Evaluating Sensory Integration Activities for Autistic Children Aged 5–7 in School Settings Introduction Sensory integration activities integrated into the school day are essential for autistic children aged 5–7, as sensory processing challenges often disrupt classroom engagement and self-regulation. A 2018 study in American Journal of Occupational Therapy found that 80% of autistic children exhibit atypical sensory processing, impacting learning. A 2021 meta-analysis in Autism Research reported that sensory interventions improve self-regulation by 25–40% in young autistic students, emphasizing the need for school-based strategies. Research Objectives and Questions Objective: Evaluate changes in sensory processing abilities following sensory integration activities. Question: How do sensory integration activities impact Sensory Profile 2 scores in autistic children aged 5–7? Objective: Observe the effects of sensory integration activities on classroom engagement and self-regulation behaviors. Question: What changes in classroom engagement (e.g., task persistence) and self-regulation (e.g., reduced meltdowns) are observed post-intervention? Objective: Explore parental perceptions of the effectiveness of sensory integration activities. Question: How do parents perceive the impact of school-based sensory integration activities on their child’s behavior and classroom performance? Methodology Study Design: Mixed-methods design with pre-post quantitative measures, structured classroom observations, and qualitative teacher/parent interviews. Participants: Autistic children aged 5–7 (Kindergarten–Grade 1) with a DSM-5 ASD diagnosis (target n=15–20). Recruited from inclusive or special education classrooms. Exclusion: Co-occurring severe neurological conditions. Teachers (n=10–12) and parents of participating students. Data Collection Tools: Quantitative: Sensory Profile 2 (SP2) to assess pre/post sensory processing abilities. Behavioral Observations: Structured observation checklists to record engagement (e.g., time on task) and self-regulation behaviors (e.g., frequency of outbursts) during 20-minute classroom sessions. Qualitative: Semi-structured interviews with teachers (30 minutes) on feasibility; parent interviews (20–30 minutes) on perceived effectiveness. Analysis Approach: Quantitative: Paired t-tests to compare pre/post SP2 scores; descriptive statistics for engagement and self-regulation frequencies. Qualitative: Thematic coding of interview transcripts using NVivo to identify themes (e.g., feasibility barriers, perceived benefits). Literature Review: Databases: PubMed, ERIC, PsycINFO. Keywords: “autism + sensory integration + school + early childhood.” Inclusion Criteria: Peer-reviewed studies (2015–2025), English, focusing on sensory interventions for autistic children aged 5–7. Analysis: Synthesis of sensory intervention types, outcomes, and school-based feasibility. Expected Outcomes and References Quantitative Improvements: Anticipated 20–30% improvement in SP2 scores, indicating enhanced sensory processing. Behavioral Patterns: Increased task persistence (e.g., 5–10 minutes longer on task) and reduced outburst frequency (e.g., 1–2 fewer per day). Qualitative Insights: Parents may report better emotional regulation at home; teachers may note improved focus but highlight time constraints. References: Schaaf, R. C., & Mailloux, Z. (2015).
