BACKGROUND: Sexual assault (SA) is a highly prevalent global public health problem and a robust predictor of posttraumatic stress disorder (PTSD), substance use disorder (SUD), and suicidality. A large percentage are drug or alcohol facilitated (DFSA), impairing trauma memory and affecting the application of evidence-based treatments. Despite these problems, few have investigated DFSA-specific mental health (MH) needs.
OBJECTIVE: Goals of this study were (1) to identify psychological sequelae characterizing DFSA towards explaining why symptoms have been treatment-refractory, comparing survivors with involuntary substance ingestion (forced, covert: DFSA-I), voluntary ingestion (DFSA-V), and non-DFSA; and (2) to determine how impaired trauma memory relates to the development of PTSD and depression symptoms.
METHOD: Data from a retrospective chart review of 74 adults receiving SA MH services at an outpatient trauma center are presented. The sample includes a 2-year cohort seen acutely at an urban rape treatment center. The study is one of the first to examine therapy records beyond case studies for DFSA. Logistic, Poisson, and negative binomial regression analyses of quantitative data and qualitative thematic analysis of trauma cognitions and treatment foci were conducted.
RESULTS: DFSA-V had five times greater odds of SUD, and notable substance-related self-blame compared to DFSA-I. DFSA-I had prominent relationship distress and self-blame for missing danger of perpetrator drugging. Survivors with impaired trauma memory had significantly fewer hyper-arousal and overall PTSD symptoms, and specifically less hypervigilance. No differences were found in re-experiencing symptoms.
CONCLUSION: Impaired trauma memory is common in DFSA and is associated with fewer baseline hyper-arousal and overall PTS. Despite this, DFSA issues including re-experiencing symptoms that are particularly distressing without the ability to cognitively connect the intrusions contribute to increased treatment needs. Impaired memory limits the application of evidence-based treatments, and collectively these findings call for the development of trauma-specific treatment protocols to enhance recovery for DFSA survivors. HIGHLIGHTS: Survivors of drug-facilitated sexual assault have prominent PTSD including reexperiencing, though trauma memory may not be encoded. • Those absent trauma memory have less hyperarousal, but DFSA complications explain why it is treatment refractory and inform treatment development.
