Evaluating the extent fit Hypomania Scale items to one and Two parameter models

Abstract

The aim of the current research is to reveal the extent to which the hypomania scale items conform to the assumptions of the one- and two-parameter models. To achieve the objectives of the study, the one- and two-parameter models were used in grading the hypomania scale from the Minnesota Multifaceted Personality Test MMPI-2, second edition, and then testing the effect of two variables ( The one- and two-parameter model used, sample size 300, 2700) in the grading results, and the extent of agreement between the two models, using accuracy measures represented by the standard error, information function, and reliability. The number of sample members was (3000) male and female third-year students from the University of Damascus in all its specializations. The results indicated agreement between the one- and two-teacher model on the exclusion of two items from the hypomania scale. The two-parameter model is more appropriate than the one-parameter model. Sample size (2700) is better using the two-parameter model according to accuracy criteria.
