Purpose:
This scoping review aimed to synthesize evidence on the psychometric properties of measurement instruments used to assess people with aphasia (PWA) after stroke. In constructing support for PWA, a comprehensive assessment is vital, yet evidence on measurement accuracy is limited.
Materials And Methods:
Six databases (PubMed, MEDLINE, EMBASE, PsycINFO, Web of Science, and Ichushi-Web) were searched for studies up to 2023. Four authors independently screened studies examining the psychometric properties of instruments for PWA. Data were classified according to the Research Outcome Measurement in Aphasia (ROMA) Core Outcome Set (COS), focusing on language, communication, emotional well-being, and quality of life (QOL), and on four key instruments: Western Aphasia Battery-Revised (WAB-R), Scenario Test, GHQ-12, and SAQOL-39. Psychometric properties were appraised using the COSMIN criteria.
Results:
From 12,150 records, 34 studies covering 37 instruments were included; participants were mostly ≥60 years and >6 months post-stroke. Fewer tools assessed communication, well-being, and QOL than language. Responsiveness and measurement error were rarely evaluated; ROMA instruments WAB-R and GHQ-12 were absent. Sufficient properties supported 2 languages, 5 communication, 1 well-being, and 3 QOL instruments.
Conclusions:
Major gaps persist-limited validation, scant responsiveness/measurement error evidence, and weak support even for COS instruments.

Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.
01:20Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:29Measures of Intelligence
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...
