Multilevel communication to improve well-being during a pandemic.

The COVID-19 pandemic has highlighted existing crises and introduced new stressors for various populations. We suggest that a multilevel ecological perspective, one that researchers and practitioners have used to address some of public health's most intransigent challenges, will be necessary to address emotional distress and mental health problems resulting from the COVID-19 pandemic. Multiple levels of influence (individual, interpersonal, organizational, community, and policy) each contribute (individually and in combination) to population health and individual well-being. We use the convergence strategy to illustrate how multilevel communication strategies designed to raise awareness, educate, or motivate informed decision-making or behavior change can address various sources of information surrounding a person to synergistically affect mental health outcomes. Looking ahead, dissemination and implementation researchers and practitioners will likely need to coordinate organizations and networks to speak in complementary and resonant ways to enhance understanding of complex information related to the pandemic, mitigate unnecessary anxiety, and motivate healthy behavior to support population mental health. Plain language abstract: The current COVID-19 pandemic has threatened the mental health and well-being of various populations. The pandemic also has compounded health disparities experienced by communities of color and magnified the vast treatment gaps they experience related to behavioral health and substance use treatment access. A multilevel approach to future communication interventions focused on mental health likely will be useful, as we need to know about and address interactions with health care professionals, mass media information sources, social networks, and community influences rather than solely trying to reach people with carefully crafted videos or advertisements. Implementation researchers and practitioners likely will need to coordinate organizations and networks to speak in complementary and resonant ways to support population mental health.
