Use of Smartphones to Collect Information about Health Behaviors: Feasibility Study—New—National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP), Centers for Disease Control and Prevention (CDC).
Background and Brief Description
Despite the high level of public knowledge about the adverse effects of smoking, tobacco use remains the leading preventable cause of disease and death in the U.S., resulting in approximately 443,000 deaths annually. During 2005-2010, the overall proportion of U.S. adults who were current smokers declined from 20.9% to 19.3%. Despite this decrease, smoking rates are still well above Healthy People 2010 targets for reducing adult smoking prevalence to 12%, and the decline in prevalence was not uniform across the population. Timely information on tobacco usage is needed for the design, implementation, and evaluation of public health programs.
The evolution of completely new, completely mobile communications technologies provides a unique opportunity for innovation in public health. Text messaging and smartphone web access are immediate, accessible, and anonymous, a combination of features that could make smartphones ideal for the ongoing research, surveillance, and evaluation of risk behaviors and health conditions, as well as targeted dissemination of information.
CDC proposes to conduct a feasibility study to identify and evaluate the process of conducting surveys by text message and smartphone, the outcomes of the surveys, and the value of the surveys. The universe for this study is English-speaking U.S. residents aged 18-65. The sample frame will consist of a national random digit dial sample of telephone numbers from a frame of known cell phone exchanges. Respondents reached on their cell phones will be asked to complete an initial CATI survey consisting of a short series of simple demographic questions, general health questions, and questions about tobacco and alcohol use. At the conclusion of this brief survey, respondents who have smartphones will be asked to participate in the feasibility study, which consists of a first follow-up survey and, a week later, a second follow-up survey. Those who agree will receive invitations to participate by text message, which will include a link to the survey. A sample of respondents who do not have smartphones will be asked to participate in a text message pilot, which also consists of a first follow-up survey and a second follow-up survey. Text message respondents will receive a text message inviting them to participate; respondents opting in will be texted survey questions one at a time. Before initiating the feasibility study, CDC will conduct a brief pre-test of information collection forms and procedures.
This study will evaluate: (1) Response bias of a smartphone health survey by comparing data collected via CATI to data collected via smartphones/text messages, and data collected via smartphones to data collected via text messages, (2) relative cost-effectiveness of data collected via CATI to data collected via smartphones/text messages; (3) coverage bias associated with restricting the sample to smartphone users; and (4) the utility of smartphones for completing frequent, short interviews (e.g., diary studies to track activities or events).
OMB approval is requested for one year. Participation is voluntary and respondents can choose not to participate at any time. There are no costs to respondents other than their time. The total estimated annualized burden hours are 236.
