Building upon extant research on the reasoned action approach and message sidedness, this study investigates the persuasive effects of one-sided and two-sided social media messages on the attitude about human papillomavirus (HPV) vaccination in the context of misinformation. Results of a controlled experiment ( = 251) indicated that compared to the control, one-sided messages addressing misinformation increased positive attitude about the vaccine as prior misperceptions increased. However, a backfire effect may be looming for individuals with lower prior misperceptions. Within the sidedness conditions, refutational two-sided messages were more effective in increasing cognitive attitude for individuals with lower misperceptions; whereas one-sided messages had a persuasive advantage for individuals with higher misperceptions. Theoretical and practical contributions are discussed.
在既有关于理性行为理论和信息片面性的研究基础上，本研究考察了在错误信息背景下，社交媒体单面信息和双面信息对人乳头瘤病毒（HPV）疫苗接种态度的说服效果。一项控制实验的结果（n=251）表明，与对照相比，当错误认知增加时，针对错误信息的单面信息会增加对疫苗的积极态度。然而，对于错误认知较低的个体，可能会出现反向效果。在信息片面性条件下，对于错误认知较低的个体，反驳式双面信息在增加认知态度方面更有效；而对于错误认知较高的个体，单面信息则具有说服力优势。本文讨论了理论和实践方面的贡献。
