Brief summary
This project aims to test the appeal, feasibility and effects on eating behaviours of a scalable, evidence-based, web- and phone-delivered healthy eating program for socioeconomically disadvantaged adults with Type 2 diabetes. The project also aims to test the effects of the program on food-related skills and attitudes, including self-efficacy and perceived barriers to selecting and preparing a balanced healthy diet. Sixty adults with Type 2 diabetes, and who hold a health care card or pension (indicators of socioeconomic disadvantage), will be recruited, with 40 expected to complete the program and evaluations (conservatively assuming up to 33% drop-out). Participants will receive a 12-week, skills-based behaviour change program, aimed at increasing healthy eating skills, attitudes and behaviours. It is based on an evidence-based behaviour change program developed by the investigators, and delivered using 6 website modules and 36 SMS text messages. Effects on eating behaviours and attitudes will be assessed at baseline, immediately after the intervention (week 12), and six months (26 weeks) later (ie, at 12 and 38 weeks post-baseline). We will also assess participants' perceptions of the program (process evaluation) at weeks 12 and 38.
Interventions
The intervention is a 12-week web- and text-based program providing theory- and evidence-based behaviour change support for heathy eating. The approach is informed by Social Cognitive Theory (Bandura, 2004) and builds on previous work by the investigators (e.g. Ball et al., AJCN 2016). It was designed by the investigatory team, who have research expertise in behaviour change, dietetics, diabetes care, and technology-delivered interventions, and utilised input from clinicians (Endocrinologists, D
The intervention is a 12-week web- and text-based program providing theory- and evidence-based behaviour change support for heathy eating. The approach is informed by Social Cognitive Theory (Bandura, 2004) and builds on previous work by the investigators (e.g. Ball et al., AJCN 2016). It was designed by the investigatory team, who have research expertise in behaviour change, dietetics, diabetes care, and technology-delivered interventions, and utilised input from clinicians (Endocrinologists, Diabetes Nurse Educators) and from people living with Type 2 diabetes. The program is designed to provide participants with skills and knowledge related to healthy food purchasing and preparation, including budgeting, menu/meal-planning, food shopping tips, and cooking/meal preparation skills. It targets the following determinants of diet: knowledge and skills; self-efficacy/confidence; and perceived barriers (budget/affordability, family preferences, time, taste, skills). It engages participants in effective behaviour change techniques, including setting goals for purchasing and consuming key food groups; self-monitoring consumption; engaging social support from family and friends; and problem-solving key barriers to healthy eating. Participants will have access to the trial website, which includes six skill-based modules (covering areas including how to make a healthy eating plan; smart food shopping; time saving meal strategies; food storage, cooking, reducing waste; and modifying recipes). Access to the modules will be provided sequentially, on a two-weekly basis. Over the three month intervention, participants will also receive three text messages/week (36 in total) which provide support, feedback and encouragement to review goals, continue to engage with different components of the website and eat healthily. There may be interaction between participants or between participants and clinicians, only as part of usual care during the intervention period (ie not an intervention component). Engagement with the program will be assessed as a marker of fidelity via both self-report survey items and through website analytics (logins, duration of use).

Inclusion criteria
Adults aged 18 to 75 years with Type 2 diabetes. Participants will need to have, and use a mobile phone, be familiar with receiving and reading text messages, and have either mobile data allowance to access the Internet, or a mobile device (phone, tablet) or computer with internet access, or be willing to use a computer with internet access at a public or hospital library. Participants will be socioeconomically disadvantaged, as determined by being in receipt of either a health-care card or a pension as the main source of income
Exclusion criteria
Participants will be excluded if they cannot speak or read English, cannot use mobile text messaging or access the internet, are pregnant, breastfeeding, or if they have an eating disorder or clinical depression (because diabetes management is typically more complex in these cases).
