Sleep disturbances prospectively predict suicidal ideation in adults
In a prospective cohort study of 652 adults, sleep disturbance (PSQI ≥ 6) was associated with a nearly 4-fold increased odds of future suicidal ideation (OR = 3.97). This association remained significant after adjusting for depressive symptoms (OR = 1.59). Bidirectional associations were also observed.

Sleep disturbances prospectively predict suicidal ideation in adults The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 34/100 (low).
The Claim
Sleep disturbances prospectively predict suicidal ideation in adults
This conclusion is most relevant to: Adults (mean age 49.7 years) from a web survey panel and local city government officers in 2022.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Sleep Problems as Prospective Predictors of Suicidal Ideation. (Archives of suicide research : official journal of the International Academy for Suicide Research, 2026) —
How It Works
The proposed biological pathway:
- ▸Sleep disturbance (e.g., prolonged sleep latency) is assessed via PSQI
- ▸Sleep problems may impair emotional regulation and increase distress
- ▸Chronic sleep disruption may exacerbate or trigger suicidal ideation
- ▸Sleep disturbance prospectively predicts suicidal ideation
Who Might Benefit
Evidence fit by population:
- ▸Adults (mean age 49.7 years) from a web survey panel and local city government officers in 2022
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Self-reported data may introduce recall bias
- ▸Sample limited to Japanese adults from a web panel and government officers, limiting generalizability
Frequently Asked Questions
What sleep problems were most predictive of suicidal ideation?▼
The PSQI global score and sleep latency (time to fall asleep) were significant prospective predictors.
Did the association hold after controlling for depression?▼
Yes, sleep disturbance remained a significant predictor of suicidal ideation even after adjusting for depressive symptoms (OR = 1.59).
How common were sleep disturbances in this study?▼
Sleep disturbance (PSQI ≥ 6) was observed in 32.8% of participants.
What was the study design and follow-up period?▼
This was a prospective cohort study with a 3-month follow-up using cross-lagged model analyses.
