Better sleep quality and longer sleep duration are associated with fewer depressive symptoms and greater well-being among Kuwait University students, independent of item overlap.

In a cross-sectional study of 389 Kuwait University students, better sleep quality (B = -1.22, 95% CI -1.84 to -0.60; β = -0.20) and longer sleep duration (B = -0.48, 95% CI -0.74 to -0.21; β = -0.17) were associated with lower depressive symptoms. Better sleep quality (B = 4.01, 95% CI 1.72 to 6.30; β = 0.19) and longer duration (B = 1.35, 95% CI 0.37 to 2.33; β = 0.14) were associated with higher well-being.

Better sleep quality and longer sleep duration are associated with fewer depressive symptoms and greater well-being among Kuwait University students, independent of item overlap. The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 34/100 (low).

The Claim

Better sleep quality and longer sleep duration are associated with fewer depressive symptoms and greater well-being among Kuwait University students, independent of item overlap.

This conclusion is most relevant to: 389 Kuwait University students recruited by convenience from a campus-based physical-assessment study.

What the Research Shows

The conclusion draws on 1 linked study. Highlights from the cited literature:

  • Sleep Characteristics and Mental Health Among Kuwait University Students: Sensitivity Analyses for Item Overlap. (Behavioral sciences (Basel, Switzerland), 2026) —

How It Works

The proposed biological pathway:

  • Sleep quality and duration are assessed via self-report
  • Depressive symptoms and well-being are measured using validated scales
  • Multivariable linear regression adjusts for covariates and item overlap
  • Better sleep quality and longer duration are associated with better mental health

Who Might Benefit

Evidence fit by population:

  • 389 Kuwait University students recruited by convenience from a campus-based physical-assessment study

Limitations & Caveats

Important context when interpreting this evidence:

  • Cross-sectional design prevents causal inference
  • Convenience sampling may limit generalizability
  • Self-reported sleep measures may be subject to recall bias
  • Sleep latency was not robust to item-3 removal, suggesting potential overlap effects

Frequently Asked Questions

What sleep characteristics were associated with depressive symptoms?

Better sleep quality and longer sleep duration were associated with fewer depressive symptoms, while more frequent sleep disturbance and longer sleep latency were associated with more depressive symptoms.

Did the study find any sex differences?

No statistically significant sleep-by-sex interactions were detected.

What was the sample size and population?

The study included 389 Kuwait University students, recruited by convenience from a campus-based physical-assessment study.

What was the study design?

This was a cross-sectional study using questionnaire data and multivariable linear regression with sequential covariate adjustment.
