Background: To examine the relationship between anger, impulsivity and
suicidality. Methods: Thirty psychiatric inpatients admitted for suic
idal behavior were compared with 30 nonsuicidal psychiatric inpatients
and 32 healthy controls on measures of anger, impulsivity and suicide
risk. Results: The three groups were similar on demographic variables
, but the suicidal group scored higher on the suicide risk scale, impu
lsivity scale and anger scale. Anger and impulsivity correlated signif
icantly with suicide risk. High anger and impulsivity contributed syne
rgistically to the suicide risk. Whereas anger was specific to both ps
ychiatric groups, suicidals and nonsuicidals, only impulsivity was spe
cific to the suicidal group. Conclusions: These findings may have impo
rtant implications for therapists and primary prevention workers, and
may pave the way for the recognition of risk factors and for effective
intervention in patients with a high suicide risk.
