Please provide a discussion response with APA citations and references to "The biopsychosocial perspective views trauma and stressor-related disorders as the result of interacting biological, psychological, and social factors. Biologically, exposure to trauma can dysregulate the hypothalamic-pituitary-adrenal axis and heighten the stress response, leading to hyperarousal and sleep disturbance. Psychological factors include prior mental health history, coping style, and cognitive appraisals of the event, while social variables such as family support, culture, and ongoing adversity influence recovery (Whitbourne, 2020). This model emphasizes that no single factor causes trauma disorders; instead, vulnerability and resilience emerge from the interaction of these systems. Posttraumatic Stress Disorder (PTSD) is a common trauma-related diagnosis. Core symptoms include intrusive memories or nightmares, avoidance of reminders, negative changes in mood and beliefs, and persistent hyperarousal. Symptoms must last longer than one month and cause significant impairment. Causes involve exposure to actual or threatened death, serious injury, or sexual violence, with risk increased by prior trauma, lack of social support, and neurobiological sensitivity to stress (Whitbourne, 2020). Evidence-based treatments include trauma-focused CBT, prolonged exposure, and eye movement desensitization and reprocessing. Need Assignment Help?
