Note: Results refer to the 3 regression linear models with DASS stress, DASS depression and DASS anxiety as dependent variables, linked to ANCOVA model. Covariates in the model are MAAS, Brief-COPE Avoidant and Brief-COPE Approach. To obtain the group means (ª), covariates are evaluated on the following values: MAAS = 61.16, Brief-COPE Avoidant = 26.15, Brief-COPE Approach = 35.40. Confidence intervals at 95% are obtained with bootstrap standard errors with 500 resamples. T-tests are evaluated at 5% (*p<.05), 1% (**p<.01), and 0.1% (***p<.001).
