title: PTSD symptom severity as a predictor of cue-elicited drug craving in victims of violent crime.
abstract: This study examined posttraumatic stress disorder (PTSD) symptom severity as a predictor of cue-elicited craving among alcohol- and cocaine-dependent individuals with a history of at least one physical and/or sexual assault. Approximately half of the sample had current PTSD. Severity of PTSD symptoms was measured via the Impact of Events Scale-Revised (IES-R) total severity score. Subjects listened to four trials of a brief narrative imagery script followed by the presentation of an in vivo cue. The script presentation consisted of a description of either the subject's worst traumatic event or a neutral scene. The in vivo cues consisted of the presentation of either the subject's preferred drug or neutral cues. Craving was measured in response to both the script and in vivo cues. Results indicated a high degree of correlation between self-report craving and (a) PTSD symptom severity, (b) type of substance use disorder (SUD) [alcohol dependence (AD) vs. cocaine dependence (CD)], and (c) sex and race of participant. A series of stepwise multiple regressions indicated that PTSD severity was significantly predictive of trauma cue-elicited craving and drug cue-elicited craving. The results are discussed in the context of current research, theory, and clinical practice.
