Shifting demographics—that is, the growing number of older adults in Canada and internationally—and intersecting climatic risks create a complex landscape of aging in place in disaster contexts. Some older adults are vulnerable due to their underlying health conditions and limited physical mobility. Yet they also exhibit resilience in a distinct manner, owing to their wealth of knowledge, wisdom, and ability to navigate adversities. This article elucidates potential avenues for promoting the involvement of older adults in disaster recovery efforts. Our intention is to recognize and foster older adult resilience and mitigate vulnerability by drawing upon insights from the study titled “In the Aftermath of the 2016 Alberta Wildfires: The Role of Social Work Practitioners and Human Service Professionals in Long-Term Disaster Recovery.” Employing a qualitative research approach, that study recruited 51 participants for semistructured interviews and focus groups. A thematic analysis of the collected data unveiled the pivotal roles played by social workers and human service practitioners in facilitating recovery from the 2016 wildfires in the research. Notably, three overarching themes emerged concerning the promotion of older adults' involvement in disaster recovery: fostering supportive relationships, building partnerships and enhancing collaboration, and addressing ongoing challenges. These findings offer valuable insights into how social work practitioners and human service professionals can effectively facilitate the engagement of older adults in disaster recovery initiatives. This article emphasizes the significance of actively promoting the participation of older adults in disaster mitigation efforts, thereby fostering greater resilience within communities. 展开更多

Previous studies reported that anger and hostility are often presented in the victims of a disaster. This study investigates the symptoms of anger and hostility after a wildfire disaster in a rural area of Greece. Cross sectional case control study of adult population (18-65 years old). Face to face interview. Data collected were demographic, Symptom Checklist 90-Revised for assessment of hostility, type and number of losses, trust in institutions personal and social attitudes. It was found that more of the victims of the wildfires reported symptoms of hostility compared to controls but this difference was disappeared when we adjust for other variables. Risk factors for development of hostility among the victims were mistrust in military forces and media, high levels of anxiety and distress, younger age and having higher education. It was concluded that anger and hostility after a disaster perhaps are not only related to disaster but other factors concerning demographic and personal characteristics may play an important role. 展开更多
