Item response theory for measurement validity
Item response theory (IRT) is an important method of assessing the validity of measurement scales that is underutilized in the field of psychiatry. IRT describes the relationship between a latent trait (e.g., the construct that the scale proposes to assess), the properties of the items in the scale, and respondents' answers to the individual items. This paper introduces the basic premise, assum...
متن کاملFactor copula models for item response data.
Factor or conditional independence models based on copulas are proposed for multivariate discrete data such as item responses. The factor copula models have interpretations of latent maxima/minima (in comparison with latent means) and can lead to more probability in the joint upper or lower tail compared with factor models based on the discretized multivariate normal distribution (or multidimen...
متن کاملItem sampling in service quality assessment surveys to improve response rates and reduce respondent burden
Purpose – Survey researchers sometimes develop large pools of items about which they seek participants’ views. As a general proposition, library participants cannot reasonably be expected to respond to 100 þ items on a given service quality assessment protocol. This paper seeks to describe the use of matrix sampling to reduce that burden on the participant. Design/methodology/approach – Matrix ...
