 Participation in this study will last 20 weeks, with follow-up visits occurring 4 and 8 months after starting. Participants will be randomly assigned to receive either an individualized therapy for depression and anxiety, called interpersonal psychotherapy for depression with panic and anxiety symptoms IPT-PS, or a standard therapy for depression, called brief supportive psychotherapy BSP. All participants will complete up to 16 therapy sessions and receive a standard SSRI treatment with the medication citalopram hydrobromide. During the IPT-PS treatment, a study therapist will examine regular computer updates of depression and anxiety scores for participants and talk to them about identifying and addressing life stressors that trigger symptoms. During the BSP treatment, a study therapist will encourage participants to arrive at their own solutions by emphasizing the participants strengths and examining what has worked in the past.
