Authors' conclusion
Self-confidence mediates the relationship between executive function and depression among ICU survivors.

Main finding
As reported in the abstract
Mediation of executive function–depression effect by self-confidence
- Indirect effect of impaired executive function on depressive symptoms via diminished self-confidence (full mediation), B
- 0.45; 95% CI 0.34-0.59
- Direct effect of executive function on depression with self-confidence in model (non-significant), B
- 0.07, p = 0.18
- Correlation depressive symptoms vs diminished self-confidence, r
- 0.80, p < 0.001
- Correlation depressive symptoms vs poorer executive function, r
- 0.55, p < 0.001
- Correlation reduced self-confidence vs compromised executive function, r
- 0.62, p < 0.001
Observational data: associations, not effects.
Further findings
Associations with age and gender
- Age negatively associated with depression, self-confidence and executive function; male gender positively correlated with higher self-confidence
Model fit
- CFI
- 0.962
