Solution
Anu's research design has poor Internal Validity. This is because internal validity is about the certainty with which we can say that the independent variable (in this case, therapy) is causing the dependent variable (depression levels) to change. If Anu did not take into account whether the patients were also taking medicines or not, then it's possible that the decrease in depression levels was due to the medication, not the therapy. Therefore, the internal validity of her study is compromised.

For the following questions, please utilize the case study from Eugenia.Eugenia has developed a group at her agency for people with a depression diagnosis. The group she develops utilizes art as a medium to express the challenges and hopes participants have for managing their lives with depression and their hopes for the future. She incorporates psychotherapeutic approaches including mindfulness, CBT, etc. To register for the group, patients must have a diagnosis of clinical depression, must agree to a pre-screening, and must have an insurance that is within network for her practice.In her pre-meetings she discusses with each participant that they must commit to all 8 sessions of the group, and for any session they do not attend, they will be billed a no-show fee. Participants must show up to at least the second session if they want to continue with the group, and no new participants are able to join the group after the 2nd session. Each participant signs a contract that states they understand their commitment, and also that they understand the benefits and purpose of the group, as well as the role of the therapist.The overall purpose of the group, explained to each of them in these individual sessions, is to develop strategies to express yourself, find joy, and identify aspirations for the future. Once the group begins, Eugenia has a discussion with the group about what they want to get out of the group, and each of them shares their individual goals and aspirations for the group.For Eugenia's group above, her group would be most accurately described as a: A. Therapy group B. Support Group C. Task group D. Self-help group
