Structural validity of the Trunk Assessment Scale for Spinal Cord Injury (TASS) with Rasch analysis for individuals with spinal cord disorders.
Article in The journal of spinal cord medicine, 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
objectiveTo confirm the structural validity of the Trunk Assessment Scale for Spinal Cord Injury (TASS). PARTICIPANTS AND
methodsWe evaluated 104 Japanese individuals with a spinal cord injury (SCI) (age 63.5 ± 12.2 years; 64 with tetraplegia) with the TASS 1-3 times. We conducted a Rasch analysis to assess the TASS' unidimensionality, fit statistics, category probability curve, ceiling/floor effects, local independence, reliability, and difference item function (DIF).
resultsThe TASS was observed to be a unidimensional and highly reproducible scale of item difficulty hierarchy that sufficiently identifies the superiority of the examinee's ability. The TASS was easy for the participants of this study. One TASS item was a misfit based on the infit and outfit mean square; another item also showed a DIF contrast for age. Several items were found to require a synthesis or modification of the content. The TASS showed a floor effect, and most of the non-scorers were individuals with a complete SCI.
conclusionOur findings clarify the structural validity of the TASS, and our analyses revealed that the TASS includes an unfitness item and was less challenging for individuals with SCIs. The improvements suggested by these results provide important information for modifying the TASS to a more useful instrument.
