Context is a prerequisite for persuasion research.Existing studies have focused on exploring the diversity of information strategies but lack comparative research on the same strategy in different contexts.This study examines cancer patients to explore the differences in perceived credibility and persuasive effectiveness of the same persuasive strategy in high-risk context.Using a between-subject experimental design that includes information orientation,information appeals,and source cues,a total of 343 valid participants were recruited.The results demonstrate the consistency of perceived credibility and the inconsistency of persuasive effectiveness of information strategies in high-risk contexts,highlighting the persuasive advantages of"emotional information"and"one-sided information",and revealing the phenomenon of"limited utility of credibility"in high-risk context.Furthermore,peripheral source cues play a moderating role in the perceived credibility and persuasive effectiveness of information.This research contributes to the development of cross-context health persuasion communication theory and provides a reference for the design of persuasive information in clinical cancer settings.
