This review examines the effectiveness of semantic feature analysis
as an intervention to improve naming abilities for persons with aphasia. METHOD:
A systematic search of the literature identified 11 studies that met the
pre-determined inclusion criteria. Two independent raters evaluated each study
for methodological quality and assigned appropriate levels of evidence using the
Single Case Experimental Design scale. To determine clinical effectiveness,
effect sizes using Cohen's d were calculated if sufficient data were available.
Alternatively, percent of non-overlapping data was calculated. RESULTS: Results
indicated that methodologically sound research has been conducted to determine
the effectiveness of semantic feature analysis for persons with aphasia using
single subject research designs. When using Cohen's d, the majority of
participants showed a small effect size. However, when percent of non-overlapping
data was calculated, a large treatment effect was present for the majority of
participants. CONCLUSIONS: Semantic feature analysis was an effective
intervention for improving confrontational naming for the majority of
participants included in the current review. Further research is warranted to
examine generalization effects.
