We invite you to participate in the TREE-Connect Study. 
   
This study aims to develop a hybrid intervention that combines a remote psychotherapy with a novel mobile health app (TREE-Connect). Together, this combined intervention can lead to improvement in depression and social connectedness in mid- and late-life. 
   
Participants will be randomized to one of two groups, each consisting of 9 weekly therapy sessions. Randomization is like flipping a coin and there is a 50/50 chance of being assigned to either group.
   
One group will be treated with 9 face-to-face video sessions of Engage & Connect, a psychotherapy aimed to increase engagement in rewarding social activities. The other group will receive 9 sessions of hybrid TREE-Connect app + video delivered psychotherapy (5 face-to-face video sessions and 4 app sessions).
   
The study also include 4 research assessments via video with questions about mood, thoughts and physical health. Participants will also track their activity levels using a wearable watch. We will invite interested participants to optional MRI scans. 

Total study participation is approximately 9 weeks.
