研究概览
简要总结
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.
详细描述
This is a pilot study to investigate the neuroscience of a single-session psychosocial intervention for depression symptoms. Brain activity is measured with EEG in both research participant and therapist. Participants will fill in questionnaires about their depression symptoms and experience during the psychosocial intervention.

盲法说明
The research assistants and personnel will be aware of the randomized intervention for each participant since this will be stored on an encrypted spreadsheet with a password. The participants will be made aware that they will be randomized to a group, however, they will not know what intervention they have been assigned to.

结局指标
主要结局
Inter-brain phase synchronization in Alpha frequency band via Phase Locking Value
时间窗: During the interventional session, approximately 60 minutes
Inter-brain synchronization will be calculated for the Alpha frequency band via phase locking value during the interventional session for both study arms and will be used to assess any potential differences in Alpha frequency inter-brain synchronization between groups
Inter-brain phase synchronization in Theta frequency band via Phase Locking Value
时间窗: During the interventional session, approximately 60 minutes
Inter-brain synchronization will be calculated for the theta frequency band via phase locking value during the interventional session for both study arms and will be used to assess any potential differences in Theta frequency inter-brain synchronization between groups
次要结局
- Directed inter-brain connectivity in theta frequency band via Granger Causality(During the intervention session, approximately 60 minutes)
- Directed inter-brain connectivity in the Alpha frequency band via Granger Causality(During the intervention session, approximately 60 minutes)
- Correlation between Inter-brain Phase Synchronization in Alpha frequency band via phase locking value and change in depression symptoms via Beck Depression Inventory II (BDI) total score(Baseline Up to 4 weeks post-intervention session)
