The researchers tested whether a new Exposure-Based Cognitive Therapy (EBCT) would enhance treatment gains compared to standard cognitive-behavioural therapy (CBT). Grosse Holtforth et al. (2019) performed a randomised-controlled trial with adults experiencing Major Depressive Disorderparticipants were randomly assigned to receive either CBT or EBCT. Participants' level of depression was assessed using various tests at pre-treatment, post-treatment, and at a 12-month follow-up stage. You will consider two different depression measures as dependent variablesscores from the Beck Depression Inventory-II (BDI-II), and scores from the WHO-Five Well-Being Index (WHO-5). Note that a mixed experiment design was used, with treatment type which is between-participants factor, and the three depression-assessment timepoints (pre-treatment, post-treatment, and follow-up) as a within-participants factor. In real life, all six conditions would be compared in more complex factorial analyses, but you will use the tests from this course to separately consider different aspects of the data. You need analyse the following data:
