简要总结
Obsessive Compulsive Disorder (OCD) is a significant mental health problem worldwide. OCD typically begins in young adulthood, and without adequate intervention, often takes a chronic course. Individuals with OCD may suffer impaired relationships, and ability to engage in leisure activities, study or work. Thus, prevention efforts are crucial to target OCD symptoms before they worsen.
The goal of this randomized-controlled trial (RCT) is to evaluate the effectiveness of a self-guided OCD program on a mobile phone application in young adults with subclinical OCD symptoms.
Hypothesis 1a: The intervention group will report significantly lower OCD symptoms (primary measure) at post-intervention and 1-month follow-up compared to the control group.
Hypothesis 1b. The intervention group will report significantly lower depression, anxiety and stress symptoms (secondary measure) at post-intervention and 1-month follow-up compared to the control group.
Hypothesis 2. Perfectionism will moderate the expected relationship between the OCD intervention and the reduction of scores on both primary and secondary measures, i.e. individuals with lower levels of perfectionism will benefit more from the OCD intervention than those with higher levels of perfectionism.
详细描述
Procedure:
Interested individuals will sign up for the study via an online survey link on the university's recruitment sites. They will first complete a pre-screening questionnaire on Qualtrics and be assessed on their eligibility based on the inclusion criteria (able to read and understand English, being a student from the National University of Singapore aged 18 to 30, and presenting with moderate subclinical OCD). Eligible participants read the Participation Information Sheet, and after providing informed consent, complete measures on depression, stress, anxiety, and perfectionism. They will also provide their demographic information (age, gender).
Next, participants are randomized to either the intervention or active control condition using simple randomization procedures and guided to download the mobile application on their mobile phone. Participants in the intervention group will undergo 8 days of the OCD learning program, while participants in the active waitlist control group will undergo 8 days of the cooperation learning program. Participation in each program is estimated to be about five minutes per day.
Upon completion of the 8-day program, participants will receive a survey link to complete measures on OCD, depression, anxiety, stress, and the App Engagement Scale. One month upon completion of the 8-day program, participants will be sent a survey link to the same survey, without the App Engagement Scale. They will also be briefed with an information sheet explaining the main purposes of the study. All participants will be given access to all well-being programs available on the app at the end of the study for their personal use. They will be reimbursed with either course credits or a small monetary fee for their participation in the study. Participants who chose to volunteer their participation will not be reimbursed.

主要结局
Change of obsessive compulsive disorder symptoms
时间窗: Baseline, 8 days (completion of intervention), 4 weeks (follow-up)
The Obsessive Compulsive Inventory - Revised (OCI-R; Foa et al., 2002) is used. The OCI-R is an 18-item self-report questionnaire which assesses OCD symptoms across 6 subscales: washing, checking, neutralising, obsessing, ordering, and hoarding. Each item is rated on a 5-point Likert scale with scores ranging from Not at all (0) to Extremely (4). The total score (ranging from 0-72) is the sum of all the items.
次要结局
- Change of depression, anxiety and stress symptoms(Baseline, 8 days (completion of intervention), 4 weeks (follow-up))
