Patients reported outcome of cognitive function scale: a psychometric evaluation.
Article in Health and quality of life outcomes, 2025. 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
backgroundAssessment of cognitive function is essential to identify the impact of brain aging, disease or injury on individuals. The Short Form Cognitive Function Scale is a brief instrument, easy to use in clinical and research settings with simple interpretation. However, its psychometric properties have not been confirmed in the general Mexican population. The aim of this study was to determine the psychometric properties of the Short Form Cognitive Function Scale in the general Mexican population.
methodsAn instrumental design was conducted with 600 participants. Analyses were performed to evaluate factor structure (exploratory and confirmatory factor analysis), reliability (internal consistency), measurement invariance, construct validity (convergent and divergent) and Know-Groups Validity.
resultsA unifactorial structure of 8 items was verified with an internal consistency of α = 0.945 and a McDonald Omega index of Ω = 0.946. Measurement invariance was confirmed (ΔCFI & TLI ≤ 0.01; ΔRMSEA & SRMR ≤ 0.015), with respect to gender, age groups and geographic area of residence. Finally, the Short Form Cognitive Function Scale showed adequate convergent validity with the Subjective Well-Being variable (r =.507, p <.001), divergent with the GAD 5 (r = -.517, p <.001), and discriminant between younger and older participants (t = -5.304, p <.001).
conclusionsThe Short Form Cognitive Function Scale version for the general Mexican population presented adequate psychometric properties that make it a valid and reliable instrument for use in non-clinical and research settings in Mexico.
