This study validated a digital photo method against a traditional home food inventory checklist for assessing home food environments in 53 participants, finding moderate initial agreement that improved to substantial after removing problematic food items. The photo method was significantly preferred by participants over the checklist.
This preliminary validation study compared a digital photography method against a traditional home food inventory (HFI) checklist for assessing the home food environment. Fifty-three participants completed an HFI, submitted photos of household foods, and indicated their method preference. Researchers independently completed HFIs from participant photos. Concurrent validity was assessed using kappa coefficients via ANOVA, and inter-rater reliability was evaluated through randomized block analysis. Initial reviewer-participant agreement across all 46 food items was moderate (κ = 0.54). After removing 11 items that diminished agreement, adjusted kappa rose to 0.61, indicating substantial agreement. Inter-rater reliability was high (p > 0.98), with no significant difference among reviewers. A total of 79.2% of participants preferred the photo method (p = 0.01). Limitations include a convenience sample that was predominantly young, female, and Hispanic or Latino, and restriction to kitchen-area food storage. The findings suggest the digital photo method is a valid, lower-burden alternative to traditional checklists for assessing home food environments.
