Effects of PTSD, Emotion Regulation Difficulties and Polyvictimization on Day-to-Day Negative Affect and Craving Among People Who Use Methamphetamines, Cocaine or Opioids

This study examined the effects of experiencing multiple types of violence (i.e., polyvictimization) and difficulties regulating emotions on day-to-day negative affect and craving in adults reporting substance use. These findings demonstrate how polyvictimization is associated with higher day-to-day craving, not accounted for by PTSD symptoms or difficulties regulating negative emotions.
