  1. Tiaray Razafindranovona September 26th, 2013 The Philosophy of French experimentson Internet and mixed modes data collection

  2. Introduction • Better quality, more complexity … • … in a general context of budgetary reduction ! • Mixed modes to face these challenges ? • Experimental surveys will help to answer

  3. Principles of French experiments • An experiment for (almost) each new household survey • General results on mixed modes surveys not sufficient • Experiments in parallel of each new CAPI survey • No interference with main survey • Workload • Sampling frames • Each survey must test something new • Accumulation of experience • Test of new specific points not already handled

  4. Standard protocol • Sample frames • Name and adress for massmailing • Available in taxpayers files • Questionnaire • Fitted subset of the CAPI questionnaire • Length around 10/15 minutes • Notification letter, reminders • First, a postal mail with a notification letter • 2 reminders (one with paper questionnaire)

  5. Examples of experiments • Housing 2010 (Amiel and Denoyelle, 2012) • Comparison with results of Housing 2006 (face-to-face) • Internet respondents less satisfied (calibration techniques) • Safety survey (SASU) 2013 • First experimental survey on victimization • 2 protocols to control the problem of self-selection • Housing 2014 • Focus on rental amount • External documents without the interviewer ? • Wealth 2014 • Focus on value of real estate property • Deviations from market value without the interviewer ?

  6. Working conditions Quality of life at work (QLW) • Working conditions survey (face-to-face survey) Survey adresses many topics surrounding working conditions : • working hours and organization of working time • psychosocial constraints • relations with the public … • Experimental parallel survey : Quality of life at work Tackles same topics : shorter version of the questionnaire. Sample drawn in a base built on taxpayers files : only people that have declared earnings (in 2010) from work can be selected.

  7. QLW – Aims and protocols • Aims • Comparison of • Response rates between internet and internet+paper • Quality and content of responses between traditional and experimental surveys • Responses between 2 protocols involving different notification letters • Test questions of the future survey on psychosocial risks (2015) • Open questions to raise topics for this survey • Protocols • 2 different models of notification letters (psychosocial risks) • For half of the sample, internet and paper (standard protocol), for the other half, only internet

  8. QLW – Response rates At the end of the data collection Subsample 1 - model A letter, internet and paper available as modes of response Subsample 2 - model B letter, internet and paper available as modes of response Subsample 3 - model A letter and only internet available as mode of response Subsample 4 - model B letter and only internet available as mode of response (model B letter insists on psychosocial risks)

  9. QLW – Sample vs internet / paper Comparison on sample frame variables

  10. QLW – Internet vs paper respondants Comparison on survey variables

  11. QLW – Examples of mode effects • Differentiation on responses scale (satisficing) • Control of selection with kernel matching on propensity score • Index of response differentiation (McCarty and Shrum, 2000) • Result : differentiation more pronounced on internet than on paper • Emotional well-being • Control of selection with kernel matching on propensity score • WHO-5 well-being index (de Wit et al., 2007) • Result : emotional well-being higher on paper

  12. Conclusion • Mixed modes : adaptations to technological changes • Not to be forced without prior evaluation of quality • Future results of experiments will help to re-design • A standard scheme ? Trade-off with society requests
