Interviewer

Interface Localization

The Interviewer application responds to the device language setting of tablets. Localization affects the interface of the application, such as menus, dialogs and application error messages. The languages currently supported are: English French Spanish Portuguese Russian Thai Indonesian Khmer Chinese Arabic Romanian Note that you can still design the questionnaire itself in any language, including the texts of the questions, their options, instructions, and validation messages.

Questionnaire Interface & Answering Questions

Overview of Questionnaire Interface  Answering questions How to know when you have answered a question   There are a few ways that interviewers can know that they have successfully answered a question. First, the question shows some answer. Second, the tablet vibrates and the questions are surrounded by a red outline, if the recorded answer is not valid. Vibration can be disabled by navigating to Interviewer’s settings and removing the checkbox next to Vibrate when invalid answer is given.

Answering All Question Types

The Interviewer application allows several different types of questions: numeric, text, single-select categorical, multi-select categorical, list, date, GPS, barcode, and picture. As an interviewer, you must know how to answer each of them. To help you with that text, each question type is briefly explained below with visual aids.  Numeric Questions that take a numeric response have a field for an open numeric answer. When that field is tapped, the numeric keyboard appears so that the interviewer can compose an appropriate numerical response.

Comments

Comments can be left for any question. This may useful to explain answers that you have confirmed but that may appear strange or wrong to your supervisor. To leave a comment, press for a moment on the question of interest. After a few seconds, a comment field will appear, into which you can type any arbitrary long comment. Comments can also be left for you by your supervisor. These will likely be questions about the answers you have recorded.

Moving Around the Questionnaire

Overall Interviewers should strictly follow the survey protocol for administering a questionnaire (e.g. asking earlier questions before later questions, completing earlier modules before later modules), but may occasionally need to move around the questionnaire for good reasons (e.g. review their work, move between rows of the roster if the respondent corrects an earlier answer, administer an independent module when the key respondent for that module is present). The interviewer can move around questionnaires in several ways.

Quality Control & Marking Interviews as Complete

Checking whether all questions have been answered Quality control starts with the interviewer. The interviewer should thus do everything within their power to ensure that all questions are answered. The interviewer application offers three ways to do this. The first is the classic method that one might use with a paper questionnaire. The interviewer simply flips the questionnaire looking for unanswered questions or answers that have triggered red error messages.

Synchronization

Sending completed interviews and receiving new ones The synchronization button is how the interviewer initiates an information exchange between their tablet and their supervisor’s laptop. Synchronization performs two tasks. First, it automatically pushes any completed assignment to the supervisor for review. Second, it automatically pulls all new assignments and data collection instruments onto the interviewer’s tablet. After synchronization is complete, the number of new assignments received, number of completed interviews sent, and so on are clearly displayed.

Troubleshooting

Diagnostics The diagnostics button provides a number of options for troubleshooting problems with synchronization. Under this menu you can: Check for updates to the interviewer application Test your network connection Manually back up the data collected to Headquarters Create a backup of data collected on the tablet device Share device specifications and information These actions are not typically taken by the interviewer, but rather by the supervisor or the surveys technical support in the case of troubleshooting problems on a particular tablet.

Consequences of relinking a tablet device

When an interviewer account is created at the HQ, an interviewer may connect from any tablet. Once the interviewer has signed in, that device ID is remembered and the interviewer must continue using the same tablet. No other interviewer will be permitted to use the same device: they will not be able to enter their username unless the interviewer app is uninstalled (with immediate loss of all unsynchronized data). It is not possible for one user to work on several devices.

Setting photo size and quality

Survey Solutions v5.22 automatically restricts the size of the images captured by the Interviewer App (see limits). The information below is applicable only if you wish to produce files even smaller than those automatically produced. Survey Solutions image (picture) question does not specify any particular size or quality of the photo to be captured with the tablet’s camera. Instead Survey Solutions captures the image supplied by a standard picture provider (typically the Camera application) installed in the OS Android.
