Family Involvement in CBGT of OCD: a Randomized Controlled Trial

Belgium80 participantsStarted 2019-09-03

Plain-language summary

With a lifetime prevalence of 1-3% Obsessive-Compulsive Disorder (OCD) is a chronic and disabling psychiatric disorder with considerable burden for the individual and society. Cognitive-behavioural group therapy (CBGT) is effective in reducing the intensity of OCD symptoms and it improves the OCD patient's quality of life. There is also growing evidence that family accommodation (FA) maintains and/or facilitates OCD symptoms, reinforces fear and avoidance behaviours in patients with OCD and is associated with family burden. Considering the promising results of involvement of family in CBGT on OCD symptoms and FA, the current study aims at investigating the effects of the involvement of the family in a 12-week CBGT protocol on the OCD symptoms, FA, burden, QOL, anxiety and depressive symptoms in OCD patients and their live-in relatives. Eighty patients with OCD and their live-in family members (partner, parent, sibling, …) between 18-65 years old will be included in this randomized controlled trial. Patients and family members will be randomly assigned to CBGT with the involvement of family or to CBGT without involvement of family. The primary goal of this study is to evaluate the effects of the involvement of live-in family members during a 12-week CBGT on OCD symptomatology and family accommodation during a 12-month follow-up period. In a secondary stage, we will explore whether the involvement of live-in family members during a 12-week CBGT will ameliorate anxiety and depressive symptoms, QOL, family functioning and burden in the patients and their live-in family.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Faster decrease and longer lasting improvement (less relapse) of OCD symptoms in patients

Timeframe: Y-BOCS will be completed at four time-points: at inclusion, after completion of the CBGT (an average of 3 months post baseline) and at 6 and 12 months post CBGT

Faster decrease and longer lasting improvement of family accommodation in family members

Timeframe: The Family Accommodation Scale (FAS) will be completed at four time-points: at inclusion, after completion of the CBGT (an average of 3 months post baseline) and at 6 and 12 months post CBGT
