Message Frame-Tailoring in Digital Health Communication: Intervention Redesign and Usability Testing
ABSTRACT
Background:
Message frame-tailoring based on the need for autonomy is a promising strategy to improve the effectiveness of digital health communication interventions. An example of a digital health communication intervention is PAS, an online content-tailored smoking cessation program. PAS was effective in improving cessation success, but its effect sizes were small and disappeared after six months.
Objective:
We aim to improve the effectiveness of PAS further by incorporating message frame-tailoring, providing smokers with autonomy-supportive or controlling message frames – depending on their individual need for autonomy.
Methods:
Various methods were used to redesign the PAS program to include message frame-tailoring with optimal usability: usability testing, think-aloud methodology, heuristic evaluations, and an online experiment.
Results:
The most autonomy-supportive and controlling message frames were identified, the cut-off point for the need for autonomy to distinguish between people with a high and low need for autonomy was determined, and the usability was optimized.
Conclusions:
This resulted in a redesigned digital health communication intervention that included message frame-tailoring and had optimal usability. A detailed description of the redesigning process of the PAS program is provided.
