Conclusions
DWELL is an online Facebook intervention aimed at improving the perceptions of participants regarding designing their home environment for wellness. The dynamic platform produced social learning, enabling the participants to be engaged with different aspects of wellness issues, and the content was delivered in reliable and enjoyable ways. The intervention was effective in increasing the knowledge and awareness, verbal engagement, intellectual engagement, behavioral engagement, and self-efficacy of a population of educated Israeli mothers of young children regarding DWELL. The intervention was also found to be effective during emerging viral threats such as COVID-19. This study contributes to nudging research and research on Facebook interventions for promoting well-being. As the intervention was found to be beneficial, it may become a prototype for similar health promotion/lifestyle interventions elsewhere.This study was completed in partial fulfillment of PhD studies and was supported by the Faculty of Medicine, Tel Aviv University, and the School of Education and Human Development, University of Miami.
