As item response theory (IRT) has developed and is widely applied, investigating the fit of a parametric model becomes an important part of the measurement process when implementing IRT. The usefulness and successes of IRT applications rely heavily on the extent to which the model reflects the...

Needle sharing contributes to the spread of the human immunodeficiency virus and other health concerns and remains a persistent problem among injection drug users. We determined whether needle sharing may be related to the discounting of the value of delayed outcomes. Outpatients in treatment...

Based on Kamatas item analysis model (2001), an extension for differential item functioning procedure was developed and the applicability was examined. The Kamatas item analysis model is a type of hierarchical generalized linear model for item analysis, in which items are considered as nested in...
