The present study provides a systematic replication of the Jennett, Harris, and Delmolino (2008) study comparing discrete trial instruction (DTI) and mand training on the acquisition of mands for children with autism spectrum disorder (ASD). An adapted alternating treatment design was implemented across three participants. Independent mands, variation in requested items, and duration of sessions were assessed across conditions. Generalization probes were conducted to assess generalization across communication partners (e.g., novel research assistants), along with a maintenance probe one-week post-training. Furthermore, a concurrent-chains arrangement was implemented to assess participants’ preference for teaching strategies. All participants reached mastery criterion quickest with mand training. Implications, limitations, and areas of future research are discussed.
