Table 2: Two-way mixed analyses results for all measures of the study. Figure 2: Emotion Regulation and mental health measures with significant group \(\times\) time interactions or main effects of time for Emotional Control (**A**), Rumination (**B**), Anxiety Symptoms (**C**), Depressive Symptoms (**D**), Internalizing Symptoms (**E**) and Self-Efficacy (**F**). Cognitive measures: Mixed ANOVA analyses did not show statistically significant interactions between group and assessment time in any of the cognitive function's measures. On the other hand, statistically significant main effects of time were found on measures of cognitive flexibility (such as total errors, or perseverative responses and errors), as assessed by the WCST, simple selective attention, as assessed by the SCWT Colors subtest and TMT-A, as well as in working memory scores, as assessed by the TMT-B, and SCWT Colors and words subtest, with significant increases on cognitive performance on the both groups, from pre- to post-assessment (see Table 2). In Figure 3, the global mean T-scores from the pre-and post-assessments for each subgroup of cognitive functions assessed have been visually represented.
