BACKGROUND
Rather than providing participants with study-specific data collection devices, their personal mobile phones are increasingly being used as a means for collecting geolocation and ecological momentary assessment (EMA) data in public health research.
OBJECTIVE
The purpose of this study was to (1) describe the sociodemographic characteristics of respondents to an online survey screener assessing eligibility to participate in a mixed methods study collecting geolocation and EMA data via the participants' personal mobile phones, and (2) examine how eligibility criteria requiring mobile phone ownership and an unlimited text messaging plan affected participant inclusion.
METHODS
Adult (≥18 years) daily smokers were recruited via public advertisements, free weekly newspapers, printed flyers, and word of mouth. An online survey screener was used as the initial method of determining eligibility for study participation. The survey screened for twenty-eight inclusion criteria grouped into three categories, which included (1) cell phone use, (2) tobacco use, and (3) additional criteria.
RESULTS
A total of 1003 individuals completed the online screener. Respondents were predominantly African American (605/1003, 60.3%) (60.4%), male (514/1003, 51.3%), and had a median age of 35 years (IQR 26-50). Nearly 50% (496/1003, 49.5%) were unemployed. Most smoked menthol cigarettes (699/1003, 69.7%), and had a median smoking history of 11 years (IQR 5-21). The majority owned a mobile phone (739/1003, 73.7%), could install apps (86.8%), used their mobile phone daily (89.5%), and had an unlimited text messaging plan (871/1003, 86.8%). Of those who completed the online screener, 302 were eligible to participate in the study; 163 were eligible after rescreening, and 117 were enrolled in the study. Compared to employed individuals, a significantly greater proportion of those who were unemployed were ineligible for the study based on mobile phone inclusion criteria (P<.001); yet, 46.4% (333/717) of the individuals who were unemployed met all mobile phone inclusion criteria.
CONCLUSIONS
Inclusion criteria requiring participants to use their personal mobile phones for data collection was not a major barrier to study participation for most respondents who completed the online screener, including those who were unemployed.

背景
在公共卫生研究中，越来越多地使用参与者的个人手机来收集地理位置和生态瞬时评估（EMA）数据，而不是为参与者提供特定研究的数据收集设备。
目的
本研究的目的是（1）描述在线调查筛选器的受访者的社会人口学特征，该筛选器用于评估参与一项通过参与者个人手机收集地理位置和EMA数据的混合方法研究的资格，以及（2）研究要求拥有手机和无限短信套餐的资格标准如何影响参与者的纳入。
方法
通过公共广告、免费周报、印刷传单和口碑招募成年（≥18岁）每日吸烟者。在线调查筛选器被用作确定研究参与资格的初始方法。该调查筛选了分为三类的28项纳入标准，包括（1）手机使用情况、（2）烟草使用情况和（3）其他标准。
结果
共有1003人完成了在线筛选。受访者主要是非洲裔美国人（605/1003，60.3%）（60.4%），男性（514/1003，51.3%），中位年龄为35岁（四分位间距26 - 50）。近50%（496/1003，49.5%）失业。大多数人吸薄荷醇香烟（699/1003，69.7%），中位吸烟史为11年（四分位间距5 - 21）。大多数人拥有手机（739/1003，73.7%），能够安装应用程序（86.8%），每天使用手机（89.5%），并且有无限短信套餐（871/1003，86.8%）。在完成在线筛选的人中，302人有资格参与研究；163人在重新筛选后有资格，117人被纳入研究。与就业人员相比，基于手机纳入标准，失业者中不符合研究资格的比例显著更高（P <.001）；然而，46.4%（333/717）的失业者符合所有手机纳入标准。
结论
要求参与者使用个人手机进行数据收集的纳入标准，对于大多数完成在线筛选的受访者，包括失业者，并不是参与研究的主要障碍。
