Home-Delivered Attention Control Treatment for Post Traumatic Stress Disorder (PTSD)
- Conditions
- PTSD
- Registration Number
- NCT04228133
- Lead Sponsor
- Tel Aviv University
- Brief Summary
The aim of the study is to explore the efficacy of home-delivered Attention Control Training (ACT) for Posttraumatic Stress Disorder (PTSD).
Three randomized controlled trials have shown that attention bias modification protocols applying attention control training (ACT) aimed to balance attention between threat-related and neutral stimuli are efficient in reducing PTSD symptoms. However, contrary to in-clinic administration, such as applied in the above mentioned studies, home-delivered attention bias modification was not effective in reducing symptoms among treatment-seeking patients.
It is crucial to continue examining the efficacy of home-delivered ACT as PTSD entails functional impairments that might impede treatment-seeking patients from reaching to clinics to receive treatment. This could also inform other ABM protocols designated to treat other disorders.
- Detailed Description
The aim of the study is to explore the efficacy of home-delivered Attention Control Training (ACT) for Posttraumatic Stress Disorder (PTSD).
Three randomized controlled trials have shown that attention bias modification (ABM) protocols applying attention control training (ACT) aimed to balance attention between threat-related and neutral stimuli are efficient in reducing PTSD symptoms. However, contrary to in-clinic administration, such as applied in the above mentioned studies, home-delivered ABM was not effective in reducing symptoms among treatment-seeking patients.
It is crucial to continue examining the efficacy of home-delivered ACT as PTSD entails functional impairments that might impede treatment-seeking patients from reaching to clinics to receive treatment. This could also inform other ABM protocols designated to treat other disorders.
To overcome some critical differences between home and lab environments, the investigators developed a home-delivered ACT protocol that resembles as much as possible the typical-in-lab protocol. Specifically, participants will be accompanied during their training sessions using internet-based video conference, permitting a better control for the physical environment before and during the session and a direct interaction with the experimenters.
To test its efficacy, the investigators will recruit participants that are diagnosed with PTSD and will be randomly assigned to one of two home-delivered conditions: ACT and a control ABM condition. It is hypothesized that home-delivered ACT will produce greater reduction in PTSD symptoms relative to a control ABM protocol. It is also expected that ACT will reduce attention bias variability to a greater extent compared to the control condition.

Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- PARALLEL
- Primary Outcome Measures
Name Time Method Change from baseline of the total severity score of the CAPS-5 interview up to 2 weeks pre-treatment and 1-2 weeks post-treatment The Clinician Administered PTSD Scale (CAPS-5), is a structured interview that will be used to make a diagnosis of PTSD according to the DSM-V criteria. This interview is consists of 30 items regarding the frequency and intensity of PTSD symptoms and a total score of severity is been rated, with higher scores denoting higher symptom severity.
- Secondary Outcome Measures
Name Time Method Change from baseline of the total score of the PTSD Checklist (PCL-5) up to 2 weeks pre-treatment and 1-2 weeks post-treatment The PCL-5, is a 20-item National Center for PTSD Checklist of the Department of Veterans Affairs. Scores can range from 0 to 80, with higher scores reflecting more symptoms of PTSD.
