Personalized eHealth Intervention for Lifestyle Change in Patients with Cardiovascular Disease: Results and Feasibility of the Do CHANGE 1 Randomized Controlled Trial
ABSTRACT
Background:
Behavior change methods involving new ambulatory technologies may improve lifestyle and cardiovascular disease outcomes.
Objective:
The current study provides proof of concept analyses of an intervention aiming to increase 1) behavioral flexibility, 2) lifestyle change, and 3) quality of life. The feasibility and patient acceptance of the intervention was also evaluated.
Methods:
Patients with cardiovascular disease (N=149, age=63.57±8.30 years; 33.6% women) were recruited in the ‘Do Cardiac Health Advanced New Generated Ecosystem (Do CHANGE)’ trial, and randomized to the ‘Do CHANGE’ intervention or care as usual’ (CAU). The intervention involved a 3-months behavioral program in combination with ecological momentary assessment and intervention technologies.
Results:
The intervention was experienced as feasible and useful. A significant increase in lifestyle scores over time was found for both groups (F (2,146.6) =9.99, p<.001), which was similar for CAU and the intervention group (F (1,149.9) =.09, p=.77). Quality of life improved more in the intervention group (1.11±0.11) than CAU (-1.47±.11) immediately following intervention (3-months), but this benefit was not sustained at the 6-months follow-up (p interaction =.02) No significant treatment effects were observed for behavioral flexibility (F (1,149.0) =.48, p=.07).
Conclusions:
The Do CHANGE 1 intervention was perceived as useful and easy to use. However, no long-term treatment effects were found on the outcome measures. More research is warranted to examine which components of behavioral interventions are effective in producing long-term behavior change. Clinical Trial: Clinicaltrials.gov NCT02946281
