Description

Cat object containing item parameters for graded response model fit with responses to the 20 item machiavellianism inventory

Usage

data(mach_cat)

Format

An object of class Cat of length 1.

Details

Cat object containing item parameters for graded response model fit with 3020 response profiles collected by Qualtrics in June 2018 and 12299 response profiles collected by the Open Source Psychometrics Project in 2012.

See Cat-class for details regarding the Cat object structure. See grmCat for details regarding the graded response model.

A normal prior was chosen with mean from the theta estimates from the Qualtrics sample (-0.713) and a standard deviation (1) wide enough to envelope the range of estimated theta values across both samples.

Note that due to how the item parameters were estimated, large, positive values indicate "more" of the latent trait.

Response options are: 5 = Strongly agree, 4 = Somewhat agree, 3 = Neither agree nor disagree, 2 = Somewhat disagree, 1 = Strongly disagree

The wording of the item responses is:
