Objective:
To develop and validate the Guide for Effective Nutrition Interventions and Education (GENIE), a checklist of research-based quality indicators for nutrition education programs.
Design:
A 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.
Participants:
Ten nutrition education experts; 13 volunteer reviewers.
Variables Measured:
GENIE's face, content, and criterion validity and inter-rater reliability compared using expert assessments and reviewer objective and subjective scores.
Analysis:
Reviewer 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.
Results:
Correlation 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 Implications:
Results 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.
