Acute Stress Symptoms After Forcible and Substance-Involved Rapes

The Impact On Eye Movement And Desensitization Reprocessing Of Incomplete Memory In A Drug-Facilitated Rape: A Single Case Study

In a drug-facilitated sexual assault (DFSA), the person's level of intoxication may result in incomplete memory. This paper describes eye movement and desensitization reprocessing (EMDR) with client-centered adaptations to address an incomplete trauma memory in a 26-year-old woman. The client was experiencing PTSD, characterized by nightmares and derealization. Therapy followed standard EMDR procedures with three minor modifications to help the client maintain current awareness. Although the memory remained incomplete, the client-centered adaptations promoted working through of the clients' trauma responses (e.g. disorientation, physical sensations) and a sense of competence and self-confidence were restored. At the end of reprocessing, and at follow-up, the client was no longer experiencing nightmares or derealization and her wellbeing had improved.

Drug-facilitated sexual assault, impaired trauma memory, and implications for mental health treatment

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.
