Examining Evacuation Decisions of People Experiencing Homelessness During Natural Disasters Using the Protective Action Decision Model (PADM)

In this dissertation, I examined the lived experiences of people experiencing homelessness (PEH) and their perceptions of protective actions when making evacuation decisions during disasters or extreme weather events. Compared to other members of society, individuals experiencing homelessness during disasters face unique challenges, including a lack of shelter, transportation, access to news, and the need to carry all their belongings. This vulnerability is further heightened when natural disasters occur, as they lack physical protection, leading to increased exposure to hazards and adverse weather effects.
The literature on homeless evacuation decision-making is limited (Donley & Wright, 2012), and the direct experiences of PEH and their decision-making processes during natural disasters remain underexplored (Brookfield & Fitzgerald, 2018; Brown et al., 2013; Every & Thompson, 2014; Gaillard et al., 2019; Settembrino, 2017). Additionally, the unsafe living conditions of PEH, coupled with the uncertainty of the COVID-19 virus, posed unique challenges for homeless communities, increasing the risk of virus transmission and exacerbating social disparities.
In this study, I explored PEH’s lived experiences and perspectives when making evacuation decisions during disasters. I utilized Lindell and Perry's (2012) Protective Action Decision Model (PADM) as the theoretical framework. The PADM enabled me to analyze various factors influencing the evacuation decisions of PEH, including their physical aspects (shelter use and mobility) and social context (relationships with other PEH and employment). The findings presented in this study are the result of 41 in-depth semi-structured field interviews with PEH living unsheltered in Fort Lauderdale, Broward County.
