Brief summary

The overall project aim is to investigate the effectiveness of adding an expert-moderated, peer-to-peer online support group (OSG) to an information website for people with clinically diagnosed knee osteoarthritis (OA). This study will investigate the feasibility of conducting the RCT by exploring fidelity (to trial and intervention protocols), satisfaction and engagement with the planned interventions, outcomes and costs. The primary objective will be to determine the feasibility of delivering the intervention in a trial setting and of recruiting and retaining participants. In terms of outcome measures, we will explore the impact of the intervention on psychological determinants that can explain self-management and lifestyle behaviour change. We will also measure behaviour and health outcomes as part of the feasibility assessment. The study will include two nested qualitative studies that will explore the type and content of posts, and the perceptions and experiences of participants in the OSG. We will conduct a two-arm, pragmatic parallel-design randomised controlled pilot trial (RCT) in 60 volunteers (20 in control group, 40 in intervention group) from around Australia who have clinical knee OA. The study will be run from the Centre for Health, Exercise and Sports Medicine at the University of Melbourne.

Interventions

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

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.
