Remotely Resolving Psychological Stress (Remote RePS)

Status Completed

Clinical Trial Summary

The investigators have developed a mobile app called Resolving Psychological Stress (REPS) for people with posttraumatic stress disorder (PTSD). The app will administer threat-related attention bias modification to individuals who score high on a PTSD checklist. This study will be administered remotely to individuals in the United States. The aims of the study are to explore feasibility, acceptability and usability of the app in an entirely remote study, as well as to explore the efficacy of the app at reducing attention bias and PTSD symptom severity.

Clinical Trial Description

Posttraumatic stress disorder (PTSD) is a highly disabling disorder that affects approximately 8% of the population worldwide. Threat-related attention biases represent an important mechanism that may underlie PTSD symptoms. Such attention biases predict risk for PTSD following trauma exposure, and are thought to maintain some symptoms of PTSD. Research indicates that specific forms of computerized attention bias modification (ABM) training are effective in reducing attention bias for threat. We have developed a mobile app called REPS (Resolving Psychological Stress) to administer threat-related ABM training to people with symptoms of PTSD and have tested it in a laboratory-based pilot study of 22 people with elevated PTSD symptoms. Our preliminary data indicate that the app is highly acceptable to patients and that use of the app reduces attention bias for threat and PTSD symptom severity. The proposed study will expand on this prior lab-based study to test ABM training on an app entirely remotely. Our primary aim is to examine the feasibility, acceptability and usability of remotely administered app-based ABM training and to determine the efficacy of remote app-based ABM training in reducing attention bias and PTSD symptom severity. Our secondary aim is to examine whether a personalized version of ABM training results in greater attentional bias change and anxiety reduction compared to a non-personalized ABM training. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
