Table denotes unstandardized β weights for predictors. Bold values indicate p < .05 significant effects. 95% CI = 95% confidence intervals for each predictor. σ ² represents Level 1 variance (within person), τ ₀₀ represents Level 2 variance (between person). Day of the week is coded as 0 = weekday, 1 = weekend. Gender is coded as 0 = male, 1 = female.
