The confidence and competence of speech language pathologists in augmentative and alternative communication: a scoping review

Augmentative and alternative communication (AAC) is a core component of speech pathology practice. However, international literature has highlighted that speech language pathologists (SLPs) may not feel confident or competent in this area. Confidence and competence are critical factors in therapy as they can impact the quality-of-service provision. The purpose of this scoping review was to investigate the confidence/competence of SLPs in AAC. A systematic scoping search was conducted using four databases to identify relevant literature. The first two authors reviewed 30% of abstracts and the remaining 70% were reviewed by the first author. Full-text screening applied the same review approach. Data was then extracted and organized according to the research questions. Thirteen studies were included in the review. All thirteen used self-assessment to measure confidence or competence with one study also using an objective evaluation. Overall, confidence and competence levels varied based on the specific clinical task and etiology of the client in addition to being influenced by prior training, clinician age, workplace and AAC caseload. While current research provides a snapshot of the SLP workforce, it is limited in that the research predominantly uses self-assessment measures, is cross-sectional and is quantitative in nature. Further research into the confidence and competence of SLPs in AAC is required, specifically how confidence and competence can be defined and developed.
