All patients admitted were referred to a psychiatrist. A clinical interview based on the Mini International Neuropsychiatric Interview (MINI) and a semi‐structured interview was conducted. Patients were asked about 'ongoing' suicidal ideation or plans for suicide.</p> </sec> <sec id="ijcp12211-sec-0005" sec-type="section"> <title>Results</title> <p>Forty‐eight percent of patients received a diagnosis of bipolar disorder (BD), major depressive disorder (MDD) or an anxiety disorder; whereas, 17.1% were diagnosed with Schizophrenia or other non‐affective psychosis. Patients with insomnia (compared to patients without insomnia) more frequently had a diagnosis of BD (23.9% vs. 12.4%) or MDD (13.3% vs. 9.5%; p<italic> </italic><<italic> </italic>0.001). Moreover, patients with insomnia less frequently had attempted suicide in the past 24 h (5.3% vs. 9.5%; p <<italic> </italic>0.05) as compared with other patients, but those patients with insomnia who attempted suicide more frequently used a violent method (64.3% vs. 23.6%; p<italic> </italic><<italic> </italic>0.01) compared to other suicide attempters.</p> </sec> <sec id="ijcp12211-sec-0006" sec-type="section"> <title>Conclusions</title> <p>Our results do not support an association between insomnia and suicidal behaviour.
