Outcome measures in developmental speech sound disorders with a motor basis


One challenging area of speech-language pathology is evaluating treatment change in children with speech sound disorder (SSD) with a motor basis. A clinician’s knowledge and use of outcome measures following treatment are central to evidence-based practice. This narrative review evaluates the use of outcome measures to assess treatment change in motor-based SSDs. Seven databases were searched to identify studies reporting outcomes of treatment in SSDs between 1985 and 2014. Sixty-six studies were identified for analysis, and reported outcome measures were categorized within the International Classification of Functioning, Disability and Health framework (ICF-CY). The majority of studies used perceptual methods (despite their limitations) to evaluate change at the impairment level of the ICF-CY and only three studies examined participation level factors. Accurate outcome measures that reflect the underlying deficit of the SSD as well as activity/participation level factors need to be implemented to document intervention success in this population.
