Prolonged Exposure Therapy for PTSD
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests Prolonged Exposure Therapy to determine if the time of day influences its effectiveness in reducing trauma-related fears in individuals with PTSD (Posttraumatic Stress Disorder). Participants will attend therapy sessions either in the early morning or late afternoon and will complete related exercises at home during these times. The trial aims to discover whether morning or afternoon sessions more effectively reduce PTSD symptoms. It suits individuals with PTSD who are interested in this therapy and can attend sessions at the designated times. As an unphased trial, it provides a unique opportunity to explore personalized therapy timing for PTSD relief.
Do I have to stop taking my current medications for the trial?
You don't have to stop taking your current medications, but any non-exclusionary psychotropic medications must be stable for at least 3 weeks before starting the trial and should remain stable throughout your participation.
What prior data suggests that Prolonged Exposure Therapy for PTSD is safe?
Research has shown that Prolonged Exposure Therapy (PE) is a well-accepted treatment for PTSD. Studies have found that it not only reduces PTSD symptoms but is also generally safe for participants. For example, a large study with 916 veterans demonstrated significant improvements in PTSD symptoms, highlighting both its effectiveness and safety.
PE therapy involves revisiting trauma-related memories in a controlled setting to gradually lessen distress. This method has been tested in many studies, and most participants manage it well. While some people might experience temporary discomfort during sessions, these feelings are usually mild and manageable.
Overall, the consistent use of PE in various studies and its recognition as an effective PTSD treatment suggest that it is a safe option for most people seeking help for PTSD.12345Why are researchers excited about this trial?
Researchers are excited about Prolonged Exposure (PE) Therapy for PTSD because it explores the impact of session timing on treatment effectiveness. Unlike traditional therapy sessions that don’t typically consider the time of day, this trial is testing whether participating in therapy during early mornings or late afternoons can influence outcomes. By understanding how timing affects therapy benefits, this study could lead to more personalized, effective treatment schedules for individuals with PTSD.
What evidence suggests that Prolonged Exposure Therapy is effective for PTSD?
Research has shown that Prolonged Exposure Therapy (PE) effectively treats PTSD. A small initial study found that PE significantly reduced PTSD symptoms, with improvements lasting at least six months. Another study discovered that both 60-minute and 90-minute PE sessions effectively reduced PTSD symptoms. Additionally, PE has proven effective for various groups, including adults who have experienced trauma from events like sexual assault. In this trial, participants will be randomized to receive PE sessions either in the early morning or late afternoon. Studies have shown that PE, regardless of the time of day, significantly decreases the severity of PTSD symptoms. Overall, PE has a strong history of helping people with PTSD feel better.56789
