[目的/意义] 通过调查问卷和实验相结合的方法探究处于健康行为改变过程不同阶段的个体接收不同的框架化信息后健康风险认知及相应行为改变决策的变化情况的差异，确定何种信息能更有效提升处于不同变化阶段个体对风险的认知并促进行为改变决策形成，为下一步进行不良行为改变的纵向信息干预提供依据。[方法/过程] 基于前期研究提出的综合理论模型，选取按时吃早餐作为研究特例，利用自制问卷对被试者进行横断面考察研究。最终通过对所获得数据的统计分析，对其中具有统计学差异的结果进一步讨论，得出可行的干预意见。[结果/结论] 在健康行为改变的初期（前意向阶段、意向阶段），负性框架信息更有助于个体提升风险认知进而促进行为改变决策的形成，而在健康行为改变的中后期（准备阶段、行动转变），信息框架不再对风险认知的提升程度具有差异，但此时正性框架信息能够通过对自我效能的显著提升来促进个体产生行为改变决策，而信息框架对处于健康行为改变终末期（维持阶段）的个体未产生显著影响。
[Purpose/significance] We adopted experiment and questionnaires to investigate the difference in the change of health risk perception and health behavior change decision of individuals at different stages of the healthy behavior change process after receiving different framed information, in order to determine which information can more effectively improve their awareness of risks and promote the formation of change decisions, and to provide a basis for the longitudinal information intervention of adverse behavior change in the next step.[Method/process] Based on the theoretical model proposed in the previous study, we selected eating breakfast on time as the special case of the study, conducted cross-sectional investigation and study on the subjects by using the self-made questionnaire, and conducted statistical analysis on the data obtained, and analyzed and discussed the results with statistical differences, so as to obtain feasible intervention opinions.[Result/conclusion] In the early stages of the health behavior change (i.e. the precontemplation and the contemplation), negative frame information more helps individuals to increase risk perception and promote the formation of behavior change decision, and positive framework information more helps individuals feel tendency of decision-making of entering to the next stage in the mid-late in health behavior change while there is no difference in the impact of the frame on health risk perception (i.e. the preparation and the action).But the individual is not susceptible to the influence of the framed information at end-stage phase of health behavior change (the maintenance).
