The choice of the right survey software for face to face interviews is crucial. Here are the most important features to consider when you choose the
CAPI survey software.APPs for offline survey
Not all survey software provides a solution for conducting face-to-face surveys, and even fewer offer offline capabilities. Be sure that the survey software you selected includes both these features and a dedicated APP for these purposes.
Compatible APP with all mobile devices
The APP must be compatible with the most common devices, such as smartphones and tablets, both Android and Apple, regardless of their OS version. Choosing a tool that offers an APP compatible with the most popular devices brings many advantages, such as the possibility of using interviewer-owned devices, or low-cost devices provided by the agency or organization conducting the research without offline survey.
APP you can download from Google Play or AppStore
Interviewers can independently download the APP to their own devices, eliminating the need to deploy pre-configured tablets or smartphones. This solution lowers costs as no investment is required to purchase dedicated devices.
Easy setup and good usability of the APP
When working with interviewers scattered throughout the territory, assisting them can become complicated and onerous. It is essential that the APP is easy to install and that the download of the questionnaire, the data collection, and the data synchronization are simple, even for interviewers not previously trained.
Mixed-mode surveys
CAPI methodology can often be used in conjunction with other methodologies, for example the
CATI methodology i.e.
phone surveys or the
CAWI methodology for
online surveys. For example, agents (CATI methodology) might preemptively schedule appointments via telephone with contacts and then conduct face-to-face interviews in place. Or, field interviewers recruit people to be interviewed by recording some data and then sending a link via email or SMS for the respondent to answer the questionnaire by themselves (CAWI methodology
Geolocation and background audio recording
The app must record the GPS location of each interview and background audio recording to allow supervisors to verify the authenticity of the interviews conducted.
Costs and sales model of the software
Some software charge for each face-to-face agent in addition to the main cost of the system. This does not allow for a scalable cost since the number of agents may change from project to project, or face-to-face survey projects can be sporadic, making the initial investment unjustified. Other software charge for the respondents’ APP. This is the most inconvenient solution as it complicates the download of the app. Other software, such as
IdSurvey, has a cost by completed interview and offer the offline survey APP for free. This solution allows a scalable solution with no fixed costs. In the case of IdSurvey, there are also no costs for the main interface.
