abstract="OBJECTIVE: Previous research suggests that sleep disturbance is associated with suicidal ideation and suicide attempt. However, few studies have accounted for the  presence of multiple mental disorders and interpersonal factors associated with  suicide risk. Furthermore, limited research has examined which aspects of sleep  disturbance are most strongly associated with suicidal thoughts and attempts. <br><br>METHOD: A large community-based sample of Australian adults (n = 3,618; 81% female;  37% reporting ideation) completed a comprehensive survey assessing suicidal thoughts  and behaviours, sleep disturbance, common mental disorders and interpersonal risk  factors. Sleep disturbance was assessed using the 6-item PROMIS sleep disturbance  scale and suicidality was measured using the Psychiatric Symptom Frequency Scale. Analyses were adjusted for age, sex, perceived burdensomeness, thwarted  belongingness, and clinical caseness for six mental disorders, including major  depression. <br><br>RESULTS: After accounting for mental health, demographic and  interpersonal characteristics, increasing sleep disturbance was significantly  associated with higher odds of both suicidal ideation (OR=1.17 for one-SD increase  in PROMIS-SD), and suicide attempt (OR=1.33 for one-SD increase in PROMIS-SD). Of  the specific indicators of sleep disturbance, only sleep onset (difficulties falling  asleep) had a significant independent association with both suicidal ideation  (p < 0.001) and suicide attempt (p = 0.047). <br><br>CONCLUSIONS: Sleep disturbance is  independently associated with greater risk of suicidal thoughts and behaviours. Sleep disturbance is highly modifiable, so sleep interventions for people with  suicide risk and sleep problems may provide an effective and efficient approach to  suicide prevention in the community.<p /> <p>Language: en</p>",
