Abstract

In order to explore the psychodynamics of a previously observed association between a low concentration of the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA) in cerebrospinal fluid (CSF) and an increased tendency to suicidal behavior, blind ratings of Rorschach variables were compared between depressed and/or suicidal patients with low (less than 80 nanomoles/l) and normal (greater than 80 nanomoles/l) CSF 5-HIAA. In 14 patient pairs matched for sex, age, body height, and interview-based ratings of severity of depression, the low 5-HIAA subjects had significantly more anxiety and more hostility in the Rorschach ratings. Their anxiety tolerance was lower, and they were significantly less efficient in their handling of conflict. The results support the hypothesis that biochemical variables may be of importance for certain psychodynamic mechanisms suggested to be relevant for psychopathology, including suicidal behavior.
