Abstract
Objective
Serotonergic (5‐HT) functioning has been shown to be inversely associated with intentional self‐injurious behaviors. The purpose of this study was to examine the association between three related self‐report measures of intentional self‐injurious behaviors (suicidal thoughts/behavior, history of nonsuicidal self‐injury, history of severe self‐harm when angry) and a putative electrophysiological index of 5‐HT activity, the loudness dependence of auditory evoked potential (LDAEP).
Method
Auditory evoked potentials were recorded from 41 men (mean age = 20.69, standard deviation [SD] = 2.98) during the administration of various tone loudness stimuli, followed by completion of the self‐report measures.
Results
The component slope was associated with all measures of self‐injurious behavior in the expected direction.
Conclusion
The LDAEP has the potential to be used as a noninvasive index of intentional self‐harm disposition. Additional studies are needed using other populations, including women and treatment‐seeking individuals, to determine if the LDAEP more broadly discriminates risk of self‐injuring.
