Abstract
PURPOSE
Few questionnaires to test nutrition knowledge and attitudes of older adults living independently in the community have been developed and tested to assess self-management tools such as Nutri-eSCREEN and other education programs. This study is a first step in the development of a questionnaire designed to evaluate the nutrition knowledge and attitudes of independent older adults (NAK-50+).
METHODS
The steps involved in this study were: (i) drafting initial questions based on the content of the Nutri-eSCREEN education material, (ii) using cognitive interviewing to determine if these questions were understandable and relevant (n = 9 adults ≥50 years of age), and (iii) completing test-retest reliability in a convenient community sample (n = 60 adults ≥50 years of age). Intra-class coefficients (ICC) and kappa were used to determine reliability.
RESULTS
A 33-item questionnaire resulted from this development and analysis. ICC for the total score was 0.68 indicating good agreement and thus initial reliability.
CONCLUSIONS
NAK-50+ is a face valid and reliable questionnaire that assesses nutrition knowledge and attitudes in independent adults aged ≥50 years. Further work to determine construct validity and to refine the questionnaire is warranted. Availability of the questionnaire for this age group will support rigorous evaluation of education and self-management interventions for this segment of the population.
