Just-In-Time Adaptive Interventions (JITAIs) in a Digital Mental Health Intervention for Middle-Aged and Older Adults With Chronic Pain
What this study is about
The purpose of this research study is to refine customized in-app notifications in order to optimize users' experience with a mobile app called Wysa for Chronic Pain. This app is designed to support people who have chronic pain and who also experience symptoms of depression and/or anxiety. This version of the app is not currently available to the public.
View original scientific description
The purpose of this research study is to refine customized in-app notifications in order to optimize users' experience with a mobile app called Wysa for Chronic Pain. This app is designed to support people who have chronic pain and who also experience symptoms of depression and/or anxiety. This version of the app is not currently available to the public. Eligible participants will be asked to download and use the Wysa for Chronic Pain study app for several weeks, and to use it as they normally would if they were not part of a research study. At the beginning and end of the study period, participants will be asked to complete brief surveys about their mood, pain, physical function, and sleep. Additionally, a few participants will be asked to share their experience with the study app at the end of the research study in a casual interview using a secure audio/video recorded call. Participating in the interview portion is optional.
Interventions
OTHER
Just-In-Time Adaptive Interventions (JITAIs)
JITAIs are digital interventions that aim to deliver support to a user when the person is most in need and receptive to the intervention. In this study, multiple JITAIs will be tested and refined through completion of an iterative series of randomized trials that are interspersed with qualitative participant interviews. The purpose of each JITAI under investigation is to improve engagement with the Wysa for Chronic Pain app.
BEHAVIORAL
Wysa for Chronic Pain
Wysa for Chronic Pain is an app-based digital mental health intervention that uses a behavioral activation framework and encourages users to work toward pain acceptance. The intervention also includes cognitive behavioral therapy, mindfulness, and sleep tools.
Primary outcome measures
Engagement
Time frame: Each JITAI has a different target engagement time interval. e.g., varying from 24 hours to 7 days.
The primary outcome for each JITAI is the between-group difference in engagement with Wysa for Chronic Pain during the JITAI's target engagement time interval. Engagement is operationalized as interaction(s) with the digital mental health intervention and is automatically captured throughout the study by the intervention's technical infrastructure. It is not self-reported.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
