consider depression levels as measured by the WHO-5. Focusing only on the EBCT group for this question (i.e., you need to select only the people in this group for analysis), perform the appropriate statistical test to see if there is a significant difference in the WHO-5 score, before versus after treatment. Did depression decrease (i.e., wellbeing increase) after treatment?

report the mean difference in WHO-5 score between before versus after treatment (including whether there was an increase/decrease), and the results of the test including a stat block and effect size.
