Stress can have physical, emotional, cognitive, and behavioral effects and is made worse by factors like poverty and job stress. Coping strategies like problem-focused coping, emotion-focused coping, and meditation can help manage stress. Post-traumatic stress disorder is related to experiencing or witnessing traumatic events and can cause flashbacks, aggression, and substance abuse. Programs like REACH that provide therapy and teach coping skills to veterans and their families have been shown to effectively reduce PTSD symptoms. Continued therapy is important for treating PTSD in victims and helping their loved ones learn to cope as well.
