Psychoneurometric assessment of dispositional liabilities for suicidal behavior: phenotypic and etiological associations

Background Can core genetic liabilities for suicidal behavior be indexed using psychological and neural indicators combined? The current work addressed this question by examining phenotypic and genetic associations of two biobehavioral traits, threat sensitivity (THT) and disinhibition (DIS) – operationalized as psychoneurometric variables (i.e., composites of psychological-scale and neurophysiological measures) – with suicidal behaviors in a...
