Just-In-Time Adaptive Interventions for Addictive Behaviors

Summary

Background:

Many smartphone apps intend to help people with addictions. But not enough is known about how they should work. Researchers want to study an app that gives people the advice they need, just when they need it. This is a Just-In-Time Adaptive Intervention (JITAI). To create a good JITAI, researchers need to know what approaches work best at different moments.

Objective:

To develop ways to treat addiction with a smartphone app.

Eligibility:

Adults ages 18-75 who use heroin or other opioids

Design:

Participants will be screened in another protocol.

Participants will visit a Baltimore clinic 3 days a week to give urine and breath samples.

Some participants will get their treatment at this clinic.

Participants will answer questions about their personality and stress.

Participants will randomly be assigned to the JITAI group or a comparison group.

Participants will have a training session on using the smartphone app. JITAI participants will also watch a video about the written messages they will see in the app.

Weeks 3-10: Participants will carry a smartphone. Four times a day, it will beep and ask questions. These will be about the participants' activities and mood. The JITAI group will see a short message after. The message is meant to be helpful.

For the first 16 evenings, JITAI participants will get more information on the phone.

Answers to the app's questions will be transferred automatically from the smartphone to secure computers at the NIH.

During the last week, participants can choose the kind of messages they see.

Week 11: participants will return the smartphone and answer questions.

Weeks 12-16, participants who are getting their medicine from the research clinic will be encouraged to transfer to other clinics. Otherwise, they will have their dose slowly reduced to zero.

Interventions

OTHER

Formative Interviews (not an intervention)

One hour formative-interview session

BEHAVIORAL

Cognitive-behavioral therapy (CBT)

In CBT, negative emotional states are viewed as problems to be solved, and the client learns skills to solve them.

BEHAVIORAL

Acceptance and commitment therapy (ACT)

In ACT, negative emotional states are viewed as a necessary and potentially valuable component of a full life. When they occur, the goal is not to solve them, but to experience them in an observant, curious, nonjudgmental way-a practice referred to as mindfulness.
