Description of intervention(s) / exposure
Participants will be randomly assigned to one of two groups: 1) Treatment with clinician-assisted Internet based Cognitive Behavioural Therapy for Obsessive Compulsive Disorder (OCD), or 2) Waitlist control. All participants will meet Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DSM-IV) criteria for OCD. All group 1 participants will separately complete 6 lessons of Internet based treatment about the management of symptoms of OCD. One lesson will be completed every 7 to 14 days (it will become available after the preceding lesson has been completed, with a minimum of 7 days between lessons and a maximum of 14 days). Each lesson will take about 15 minutes to complete. Group 1 participants will have access to summaries of each lesson, homework exercises, extra resources, weekly reminder emails, and one-on-one contact with the Clinician (Clinical Psychologist) by telephone or email in the first 2 weeks, then as required. The duration of the program is 8-10 weeks, but participants will be contacted 3 months post program and asked to complete follow-up questionnaires. Study questionnaires will be administered at application, pre-treatment, mid-treatment, post-treatment, at 3 months post-treatment, and the K10 pre-each lesson. These will take about 20 minutes to complete. The treatment materials are based on cognitive behavioural techniques.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants apply on line, followed by a telephone interview to confirm diagnosis via the Mini-International Neuropsychiatric Interview (MINI 5.0.0), a structured diagnostic interview. Participants will be randomized using a list generated prior to the study. Allocation concealment will occur in the following way: A staff member not involved in the clinical trial will generate the sequence using computer software, and place each choice in a sequentially numbered, opaque, sealed and stapled envelope.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomisation list will be generated prior to the study using computer software.

Summary
Brief summary
We have recently developed an online cognitive behavior therapy program involving exposure and response prevention for people with OCD. This study will examine the program’s effectiveness in reducing symptoms of OCD and related symptoms of anxiety, depression, distress, and disability. We will also assess how acceptable the program is to participants.
