This review aimed to summarize the psychometric properties of aphasia-related instruments for Chinese speakers.
Systematic review of 41 publications in English and Chinese databases identified 26 aphasia instruments.
Measurement properties examined included Cronbach’s α, test-retest reliability, interrater reliability, and criterion validity.
Risk of bias assessed with COSMIN Risk of Bias checklist and evidence quality using COSMIN methodology.
Most instruments demonstrated high-evidence reliability, but many lacked adequate internal consistency and criterion validity.
32 studies focused on post-stroke aphasia, highlighting a common population.
Quality assessment showed variable results, indicating a need for improved reporting standards.
