Disaster Interpersonal Communication and Posttraumatic Stress Following the 2011 Joplin, Missouri, Tornado

Mental Health Impacts of Tornadoes: A Systematic Review

Tornadoes are one of the most prevalent natural hazards in the United States, yet they have been underrepresented in the disaster mental health comprehensive literature. In the current study, we systematically reviewed available scientific evidence within published research journals on tornadoes and mental health from 1994 to 2021. The electronic search strategy identified 384 potentially relevant articles. Of the 384 articles, 29 articles met the inclusion criteria, representing 27,534 participants. Four broad areas were identified: (i) Mental health impacts of tornadoes; (ii) Risk factors; (iii) Protective factors; and (iv) Mental health interventions. Overall, results showed adverse mental health symptoms (e.g., post-traumatic stress disorder, depression, anxiety) in both adult and pediatric populations. A number of risk factors were found to contribute to negative mental health, including demographics, tornado exposure, post-tornado stressors, and prior exposure to trauma. Protective factors found to contribute to positive outcomes included having access to physical, social, and psychological resources. Together, these findings can serve as an important resource for future mental health services in communities experiencing tornadoes.

Building community resilience on social media to help recover from the COVID-19 pandemic

Facing the Covid outbreaks, public health researchers share a consensus that community resilience should be maintained and strengthened because it helps mitigate the physical and emotional tolls on individuals and communities. One way to achieve the goal is to build and strengthen community resilience through social media. However, social media's role in building community resilience has been poorly understood from a behavioral perspective. Guiding by uses and gratification theory and the coping literature, we build a model to examine how social media behaviors may influence community members' perceived community resilience, providing a “bottom-up” voice to deepen our understanding of community resilience and its implications for public health. The results shows that community members' social media engagement was significantly associated with their perceived community resilience. While helping others on social media led people to perceive their communities as less resilient, the use of social media for social support helped foster social capital, leading to more perceived resilience at the collective level. Overall, social media use played important roles in shaping people's perception of community resilience, helping community members and organizations evaluate their strengths and weaknesses, and make improvement to better address future challenges in the times of global disasters.

The Influence of Information Source on COVID-19 Vaccine Efficacy and Motivation for Self-Protective Behavior

This study examined the influence of health information sources on the efficacy of the COVID-19 vaccine and other motivations for self-protective behavior. Based on the protection motivation theory, the study focused on threat appraisal factors (risk perception and perceived severity), response efficacy, and health information sources (media and interpersonal channels) as predictors for vaccine efficacy and self-protective behavior. Data were gathered in Kenya through a self-administered survey (n = 715) that was conducted at the pick of the COVID-19 pandemic. Results show that media sources (newspapers, radio, television, internet, and telephone) were viewed as more useful compared to interpersonal sources (health professionals, family, friends, and other personal influencers) for COVID-19-related information. Additionally, media sources influenced risk perception, perceived severity, response efficacy, vaccine efficacy, and self-protective behavior. Interpersonal sources were also correlated with perceived severity and response efficacy, and self-protective behavior but did not influence vaccine efficacy. The study suggests exploring the use of media and other digital sources including mobile phones to enhance threat appraisal and promote vaccine efficacy among other motivations for self-protection behavior in future pandemics or disease outbreaks, especially in resource-poor settings.

Why Family Communication Matters: the Role of Co-rumination and Topic Avoidance in Understanding Post-Disaster Mental Health

Although families can be a source of support post-disaster, depending on how they communicate about their stress, their attempts at support can be helpful or harmful. This study explored the moderating role of topic avoidance and co-rumination on post-disaster mental health (MH) in a sample of 485 parent-child dyads following severe floods affecting Texas. Parents (69.0% female) and their oldest child between the ages of 10-19 years (M = 13.75 years, SD = 2.56) completed online surveys approximately one-year post-flooding. Participants reported their flood exposure, life stressors since the disaster, topic avoidance, co-rumination, and MH symptoms (posttraumatic stress symptoms [PTSS], depression, anxiety). Structural equation models tested a moderated-mediation model of whether communication processes moderated the associations of flood exposure and life stressors on MH. They did not moderate the association of flood exposure to PTSS, but did have a moderating role for depression and anxiety. At low levels of topic avoidance, there was no association between flood exposure and child anxiety or depression. However, at mean and high levels of topic avoidance, there was a significant, positive association between flood exposure and child anxiety and depression. Co-rumination impacted both parents and children. For parents, there was no association between flood exposure and depression or anxiety when co-rumination was low or mean-level. However, flood exposure increased risk for depression and anxiety at high levels of co-rumination. A similar pattern emerged for children. Results for life stressors were nuanced. Overall, this suggests that communication can influence post-disaster MH.

Gender differences in the interaction effect of community resources and attitudes toward seeking professional help on posttraumatic stress, depression, and posttraumatic growth

The current study examined the gender differences in the interaction effect of community resources and attitudes toward seeking professional help in predicting posttraumatic stress, depression, and posttraumatic growth for female and male survivors of Hurricane Harvey. Participants were 413 adults who reported directly experiencing Hurricane Harvey, which made landfall on August 26, 2017. Purposive sampling was used to recruit participants approximately 16 months after the hurricane via an online survey. Among men, significant interaction effects of community resources and attitudes toward seeking help on posttraumatic stress, depression, and posttraumatic growth were found even after statistically controlling for age, educational attainment, income, marital status, and racial minority status. Among women, no interaction effects were found. Women with open attitudes toward seeking psychological treatment experienced higher posttraumatic stress and posttraumatic growth, and higher resources were positively associated with growth. The current study raises important implications on gender differences on community resources and attitudes toward seeking professional help after a hurricane.

Disaster Communication, Posttraumatic Stress, and Posttraumatic Growth following Hurricane Matthew

Disaster survivors may experience a range of mental health reactions that can include posttraumatic stress (PTS) and posttraumatic growth (PTG). The current study examines the associations between citizen disaster communication, PTS, and PTG among individuals in North Carolina communities impacted by Hurricane Matthew, approximately six weeks following the event. Participants who communicated more frequently following the hurricane exhibited more PTS and PTG. Communication activities focused on connecting with loved ones and cognitively restructuring the disaster experience were associated with PTS and PTG, whereas communication activities confirming disaster reports and assisting with disaster recovery were associated solely with PTG. Results illustrate the need for robust disaster communication ecologies to facilitate public disaster mental health response and coordination.
