Background: This study evaluated a package of Active Support (AS), which included standard training with additional video informed reflective practice. Materials & Methods: The training package was implemented as part of a service improvement initiative in four residential intellectual disability homes, using a concurrent multiple baseline across environments design. Training consisted of a 1-day workshop, and follow-up coaching. Momentary time sampling was used to measure engagement levels and staff assistance. A new observational tool was piloted to code the presence of positive and negative interactions between staff and the people with intellectual disabilities. Results: Results showed that service user engagement levels and staff assistance increased significantly following the training. There was also a significant increase in positive interactions and a significant decrease in negative interactions between staff and service users. Conclusion: The implications of these results are discussed.
