This systematic review is put forth to examine the quality of services provided to non-English speakers when using an interpreter to receive services in the field of speech-language pathology. In order to accomplish this, there was an electronic search of the available research. All studies included in this review met specific inclusion criteria such as being published between 2000 and 2014 in peer-reviewed journals, among other criteria. These studies collectively included 380 participants including speech-language pathologists (SLPs), interpreters, clients and family members of clients. Although the studies were all valuable in demonstrating a need for improved quality of services for those people who do not speak English, there were significant limitations to the research. Some of the limitations that are notable include the lack of research in the United States for one specific language. Through this systematic review, it is evident that there is a great need for more research in the field of interpreters in speech-language pathology in order for clinicians to be able to provide the highest level of care for their clients.
