Sensitivity analyses showed that excluding days with alcohol or cannabis use did not change the model structure, though the effect of daily stress on sleep duration became marginally significant ( p = 0.057).

In the extended model including additional covariates, the association of daily stress was no longer significant ( b = 0.00, SE = 0.00, p = 0.216), whereas average stress showed a trend for a significant association with longer SOL ( b = 0.01, SE = 0.01, p = 0.074).
