Brief summary: This research aims to develop a bank of text messages based on behaviour change techniques targeting specific diet and physical activity behaviours in people with type 2 diabetes

Detailed description: Aim: To develop text messages that help people with type 2 diabetes (T2D) improve their diet and level of physical activity

What is known:

Following diet and physical activity advice helps to reduce the risk of health problems for people with T2D

Just telling people about a healthy diet, or ideal levels of physical activity may not change what someone does day-to-day. Many people need support to change health behaviours

Techniques designed to help people change their behaviour, such as setting goals, can help people act

Text messages can be sent to large numbers of people, for a low cost

For the best chance of success, it is important that the messages are a) acceptable to the people receiving them and b) use techniques to help people to make changes

How the investigators are going to achieve their aim:

When asking someone to follow a healthy diet or do more physical activity, this could refer to changing lots of different behaviours such as eating less sugar or less fat and walking each day. The investigators invited people with type 2 diabetes, doctors, nurses, dietitians, and researchers to take part in a workshop to work out which behaviours are the most important ones for people with type 2 diabetes to do. The investigators have also looked at previous research and found techniques that have helped people with type 2 diabetes change their diet and levels of activity.

The investigators will now follow four steps to develop the messages:

1. Twelve to fifteen people with type 2 diabetes will take part in online focus groups to provide feedback about the target behaviours and guide the development of the text message system
2. Ten to twenty researchers will take part in a workshop. They will write messages using the techniques that have worked in previous research to target important behaviours for people with type 2 diabetes. They will then complete a survey to report whether the messages are good examples of the techniques.

2. Sixty people with type 2 diabetes will complete a survey to tell us whether they like and understand the messages and how useful they think they would be.

3. Forty people with type 2 diabetes will receive the messages for up to 3 months and take part in an interview over the phone to help us understand their experiences.

Patient and Public Involvement and Engagement (PPIE) This research has been developed with a PPIE group. Our PPIE co-applicant and PPIE group will be involved in key decisions and review any materials being sent to people with type 2 diabetes.

What the investigators will do with the findings

Explore how these messages can become part of routine National Health Service (NHS) care. The findings will be used together with work our team are doing looking at sending out text messages to help people with type 2 diabetes take their medication.

Findings will also be publicised through databases of people interested in research, diabetes charities, community groups, places of worship and publications.
