Borderline personality disorder	−.09	−.10	−.09	.41*
Diagnostic factors:
Internalizing factor	−.19*	−.16*	−.19*	.65*
Internalizing factor	.00	.01	−.01	.15*
ERP Response variable
Target P3 amplitude	—	.55**	.29**	−.37*

Note. DIS/ERP Factor = scores on factor reflecting variance in common among two self-report measures of disinhibition proneness (total score on a 100-item version of the Externalizing Spectrum Inventory; Aggression subscale of the Multidimensional Personality Questionnaire-brief form) and two event-related potential measures (Novel P3 = amplitude of P3 response to novel pictures in a three-stimulus visual oddball task; Probe P3 = amplitude of P3 response to unwarned noise probes during a picture-viewing task). Target P3 = amplitude of P3 response to target stimuli in a three-stimulus visual oddball task. Axis I = DSM-IV clinical disorder diagnoses; Axis II = DSM-IV personality disorder diagnoses. Externalizing factor = scores on a factor reflecting variance in common among diagnostic symptom counts for alcohol abuse/dependence, drug abuse/dependence, conduct disorder, and adult antisocial behavior. Internalizing factor = scores on a factor reflecting variance in common among diagnostic symptom counts for major depression, generalized anxiety disorder, social phobia, and specific phobia. Bolded font entries are significant at p < .001.
