Objective: This investigation examined the effects of a virtual non-programmed prolonged speech intensive therapy program on stuttering of adults who stutter (AWS). The objective of this study was to determine if the treatment would decrease the participants’ (a) percent syllable stuttered (%SS), (b) perception of their stuttering severity via the Self-Assessment Severity Rating Scale (SASRS), and if so, (c) were participants able to maintain their fluency levels during a 2-week maintenance program. Methods: Four adult participants with a perception of moderate to moderate-severe stuttering disorder were included in this A-B-A nonconcurrent multiple baseline across participants investigation. The dependent variables (DV) were the participants’ frequency of %SS and the participants’ perception of stuttering severity. The independent variable (IV) was the implementation of a virtual four week intensive nonprogrammed prolonged speech program. Results: Results revealed positive outcomes for both measures. All four participants demonstrated a level change between phases A and B. Upon entering the maintenance phase (Phase A2), all participants revealed a continued decrease in severity perception and a maintained %SS. Conclusion: The findings demonstrated a positive treatment effect on the perception of stuttering severity and frequency of %SS, and levels were maintained throughout the maintenance phase. Further investigation examining the participants’ speech naturalness or pre- and post-intervention data is warranted.
