The Role of Trauma in Mothers' COVID-19 Vaccine Beliefs and Intentions.

Abstract

ObjectiveResearch on COVID-19 vaccine beliefs has focused primarily on adults’ intentions to vaccinate themselves; however, many parents will also face decisions about vaccinating their children. In this study, we examine how maternal posttraumatic stress disorder (PTSD) and trauma history relate to mothers’ beliefs and intentions about the COVID-19 vaccine for themselves and their children.MethodsA total of 240 mothers with a mental health history participating in a parenting study answered online survey questions via Prolific. Questions assessed: (a) trauma indictors (past diagnosis, current symptoms, and lifetime exposure to events); (b) vaccine measures (intentions for self and child, COVID-19 vaccine confidence, general vaccine perceived safety, reasoning about vaccine intentions, sources of influence on intentions); and (c) possible explanatory variables (institutional distrust, negative worldviews). ANCOVAs and regression analyses were used.ResultsWhen compared with mothers with other mental health diagnoses, mothers with a PTSD history had significantly less confidence in the COVID-19 vaccine and less intent to get the vaccine for themselves or their child. These effects were explained by greater institutional distrust (i.e., significant indirect effects). Mothers with a previous PTSD diagnosis also expressed different reasons for vaccine hesitancy (e.g., less belief in science) and ascribed less influence to healthcare and governmental sources in vaccine decision-making.ConclusionFindings highlight the potential utility of a trauma-informed approach in efforts to reduce COVID-19 vaccine hesitancy. For mothers with a history of PTSD, addressing institutional distrust, including towards the healthcare industry, may be an important element to consider in the content, delivery, and mode of vaccine messaging.
