Evaluating the Autism Knowledge Gains, Retention, and Differences Across Participant Roles in HANDS in Autism Summer Intensive Trainings (2013–2024)

Abstract

This project analyzed over a decade’s worth of Autism Knowledge Survey – Revised (AKS-R) data collected during HANDS in Autism® Summer Intensive Trainings from 2013 to 2024. Using REDCap, Python, and Power BI, the study assessed knowledge improvements across pre-training, post-training, and follow-up periods. The results showed statistically significant increases in autism-related knowledge immediately following training, with positive retention trends over time. The analysis also revealed variations in knowledge gains based on participant roles, experience levels, and training years. Notably, 2014 and 2023 demonstrated the highest improvements, highlighting peak training effectiveness. Through structured scoring, statistical testing, and predictive modeling, the project reinforced the long-term impact of targeted, interdisciplinary autism education and provided actionable insights for enhancing future training strategies.
