This study was conducted to characterize the long-term effect of mobile-based education on Chinese female freshmen and disclose the possible predictors of their willingness to get vaccinated based on the information-motivation-behavioral skills (IMB) model.
We randomly assigned 509 participants to a 7-day mobile-based educational intervention or control group and collected information about general information, health, and sexual behavior, HPV vaccination intention and action, HPV-related knowledge, cognition, and behavioral skill by an online self-administrated questionnaire at baseline, post-intervention, and at the 1-month and 3-month follow-ups.
The intervention arm showed an improvement in IMB scores after education. Despite the persistent improvement in knowledge, the improvement in their motivation and behavioral skills decreased at the 1-month and 3-month follow-ups. Participants' vaccination willingness was elevated after the baseline survey in both the intervention and control groups, while the overall appointment/vaccination rate was only 3.73% 3 months later. The intention to get vaccinated was associated with knowing HPV (adjusted OR: 2.37, 95% CI: 1.44 - 3.89), perceiving more barriers (adjusted OR: 2.16, 95% CI: 1.44 - 3.25), higher subjective norms (adjusted OR: 2.05, 95% CI: 1.26 - 3.32), and having more behavioral skills (adjusted OR: 2.95, 95% CI: 1.79 - 4.87).
Seven-day mobile-based education was effective to increase IMB model scores among female freshmen. However, the improvement in motivation and behavioral skills was not persistent. Information, perceived barriers, subjective norms, and behavioral skills were discovered to be influencing factors of vaccination intention. Future research with longer, more convenient, and more tailored education to the main influencing factors is warranted.
本研究旨在描述基于移动设备的教育对中国大一女学生的长期影响，并根据信息-动机-行为技能（IMB）模型揭示影响她们接种疫苗意愿的可能预测因素。
我们将 509 名参与者随机分配到为期 7 天的基于移动设备的教育干预组或对照组，并在基线、干预后以及 1 个月和 3 个月随访时通过在线自填问卷收集一般信息、健康和性行为、HPV 疫苗接种意愿和行为、HPV 相关知识、认知和行为技能信息。
干预组在教育后 IMB 评分有所提高。尽管知识持续提高，但动机和行为技能的提高在 1 个月和 3 个月随访时下降。在基线调查后，干预组和对照组的接种意愿均有所提高，而 3 个月后总体预约/接种率仅为 3.73%。接种意愿与了解 HPV（调整后的 OR：2.37，95%CI：1.44-3.89）、感知更多障碍（调整后的 OR：2.16，95%CI：1.44-3.25）、更高的主观规范（调整后的 OR：2.05，95%CI：1.26-3.32）和更高的行为技能（调整后的 OR：2.95，95%CI：1.79-4.87）有关。
为期 7 天的基于移动设备的教育对女大学生的 IMB 模型评分提高有效。然而，动机和行为技能的提高并不持久。信息、感知障碍、主观规范和行为技能被发现是接种意愿的影响因素。未来的研究需要针对主要影响因素进行更长、更方便和更定制化的教育。
