Routine collection of behavioral and social drivers (BeSD) of vaccination data is essential for understanding and addressing vaccine confidence and demand to achieve high vaccination coverage. Traditional house-to-house data collection methods are resource-intensive, prompting the need for alternative, scalable approaches. This study tested the feasibility of using mobile phone surveys to collect community-level BeSD data on COVID-19 vaccination in Zambia. A cross-sectional survey of adults aged 18 and over was conducted in three districts: Lusaka, Kalomo, and Chavuma. Participants were recruited via geotargeted mobile phone messages and responded using push-button inputs. The survey adapted validated BeSD questions from the World Health Organization (WHO) framework and was administered in English and six local languages. Strategies to increase response rates were tested, including offering a small monetary incentive and conducting community outreach via radio jingles. To assess the feasibility of using mobile phone surveys to collect BeSD data, we report on response rates and the demographic distribution of respondents and describe the operational process of applying this methodology. From March to July 2024, a total of 52,983 recruitment messages were sent, yielding an overall response rate of 15.7%. Response rates varied by district, with Chavuma having the highest (68.2%) and Lusaka the lowest (4.2%). Compared to a baseline response rate of 4.7%, offering a monetary incentive increased the response rate to 31.4%, while community outreach increased it to 19.8%. Respondents skewed younger (69.5% aged 18-29 years) and male (65.9%). Mobile phone surveys present a feasible method for collecting real-time BeSD data at the community level in low-resource settings. Incentives and community outreach effectively increase participation, though results may need to be weighted to reflect population demographics.
常规收集疫苗接种行为和社会驱动因素（BeSD）数据对于理解和解决疫苗信心及需求以实现高疫苗接种覆盖率至关重要。传统的逐户数据收集方法资源消耗大，因此需要替代性的、可扩展的方法。本研究测试了使用手机调查收集赞比亚社区层面新冠疫苗接种BeSD数据的可行性。对卢萨卡、卡洛莫和查武马三个地区18岁及以上成年人进行了横断面调查。通过地理定位手机信息招募参与者，并使用按键输入进行回复。该调查采用了世界卫生组织（WHO）框架中经过验证的BeSD问题，并以英语和六种当地语言进行。测试了提高回复率的策略，包括提供小额金钱激励以及通过广播广告进行社区宣传。为评估使用手机调查收集BeSD数据的可行性，我们报告了回复率和受访者的人口统计学分布，并描述了应用该方法的操作过程。2024年3月至7月，共发送了52,983条招募信息，总体回复率为15.7%。回复率因地区而异，查武马最高（68.2%），卢萨卡最低（4.2%）。与4.7%的基线回复率相比，提供金钱激励使回复率提高到31.4%，而社区宣传使其提高到19.8%。受访者以年轻人（18 - 29岁占69.5%）和男性（65.9%）为主。手机调查是在资源匮乏地区社区层面收集实时BeSD数据的可行方法。激励措施和社区宣传有效提高了参与度，不过可能需要对结果进行加权以反映人口统计学特征。
