- Abstract
Initial language training with children with autism often focuses on the production of single‐word requests (i.e., mands). As a child progresses in treatment, it is desirable to increase the mean length of utterance (MLU) of requests. The present study examined treatment outcomes of behavioral intervention designed to increase the MLU of requests in a larger sample of children with language delays (n = 30). Intervention consisted of prompts and differential reinforcement for lengthier requests, and trials were conducted flexibly throughout the treatment session. A non‐concurrent multiple baseline across participants design was utilized to establish experimental control, and MLU intervention consisted of a baseline and treatment phase for each participant. Nonoverlap of all pairs (NAP) was employed to estimate an effect size. Overall treatment effects were medium to large (average NAP = 0.89; average d = 2.36), and the majority of the sample (70%) demonstrated strong treatment effects. Results suggest that targeted behavioral intervention to increase the length of requests can be effective for children with autism and associated language delays.
