Objective: To develop a questionnaire that allows to evaluate the therapeutic adherence of the patients with home enteral nutrition (NED).
Method: Generation and validation of a questionnaire to evaluate medication adherence to NED. The internal consistency was verified by the Kuder-Richardson Formula 20 statistics. The construct validity was analyzed with the Varimax Rotation method with Kaiser normalization. The intra-observer and inter-observer concordance was calculated using the Kappa index.
Results: Six items of dichotomous response were determined (yes.no) by consensus grouped into two categories: knowledge and difficulties. These items offered a final score related to the adherence from 0 a 2 = low; 3 a 4 = moderate; 5 a 6 = high. The intra-observer reliability obtained a concordance equal to 1 and inter-observers 0.93. The internal consistency was 0.721. Construct validity analyzed by factor analysis by principal component with Varimax Rotation method with Kaiser normalization identified 2 main components that grouped the items in the two dimensions of the questionnaire.
Conclusion: The nutritional adherence questionnaire developed has been shown to be reliable and useful in obtaining information on adherence to nutritional treatment, with high content validity, internal consistency, construct validity and stability.
