Game based Cognitive-Behavioral Therapy: REThink therapeutic game is an online therapeutic game developed by David and collaborators (2018).

The seven levels of the game were developed based on the REBT model and each level trains an ability:

Level 1: identify the emotional reactions, and differentiating between basic emotions, complex emotions, and functional and dysfunctional emotions; Level 2: identify cognitive processes.

Level 3: identify the relation between cognitive processes, emotions, and behavioral reactions; Level 4: change irrational cognitions into rational cognitions; Level 5: build problem-solving skills; Level 6: build relaxation skills; Level 7: consolidate of the previous skills and building happiness skills. A new level will be unlocked once every three days. In order for a level to be unlocked, the previous one must have been completed.

Duration of the intervention: 21 days (a total of seven levels unlocked every three days)

In the treatment as usual group the child/adolescent benefits from a free trial version of the REThink game which means a shorter version of each level of the game.
