Study summary

The aim of the present study was to evaluate the efficacy of GGRO reducing OCD related maladaptive beliefs and OCD symptoms. Specifically, a randomized controlled trial with crossover design was carried out in non-clinical population to assess pre-post changes in levels of OCD-related maladaptive beliefs and OCD symptoms, including relationship OCD (ROCD) symptoms, self-esteem, and depressive symptoms following 15 days of using GGRO.

Read the detailed description

The implementation of Information and Communication Technologies in the treatment or prevention of OCD symptoms has been significantly lower compared to with its application in other anxiety disorders.

Recently, an exploratory study evaluated a brief, game-like, training exercise for challenging OCD-beliefs delivered via a mobile application platform named GGRO. However, more studies are needed to test the efficacy.

Study arms

  • Experimental
    Immediate use GGRO Mobile App

    The group starts using the GGRO Mobile App immediately after the first assessment (T1) for 15 days.

    Device: GGRO Mobile App

  • Active comparator
    Delayed use GGRO Mobile App

    Delayed use GGRO Mobile App group started using the App 15 days after the first assessment (T2).

    Device: GGRO Mobile App

Interventions

  • DeviceGGRO Mobile App

    GGRO was designed to challenge maladaptive beliefs that underlie common OCD symptoms (e.g., contamination, repugnant thoughts) as well as relationships obsessions. Users are presented with 'blocks' featuring statements such as "I take things as they come" or "Everything can end in a catastrophe". Users then have to respond to these statements by either pulling 'blocks' towards themselves (i.e., downwards) or throwing the blocks away from themselves (i.e., rejecting them upwards).

What researchers measure

Primary outcomes

  1. Change in obsessive beliefs

    Score change in obsessive compulsive maladaptive beliefs measured by the short form of the Obsessive Beliefs Questionnaire (OBQ-20). Total score is computed as a mean of the 20 items, ranging from 1 "disagree very much" to 7 "agree very much". Higher scores indicate the person has more obsessive beliefs.

    Time frame: 15 days

Secondary outcomes

  1. Change in obsessive compulsive symptoms

    Score change in obsessive-compulsive symptoms measured by the Obsessive Compulsive Inventory- Revised version (OCI-R). Total score is computed as a mean of the 18 items, ranging from 0 "not at all" to 4 "Extremely". Higher scores indicate a greater presence of obsessive-compulsive symptoms.

    Time frame: 15 days

  2. Change in depression symptoms

    Score change in depression symptoms measured by Depression, Anxiety and Stres Scale (DASS). The depression scale is composed by the mean of 7 items, ranging from 0 "did not apply to me at all" to 3 "applied to me very much, or most of the time". Higher scores indicate a greater presence of obsessive -compulsive symptoms.

    Time frame: 15 days

  3. Change in Self-Esteem

    Change in score of Single Ítem Self Esteem Scale (SISE). Self-Esteem is measured with this single item ranging from 1 "not very true for me" to 9 "very true for me". Higher scores indicates a higher Self-Esteem.

    Time frame: 15 days
