This study examined the effectiveness of Devereux's Safe and Positive Approaches training curricula (SPA) in the reduction of injury and restraint. Several data points were collected including utilization rates of restrictive interventions, number of youth injuries, number of staff injuries, and whether the program/organization is a user or non-user of SPA. The results demonstrated statistically significant differences between SPA users and non-SPA users in utilization rates of restrictive interventions, youth injury, staff injury as well as significant and positive correlations between restraint utilization and related injury.
