myMCT OCD Manual (English)

myMCT is a self-help manual that seeks to impart knowledge and coping strategies related to the “thought traps” typical of patients with OCD. Thought traps are unhelpful ways of collecting and making sense of certain types of information, such as paying attention to potentially dangerous aspects of the environment rather than to neutral features, thinking that everything must be perfect, or feeling overly responsible for others. These thought traps can play a role in causing OCD and its progression. A recent meta-analysis by Philipp et al. (2019, link) shows that myMCT significantly reduces OCD symptoms relative to control conditions.

We provide the myMCT manual and its worksheets at no cost to people with OCD symptoms. However, developing, updating, evaluating and distributing the intervention in various languages is an enormous task, so we ask you to donate. All donations go directly to our research. You can register and download the materials via this link

A preliminary version of the concept was successfully tested in a recent research trial with 86 OCD patients: The myMCT had a positive and significant impact on obsessions and depression relative to the control condition. If you are interested in the results, you can download the corresponding scientific article below. These pilot findings were replicated in three more rigorous clinical trials (Hauschildt et al., 2016; Moritz et al., 2016; Moritz et al., 2018); myMCT led to a significant decline of obsessive symptoms and also improved knowledge on cognitive biases in the disorder. A meta-analysis by Philipp et al. (2019), which considered several studies, shows that myMCT led to a significant decline of OCD symptoms.

Doubt Therapy

We have recently adapted an intervention called "doubt therapy" by Dr. Kieron O'Connor for self-help. Our controlled study (doubt therapy versus wait-list control) showed a significant positive effect of doubt therapy on obsessions in the course of four weeks. You can download the self-help manual here.

Please help us to help others!

Recognizing the difficult financial situation of many people suffering from obsessive-compulsive disorder (OCD), we offer this manual and other treatment programs we have developed free of charge. Moreover, it is our explicit goal to evaluate and further improve myMCT by continuing scientific research. However, research is expensive. We therefore rely on federal funding and donations. If you would like to support us in providing free treatment materials to people with psychological disorders, we would be very grateful. We will of course provide these materials to you at no cost whether or not you make a donation.

No one should feel morally obligated to donate! Donations will be used to further develop myMCT. Upcoming projects include translation of our manuals into other languages, improvements of the manual, and payment of staff members who conduct research studies. If needed for tax purposes, we are happy to send you a receipt (please send an email to Steffen Moritz ( and include your postal address and full name). Donations may be made to the account below or online. Please inquire about different possibilities for sponsorship. Please donate to the following account (tax certificates will be issued on request).
