Abstract

The aim of this work was to critically examine the methodological quality of recent treatment research in speech-language pathology, focusing specifically on group-design studies (randomized, controlled trials and quasi-experimental-design studies). We also considered whether methodological quality differed as a function of a particular study's treatment focus (i.e. literacy, language, speech, fluency, voice), the age group studied (pre-school-age child; school-age child; adult), the year of publication, or the publishing journal. In total, 53 treatment studies published in the last 10 years in three journals of the American Speech-Language-Hearing Association (ASHA) were selected for analysis using Downs and Black's (1998) reliable, valid rating tool for examining methodological quality. The results indicated that the quality of the treatment studies was highly variable in terms of the 25 indicators of quality studied, and that there were few systematic differences in quality attributable to treatment focus, age group studied, year of publication, or the publishing journal. Implications for evidence-based practice and study reporting are discussed.
