Use case for the DDI representation of variables in repetitive contexts

Introduction

In 2012, the Center for socio-political data (CDSP) set up the ELIPSS (Longitudinal Online Survey for the Social Sciences) Panel, an online survey instrument addressed to the academic community. It is a probability panel based on a sample of around 2,600 respondents who every month complete online questionnaires designed by social science research teams.

General description

ELIPSS has a yearly core questionnaire (the Annual survey) to update sociodemographic data on panelists. Then, each month a new research survey is collected on a specific topic. The monthly survey can be cross-sectional (one-shot, for instance: fertility and birth control) or an additional wave of a longtudinal project (ex. Digital practices (wave 9)).

Sources and variables

  • Data files are shared with the research community based on:
    • annual survey only
    • longitudinal survey + data extracted from annual survey
    • cross-sectional survey + data extracted from annual survey
