A Randomized Controlled Trial on the Effects of Mobile-Based Gamified Combined Cognitive Bias Modification on OCD Symptoms, Obsessive Beliefs, Cognitive Biases, Depressive Symptoms and Distress in Adults Diagnosed With OCD
Status: Recruiting
Location: See location...
Intervention Type: Behavioral
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
This randomized controlled trial examines the effects of a mobile-based gamified combined cognitive bias modification (CBM-C) intervention on obsessive-compulsive symptoms, obsessive beliefs, attentional and interpretation biases, depressive symptoms, and psychological distress. The gamified CBM-C condition is compared to a standard mobile-based CBM-C and a placebo control condition. All interventions are delivered via a mobile application. Assessments are conducted at baseline, post-intervention (week 4), and 3-month follow-up.
Eligibility
Participation Requirements
Sex: All
Minimum Age: 18
Healthy Volunteers: f
View:
• Age 18 years or older
• Primary diagnosis of obsessive-compulsive disorder (OCD), confirmed by a licensed clinician using the Structured Clinical Interview for DSM-5 (SCID-5)
• No current suicidal ideation or psychotic symptoms
• Access to the internet and a mobile phone
• Stable psychiatric medication use for at least one month prior to enrollment, with no changes in dosage during the 4-week intervention period
• No current neurological or medical condition that would interfere with participation
• Ability to perceive colored visual stimuli (e.g., no color blindness)
• Not currently enrolled in another intervention-based study
• Not receiving any other form of psychological treatment at the time of participation
Participants in this group will receive the gamified version of the combined cognitive bias modification (CBM-C) intervention, consisting of eight sessions over four weeks (two sessions per week), delivered via mobile phone. The intervention includes both attention and interpretation bias modification tasks enhanced with gamification elements.
Active_comparator: Standart Combined Cognitive Bias Modification
Participants in this group will receive the standard version of the combined cognitive bias modification (CBM-C) intervention, consisting of eight sessions over four weeks (two sessions per week), delivered via mobile phone. The intervention includes both attention and interpretation bias modification tasks, without any gamification features.
Placebo_comparator: Placebo Control
Participants in this group will receive a placebo version of the standard combined cognitive bias modification (CBM-C) intervention, consisting of eight sessions over four weeks (two sessions per week), delivered via mobile phone. The placebo version retains the structure of the standard intervention but does not include any active bias modification components.
