autistic adults. The autistic-led design of the survey ensures representation of issues that are pivotal to the autistic community, broadening the template for aspects of SI/P that should be considered when looking at client factors in autism and influence on function and participation. Positionality Statement: The authors deliberately use identity first language in keeping with requests from the autistic community (see https://autisticadvocacy.org/about-asan/identity-first-language/). This language is favored by autistic communities and self-advocates and has been adopted by health care professionals and researchers (Bottema-Beutel et al., 2021; Kenny et al., 2016). This article is written from the perspective of the social model of disability and a neurodiversity affirming frame of reference. Three of the five authors are autistic.

Sleep, Sensory Integration/Processing, and Autism: A Scoping Review.

The prevalence of sleep dysfunction is considerably higher in the autistic population than in the non-autistic. Similarly, the incidence of sensory reactivity differences in autism exceeds that in the neurotypical population. The basis of sleep disorders in autism is multifactorial, but sensory integration/processing concerns may play a role. Research that investigates this interplay for autistic individuals is limited but vital. In this scoping review, we examined literature addressing the following research question: What is the relationship between sleep and sensory integration/processing in autism? We included articles if they were peer-reviewed, English or Spanish, purposefully addressed sensory integration/processing differences, were sleep focused and included autism as the primary diagnosis or population. Articles were excluded if the language was not English or Spanish, research was conducted with animals, they were non-peer-reviewed, the primary population was not autistic, the sensory focus reflected a specific sensorineural loss (e.g., blindness, or deafness), there was not a clear inclusion of sensory integration/processing or sleep. We searched six databases and included all citations from the inception of each database through June 2021. The search strategy identified 397 documents that were reduced to 24 included articles after exclusion criteria were applied. The majority of studies we identified characterized the relation between sleep and sensory integration/processing differences in autism. Investigators found multiple sleep concerns such as bedtime resistance, sleep anxiety, delayed sleep onset, night awaking, and short sleep duration in autistic individuals. Identified sensory concerns focused on reactivity, finding hyper- and hypo-reactivity as well as sensory seeking across sensory domains. Co-existence of sleep concerns and sensory integration/processing differences was frequently reported. Few intervention studies showed a clear sensory focus; those that did emphasized pressure, movement, touch, and individual sensory preferences/needs. Swimming programs and massage showed promising results. No studies were of high quality. At a minimum, there is a co-existence of sensory reactivity differences and sleep concerns in autistic children, and possibly autistic adults. The relationship between poor sleep and sensory integration/processing differences is complex and multi-faceted, requiring additional research. Interventions that purposefully include a central sensory component have not been well studied in autistic children or adults. Overall studies with greater rigor and purposeful use of sensation and sensorimotor supports as a component of intervention are needed. This study was not funded.
