The bimodal P300 oddball component is decreased in patients with an adjustment disorder: An event-related potentials study.

Objective: We found previously that use of a bimodal oddball design with synchronized pairs of audio-visual stimuli increased the sensitivity of the P300 wave to detect subclinical anxiety-depression in otherwise healthy subjects. Here, we wished to determine whether these P300 modulations would also be encountered when a clinical population comprised of patients with an adjustment disorder (AJD) was compared to healthy controls.

Method: Two groups, each comprised of twenty-five participants (AJD patients, and controls; N=50) had to detect deviant stimuli among frequent stimuli in an oddball task by clicking on a button.
