Parents of young children with autism are often taught to deliver interventions which involve several different types of strategies. Research suggests that parents can usually learn to deliver these interventions but not much is known about their use of each specific intervention strategy. This study included five mothers of young children with autism who participated in a 12-week parent training program based on the Early Start Denver Model. We measured their use of 18 different ESDM strategies before, during, and 1 month after the training program. We found that parents increased the number of strategies that they used during the training program. There were differences between mothers in terms of the ESDM strategies that they used the most during the training. We also found that some of the strategies were more closely related to children's levels of engagement and language than others. This suggests that parent training should be adapted to suit each parent's needs.
