Very happy to see our paper with P. J. Lavrakas on Social-psychological Aspects of Probability-based Online Panel Participation published in International Journal of Public Opinion Research, especially since we demonstrated how qualitative data can be used to study non-response phenomena: doi.org/10.1093/ijpor/…

Our paper with Bernie Baffour on improving accuracy of Australian nonprobability online panel samples has been published in @gesis_ord's mda: doi.org/10.12758/mda.2…. While challenging, we showed how carefully designed post-survey adjustment can be successful in reducing bias.

Thrilled to see our meta-analysis (with @lkaczmirek) finally out! A thorough analysis of recruitment rates/practices in 28 probability-based online panels is now published in the International Journal of Social Research Methodology at doi.org/10.1080/136455… #Stats #survey

After a stimulating first day at #WAPOR23 conference, I'm excited to present tomorrow on post-survey adjustments aimed at mitigating representation bias in an academic volunteer online panel. WAPOR

A new day, a different country, a different conference, another presentation of my methods research. This time I have the privilege to talk about my PhD thesis research (Approaches to dealing with survey errors in online panel research) at #GOR23. DGOF

Another paper on motivations to participate in online panels with P.J. Lavrakas has just been published in Survey Practice. In this one, we present a method that could help improve representation for a very low cost by utilizing self-reported motivations: surveypractice.org/article/88139-…

Seriousness aside, "Understanding Australia" sounds more like a hybrid between SocialResearchCentre's Life in Australia (we used data from this online panel) and Understanding Society longitudinal survey (Understanding Society). I do like this blended name for a future study in Australia, though.🙂

Just published my final piece from my PhD thesis - the article on RDD text-to-web is now available in IJMR. It covers (almost) everything you need to know to implement text-to-web (with or without RDD) in practice. Read it here: doi.org/10.1177/147078…

New article from Sebastian Kocar on the investigation between wave communications that could serve as cost-effective panel maintenance activities to increase completion in panel surveys. Read it today. bit.ly/3UfcDs3

Our paper with PJ Lavrakas is now out in the International Journal of Market Research. We examine motivations & barriers to questionnaire completion in a nonprobability online panel, and identify five distinct psychographic profiles of panellists. More at doi.org/10.1177/147078…
