概要	The Communication Confidence Rating Scale (CCRS or CRSA) is a brief self-report measure of perceived communication self-efficacy and confidence in communication situations among adults with aphasia. Unlike objective measures of language ability (Boston Diagnostic Aphasia Examination) or quality-of-life impact (Aphasia Impact Questionnaire), the CCRS focuses specifically on confidence—the degree to which a person with aphasia believes they can successfully communicate in everyday scenarios. High CCRS scores reflect psychological readiness to engage in communication despite linguistic deficits; low scores indicate anxiety and avoidance despite preserved communication ability.	The Voice Handicap Index (VHI) is a 30-item self-report questionnaire that measures the impact of voice disorders on quality of life and functional communication. Developed by Jacobson and colleagues in 1997, it quantifies the psychosocial, physical, and emotional burden of dysphonia across functional, physical, and emotional domains. Widely used in otolaryngology and speech-language pathology to assess treatment outcomes and monitor disease progression.
