Note. Focal parameter estimates shaded in gray; SC = social comparison; SIAS = Social Interaction Anxiety Scale; b = unstandardized regression coefficient; conf. int. = confidence (compatibility) intervals constructed using profile likelihood for b, τ, and σ and empirical parametric bootstrap for R²; for single-level models, R² is adjusted R² and confidence intervals constructed using pivots for b and σ and bias-corrected accelerated nonparametric bootstrap; SC favorability scaled as POMP scores; τ₀₀ = random effects standard deviation, σ = residual standard deviation.
