ABSTRACT	The purpose of this research was to examine factors affecting voice therapy outcome and to investigate the direct and indirect factors affecting quality of life in adults with voice disorders at the speech clinic in Ramathibodi Hospital. The subjects consisted of 36 patients with voice disorders. All subjects received 10 sessions of voice therapy, each session 30 minutes per week. The voice therapy program consisted of vocal hygiene education, breathing exercise, muscle relaxation and others. Voice therapy outcome was measured by using the Grade, Instability, Roughness, Breathiness, Asthenicity, and Strain (GIRBAS) criteria and Dr. Speech program and quality of life was measured by using the Voice Handicap Index version in Thai. Obtained data were analyzed by using Descriptive and Inferential statistics (Chi-square test, Fisher’s Exact test, Independent t-test and Mann-Whitney test). It was found that the voice quality after voice therapy was significant better than before therapy (p < 0.001). The factors, such as severity of voice disorders, voice usage, accuracy and progression of voice therapy at speech clinic were significantly affected by voice therapy outcomes (p = 0.006, 0.016, 0.021 and 0.009 respectively). The quality of life after voice therapy was significantly better than before voice therapy (p < 0.001). Only duration of voice disorders, an indirect factor was affected by quality of life (p = 0.040). This finding suggested that, speech and language pathologists should consider these factors during voice therapy in adults with voice disorders.
