In a recent study published in the Journal of Medical Internet Research, researchers examined the effectiveness of a novel web-based health behavior tool, the Food, Exercise, Sleep, and Stress (FESS) questionnaire, integrated into services provided by certified exercise practitioners (CEPs). This twelve-week, two-arm randomized controlled trial involved 41 participants, with a median age of 65, who were recruited from CEP clinics.
The study aimed to assess changes in health behaviors by comparing two different prompting frequencies for completing the FESS questionnaire: three times per week and daily. The questionnaire tracked health behaviors across four domains and provided health tips, with outcomes evaluated at baseline, 6 weeks, and 12 weeks.
What this study does not show
While the study reported positive or no changes in most health behaviors, it does not establish a direct causal relationship between the use of the FESS tool and improved health outcomes, as it did not measure long-term health outcomes or include a control group not using the tool.
Evidence scorecard
- Analytic validity: established
- Clinical validity: established
- Clinical utility: partial
The FESS questionnaire demonstrated feasibility and was associated with observed changes in health behaviors, particularly in diet, stress, and sleep. However, while daily use led to larger changes, compliance declined over time in both groups. The study also evaluated the validity of the exercise domain by comparing self-reported physical activity with accelerometer-derived measures, showing low rates of overreporting exercise and underreporting sedentary behavior.
This research highlights the potential of digital interventions in promoting healthy lifestyle behaviors, particularly when integrated into traditional health services. However, further studies are needed to explore the long-term effects and sustainability of such interventions.
