Selection of graphic symbol collections by speech and language pathologists for students with autism spectrum disorder

Graphic symbol collections are often implemented in assessment and interventions with clients with autism spectrum disorder (ASD). The selection of the optimal collection is considered by speech-language pathologists (SLPs) a challenging task. Since limited literature exists on the factors that guide this selection specifically for clients with ASD, this study aimed to explore those in detail, for which a qualitative design was followed. Semi-structured interviews were conducted with SLPs who shared their views on the factors that affect this selection. A thematic analysis of the interview transcripts took place. The outcomes showed that SLPs focus on multiple factors, grouped as SLP-related factors (e.g., training on collection(s) of graphic symbols), client-related factors (e.g., age), family-related factors (e.g., opinions on graphic symbol collections), factors related to graphic symbol collections (e.g., iconicity), practical factors (e.g., cost), and assessment/intervention factors. Assessment methods such as trial-error and dynamic assessment to assist with this selection were also reported. The findings revealed the need to support SLPs in optimal symbol collection selection through evidence-based practices, helping to ensure that symbol selection is tailored to the communication needs of students with ASD.
