A BRIEF, MOBILE INTERVENTION TO DECREASE DEPRESSION AND LONELINESS AND IMPROVE RELATIONSHIP QUALITY DURING THE COVID-19 PANDEMIC

Introduction: Effective, scalable interventions to address depression and loneliness and improve the quality of social relationships are needed for public health in pandemic and non-pandemic contexts. Towards this end, a randomized, controlled trial tested a mobile-based intervention, derived from social psychological and relationship science, for improving relational well-being and decreasing depression and loneliness. Methods: Participants were randomly assigned to either intervention (n = 719) or assessment only (n = 701) conditions and completed daily diary surveys for 28 days in the midst of the first wave of the Covid-19 pandemic. In the middle 14 days of the study, intervention participants received daily text-message suggestions for improving relational and mental well-being. Results: Results indicated that the intervention decreased depression and loneliness and improved relationships during the intervention period but these changes were not sustained when the intervention ceased. Discussion: Results are encouraging in that evidence-based suggestions can be scaled effectively but additional efforts are required to sustain improvements over time.
