Summary

This summary is machine-generated.

This study co-designed text messages to improve contact lens hygiene compliance. The resulting 88 optimized messages, delivered in sequences, aim to reduce infection risks for contact lens wearers.

Area Of Science

  • Ophthalmology
  • Public Health
  • Behavioral Science

Background

  • Poor hygiene compliance among contact lens wearers increases corneal infection risk.
  • Text message interventions offer a scalable approach for health behavior change.
  • This study focused on co-designing a text message intervention for contact lens hygiene.

Purpose Of The Study

  • To co-design a text message intervention to improve contact lens hygiene compliance.
  • To assess user satisfaction and discontinuation rates associated with the intervention.
  • To develop optimized, semi-personalized text message sequences for behavior change.

Main Methods

  • Messages were drafted using compliance advice and behavior change theory.
  • Expert (eyecare practitioners, health psychologists) and patient (patient advocates, lay users) feedback was gathered iteratively.
  • Readability was assessed and refined using the Flesh-Kincaid scale; message sequences were pilot tested.

Main Results

  • An initial 95 messages were refined, with 62% modified and 5% deleted based on expert and lay feedback.
  • Focus groups emphasized engagement, education, and simplification, leading to further message revisions.
  • The final library comprises 88 optimized messages, with 17 semi-personalized sequences developed and pilot tested.

Conclusions

  • Co-designing and evaluating text messages for contact lens hygiene is feasible.
  • The developed intervention resulted in a library of 88 optimized text messages.
  • These messages are structured into semi-personalized sequences for potential use in healthcare.
