REThink is an online therapeutic game aimed at enhancing the emotional health of young people, grounded in Rational Emotive Behavior Therapy (REBT). The game features a character named RETMAN, who guides players through seven levels, each focused on teaching a specific emotional regulation skill. Each level has three sub-levels that progressively increase in difficulty. REThink can be used as a standalone intervention, an adjunct to self-help psychotherapeutic approaches, or for targeted skills training.

Strengths and Difficulties Questionnaire (SDQ; Goodman, 1997). The scale has 25-items within its five subscales, namely emotional symptoms (ES), conduct problems (CP), hyperactivity/inattention (HY), peer relationship (PR) problems and prosocial behavior (PS) and total mental health difficulties score (MHD). The items are rated on a 3-point Likert scale, from 0 (not true) to 2 (certainly true). The minimum score is 0 and the maximum is 40. Higher scores represent higher level of mental health difficulties.

The Child and Adolescent Scale of Irrationality (CASI, Bernard & Cronan, 1999) will be used in order to test irrational/rational beliefs as a mechanism of change. Children and adolescents were asked to express their agreement/disagreement with the 28 statements on a 5-point Likert-type scale, from 1 ("strong disagreement") to 5 ("strong agreement"). The minimum score is 28 and the maximum score is 140. Higher scores represent higher levels of irrationality.
