Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
If participants are randomly allocated to the intervention group, treatment will be based on the manual Individual and Group Metacognitive Therapy for Obsessive Compulsive Disorder (Rees & van Koesveld, 2009). This manual will be reviewed and modified in study 1 (development of the programme and website) in order to be used as an online self-help programme. The programme will be provided through the website 'the OCD-Doctor-Online'. A time period of six weeks will be allocated to all participants to complete the program (a total of 10 modules). At the end of each module, a number of questions will be asked to ensure that participants completely understand the content of that module. It is anticipated that each module will take approximately 1 hour to complete. In order to ensure that participants complete modules in the correct order, modules will not be available until questions from the previous modules have been completed.

Comparator / control treatment
If participants are randomly allocated to the control group, progressive muscle relaxation training will be administered online. Progressive muscle relaxation training has been successfully used in controlled trials as a credible comparison condition (e.g. Fals-Stewart, Marks, & Schafer, 1993; Twohig et al., 2010).
Participants will be provided with audio exercises weekly (15-30 minutes) for 6 weeks to teach them specific progressive muscle relaxation techniques. They will also be allocated homework to practice these exercises a minimum of once a day (15 minutes - 30 minutes).

After study 2 (implementation and evaluation of the program) is complete, participants in the control group will be provided with access to the online MCT programme if they wish.

Outcomes
Primary outcome [1] 279728 0
Obsessive-compulsive Inventory - Revised (OCI-R). The 18-item self-report questionnaire assesses several symptoms of OCD. Items on the self-report questionnaire refer to experiences that many people may have in their everyday lives. The scales assesses how much each of these items have distressed or bothered the participant in the past month.

Eligibility
Key inclusion criteria
- Have a total score on the OCI-R of 21 or greater, as defined by Foa and colleagues (2002) as the optimal cut-off to distinguish OCD clients from non-anxious clients.
- Be aged 18 years or over.
- If participants are taking medication such as antidepressants or other mood stabilisers, they must be stable on this medication one month prior to their baseline assessment.
- Participants must be willing to remain on the same dosage of the same medication throughout the entire treatment period including follow-up.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A number of inclusion and exclusion criteria apply. Once participants have gone through the screening process and are found to be eligible to participate in the research study, they will be randomly allocated to either intervention or control group. Random allocation will be conducted by computer generated software (Saghaei’s [2004] Random Allocation computer software version 1.0). All measures are self-administered online. The researchers will therefore have no knowledge of the condition to which the participant will be allocated.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The method used to generate the sequence in which subjects will be randomised will be a simple random allocation procedure. The researcher will use Saghaei’s (2004) Random Allocation computer software version 1.0 to generate randomised number lists. The researcher will correspond with a statistician from Curtin University of Technology to ensure equal group sizes. Correspondence with a professional programmer will help to incorporate the randomisation software into the website to randomly allocate participants to groups.
