This meta-analysis examines the efficacy of response elaboration training and modified-response elaboration training in individuals with aphasia. Effect size benchmarks were determined to allow for group study comparisons.

<div>Response elaboration training and modified-response elaboration training showed positive effects on content production for both treated (ES = 0.91-35.77) and untreated items (ES = -0.58-117.78) in individuals with aphasia. Positive effects were also noted at follow-up for treated (ES = 0.38-51.57) and untreated items (ES = 0.93-117.58). <br><br>In addition to providing treatment effects for individual participants, data was combined to identify small, medium, and large effect size benchmarks across studies. See Table 6 (p. 257) in the full text for group effect size benchmarks. Based on these findings, there is overall support for the use of response elaboration training as an aphasia treatment; however, the varying methodological quality of included studies warrants additional research in this area.</div>
