Subjective Self-Rated Speech Intelligibility and Quality of Life in Patients with Parkinson’s Disease in a Malaysian Sample
Abstract
Objectives:
This study compared the Quality of Life (QOL) of individuals with Parkinson’s disease (PD) with a healthy control from a sample in Malaysia. The relationship between the QOL, age, gender, duration of disease, self-rated speech scale, and life satisfaction level was examined.
Methods:
Fifty-four individuals with PD and 55 non-PD control adults completed the Parkinson’s Disease Questionnaire-39 (PDQ-39) and rated their speech intelligibility [Self-Rated Speech Scale (SRSS)] and life satisfaction level [Life Satisfaction Scale (LSS)] on a 10-point scale.
Results:
PD participants reported significantly lower QOL scores than the control group (Mann-Whitney U). Although there was no significant relationship between the QOL, age, gender, and duration of disease for PD participants, moderately significant correlations were observed between QOL, LSS and SRSS ratings (Spearman correlation). Individuals with PD showed lower QOL and higher concern in their communication than the control group.
Conclusion:
Identifying patients’ perception of their speech performance could help clinicians to better understand patients’ needs when delivering speech therapy services.
