Suicidal behaviour during different phases of bipolar disorder.
BACKGROUND
There are no previous studies comparing the prevalence and risk factors for suicidal behaviour during different phases of bipolar disorder.


METHODS
In the Jorvi Bipolar Study (JoBS), 1630 psychiatric in- and outpatients were screened for bipolar disorders with the Mood Disorder Questionnaire. Using SCID I and II interviews, 191 patients were diagnosed with bipolar disorders (90 bipolar I, 101 bipolar II). Suicidal ideation was measured using the Scale for Suicidal Ideation (SSI). Prevalence and risk factors for ideation and attempts during different phases (depressive, mixed, depressive mixed and hypomanic/manic phases) were investigated.


RESULTS
There were marked differences between phases regarding suicide attempts and level of suicidal ideation. Hopelessness predicted suicidal behaviour during the depressive phase, whereas a subjective rating of severity of depression and younger age predicted suicide attempts during mixed phases.


CONCLUSIONS
The relatively small sample size in some phases.


CONCLUSIONS
Suicidal behaviour varied markedly between different phases of BD. Suicide attempts and suicidal ideation were related to phases which are associated with depressive aspects of the illness. Hopelessness and severity of depression were key indicators of risk in all phases.
