About
This study aims to evaluate the relative efficacy of biofeedback and traditional treatment for residual speech errors when both are delivered via telepractice. In a single-case randomization design, up to eight children with RSE will receive both visual-acoustic biofeedback and traditional treatment via telepractice. Acoustic measures of within-session change will be compared across sessions randomly assigned to each condition. It is hypothesized that participants will exhibit a clinically significant overall treatment response and that short-term measures of change will indicate that biofeedback is associated with larger increments of progress than traditional treatment.
Full description
The COVID-19 crisis has forced speech-language pathologists to migrate from in-person delivery of speech treatment services to remote delivery via telepractice. This study will compare the efficacy of visual-acoustic biofeedback treatment versus non-biofeedback treatment in this setting. Specifically, participants will receive both visual-acoustic biofeedback treatment and non-biofeedback treatment via telepractice (Zoom call with screen-sharing) in a single-case randomization design. The hypothesis of interest is that sessions featuring visual-acoustic biofeedback will be associated with larger short-term gains than sessions featuring non-biofeedback treatment. To test this hypothesis, the study team will recruit up to 8 participants who will receive an initial treatment orientation followed by an equal dose of both types of treatment (10 sessions of visual-acoustic biofeedback and 10 sessions of non-biofeedback treatment). Participants will complete approximately two sessions per week via telepractice; each week will feature one session of each type, randomly ordered. They will also complete 4 pre-treatment baseline sessions and 3 post-treatment maintenance sessions to evaluate the overall magnitude of change over the course of treatment.
