In a new study, the investigators examine the impact of
cognitive behavior therapy (CBT) for depression in a group of children ages 7
to 17 years. Half of the children will receive CBT, and the other half will get
“supportive treatment” (i.e., they will spend time talking to the therapist
about whatever they want). The investigators are interested in how well the
treatment affects depressive symptoms and quality of life. What are the
independent and dependent variables in this investigation?
