Improving LDL-C Levels Through Temporal Self-regulation Theory-based, Personality-tailored Health Messages

Condition(s) studied

Investigational drug(s) / intervention(s)

General Message: The intervention will consist of messages and infographics embedded in participants' return of results (ROR) emails within the RESET study. Each participant will receive the ROR alongside the intervention once, at the time their results are sent. No repeat messages will be delivered. The general health message will include indications for lipid therapy, benefits of lipid-lowering medications, common side effects, risks of non-adherence, and an infographic on diet and lifestyle modification based on ACE lipid management guidance. The infographic will be included in the same ROR email.

Personalized Message: The intervention will consist of messages and infographics embedded in participants' return of results (ROR) emails within the RESET study. Each participant will receive the ROR alongside the intervention once, at the time their results are sent. No repeat messages will be delivered. The message will include the personality-tailored message with the same core content as the general message, including indications for lipid therapy, benefits of lipid-lowering medications, common side effects, risks of non-adherence, and an infographic on diet and lifestyle modification based on ACE lipid management guidance. An infographic will be included in the same ROR email. This message will contain an added component framed according to conscientiousness and neuroticism scores, as these traits are strong predictors of health behaviours. Scores will be derived from baseline BFI-44 results.

Study summary

The study is meant to run parallel to the larger study, RESET. The goal of this study is to to evaluate the effectiveness of a once-off general and personality-tailored text message on GP consultation among RESET participants identified to have high LDL-C. The main question it aims to answer is:

Will participants exposed to personality tailored advice have a higher adherence to GP consultation compared to the participants in the control group?

Researchers will compare a personalized message to a general message (with no personalization according to patients personality type) and control group to see if the messages increase adherence.

Participants are required to complete two questionnaires: one before and one after they receive their RESET results.

Eligibility

Primary outcome measure(s)

• Intention to adopt a healthier diet — From enrollment to 3 months after results have been returned.
  A 3-item, 7-point Likert scale assessing participants' intention to adopt a healthier diet. The minimum and maximum score one can attain on this measure is 3 and 21 respectively, with a higher score indicating higher intention to adopt a healthier diet.
• Intention to engage in Physical Activity — From enrollment to 3 months after results have been returned.
  A 3-item, 7-point Likert scale assessing participants' intention to engage in physical activity. The minimum and maximum score one can attain on this measure is 3 and 21 respectively, with a higher score indicating higher intention to engage in physical activity.
• Intention to visit a General Practitioner — 3 months after results have been returned.
  A 3-item, 7-point Likert scale assessing participants' intention to visit a general practitioner. The minimum and maximum score one can attain on this measure is 3 and 21 respectively, with a higher score indicating higher intention to visit a general practitioner.
