Internet est très utilisé par les sondeurs pour produire des enquêtes rapides et à bas coût. Pour cela, les instituts ont mis en place de larges panels d’internautes volontaires, qui peuvent s’y inscrire par exemple par des bannières postées sur des sites populaires. Ces panels sont donc constitués sans base de sondage ni procédure probabiliste, alors même que plus de 20% des ménages n’ont pas accès à Internet en 2012 (Gombault, 2013). Le projet d’étude longitudinale par internet pour les sciences sociales (ELIPSS) a vu le jour pour permettre aux chercheurs de mener des enquêtes probabilistes sur des thèmes peu traités par la statistique publique française et de conduire des enquêtes longitudinales de grande ampleur, ordinairement hors d’atteinte de la recherche académique en sciences humaines et sociales. ELIPSS est un projet unique en France combinant le recrutement d’un panel probabiliste (représentatif) et son interrogation via un outil mobile connecté à Internet, une tablette tactile.

During the last decade, the internet has moved from an attractive data collection mode to a common way to administer surveys. The ELIPSS Panel (Étude longitudinale par internet pour les sciences sociales) is one of the probability-based web panels across Europe. This paper focuses on the lessons learned from the pilot study to set up the main panel. First, we will give an overview of the recruitment procedure planned for 2015 in the light of the pilot results. Then, we will present the specifications for the management of the panel to maintain monthly participation and limit attrition.

Présentation réalisée dans le cadre du séminaire commun SFDS et AFSP du 21 novembre 2013 intitulé "Analyses électorales. Dialogue entre statisticiens et politistes". Le dispositif ELIPSS de collecte par questionnaire sur internet permet de développer de nouvelles façons d'interroger les pratiques et les opinions dans la population résidant en France métropolitaine. L'utilisation pratique du dispositif est mise en lumière grâce à la présentation de l'enquête longitudinale Dynamob administrée au panel ELIPSS depuis 2013.

The ELIPSS Panel (Étude longitudinale par internet pour les sciences sociales) is a French probability-based web panel which is dedicated to surveys in social sciences. Its target population is the French population aged 18-79. Each panel member receives a touchscreen tablet equipped with a 3G/4G connection in order to participate in the self-administrated questionnaires. The monthly surveys are carried out from a specific application pre-installed on the tablet. From 2012 to 2015, the ELIPSS panel was in its pilot stage and is now on the main panel phase since 2016. The pilot was composed of more than 1000 panel members in 2012, 800 among them were still present in 2016. To complete the pilot sample, an offline recruitment of 2500 new panel members was carried out during the first semester of 2016. The questionnaires are designed by research teams after their survey project has been selected by the ELIPSS scientific and technical board. The surveys can be longitudinal or cross-sectional projects. In addition to these surveys, the ELIPSS team conducts each year one core survey to collect sociodemographic data and one survey on the digital practices and the equipment of the panel members. ELIPSS offers a unique opportunity to assess the panel conditioning. Firstly we can study of the evolution in answering of the panel members of the pilot on various topics such as political attitudes, leisure activities and cultural practices, report of socio-demographic characteristics and digital practices. In particular, we will study political attitudes batteries with randomly ordered items at several waves. We will also focus on the internet usage questions since one of the specific aspects of ELIPSS is to provide panel members with a touchscreen tablet connected to the internet. Exploratory results show that non-users of the internet at the entry in the panel became regular users one year after. Secondly, we will be able to compare the pilot sample attitudes and behaviours, which are experienced respondents, with the newly recruited members of the panel. Several waves of the survey on political attitudes and the core survey of ELIPSS are administered at the same time to the two samples in 2016 as well as in early 2017. This paper will address the issue of panel conditioning based on empirical evidences from longitudinal self-administered surveys conducted during four years.

During the last decade, the internet has moved from an attractive data collection mode to a common way to administer surveys. The ELIPSS Panel (Étude longitudinale par internet pour les sciences sociales) is one of the probability-based web panels across Europe. This presentation focuses on the challenges in setting up a probability-based web panel and the lessons learned from the pilot study. First, we will discuss the results of the recruitment procedure used in 2012. Then, we will point out the opportunities offered by ELIPSS to the researchers to collect data, and will present some examples of surveys using specific features of the tablet. Finally, we will address the issues of maintaining the participation and will present some specifications for the management of the panel. This paper was presented to the "Methods and research meetings" of the FORS research institute the 24th February 2015.
