Item Parameter Drift occurs over time for various reasons; when test items lose their initial characteristics, such as difficulty and discrimination parameters. Including cases of item parameter drift are revealed, excessive repetition, changes in the education system, and the position of items and the parameters of poor initialization. Item parameter drift causes of the invariance to be violat...
OBJECTIVE The aim of this study was to investigate unidimensionality and differential item functioning of the SF-36 physical functioning scale (PF10) in patients with various neurological disorders. PATIENTS PATIENTS post-stroke (n = 198), with multiple sclerosis (n = 151) and amyotrophic lateral sclerosis (n = 193) participated. METHODS Unidimensionality of the PF10 within the patient grou...

OBJECTIVE When comparing outcomes of the Functional Independence Measure (FIM ) between patient groups, item characteristics of the FIM should be consistent across groups. The purpose of this study was to compare item difficulty of the FIM in 3 patient groups with neurological disorders. SUBJECTS Patients with stroke (n=295), multiple sclerosis (n=150), and traumatic brain injury (n=88). ME...
