This systematic review investigates the effects of semantic feature analysis treatment on confrontational naming ability in adults with non-degenerative aphasia.

The authors' initial statistical analysis of clinical effectiveness of treatment, Cohen's <em>d</em>, resulted in a small effect size for the majority of participants (suggesting limited treatment effectiveness). Percent of non-overlapping data (PND) analysis was calculated data that were inappropriate for calculation of Cohen's <em>d</em>, and these results indicated a large treatment effect for the majority of patients (suggesting highly effective treatment). Of this discrepancy, the authors state "PND may overestimate the effect of treatment, when compared to effect size <em>d</em> calculations" (p. 260). They emphasize a need for reporting of effect sizes in future studies to allow more precise calculation for treatment effectiveness.

Results indicated semantic feature analysis is an effective treatment for confrontational naming impairment in adults with nondegenerative aphasia (primarily due to stroke). Medium to large effects were reported for the majority of participants. The findings also suggest that semantic feature analysis is more effective for individuals with fluent aphasia than non-fluent aphasia. However, authors noted many of the included studies reported limited generalization of naming ability to untrained items and connected speech. Therefore further research is recommended.
