Reward Responsiveness in Suicide Attempters: An Electroencephalography/Event-Related Potential Study.

ABSTRACT:

Background

The present study aimed to objectively examine the Research Domain Criteria (RDoC) subconstructs of reward anticipation and initial response to reward in adult suicide attempters, compared with nonattempters, using electroencephalography (EEG) and event-related potentials (ERPs) within the context of the RDoC-recommended experimental paradigms for these subconstructs.

Methods

Participants had either a history of at least 1 suicide attempt (n = 30) or no history of attempting suicide (n = 30). They completed diagnostic interviews, self-report questionnaires, and 2 computer-based tasks-the monetary incentive delay task and the doors task-during which continuous EEG was recorded. Temporospatial principal component analysis was used to isolate each of the ERP componen
