Parkinson's disease is an incurable, progressive neurodegenerative brain disorder. Individuals living with Parkinson's disease often face considerable challenges in managing the progressive decline of their symptoms and maintaining their quality of life (Broadfoot et al., 2019). During the progression of PD, 75-90% of individuals will have a speech and voice disorder (National Center for Voice and Speech, 2019). The communication disorder most commonly associated with PD is hypokinetic dysarthria (HKD). Many individuals with PD may have significant difficulty communicating and participating effectively in a variety of speaking situations due to their communication deficits (Dykstra et al., 2015). Addressing an individuals perceived quality of communication and their perceived communication effectiveness should be an essential target during intervention due to the implications it has on the psychological well-being and prognosis for people with PD. Participants in this study were recruited from individuals previously diagnosed with Parkinson's disease attending the SPEAK OUT! & LOUD Crowd® program. The research questions included (1) Does the implementation of the SPEAK OUT! ® and the LOUD Crowd® program have a positive effect on participants’ perceived quality of communication (PQOC), and (2) Do these programs have a significant positive effect on participants perceived communicative effectiveness (PCE)? The Voice Handicap Index (VHI) and the Communicative Effectiveness Survey- Revised (CESR®) were utilized in this research study. The surveys were administered prior to the SPEAK OUT!® training and following the completion of this portion of the program. They were administered every 16 weeks while the participant was in the LOUD Crowd® training during the duration of this project. It was hypothesized that participants' PQOC related to their voice and their PCE will improve following the implementation of this program. Due to COVID-19 restrictions, results from this study only considered baseline scores and post-test 1 scores following the completion of the SPEAK OUT!® program. The results from this study support the hypothesis that the SPEAK OUT!® program has a positive effect on the participants’ PQOC. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2021. / FAU Electronic Theses and Dissertations Collection
