Interventional
Description of intervention(s) / exposure
A two-group randomised, controlled, repeated measure study design will compare the generic Arthritis Self-Management Program (ASMP) delivered by lay leaders with the disease specific knee osteoarthritis self-management program (OAK) delivered by health professionals. Both the OAK program and the ASMP are self-management programs and are conducted over 8 weeks in a group setting. The first week and the last week include assessment sessions, and the interim 6 weeks (one 2.5hour session per week) consists of the delivery of the two different self-management programs (OAK and ASMP). All participants in both groups will continue to receive standard medical management as required. The duration of both interventions is 6 weeks. The ASMP will be the "control" group against which the OAK group is compared.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Pre-made cards (an equal number of OAK and ASMP cards) will be placed each in a sealed, opaque envelope. These will then be placed in an enclosed box. After a subject has signed informed consent, the box will be opened and an envelope containing a randomisation card will be chosen by a third party.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be allocated to study groups using simple randomisation.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Study participants will be unaware to which group they have been allocated. Assessor measuring outcome will also be blinded to group allocation. Program facilitators will be aware of group allocation. Data analyst will be unaware of group allocation.
