Home-Delivered Attention Control Treatment for Post Traumatic Stress Disorder (PTSD)

PTSD Clinical Trial

Official title: Home-Delivered Attention Control Training for Post Traumatic Stress Disorder: A Randomized Controlled Trial

Status Completed

Clinical Trial 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.

Clinical Trial 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. ;
