Background:
Although nonsuicidal self-injury (NSSI) is known to be associated with increased risk of death by suicide and suicide attempts, minimal research has focused on comparing recent suicide attempters with and without NSSI on suicide attempt characteristics (frequency and severity of suicide attempts). Understanding how NSSI impacts suicide attempt characteristics can help providers to enhance their assessment and treatment strategies so as to prevent future suicidal behaviors.
Aims:
The present study investigated the extent to which a history of NSSI was related to the frequency and severity of suicide attempts in a sample of recent suicide attempters.
Method:
Participants included 171 adult patients who presented to the hospital within 24 hr of a suicide attempt. Information about their suicide attempts and NSSI was gathered using self-report questionnaires and interviews.
Results:
Suicide attempters with a history of NSSI reported significantly more suicide attempts and more suicide attempts requiring medical attention, after controlling for important clinical covariates.
Conclusion:
NSSI was uniquely associated with suicide attempt characteristics, highlighting the importance of NSSI in suicide assessment, prevention, and treatment efforts.
