Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
People with mild hip or knee osteoarthritis will take part in a behaviour change intervention which will take place over an 8-week period. During this time, participants will complete 3 motivational interviewing (MI) sessions (weeks 1-4) and 2 integrated MI-cognitive behaviour theory (CBT) sessions (weeks 5-8). Each session will last approximately 30 minutes and will be delivered in a one-to-one format. At least 1 of each session may take place in person. The remaining sessions will be delivered through an online video conferencing platform. A researcher who is trained in the MI-CBT techniques will deliver the intervention. As MI is effective for initiating behaviour change, information will be used to identify possible target areas for change where sedentary behaviour can be swapped for some form of light physical activity. Cognitive behaviour theory will be used to set those goals using self-generated options on methods to allow participants to reduce their time spent sitting by engaging in activities such as light walking, gardening or light household activities regularly into their day. A session diary will be kept by the researcher containing examples of open-ended questions and MI techniques for the researcher. The diary will also be used to record notes on participant responses in the session and during the CBT sessions will record targets for behaviour change. Attendance and completion of the number of sessions will be recorded to monitor adherence to the MI-CBT intervention.

Comparator / control treatment
Usual care.
Usual care is the routine care offered by participants' own general practitioner and other healthcare providers. No MI-CBT intervention will be received by participants in the usual care group. The researchers will neither influence nor restrict GPs', surgeons’, other practitioners’ or participants’ use of other interventions, however it will be monitored and recorded.

Summary
Brief summary
The objectives of this study will be to deliver a behavioural intervention through several sessions of integrated motivational interviewing (MI) and cognitive behaviour therapy (CBT) over an 8-week period in people with mild hip or knee osteoarthritis. All participants will be invited to take part in an education session after which participants will be randomised into a behavioural intervention group or a usual care group. Participants in the intervention group will continue to engage in an integrated motivational interviewing and cognitive behaviour change theory intervention for 8 weeks. Participants in the control group will receive the usual care from their primary healthcare provider for the same 8 weeks. Patient reported outcomes measures of joint pain, overall OA-related physical function, health-related quality of life and self-efficacy for exercise will also be collected by clinical assessment and questionnaires before and after the behaviour change intervention.
Free-living activity behaviour data will be collected using an accelerometer at various time-points during the intervention and these data will be used to estimate energy expenditure and daily and weekly activity patterns.
