About the study
The goal of this study is to learn the extent to which client-therapist brain activity may synchronize during a psychosocial intervention for depression symptoms.
The study will compare behavioral activation, a client-centered type of cognitive-behavioral therapy, to psychoeducation which delivers information on strategies to recover from depression symptoms.
Participants will answer questions about their mental and physical health, attend one psychosocial intervention session receiving either Behavioral Activation or Psychoeducation with simultaneous brain activity measurement and complete follow up surveys two weeks and one month following the intervention.
