Measurement musing: Thinking about the ways we assess individuals (e.g. tests,interviews) & corresponding items/questions. As we consider processes to mitigate bias, I wonder about validity. Thread about response processes (i.e.what people do, think or feel when responding)1/10. 2/ RP are not only cognitive but also involve: motivation, behaviour, affect and intuition. What does this mean? Well, it means we need to look beyond a respondent's answers and consider contextual factors, as well as assessors (if involved) to understand how people respond.

Measurement validity is bonkers!🤨 Writing a thread here in response. Thnx @carole_lunny for the prompt! Starting w/ definition of validity. Need to consider validity as interpretations of test score use (ie.validity as "measuring what it is supposed to" has gaps in meaning). 1/9

2/ Article by @EikoFried and @JkayFlake is excellent...e.g. hidden invalidity is so on point. Text by Devellis (2017) is very good for scale development BUT ignore chapter on validity. ***Note: many texts use unreferenced validity theories and out-of-date notions of validity.
