GG OCD aims to improve symptoms of OCD, specifically negative thinking, by increasing the user’s awareness of negative thoughts and training the brain to challenge them. The app guides users through 47 “levels,” 15 of which are available for free. Each level consists of short games. The first few levels aim to promote positive self talk. Later themes include: self esteem, belief in change, self criticism, negative thinking, coping, and more. There are also 3 assessments as the user progresses through the levels. Additional features such as mood tracking can be unlocked through purchase of a subscription or a one-time fee.

Research on this App

A single-case study assessed the usefulness of GGOC as a relapse prevention tool for OCD, and findings supported the efficacy of GGOC for individuals with OCD, and its contribution to maintaining gains after CBT. (Pascual-Vera, Belén, et al. 2018.

Other research has been done to apps related to GGOC:

In one study exploring the GGRO app, 50 university students aged 20-24 years old, who had subclinical levels of Relationship Obsessive Compulsive Disorder (ROCD) symptoms, were randomized into an a group that immediately used the app (n=25) or a group that delayed usage of the app (n=25). All participants completed the following questionnaires: Relationship Obsessive Compulsive Inventory (ROCI), Partner-Related Obsessive-Compulsive Symptoms Inventory
(PROCSI), Obsessive Beliefs Questionnaire-46 (OBQ-46), Obsessive Compulsive Inventory-Revised (OCI-R), Not Just Right Experiences Questionnaire Revised (NJRE-Q-R), Rosenberg Self-Esteem Scale (RSES), Intolerance of Uncertainty Scale-Revised (IUS-R), Social Interaction Anxiety Scale (SIAS), and Depression Anxiety Stress Scale-21 (DASS-21). Based on repeatedly using MANOVAS, participants from both groups indicated greater decreases in ROCD symptoms, OCD beliefs, and social anxiety symptoms. This study showed support that this intervention might be useful in decreasing subclinical ROCD symptoms.

In one study exploring the GGRO app, 97 students were randomized to either immediate use of the app (i.e. they started using the app at baseline and continued for 15 days) or delayed use of the app (i.e. they started using the app 15 days after baselines and continued for 15 days). All participants completed a web-based assessment, with questionnaires relating to maladaptive beliefs, mood and OCD symptoms at baseline, 15 days following baseline and 30 days following baseline. All participants showed a reduction in OCD-related beliefs and OCD symptoms. In the immediate use group, all effects remained significant at follow-up. (Roncero, M., Belloch, A., & Doron, G. 2019.

In an exploratory study, 36 students started the trial and 20 students completed. Participants used a treatment delivered via mobile app for 15 days and completed pre- and post- measures of OCD-beliefs, mood and OCD symptoms. Results showed a significant reduction in OCD symptoms and OCD-beliefs. (Roncero, M., Belloch, A., & Doron, G. 2018.
