Study type
Interventional
Description of intervention(s) / exposure
Intervention group: Participants in this group will be provided access to a bespoke expert-moderated, peer-to-peer online support group (OSG), in addition to being given details of the My Joint Pain website.

The OSG will focus on providing peer-to-peer support through discussion forums. It will also provide evidence-based information posts and advice from ‘expert’ health professional(s) who have been trained, are culturally sensitive and who support a belief in the ability of people with knee OA to learn self-management skills. The ‘expert’ will also moderate posts and remove inappropriate posts (such as product advertising) or posts with offensive tone or language. The 'expert moderator' will be a pool of people. Anyone who carries out the 'expert moderator' tasks will have expertise in knee OA management and the written communication skills required for role. They will all be staff members of the Centre for Health Exercise and Sports Medicine. Where specific expertise from a physiotherapist is required, a moderator with a physiotherapy background will provide the response.
Participants may engage with the OSG as much or as little as they like but will be requested to log in at least once.
Quantity and quality of engagement with the OSG and website will be assessed using a combination of analytics (i.e. time spent on the forum, number of posts during first 3 months, number of posts during second 3 months), survey and qualitative interviews.

The My Joint Pain website is a freely available information website developed and maintained by Arthritis Australia: https://www.myjointpain.org.au/ . This website has been developed for Australian users and provides up to date information about OA management including general information and services available, a risk assessment tool, and a management planning tool.

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)
To conceal allocation, the randomisation schedule will be accessed via a password-protected, computer program by a researcher not involved in participant recruitment scheduling or assessment. The person who will determine if a potential participant is eligible for inclusion in the trial will be unaware, when this decision is made, to which group the participant will be allocated.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation schedule will be computer generated in advance according to a 2:1 ratio, using random permuted blocks of varying sizes (4-10) by a person not involved in recruitment of participants (JK, biostatistician).
Masking / blinding

Quantitative analysis plan

Outcome measures:
Psychological determinants and health outcomes will be reported descriptively by treatment group assignment.

Sample size estimation for full RCT:
For this question we look at the upper bound of the 95% confidence interval for the SD for our chosen main trial primary outcome measures.

Budget estimation for full RCT:
Here we look at the hours of work required by the moderator for moderating the OSG once it has momentum, and the costs of recruitment for the 60 pilot study participants.

Feasibility:
Here will consider the following:
- Quantity and quality of engagement from analytics and qualitative study
- Satisfaction with OSG from survey question and qualitative study
- Recruitment and retention feasibility
- Fidelity to study protocol – missing data

Data pertaining to these feasibility questions will be obtained from the questionnaire responses and reported descriptively, plus supplemented by findings from the qualitative analyses.

Qualitative analysis plan

For both qualitative studies, in addition to summarising the content into broad categories e.g. type of social support, thematic analyses of the data will be conducted following procedures described by Braun & Clark [1].

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
Due to the very small number of participants and the semi-public nature of the forum posts for those allocated to the intervention group in this pilot study it will be difficult to ensure anonymity of the participants.
