The time that patients wait to enroll in CR may affect the number of patients who choose to attend, and longer wait times may mean fewer patients will benefit from CR participation. Programs should be encouraged to undertake quality improvement initiatives to ensure wait times are not negatively impacting patient enrollment and ultimately preventing patients from benefiting from CR participation. Further research is needed to establish evidence-based wait time benchmarks and interventions to promote timely access to CR services.

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.
