Abstract Background Millions of U.S. families are exposed to unhealthy levels of wildfire smoke (WFS) annually. Interventions to reduce the impacts of WFS on child health are urgently needed, especially for families in vulnerable communities, where WFS exposure is high yet resources and opportunities for self-protection are limited. Little is known about parents’ current engagement in protective behaviors, a knowledge gap that challenges development of feasible and acceptable interventions. We aimed to address this gap in a rural community in Washington State with high concerns about WFS and child health. Methods We conducted community meetings and utilized an existing framework of behavioral change to draft a conceptual model of barriers and facilitators of WFS protective actions. Using this model, we identified hypothesized determinants of protective behaviors (N = 11) that could be characterized by surveying parents about perceptions of WFS and experiences in past fires. Surveys were administered by local college students at community events and online, in English and Spanish. Linear regression with robust standard errors estimated associations between z-scores of determinants of action and total action score, a sum of frequencies of protective actions (N = 6) taken in past smoke events. Predictors of frequencies of each specific action were also characterized in exploratory analyses. Results Of N = 199 participating parents, 84.8% were Hispanic, 55.3% were born in Mexico, and 58.8% had an annual income familismo, prevalent in Hispanic and immigrant populations, and a strength that WFS interventions should leverage.
