The Covid-19 pandemic has affected not only the health of populations but also their everyday social practices, transformed by orienting to risks of contagion and to health prevention discourses. This paper emanates from a project investigating the impact of Covid-19 on human sociality and more particularly the situated and embodied organization of social interactions. It discusses how Covid-19 impacts the design of ordinary actions in social interaction, how this is made publicly accountable by the participants orienting to the pandemic in formatting their actions and in responding to the actions of others. Adopting an ethnomethodological and conversation analytic perspective, the analyses focus on a particular social activity: paying. The organization of payments in shops and services has been affected by the pandemic, not only by official regulations, favoring some modes of payment over others, but also in how sellers and customers situatedly adapt their practices to imperatives of prevention. On the basis of a rich corpus of video-recorded data, which spans from the pandemic’s prodromes to and after its peak, we show how money transfer is methodically achieved – imposed, negotiated, and readjusted – while variously taking into account possible risks of contagion. Thus, we show not only how pandemics affect social interaction, and how prevention is incarnated in social actions, but also how, in turn, situated solutions implemented by people during the pandemic reveal fundamental features of human action.

Using multimodal conversation analysis this article examines embodied and tactile greetings in social interaction, documenting their change during the Covid‐19 pandemic. Recognizing social interaction as foundational for human sociality, we consider greetings as a crucial normative, organizational, and ritual practice for mutually engaging in intersubjective action. Analyses use video recordings made in Switzerland (featuring (Swiss‐)German and English as a lingua‐franca), focusing on embodied greetings of acquainted people in public spaces at the age of Covid19—a historical moment in which physical proximity and contact are targeted by official measures restricting social interactions. Studying a range of tactile embodied greetings, the paper shows how they change from routine greetings to hesitated, suspended yet still completed ones, and to projected but resisted and refused ones. Furthermore, it reveals some ‘new’ practices of greeting (elbow/feetbumps, hugs‐in‐the‐air) and their non‐straightforward and accountable character, as well as how they sediment and normalize during the pandemic.

There is a need to improve the validity, reliability, and replicability of social and health science research and its applications through raising the quality of measurement. An important step is to establish and implement a clear and useful standard for reporting and assessing psychometric properties of measures. We propose five basic criteria as a minimal checklist to help end users assess the quality of psychometric studies: unidimensionality; ordered response categories, invariance; targeting; and, contingent upon the previous four being fulfilled, reliability. An expanded and detailed reporting guideline is also presented, intended for use in reports and scientific publications of psychometric analyses. Additionally, we present a freely available R package to streamline psychometric analysis with Rasch Measurement Theory and its documentation in line with the reporting guideline.
