With the unprecedented penetration of mobile devices in the developing world, mHealth applications are being leveraged for different health domains. Among the different factors that affect the use of mHealth interventions is the intention and preference of end-users to use the system. This study aimed to assess mother's intention and preference to use text message reminders for vaccination in Ethiopia.
A cross-sectional study was conducted among 460 mothers selected through a systematic random sampling technique. Initially, descriptive statistics were computed. Binary logistic regression analysis was also used to assess factors associated with the outcome variable.
In this study, of the 456 mothers included for analysis, 360 (78.9%) of mothers have intention to use text message reminders for vaccination. Of these, 270 (75%) wanted to receive the reminders a day before the vaccination due date. Mothers aged 35 years or more (AOR=0.35; 95% CI: 0.15 to 0.83), secondary education and above (AOR=4.43; 95% CI: 2.05 to 9.58), duration of mobile phone use (AOR=3.63; 95% CI: 1.66 to 7.94), perceived usefulness (AOR=6.37; 95% CI: 3.13 to 12.98) and perceived ease of use (AOR=3.85; 95% CI: 2.06 to 7.18) were predictors of intention to use text messages for vaccination.
In conclusion, majority of mothers have the intention to use text message reminders for child vaccination. Mother's age, education, duration of mobile phone use, perceived usefulness and perceived ease of use were associated with intention of mothers to use text messages for vaccination. Considering these predictors and user's preferences before developing and testing text message reminder systems is recommended.
随着移动设备在发展中国家的空前普及，移动医疗应用正被应用于不同的健康领域。影响移动医疗干预措施使用的因素有很多，其中包括最终用户使用系统的意愿和偏好。本研究旨在评估埃塞俄比亚母亲对使用短信提醒进行疫苗接种的意愿和偏好。
采用系统随机抽样技术，对 460 名母亲进行横断面研究。首先进行描述性统计分析。还使用二元逻辑回归分析评估与因变量相关的因素。
在这项研究中，在纳入分析的 456 位母亲中，有 360 位（78.9%）母亲有意使用短信提醒进行疫苗接种。其中，270 位（75%）希望在疫苗接种截止日期前一天收到提醒。年龄在 35 岁及以上的母亲（AOR=0.35；95%CI：0.15 至 0.83）、接受过中等或以上教育的母亲（AOR=4.43；95%CI：2.05 至 9.58）、手机使用时间（AOR=3.63；95%CI：1.66 至 7.94）、感知有用性（AOR=6.37；95%CI：3.13 至 12.98）和感知易用性（AOR=3.85；95%CI：2.06 至 7.18）是使用短信进行疫苗接种意愿的预测因素。
总之，大多数母亲都有意使用短信提醒来进行儿童疫苗接种。母亲的年龄、教育程度、手机使用时间、感知有用性和感知易用性与母亲使用短信进行疫苗接种的意愿有关。在开发和测试短信提醒系统之前，考虑这些预测因素和用户偏好是值得推荐的。
