SUMMARY:Conférence-midi du GRIÉMÉtic 'Response styles and aberrant respo
 nding in survey data'
DESCRIPTION:Conférence par Carl Falk\, professeur à l’Université McGi

(conférence en anglais)
Abstract: 
The use of Likert-type items is 
 pervasive throughout the social and behavioral sciences (e.g.\, rate your 
 agreement to a statement on a scale from 0 – Disagree to 4 – Agree). H
 owever\, individuals sometimes perceive and use the scale in different way
 s. In this talk\, I present an item response theory model capable of model
 ing multiple response styles across multiple constructs of interest. Some 
 features of this model include the ability for researchers to: 1) Flexibly
  determine how response styles are defined\, 2) Test whether modeling part
 icular response styles improves model fit\, 3) Obtain scores for participa
 nts on the constructs of interest and response styles\, and 4) Test for gr
 oup differences in the response styles or substantive constructs. Comparis
 ons with sum score-based approaches\, and recent extensions to multilevel 
 data will be briefly presented. Time permitting\, additional challenges in
  aberrant (atypical) responding to survey items will be discussed.
Biograp
 hy: Carl F. Falk is an assistant professor of Quantitative Psychology and
  Modeling in the Department of Psychology at McGill University. His work f
 ocuses on the development\, testing\, and computer programming of advanced
  latent variable models with applications across the social sciences (e.g.
 \, psychology\, education\, health outcomes\, sociology\, etc.). This work
  spans across item response theory\, structural equation modeling\, and mu
 ltilevel modeling. Recent applied work includes analysis of field test dat
 a and simulation based evaluations of item banks for the Smarter Balanced 
 Assessment Consortium.
