  1. n = 123. Regression coefficients of the final model, after step 5, are presented. B refers to the unstandardized regression coefficients, β to the standardized regression coefficients.
  2. Significant effects are highlighted in bold.
  3. Cortisol response was computed as difference (post–pre) in cortisol concentrations between T2 and T4.
  4. aConfidence intervals and standard errors for the unstandardized regression coefficients were derived by bias-corrected and accelerated bootstrapping with 1500 iterations.
