Challenges in Measuring Applied Cognition: Measurement Properties and Equivalence of the Functional Assessment in Acute Care Multidimensional Computerized Adaptive Test (FAMCAT) Applied Cognition Item Bank.
Article in Archives of physical medicine and rehabilitation, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 present challenges in assessment of applied cognition and the results of differential item functioning (DIF) analyses used to inform the development of a computerized adaptive test (CAT).
designMeasurement evaluation cohort study. DIF analyses of 107 items were conducted across educational, age, and sex groups. DIF hypotheses informed the evaluation of the results.
settingHospital-based rehabilitation from a single hospital system.
participantsA total of 2216 hospitalized patients (N=2216).
interventionsNot applicable.
main outcome measuresApplied cognition item pool from multiple sources.
resultsMany items were hypothesized to show DIF, particularly for age. Information was moderately high in the lower (cognitive disability) tail of the distribution, but some items were not informative. Reliability estimates were high (>0.89) across all studied groups, regardless of estimation method. There were 35 items with DIF of high magnitude and 19 with accompanying supportive hypotheses.
conclusionsA key clinical tool in inpatient rehabilitation medicine is assessment of applied functional cognitive ability to inform patient-centered rehabilitation strategies to improve function. This was the first study to evaluate measurement equivalence of the applied cognition item pool across large samples of hospitalized patients. Although about one-third of the item pool evidenced DIF or low discrimination, results supported placement of most items into the bank and its use across groups differing in education, age, and sex. Six items were classified with salient DIF, defined as consistent DIF of high magnitude and or impact, with confirmatory directional DIF hypotheses, generated by content experts. These were recommended for adjustment or removal from the bank; 4 were deleted from the bank and 2 had lowered CAT exposure (administration frequency) rates. Many items hypothesized to show DIF contained content measuring constructs other than applied cognition such as physical frailty, perceptual difficulties, or skills reflective of greater educational attainment. Challenges in measurement of this construct are discussed.
