Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Additionally, the investigators will compare the effectiveness of sending messages on a random schedule (using a micro-randomized trial design) or sent by a reinforcement learning policy on overall change in depression and anxiety symptoms and daily mood during the 8-week study.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Participants will be randomized to:
1. a uniform random messaging group (micro-randomized trial design).
2. a reinforcement learning group with a learned decision mechanism for the timing and type of text-message. The algorithm learns from previous data (which messages were sent, what was the participants' mood) to maximize an increase in participants mood. No other data are collected from participants' phones.
The investigators will compare the effect of sending text-messages by a random schedule, and text-messaging chosen by the RL algorithm. This allows to both evaluate the effect of the individual intervention components over time within a micro-randomized trial design, and assess the added value of using RL to adapt the messaging scheme.
The investigators hypothesize that:
* Participant will show improvements in depression, anxiety symptoms and mood during the 60 day study.
* The participants in the group receiving reinforcement learning will have a greater improvement in depressive symptoms, anxiety and positive mood during the study than participants in the micro-randomized group.
* The investigators will find differential effects on mood ratings for the two categories of messages

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Uniform Random
Participants will receive supportive text-messages for a period of 2 months. These text-messages have two categories: behavioral activation (BA) and coping skills. In this arm, participants will receive one of these types of messages daily on a random schedule in random time periods throughout the day.
Uniform random message delivery
In this arm, the categories and timings of text-messages will be delivered to participants using a random schedule
Reinforcement Learning
In this arm we will test a reinforcement learning (RL) algorithm with a learned decision mechanism for the timing and type of text-messages. The algorithm learns from previous data (which messages were sent, what was the participants' mood) to maximize an increase in participants' mood.
Reinforcement learning message delivery
In this arm, the categories and timings of text-messages will be chosen by a reinforcement learning algorithm
Mood ratings only
In this arm, participants will monitor their mood and receive random feedback based on mood responses.
Mood ratings only
In this arm, participants will monitor their mood daily and receive feedback on that mood randomly
