BACKGROUND Computerized mental health interventions have shown evidence of their potential benefit for mental health outcomes in young users. All of the studied interventions available in the review and scientific literature can be classified as "serious games". Serious games are computerized interventions designed from the start with the objective of improving specific desired health outcomes. Moreover, there are reports of users experiencing subjective benefits in mental health after playing specific commercial games. These were games not intentionally made with a therapeutic objective in the design process. An example is the videogame "Journey", first released for the Playstation 3 console in 2012 which won "Game of the Year" in the 2013 D.I.C.E awards. The creator of the game describes the game as a short, 2-3-hour narrative experience in which the player goes through the "Hero's Journey" following a classic 3-part structure. There were more than 100 testimonials from players describing how the game helped them cope with psychological or personal issues. Some of them explicitly described recovering from depressive episodes through playing the game. OBJECTIVE To conduct a pilot test of the efficacy of the videogame Journey in reducing depressive symptoms in an acute impatient setting METHODS Depressive symptomatology was measured before and after the intervention using the Hamilton Rating Scale for Depression (HRSD) The intervention was conducted in an isolated room using a Playstation 3 console with the videogame "Journey" developed by Thatgamecompany. No internet access was allowed. The game was played over the course of 4 30-45 min sessions in a two week period. RESULTS The initial score in the Hamilton Rating Scale for Depression (HRSD) was 30, indicating a very severe depression. After the intervention the HRSD score was 10, showing a mild depression. CONCLUSIONS The Videogame Journey, a commercial game first available for the Playstation 3 console in 2012, was not created as a serious game with potential health benefits. Our pilot test is the first case report of a commercial game showing a potential effect in reducing depressive symptoms, which is consistent with the previous informal reports of users online.
