Lifetime rhythmicity and mania as correlates of suicidal ideation and attempts in mood disorders.

Full Abstract

BACKGROUND:
The aim of this study is to establish to what degree variation in lifetime experience of rhythmicity and manic-hypomanic features correlates with suicidality in individuals with mood disorders and other major psychiatric diagnoses and in a comparison group of controls.

METHOD:
Suicidal ideation and attempts were investigated in a clinical sample, including 77 patients with schizophrenia, 60 with borderline personality disorder, 61 with bipolar disorder, 88 with unipolar depression, and 57 with panic disorder, and in a comparison group of 102 controls. Using information derived from the diagnostic interview and a self-report assessment of mood spectrum symptoms, subjects were assigned to 3 categories according to the maximum level of suicidality achieved in the lifetime (none, ideation/plans, and suicide attempts). The association of categorical and continuous variables with suicidality levels was investigated using multinomial logistic regression models.

RESULTS:
Suicidal ideation and plans were more common in unipolar depression (50%) and bipolar disorder (42.4%) than in borderline personality disorder (30%), whereas the reverse was true for suicidal attempts. In each of the study groups, the number and the type of mood spectrum items endorsed, including depressive and manic-hypomanic items and rhythmicity and vegetative symptoms, were associated with increased levels of suicidality.

CONCLUSIONS:
Our results suggest that the assessment of lifetime rhythmicity and manic-hypomanic features may be clinically useful to identify potential suicide attempters in high-risk groups.
