ReNeuWell mental well-being app: protocol for a randomised controlled trial.

Area of Science:

• Digital mental health
• Psychology
• Mobile health interventions

Background:

• A research-to-retail gap exists in mental well-being apps, with many not publicly available or tested.
• Few apps offer multicomponent interventions, despite their proven efficacy.
• ReNeuWell addresses this by offering a validated measure and personalized activities.

Purpose of the Study:

• To describe the protocol for a randomized controlled trial (RCT) of the ReNeuWell app.
• To test the efficacy of ReNeuWell in improving mental well-being in general adult users.
• To compare ReNeuWell users against an active control group.

Main Methods:

• A preregistered RCT recruiting general population iPhone users from the Apple App Store.
• Participants are randomized to ReNeuWell or an active control app.
• Outcomes measured via in-app surveys at weeks 1, 6, and 12, analyzed with linear mixed models.

Main Results:

• Hypothesized that ReNeuWell users will show significant increases in mental well-being.
• Hypothesized that ReNeuWell users will show significant decreases in mental distress.
• Trial outcomes will be published in peer-reviewed literature and on the registry website.

Conclusions:

• ReNeuWell is a novel iPhone app designed to measure and improve mental well-being.
• The study protocol outlines a rigorous RCT to evaluate its effectiveness.
• Findings will contribute to understanding digital interventions for mental well-being.
