DWELL – Design for WELLness: An online Facebook intervention to improve knowledge, engagement, and self-efficacy in the creation of healthy home environments in a population of mothers: Randomized Controlled Trial
ABSTRACT
Background:
Designing the home environment can promote well-being. Social networks, in turn, provide learning opportunities to improve health.
Objective:
This study aimed to develop and evaluate an online Facebook intervention named DWELL: Design for WELLness. The program was created to improve knowledge, engagement, and self-efficacy in the creation of healthy home environments.
Methods:
A randomized controlled trial was conducted to assess the effect of the intervention program DWELL. The main outcome was the participants’ overall score on the DWELL index, which we developed to assess the elements of our intervention: knowledge, awareness, engagement, and self-efficacy regarding home design for wellness. The intervention was conducted in Israel and lasted 6 weeks, during the third wave of COVID-19 lockdown. Primary analysis included a multivariable model to assess DWELL at end of study while controlling for baseline characteristics.
Results:
In total, 643 participants began the program, of which 476(74%) completed the study. At the end of the study there was a statistically significant benefit to the intervention, as assessed by a multivariate model. There was a mean difference of 8.631 points (SD=1.408) in favor of the intervention group (Intervention: Mean(SD)=61.92(14.30), Control: Mean(SD)=53.29(16.374), P<.001). All five questions of DWELL had higher scores in the intervention group at the end of the study, compared to control group (P<.01).
Conclusions:
DWELL was found to be a beneficial intervention for improving perceptions regarding the design of home environments to foster wellness. Facebook was an effective platform to deliver this online intervention. DWELL may become a prototype for other health promotion interventions online. Clinical Trial: The trial is registered in the NIH Clinical Trials Registry [clinical trial number NCT03736525].
