Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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).

Efficacy
Statistical methods / analysis
This is a feasibility (pre-post-follow-up) study. Intervention effects will be assessed by comparison of pre-(baseline), post-(12 weeks) and follow-up (38 weeks) intervention measures (repeated measures t-tests and Analyses of Variance) of dietary intake, dietary self-efficacy and barriers. Measures of program appeal and usability will be analysed using descriptive statistics (frequencies, ranges) for quantitative indicators, and thematic analysis for open-ended questions.

Our experience suggests that a sample of n=60 (conservatively assuming up to 33% drop-out) is sufficient for generating rich qualitative and contextual data on intervention engagement, feasibility and appeal, and estimates of effect that will help inform future larger studies. Our clinical co-investigators have confirmed that this number is feasible, with around 80 patients/week - mostly with Type 2 diabetes - attending clinics.
