Trauma is nearly ubiquitous among women experiencing homelessness (WEH). WEH develop post-traumatic stress disorder (PTSD) at rates far exceeding the general population. The consequences of untreated PTSD can cascade, exacerbating existing physical, mental, and social health inequities, placing this population at risk for disproportionate biopsychosocial health adversity. Despite the outsized impact of PTSD, WEH are less likely to access or receive appropriate trauma-focused services. Understanding the unique and intersecting factors that contribute to the disproportionate PTSD toll on WEH may elucidate risk and protective factors, as well as possible intervention pathways to address the disparate trauma burden. This study employed a qualitative descriptive approach to develop understanding of the determinants of trauma risk, exposure, and outcomes among WEH. Semi-structured interviews were completed with 10 WEH, six shelter staff, four mental health professionals. Six deductively biopsychosocial model-derived themes were identified, alongside supporting categories. Themes/categories highlighted the role of biological, psychological, and socio-environmental determinants in shaping risk for and actualization of traumatic events and adverse outcomes. Trauma played an outsized role in shaping the health of WEH participants in this study, and the need for and interest in tailored trauma screening, treatment, psychoeducation options was highlighted. Recursive relationships between biopsychosocial determinants and trauma impact were identified. Participants emphasized population tailored trauma-focused interventions, specifically brief co-designed and community partner implemented interventions that address substance use behaviors, while leveraging the strengths of WEH. Addressing the marked trauma burden in WEH shows promise in promoting measurable biopsychosocial health improvements in this resilient yet overlooked population.

Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.

Introduction to Stress and Lifestyle

Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Psychological Responses to Stress01:20

Psychological Responses to Stress

Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Stereotype Content Model02:16

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Psychological and Sociocultural Causes of Schizophrenia01:29

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
