Mobile App for Obsessive-compulsive Disorder in Adolescents

The aim of the present study is to assess the efficacy of the module GGOC-AD (GG Obsessive-Compulsive Disorder - Adolescents) in reducing obsessive-compulsive disorder (OCD) related maladaptive beliefs and OCD symptoms in adolescents from 15 to 18 years old. Specifically, a randomized controlled trial with two conditions (experimental and control) will be carried out in a non-clinical adolescent population to assess pre-post-intervention changes. After 14 days of using GGOC-AD, it is expected, primarily, to find a decrease in OCD-related maladaptive beliefs and OCD symptoms. As secondary results, we do not expect changes in emotional symptomatology, but we do expect an increase in self-esteem. Additionally, these changes are expected to be found in a one-month follow-up.

About this study

Pediatric OCD is a serious problem and, if not treated early on, is associated with significant impairment. The app GGOC, aimed at working on OCD-related dysfunctional beliefs in adults, has proven in previous studies in adult clinical and non-clinical samples, to significantly decrease maladaptive beliefs associated with OCD and obsessive-compulsive symptomatology. Also, it can significantly increase self-esteem. Therefore, it is relevant to adapt the GGOC application to the adolescent population (GGOC-AD) and evaluate its effectiveness.

Treatment and study plan

GGOC-AD (GG Obsessive-Compulsive Disorder - Adolescents)

Device

GGOC was originally designed to challenge maladaptive beliefs that underline OCD symptoms in adult population. It was adapted to adolescent population. It consists of statements that are presented to the user, and that can portray either negative ("I can't trust myself") or positive beliefs ("I have a lot of good characteristics"). Users have to respond by either pulling these towards "Accept" or "Reject".

GGN-AD (GG Neutral - Adolescents)

Device

it was designed to have a comparison group. It consists of neutral statements such as "Madrid is a Spanish city", that ought not to produce changes in the direction of our hypothesis. These have to be "Accepted" or "Rejected" based on their veracity.

Primary outcomes

  1. Change in obsessive beliefs

    Time frame: Through app completion (14 days) and 1 month follow-up

    Score change in obsessive compulsive maladaptive beliefs measured by the Obsessive Beliefs Questionnaire-Child Version (OBQ-CV). Total score is computed as a mean of the 44 items, ranging from 0 "strongly disagree" to 4 "strongly agree". Higher scores indicate the person has more obsessive beliefs.

  2. Change in obsessive-compulsive symptomatology

    Time frame: Through app completion (14 days) and 1 month follow-up

    Score change in obsessive-compulsive symptoms measured by the Obsessive Compulsive Inventory- Child Version (OCI-R-CV). Total score is computed as a mean of the 21 items, ranging from 0 "never" to 2 "always". Higher scores indicate a greater presence of obsessive-compulsive symptoms.

Secondary outcomes

  1. Change in emotional symptoms

    Time frame: Through app completion (14 days) and 1 month follow-up

    Change in depression and anxiety symptoms measured by The Patient Health Questionnaire for Depression and Anxiety (PH-4). It consists of 4 items, two for Anxiety and two for Depression, with a 4-point Likert scale (from 0 = "never" to 3 = "almost every day"). Higher scores indicate a greater presence of depression or anxiety symptoms.

  2. Change in self-esteem

    Time frame: Through app completion (14 days) and 1 month follow-up

    Change in score of Single Item Self Esteem Scale (SISE). Self-Esteem is measured with this single item ranging from 1 "It is not very true for me" to 7 "It is very true for me". Higher scores indicate a higher self-esteem.
