Validation of a self-administered version of the Mediterranean diet scale (MDS) for cardiac rehabilitation patients in Canada
Bibliographic record
Abstract
The Mediterranean dietary pattern has been linked with lower incidence of cardiovascular disease and the Mediterranean diet scale (MDS) has been created to incorporate and test the inherent characteristics of this dietary pattern. This study aimed to psychometrically validate a self-administered version of the MDS in cardiac rehabilitation (CR) patients in Canada. To establish content validity, the scale was reviewed by an expert interdisciplinary panel. A final version of the tool was tested in 150 CR patients. Cronbach's alpha was 0.69. All ICC coefficients met the minimum recommended standard. Factor analysis revealed four factors, all internally consistent. Criterion validity was supported by significant differences in total scores by duration in CR. Construct validity was supported by agreements between the self-administered MDS and original MDS in all items and with the 3-day food record in 8 of 13 items. In conclusion, the self-administered version of the MDS demonstrated good reliability and validity.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
