Summary

The purpose of this study is to determine whether a computerized intervention designed to change the nature of attention biases will be effective in reducing the symptoms of post traumatic stress disorder (PTSD) in American combat veterans returning from the wars in Afghanistan and Iraq.

Conditions

  • Stress Disorders, Post-traumatic

Interventions

BEHAVIORAL

Attention Bias Modification (ABM)

The ABM comprised a probe detection paradigm described above, modified to facilitate the allocation of attention away from threatening material. In this task, the probe always replaced the neutral word. Stimuli comprised a different set of 12 threat-neutral word pairs different than those used in the attention bias assessment. Participants completed 288 training trials: 2 (probe type) x 2 (probe location) x 2 (threat location) x 12 (threat-neutral word pairs) x 3 (repetition). Thus, although there were no explicit instructions to direct attention away from threat words, on all trials, the position of the neutral word indicated the position of the probe.

BEHAVIORAL

Attention Control Condition (ACC)

The ACC condition was identical to the ABM procedure with the exception that the probe appeared with equal frequency in the position of the threat and neutral words, such that attention was neither trained towards nor away from threat.
