Detailed Description

Each year, approximately 100,000 women in the United States present to sexual assault nurse examiner (SANE) programs for evaluation after experiencing sexual assault. A wealth of data demonstrates that the development of adverse posttraumatic neuropsychiatric sequelae such as posttraumatic stress disorder (PTSD) is common in this population and that individuals with a history of traumatic stress exposure and/or posttraumatic stress symptoms are at increased risk. Unfortunately, no secondary preventive interventions are currently widely available that can prevent PTSD among those at high risk. Moreover, the 10% of sexual assault survivors in the United States who live in rural communities face even greater barriers to obtaining care. Written exposure therapy is an evidence-based, low-cost intervention that has demonstrated efficacy in treating chronic PTSD symptoms after a variety of traumatic stress exposures, including sexual assault. In addition, telehealth delivery of written exposure therapy for PTSD has yielded similar treatment outcomes and lower attrition compared to in-person delivery. The present protocol will assess the feasibility and preliminary efficacy of telehealth-delivered written exposure therapy as a secondary preventive intervention for sexual assault survivors in the acute aftermath of trauma exposure. This pilot trial will randomize N=80 women who received SANE care following sexual assault to five sessions of either virtual written exposure therapy (n=40) or virtual unemotional writing control (n=40). The same experienced therapists will deliver both interventions via telehealth/video sessions. Participant follow-ups will be performed remotely via REDCap self-report surveys by trained assessors and research associates. Results of this trial will demonstrate the feasibility and potential efficacy of written exposure therapy to reduce the development of PTSD after sexual assault and will provide the data necessary to design and support a large-scale trial.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Written Exposure Therapy
Five sessions of remotely-delivered written exposure therapy.
Behavioral: Written Exposure Therapy
During session one of the written exposure therapy intervention, the therapist will provide psychoeducation about PTSD and the rationale for the proposed intervention. Psychoeducation and treatment rationale are scripted to ensure consistency. The therapist will provide the participant with instructions for writing about the same trauma memory (their recent sexual assault) during each session. They will be asked to look back at the event and write for 30 minutes about the details of the event including what they saw, heard, felt, smelled, etc. without regard for spelling or grammar. The participant will self-report Subjective Units of Distress Scale (SUDS) levels to the therapist at the beginning and end of each session. After 30 minutes, the therapist will ask the participant to stop writing, review the experience of writing and discuss as needed, and conclude the session.
Placebo Comparator: Unemotional Writing
Five sessions of remotely-delivered non-emotional writing.
Behavioral: Unemotional Writing
During the unemotional writing sessions, the therapist will read instructions for writing about non-emotional topics. The participant will be instructed to describe what they did the day before the session from the time they woke up until the time they went to bed, as objectively as possible, without regard for spelling or grammar. The therapist will then leave the participant with a written version of the instructions for 30 minutes while the participant writes. The participant will self report Subjective Units of Distress Scale (SUDS) levels to the therapist at the beginning and end of each session. After 30 minutes, the therapist will ask the participant to stop writing, review the experience of writing and discuss as needed, and conclude the session.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in PTSD Symptom Severity Over Time
Time Frame: Baseline, Week 4, Week 8, Month 3, Month 5
The PTSD Checklist for DSM-5 (PCL-5) is a 20-item self-report measure designed to assess PTSD symptoms as defined by the Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5). Each item of the PCL-5 is scored on a five-point scale ranging from 0 ("not at all") to 4 ("extremely"). Items are summed to provide a total severity score (range = 0-80), with higher scores indicating greater symptom severity. PTSD symptom severity will be compared between treatment groups over time.
Baseline, Week 4, Week 8, Month 3, Month 5
Recruitment Rates
Time Frame: Baseline
To assess feasibility of the study recruitment protocol, the proportion of eligible participants who enroll in the study and are randomized will be calculated.
Baseline
Retention Rates
Time Frame: Month 5
To assess feasibility of the study protocol, the proportion of participants who complete the study protocol, according to study arm and in total, will be calculated.
Month 5
Treatment Completion Rates
Time Frame: Week 8
To assess feasibility of the treatment protocol, treatment completion rates will be calculated according to study arm and in total. Treatment completers will be defined as participants who complete at least 4 out of 5 written exposure therapy or control sessions.
Week 8

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Pain Symptom Severity and Extent Over Time
Time Frame: Baseline, Week 4, Week 8, Month 3, Month 5
Pain severity and extent will be evaluated using a modified version of the Regional Pain Scale, where each item is scored on a 0-10 numeric rating with 0 indicating no pain and 10 indicating severe pain. Pain symptom severity and extent will be compared between treatment groups over time.
Baseline, Week 4, Week 8, Month 3, Month 5
Change in Somatic Symptom Score Over Time
Time Frame: Baseline, Week 4, Week 8, Month 3, Month 5
Somatic symptoms will be assessed using a modified version of the Pennebaker Inventory of Limbic Languidness (PILL), which assesses the frequency of common physical symptoms and sensations. Each item is scored on a 0-10 scale where 0 indicates no problems. Number of moderate to severe somatic symptoms (scores ≥ 4) will be compared between groups.
Baseline, Week 4, Week 8, Month 3, Month 5
Change in Depressive Symptom Score Over Time
Time Frame: Baseline, Week 4, Week 8, Month 3, Month 5
The Patient-Reported Outcomes Measurement Information System (PROMIS) Depression Short Form 8b is an 8-item scale developed to assess depression in individuals 18 and older. Each item is rated on a five-point scale. For this study, response options are slightly altered for greater consistency across measures and precision in response levels (i.e., 1 = "never" is changed to none of the time and 5 = "always" is changed to "all or almost all of the time."). Items are summed to provide a total severity score (range = 8-40), with higher scores indicating greater severity of depression. Depressive symptom severity will be compared between treatment groups over time.
Baseline, Week 4, Week 8, Month 3, Month 5
