Electrodermal activity (EDA) and suicidal behavior.
There may be a connection between suicidal tendencies, electrodermal activity (EDA), disorders of impulse control, and neurobiochemistry (in the sense of a "psychobiology of suicidal tendencies"). The EDA values obtained during a psychobiological habituation experiment involving 11 female patients with personality disorders (PA; ICD-10) and histories of suicide attempts were compared with those of age-paralleled nonsuicidal depressive patients and depressive patients with histories of suicide attempts. They were also compared with EDA values in female schizophrenics with and without histories of suicide attempts. The PA group showed significant differences in all EDA values compared with nonsuicidal depressives, but no significant differences compared with other groups.
