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 Personal Advice in Stopping smoking (PAS), a web-based content-tailored smoking cessation program. PAS was effective in improving cessation success rates, but its effect sizes were small and disappeared after 6 months. Therefore, investigating whether message frame-tailoring based on the individual's need for autonomy might improve effect rates is worthwhile. However, to our knowledge, this has not been studied previously.
OBJECTIVE
To investigate whether adding message frame-tailoring based on the need for autonomy increases the effectiveness of content-tailored interventions, the PAS program was redesigned to incorporate message frame-tailoring also. This paper described the process of redesigning the PAS program to include message frame-tailoring, providing smokers with autonomy-supportive or controlling message frames-depending on their individual need for autonomy. Therefore, we aimed to extend framing theory, tailoring theory, and self-determination theory.
METHODS
Extension of the framing theory, tailoring theory, and self-determination theory by redesigning the PAS program to include message frame-tailoring was conducted in close collaboration with scientific and nonscientific smoking cessation experts (n=10), smokers (n=816), and communication science students (n=19). 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 a web-based experiment.
RESULTS
The most autonomy-supportive and controlling message frames were identified, the cutoff point for the need for autonomy to distinguish between people with high and those with 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.

背景
基于自主需求进行信息框架定制是提高数字健康传播干预效果的一种有前景的策略。数字健康传播干预的一个例子是戒烟个人建议（PAS），这是一个基于网络的内容定制戒烟项目。PAS在提高戒烟成功率方面是有效的，但其效应量较小且在6个月后消失。因此，研究基于个体自主需求的信息框架定制是否能提高戒烟成功率是值得的。然而，据我们所知，此前尚未有相关研究。
目的
为了研究基于自主需求增加信息框架定制是否能提高内容定制干预的效果，对PAS项目进行了重新设计，使其也纳入信息框架定制。本文描述了重新设计PAS项目以纳入信息框架定制的过程，根据吸烟者的个体自主需求为其提供支持自主或控制型的信息框架。因此，我们旨在扩展框架理论、定制理论和自我决定理论。
方法
与科学和非科学领域的戒烟专家（n = 10）、吸烟者（n = 816）和传播科学专业学生（n = 19）密切合作，通过重新设计PAS项目以纳入信息框架定制来扩展框架理论、定制理论和自我决定理论。采用了多种方法重新设计PAS项目，以使其具有最佳可用性地纳入信息框架定制：可用性测试、出声思考法、启发式评估和一项基于网络的实验。
结果
确定了最具支持自主性和控制性的信息框架，确定了区分高自主需求者和低自主需求者的自主需求临界点，并优化了可用性。
结论
这导致了一种重新设计的数字健康传播干预措施，该措施纳入了信息框架定制且具有最佳可用性。提供了PAS项目重新设计过程的详细描述。
