Development and Validation of the Guide for Effective Nutrition Interventions and Education (GENIE): A Tool for Assessing the Quality of Proposed Nutrition Education Programs

Abstract

ObjectiveTo develop and validate the Guide for Effective Nutrition Interventions and Education (GENIE), a checklist of research-based quality indicators for nutrition education programs. DesignA prospective test of criterion validity and inter-rater reliability of a new tool comparing expert assessments and trained reviewer GENIE scores of the same nutrition education proposals. ParticipantsTen nutrition education experts; 13 volunteer reviewers. Variables MeasuredGENIE’s face, content, and criterion validity and inter-rater reliability compared using expert assessments and reviewer objective and subjective scores. AnalysisReviewer scores compared using Spearman correlation. Inter-rater reliability tested using intra-class correlation (ICC), Cronbach alpha, and ANOVA. Criterion validity tested using independent t test and point bi-serial correlation to compare reviewer with expert scores. ResultsCorrelation found between total objective and total subjective scores. Agreement found between reviewers across proposals and categories considering subjective scores (F = 7.21, P < .001; ICC = 0.76 [confidence interval, 0.53–0.92]) and objective scores (F = 7.88, P < .001; ICC = 0.82 [confidence interval, 0.63–0.94]). Relationship was not significant (r = .564, P = .06) between expert and reviewer proposal scoring groups (high, medium, and low). Conclusions and ImplicationsResults support the validity and reliability of GENIE as a tool for nutrition education practitioners, researchers, and program funding agencies to accurately assess the quality of a variety of nutrition program plans.
