Six of one, half a dozen of the other? Examining measurement properties of different potentially traumatic event polyvictimization operationalizations using a multiverse analysis framework.

Numerous differences exist between and within research projects related to assessment and operationalization of potentially traumatic events (PTEs) for youth, especially when measuring polyvictimization. However, few studies have systematically examined how polyvictimization measurement differences influence PTE's relation to functioning. This study sought to address these knowledge gaps by conducting a secondary data multiverse replication (SDMR) to systematically (re)evaluate PTE polyvictimization measurement approaches.

Geographic Variations in Urban-Rural Particulate Matter (PM) Concentrations in the United States, 2010-2019.

Fine particulate matter 2.5 (PM) is a widely studied pollutant with substantial health impacts, yet little is known about the urban-rural differences across the United States. Trends of PM in urban and rural census tracts between 2010 and 2019 were assessed alongside sociodemographic characteristics including race/ethnicity, poverty, and age.

Posttraumatic Stress Disorder Among Adults in Communities With Mass Violence Incidents.

Importance: Mass violence incidents (MVIs) are prevalent in the US and can have profound and long-lasting psychological consequences on direct survivors, but their outcomes among the broader communities where the MVI occurred are unknown.

Objective: To investigate the prevalence of and factors associated with past-year and current posttraumatic stress disorder (PTSD) among adults in communities that experienced an MVI.

Design, Setting, And Participants: This cross-sectional survey was completed between February and September 2020 with a household probability sample of adults from 6 communities that had experienced an MVI between 2015 and 2019: Dayton, Ohio; El Paso, Texas; Parkland, Florida; Pittsburgh, Pennsylvania; San Bernadino, California; and Virginia Beach, Virginia.

Prevalence and risk factors of depression in U.S. adults post mass shootings: evidence from population-based surveys of multiple communities.

Objectives: Mass violence incidents (MVIs) involving firearms, commonly referred to as "mass shootings" have become increasingly frequent in the United States. These shootings often result in immediate casualties and have far-reaching psychological impacts on survivors, witnesses, and the broader community. This study aimed to assess the prevalence and risk factors of depression within affected communities.
