The staff at a mental health clinic wants to determine if their current form of short-term therapy substantially reduces depression. Prior to the first treatment, each patient will be asked to complete the Acme Depression Inventory (ADI), which renders a score from 0 to 75 (0 = Low depression . . . 75 = High depression). Patients will be asked to complete the same instrument at the conclusion of their appointment on Week 5 and at the end of their final appointment on Week 10.
