REThinkEMOTIONS platform integrates the following tools that were separately tested in laboratory conditions and found effective:

  • the online REThink therapeutic video game (David, Cardos, & Matu, 2018a,b)
  • the MoodWheel app for momentary ecological assessment of mood (David & David, 2019).
  • the PsyPills app for the enhancement of self-control and emotional regulation though „psychological pills” (David & David, 2019)

The platform is developed based on the experimental-demonstrative project PN-III-P4-ID-PCE-2020-2170, awarded to Dr. Oana David by UEFSCDI. The integrated platform will be accessed by youth, parents and clinicians or researchers. The main original feature is the integration of state of the art online, mobile and gaming technologies into a unique platform that allows easy access to personalized, accessible and validated prevention.

The platform aims to allow access to attractive, easily accessible and evidence-based prevention for youths. The system will be validated in the second step as an integrative, multi-componential and adaptive platform for the prevention of emotional disorders in youth. Based on the findings, the platform will be further refined and enriched with additional modules for specific populations and difficulties in future.

Join the REThink community and be the first to know about
opportunities to test the therapeutic tools in the platform.

Ecological mood assesment and intervention tools

Mood Wheel

Mood Wheel is a  web and mobile-based app that uses experience sampling procedures for the assessment of current/previous distress and positive emotions. The aim of the app is to inquire about the valence, control and functionality of users’ emotions.


PsyPills is a self-help psycho-educational instrument intended to build stress resilience and to target (only) mild and transient negative mood states, alone or in combination with other methods/instruments.

Psychological Pills (PsyPills) are inspired by Rational-Emotive & Cognitive-Behavioral Therapy (CBT/REBT), which has strong evidence for its efficacy/effectiveness in human development/health promotion and in the treatment of a variety of psychological conditions.

The PsyPills app was tested in a pilot study and showed positive effects on reducing distress. We will test the efficacy of the app adjunct to other therapeutic tools within the platform in our projects.


The REThinkEMOTIONS platform is fully implemented and can be accessed using the following link: and on Google Play and App Store.

The EMA (Mood Wheel) application was developed and is available on Google Play and will be integrated in the REThinkEMOTIONS Platform.

The study assessing the REThinkEMOTIONS Platform's validity for the evaluation of children and adolescents' levels of emotion regulation abilities has been implemented, and has successfully collected data from 196 parents and youths.

The following step consists in refining and personalizing the REThink online game based on emotion regulation difficulties and integrating it with the EMA tools in the REThinkEMOTIONS platform. We are also in preparation to start recruitment for the second study testing the usability of the platform and the efficacy of its main game-based emotion regulation strategies.

Update December 2022

On this phase of the project the REThink EMOTIONS platform was refined in order to be more accessible for users and researchers. Also, we implemented refinements in the REThink Game based on the feedback we collected from the participants in the studies. MoodWheel App was refined also and extended to collect data regarding physical activity and PsyPills app was re-implemented using latest technologies.

All the apps (REThink EMOTIONS, REThink Game, MoodWheel and PsyPills) are freely available on Google Play and App Store.

In the phase we implemented two research project where the REThink Game levels were tested as a standalone interventions and in combination with MoodWheel and PsyPills Apps for the stress reduction in children and adolescents.

Following steps in this project constist of a full scale trial to test the REThink Game intervention and EMA/EMI Apps for prevention of ER disorders in youths.


Update December 2023

On this phase of the project the main focus was on the implementation of the SMART trial with the aim of testing the game-based intervention combined with ecological momentary assessment and intervention apps for training the emotional abilities in children and adolescents aged 8 to 16. Also, the REThink game was upgraded with subtitles in Portuguese and Ukrainian language, enriching its accessibility. Moreover, we have calculated norms based on the scores at the assessment system of the REThink game and implemented them in the platform, so children and adolescents received automatic recommendations on each level of the game considering their scores.
