Translation and initial psychometric evaluation of the Danish version of the treatment expectation questionnaire (TEX-Q).

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
backgroundPatient expectations are important psychological determinants of health outcomes. The Treatment Expectation Questionnaire (TEX-Q) is a validated, multidimensional instrument for assessing treatment expectations; however, no Danish version has previously been available. This study aimed to translate and conduct an initial psychometric evaluation of a Danish version of the TEX-Q in patients undergoing spinal surgery.
methodsThe TEX-Q was translated using a structured forward-backward procedure in accordance with ISPOR guidelines, including expert review by clinicians from different professional backgrounds. Consecutive adult patients scheduled for spinal surgery at a university hospital were invited to participate. The initial psychometric evaluation followed established PROM reporting standards and included assessment of feasibility, internal consistency, test-retest reliability, floor and ceiling effects, and construct validity.
resultsThe Danish TEX-Q demonstrated high comprehensibility and linguistic clarity, with mean item ratings ranging from 5.4 to 5.8 on a six-point Likert scale. Reliability varied across domains, with good internal consistency and test-retest reliability observed for most domains. Floor effects were negligible, while ceiling effects exceeded 15% in selected domains. Construct validity analyses showed no association between the TEX-Q total score and functional disability, while only limited domain-specific associations were observed, and a small but statistically significant positive association with quality of life.
conclusionThe Danish version of TEX-Q was successfully translated and demonstrated promising initial psychometric properties in a population of patients undergoing spinal surgery. However, variability in reliability across domains warrants cautious interpretation of domain-level results. Further studies are needed to assess structural validity and confirm the psychometric properties of the instrument in larger and more diverse clinical populations.
