Home-Delivered Attention Control Training for Post Traumatic Stress Disorder: A Randomized Controlled Trial
In Brief
A clinical study evaluating Attention Control Training (ACT) and Attention Bias Modification (ABM) for PTSD. Completed, enrolled 60 participants across 1 site.
Detailed 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.
Study Details
Timeline
Interventions
A home-delivered version of ACT will be administered in this study. ACT will be comprised of 8 sessions with a variation of the dot-probe task in which the target probe replaces the neutral and threat stimuli with an equal probability to reduce attention bias variability (ABV). In addition, sessions will include video conference with the experimenter. This condition has found to be more effective in PTSD symptom reduction compared to ABM.
A home-delivered version of ABM will be administered in this study. ABM will be comprised of 8 sessions with a variation of the dot-probe task in which the target probe always replaces the threat stimuli to induce diversion of attention away from threat. In addition, sessions will include video conference with the experimenter. This condition has found to be have an inferior effect on PTSD symptom reduction compared to ACT, and thus, this ABM condition has been chosen as a control condition.
