Plain-language summary

Mental contamination-an internal experience of dirtiness evoked in the absence of physical contact with an external source-has been linked to the development and maintenance of posttraumatic stress disorder (PTSD) following exposure to sexual abuse or assault (Adams et al., 2014; Badour et al., 2013; Brake et al., 2017). Mental contamination has been associated with greater PTSD severity (Rachman et al., 2015) and higher elevations in specific PTSD symptom clusters (particularly those of intrusive re-experiencing, negative cognitions/mood, and arousal/reactivity; Brake et al., 2019; Fergus \& Bardeen, 2016). Additionally, trauma-related mental contamination has been linked to a number of negative posttraumatic emotions such as shame, guilt, disgust, and anger (Fairbrother \& Rachman, 2004; Radomsky \& Elliott, 2009). Despite clear and consistent links between mental contamination and problematic posttraumatic outcomes following sexual trauma, there is a dearth of research investigating how existing or promising new interventions for PTSD impact mental contamination. Written Exposure Therapy (WET) is a five-session treatment for PTSD that was designed to be both brief and easy to administer (Sloan et al., 2012). According to Sloan and colleagues' (2012) protocol, sessions broadly involve 30-minute exposures in which the patient writes about the events of their trauma in detail, followed by 10 minutes of discussing the exposure with the therapist. This treatment protocol has minimal therapist involvement, no homework assignments, and shorter treatment sessions. Research shows that WET is efficacious among different samples (e.g., survivors of motor vehicle accidents and combat veterans), has low dropout rates, treatment satisfaction is high, and the gains seen by participants after completion are maintained at follow-up (Sloan et al., 2012, 2013, 2018; Thompson-Hollands et al., 2018, 2019). Given these factors, WET has the potential to be a useful intervention in reducing symptoms of PTSD among a sample of survivors of sexual trauma. Given its relevance to this trauma population, a test of this intervention for its impact on reducing trauma-related mental contamination is also needed. The current study will use Single Case Experimental Design to isolate and evaluate the effects of WET in reducing both PTSD symptoms and trauma-related mental contamination among individuals with PTSD resulting from sexual trauma. Aims: Explore whether participants demonstrate reductions in mental contamination and PTSD symptoms in response to 5 sessions of WET. Visual inspection analysis and statistical methods will be used to draw conclusions regarding the effects of the interventions on PTSD symptoms and mental contamination.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * individuals with a history of sexual trauma meeting past-month diagnostic criteria for PTSD (meeting diagnostic status on the DIAMOND and score greater than or equal to 33 on the PCL-5) * individuals reporting current experiences of trauma-related mental contamination (greater than or equal to 30 on the PEMC and endorsement of current mental contamination at the time of the intake assessment) * 18 years of age or older * fluent in English (including being able to read and write in English) * patients on psychotropic medications will be included if they have been maintained on a stable dose for at least 4 weeks prior to beginning the study and are willing to maintain a stable dosage throughout the study period; this procedure allows for a broader range of participants and avoids having outcomes assessment confounded by the initiation of medication during treatment * patients must be willing to refrain from additional trauma-related treatment for the duration of the study. Exclusion Criteria: * We will exclude individuals diagnosed with psychological conditions that may be better addressed by alternative treatments; these conditions may include: * any history of psychotic disorders or dissociative identity disorder * manic episodes endorsed in the past year * current anorexia nervosa * imminent risk of suicide (i.e., intent/plan) * severe substance use disorders. * We will also exclude individuals who endorse factors for which the treatment being studie…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
