Plain English Summary
Background and study aims
People with serious mental illness have a shorter life expectancy than the general population for many reasons including the effects of antipsychotic medication and unhealthy lifestyle. Walking is a simple and gentle form of exercise which may help people with psychosis lose weight. Breaking up sessions of sedentary behaviour (i.e., sitting or lying) can help prevent heart disease. We wish to test the feasibility of a 16-week intervention to increase physical activity and break up sessions of sedentary behaviour with people using adult community mental health services in Lambeth.
Who can participate?
Adult patients with a serious mental illness who are overweight, diabetic, smoke tobacco, or have a sedentary lifestyle, and who use adult community mental health services in Lambeth.
What does the study involve?
We will recruit 40 people and randomise them to 50% intervention and 50% control. We will collect outcome data on the person's level of activity (which will involve asking participants to wear an accelerometer for four days pre and post intervention) and wear a pedomoter during the intervention. We will also collect details of sociodemographics, physical health status, and mental well-being pre and post intervention. We will also undertake a process evaluation of the intervention to understand the experience of participants by interviewing participants after the intervention has finished. We will use the information from this study to plan for a larger Randomised Controlled Trial.
What are the possible benefits and risks of participating?
We hope that participants will benefit from improved physical health in terms of increased activity, possible weight loss and increased well-being. We do not foresee any risk for the participants but there is potential for a bruise to occur following the blood test and wearing the accelerometer may be burdensome for participants.
Where is the study run from?
South London and Maudsley NHS Foundation Trust (UK).
When is the study starting and how long is it expected to run for?
September 2015 to June 2016.
Who is funding the study?
National Institute for Health Research (UK).

Walk this Way: a pilot study investigating the effect of a motivational pedometer based walking intervention to reduce sedentary behaviour and increase activity levels of people with serious mental illness
Our study questions is: can we recruit people with serious mental illness, who also have physical risk factors, to a walking intervention and retain them in the intervention for four months?

Single-centre small-scale randomised controlled trial
Primary study design
Secondary study design
Randomised controlled trial
Patient information sheet
Serious mental illness defined as schizophrenia, bipolar disorder or major depression
Our intervention is a four month intervention to support people to be more active. This will include an initial group education session regarding the benefits of physical activity lasting approximately 2.5 hours, two weekly 'coaching' sessions with a mental health worker, and the provision of a pedometer to measure the number of steps taken. Participants will also be invited to a weekly walk.
The control group will receive brief information on the benefits of being more active in one individual session.
Primary outcome measure
Amount of sedentary behaviour and physical activity measured by an accelerometer which will be worn by participants for four days before and after the intervention
Secondary outcome measures
1. BMI and waist circumference
2. Self report sedentary behaviour and physical activity measured using the International Physical Activity Questionnaire
3. Motivation to engage in physical activity measured using the Behavioural Regulation in Exercise Questionnaire 2
4. insulin resistance, long-term blood glucose control, fasting lipids and c reactive protein measured from blood samples collected from participants
5. Mental well-being measured using the Warwick Edinburgh Mental Well-being Scale
6. Functional mobility measured using the Timed Get up and Go (TUG) Test
All outcomes, primary and secondary, will be measured at baseline and follow-up, which is at the end of the 16-week intervention.
