Smartphone-based Intervention for Young Adults With ADHD

Training Inhibitory Control Using Personalized Strategies (TIPS): A Randomized Controlled Feasibility Trial of a Smartphone-Based Intervention for Alcohol Use in Young Adults With ADHD

The primary goal of this clinical trial is to test if a smartphone-based intervention is feasible & acceptable among young adults with ADHD who also engage in risky drinking behaviors. A secondary aim is to test preliminary intervention efficacy. The main questions it aims to answer are:

Is the smartphone intervention feasible & acceptable for participants (e.g., are they responding regularly, is there a low level of burden reported)?

Does the smartphone intervention improve symptom awareness, inhibitory control, and problematic alcohol use?

Participants will:

Attend a virtual baseline visit to assess ADHD, alcohol use, and other life experiences.

Complete either the TIPS smartphone intervention or a control smartphone protocol over the course of 31-days, starting the first Friday after the baseline visit.

Attend a virtual follow-up visit, where many of the same questions from the baseline visit will be asked again.
