Objective:
To evaluate the fidelity of a digital nutrition education intervention program for community-dwelling older adults.
Design:
Cluster randomized controlled trial with 5 conditions, including attendance records, class observations, preassessment and postassessment of nutrition and technology knowledge, postprogram surveys, and qualitative analysis.
Setting:
Congregate Meal Program sites in San Antonio, Texas (n = 12).
Participants:
Older adults (n = 319) INTERVENTION: In-person technology training and support followed by online nutrition education.
Measurable Outcome/Analysis:
Fidelity was scored on an average percentage scale (benchmark > 75%). Qualitative analysis of focus groups.
Results:
A total of 319 participants completed the postprogram survey with responses indicative of high satisfaction rates with Google Classroom (96%), online nutrition sessions (96%), and weekly socials (72%). Attendance was 97% and 94%, respectively, for the technology and online nutrition classes, and the average fidelity was > 90%. Older adults (n = 49) participated in focus groups. Key themes included comfort with technology, motivation for the intervention, and the value of supplemental resources.
Conclusions And Implications:
Providing technology access, training, and online nutrition education implemented with high fidelity increased participants' comfort and motivation to engage in online nutrition programs. These findings can inform future interventions and the development of digital nutrition education programs for older adults.
