DESCRIPTION:Reactivity takes place when being measured or categorized affe
 cts a subject's attitudes and behaviour to such an extent that it affects 
 results in their (subsequent) measurement or categorization. Think\, for e
 xample\, of higher education institutions hiring temporary staff with the 
 sole purpose of receiving a higher score on performance indicators. Or con
 sider the effects that the act of filling out a quality of life survey may
  have on how a respondent ranks their quality of life compared to others. 
 Although researchers and methodologists commonly think of reactivity as a 
 source of measurement error\, this presentation shows that some quite extr
 eme reactive changes may be _legitimate_\, in the sense that the measureme
 nt results before and after the shift are both accurate to the measurand. 
 While the presentation starts from recent considerations in the psychometr
 ic literature on response shift\, it shows that these considerations canno
 t be extended easily to social scientific phenomena. To fill this gap in t
 he literature\, the presentation presents a tailored inventory of the diff
 erent types of reactivity in social scientific measurement\, as well as a 
 conceptual framework for distinguishing which type of reactivity is legiti
 mate\, based on specific properties we believe the measurand to have.
