A Mixture Unfolding Model for Insufficient Effort Responses

• In Event: Test Taking Effort and Careless Responding

Abstract

Insufficient effort responses, which can reduce reliability and validity, are often collected in surveys. Following the ideal-point approach, a mixture unfolding model is proposed that not only performs parameter estimation but identifies aberrant respondents. The simulation results showed good parameter recovery and high classification rates of the new model.
