Development and psychometric validation of a vestibular symptom severity scale.
Article in Brazilian journal of otorhinolaryngology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo develop the Self-Perception of Vestibular Symptom Severity Scale (EGV) and to evaluate the validity and reliability of the interpretations derived from its scores.
methodsThis methodological validation study included 100 adults with vestibular symptoms. Instrument development involved an exploratory literature review, item construction through a Delphi panel, and content validation by expert judges. Structural validity was examined separately for the frequency and intensity subscales using exploratory and confirmatory factor analyses. Internal consistency was assessed using Cronbach's alpha. Test-retest reliability (7- and 14-day intervals) was analyzed using the Intraclass Correlation Coefficient (ICC). Measurement error was estimated through the standard error of measurement and smallest detectable change. Construct validity was evaluated through hypothesis testing by examining associations between EGV scores and validated instruments measuring functional impact, physical activity, autonomy, and attentional awareness.
resultsAll items demonstrated satisfactory content validity (coefficients ≥0.80). Exploratory factor analysis supported a unidimensional structure in both subscales (KMO > 0.94; Bartlett's test p < 0.001), with factor loadings ranging from 0.84 to 0.95. Confirmatory factor analysis indicated adequate model fit. Internal consistency was excellent (α > 0.90). Test-retest reliability showed high stability at 14-days (ICC ≥ 0.80). Higher EGV scores were significantly associated with greater functional limitation, lower physical activity levels, increased dependence, and reduced attentional awareness.
conclusionThe EGV demonstrated evidence supporting structural validity, reliability, and construct validity, supporting its clinical applicability for measuring vestibular symptom severity. The scale provides a standardized framework for monitoring symptom progression in clinical practice and research. LEVEL OF EVIDENCE: 4:
