Impact of Item Characteristics on Item Selection Procedures in Mokken Scale Analysis

• In Event: Electronic Board Session II

Abstract

We examined the impact of problematic item characteristics on the accuracy of item scale classifications based on automated selection procedures (AISP) in Mokken Scale Analysis (MSA). Although AISP was fairly robust to violation of invariant item ordering, results v monotonicity and scalability violations compromised the accuracy of scale assignment.
