Brief summary
By conducting a double-blind randomised, controlled trial with 150 participants, we will evaluate the effect of behaviour change text messages over 6 months. The intervention involves sending contact lens (CL) wearers a sequence of text messages, similar to the ones that have been proven to be successful in other public health areas such as cardiovascular disease, breast cancer and obesity. The text messages have been carefully co-designed and constructed to be educational and persuasive with the aim to change the behaviour of participants. Participants will be recruited from online advertisements, including social media, and also from optometry clinics. A pre-determined sequence of up to four text messages per week will be sent to the test group by using an online platform. The control group will get a minimal sequence of administrative messages. Data collection will be through a series of self-report questionnaires which will occur at baseline, 3-months, and 6-months.
Interventions
The TXTCLEAN trial is designed as a randomised, controlled, double-blinded trial with two parallel groups and endpoints of 3 and 6 months.
The intervention messages have been created using peer-reviewed guidelines from global Optometric associations which have been modified using evidence-based behaviour-change techniques and refined by an expert review panel and contact lens lay-user focus groups.

The TXTCLEAN trial is designed as a randomised, controlled, double-blinded trial with two parallel groups and endpoints of 3 and 6 months. The intervention messages have been created using peer-reviewed guidelines from global Optometric associations which have been modified using evidence-based behaviour-change techniques and refined by an expert review panel and contact lens lay-user focus groups. Data collection using online self-report questionnaires (Qualtrics XM data capture platform) will be used for all participants. These procedures will occur at baseline, 3 months and at 6 months. The intervention will be sequenced and sent using BURST SMS automated online messaging platform. Examples of text messages include the following: 'Did you know that your fingers contain bacteria that can be transferred to your eyes when you put on contacts? One of the best ways to keep your vision clear and eyes healthy is handwashing with soap and water followed by proper drying.' 'Contacts can be so comfy that you may want to keep them in all night. Don’t be tempted! Key research shows that removing lenses before sleeping is important to keep your eyes healthy for life.' The dose schedule for the test group is 4 text messages per week for the first 3 months followed by 2 messages per week for the final 3 months. The sequence of messages will be semi-personalised (using the participants first name and a reference to their chosen activity or sport where appropriate) and group-relevant (ensuring new wearers, existing wearers, daily disposable and reusable wearers receive appropriate messages). Personalisation will occur once baseline data is collected and extracted to ensure the correct personalised sequence is sent. Evaluation using self-report questionnaires will include measures of fidelity (participant adherence to the intervention), complete delivery of the intervention, receipt of the text messages and the enactment (habit change applied to everyday life) of participants. A log of intervention delivery detailing the times the text messages were sent, what proportion were delivered successfully, and the click rate of links positioned within the text message.
