Construct validity was demonstrated through extraction of 4 factors with significant loadings accounting for 68% of variance: efficiency and effectiveness of nutrition care, training and support, integration into dietetic work systems, and familiarity with apps. Internal consistency reliability overall was 0.90; 3 of 4 constructs had Cronbach α > .70. Weighted kappas for test-retest reliability indicated moderate to substantial agreement (0.43–0.76).
