Development and validation of sport nutrition knowledge test for pre-service dieticians.
Article in BMC sports science, medicine & rehabilitation, 2026. 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
backgroundMeasuring pre-service dieticians’ sport nutrition knowledge levels seems important in order to determine their real educational needs, monitor the improvements and make required adjustments to the educational process. However, there is no valid and reliable sport nutrition knowledge test for pre-service dieticians. This study aimed to develop a valid and reliable sport nutrition knowledge test (SNK) for Turkish pre-service dieticians.
methodsParticipants were 201 pre-service dieticians who had successfully completed sport nutrition course at their departments previously. Rasch modeling was utilized to evaluate the validity and reliability of the sport nutrition knowledge test. Indices of item fit, person fit, person item/wright maps, separation index and separation-reliability index were checked to confirm test’ validity and reliability.
resultsResults showed that item difficulty and item discrimination of the SNK test met the required standards for educational assessment. According to fit statistics, all items were within acceptable MNSQ (0.5 to 1.5) and ZSTD (+ 2.0 to -2.0) ranges, except four items (items 1, 13, 16 and 26). Moreover, high item and person reliability indices and excellent level of item and person separation indices were determined.
conclusionsSNK test for pre-service dieticians has been developed and validated using multiple relevant methods. The test can be used to assess the SNK levels of pre-service dieticians and advocate for the importance of adding and/or increasing a specific sport nutrition education for whom working with athletic population.
