THE UTILITY OF METAANALYSIS IN THE DETERMINATION OF EFFICACY OF TREATMENT IN APHASIA - A REPLY TO ROBEY (1994)

In response to Robey (1994) we argue that his judgment of our study an d conclusions (Whurr, Lorch, & Nye, 1992) are inaccurate. We point out that our study was in fact an analysis of the effects of treatment fo r aphasic patients. Further, the results obtained in Robey's analysis, though obtained via a different strategy of analysis, yielded essenti ally the same degree of overall treatment outcome effect. Thus, we con clude that while Robey does provide a different model of effect size d ata organization and measurement, the results are no different and do not in fact contradict our data.
