Development and Psychometric Validation of the Guideline-Concordant Low Back Pain Vignette (GCLBP-V) in Undergraduate Physiotherapy Students.

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
Background: Low back pain (LBP) is a leading cause of global disability. Clinical guidelines recommend maintaining activity, early return to work, exercise, and avoiding bed rest. Although vignette-based assessments are common in pain education, they are rarely psychometrically evaluated. This study aimed to develop and validate the Guideline-Concordant Low Back Pain Vignette (GCLBP-V) in undergraduate physiotherapy students. Methods: A cross-sectional study included 126 undergraduate physiotherapy students in Jordan. The four-item GCLBP-V assesses guideline-concordant recommendations across activity, work, exercise, and bed rest. Content validity was evaluated via expert review (n = 8) and cognitive pre-testing. Construct validity was assessed using known-groups comparisons (junior vs senior) and convergent validity with pain knowledge and pain-related beliefs. Test-retest reliability (intraclass correlation coefficient, ICC (2,1)), measurement error (standard error of measurement, SEM; minimal detectable change at 95% confidence, MDC Results: Content validity was excellent (scale-level average content validity index, S-CVI/Ave = 0.969). Known-groups validity was supported by higher scores among senior versus junior students (Cliff's δ = 0.510, p < 0.001). The GCLBP-V showed moderate associations with pain knowledge ( Conclusion: The GCLBP-V demonstrates acceptable psychometric properties as a brief measure of guideline-concordant clinical recommendations. It addresses a key methodological gap by providing a standardized vignette-based behavioral outcome measure suitable for group-level comparisons in pain education. Further research should evaluate responsiveness and generalizability across different populations, disciplines, and settings.
