Abstract Background This study investigated the ArmA-TH sub-scale measurement properties based on item response theory using Rasch model. Methods Patients with upper limb hemiplegia resulting from cerebrovascular and other brain disorders were asked to complete questionnaire. analysis was performed test how well passive active function sub-scales fit model by investigating unidimensionality, ca...

A recent study of the Five Facet Mindfulness Questionnaire reported high levels of differential item functioning (DIF) for 18 of its 39 items in meditating and nonmeditating samples that were not demographically matched. In particular, meditators were more likely to endorse positively worded items whereas nonmeditators were more likely to deny negatively worded (reverse-scored) items. The prese...

Differences in performance of native and foreign students reading comprehension mathematics emerge all standardised assessments, both at national international levels. This study is the continuation a previous research project which we examined citizenship-based differences Italian item level connection with students’ competence text comprehension. We present deeper analysis items presented sig...

This study applied the odds-ratio (Penfield, 2008), the multinomial logistic regression (Kato et al., 2009), and the standardised distractor analysis (Schmitt and Bleistein, 1987) methods in the examination of differential distractor functioning (DDF) effects. Using data from the administration of one statewide mathematics assessment, these methods were applied to provide insight into two resea...

The Wisconsin Schizotypy Scales are widely used for assessing schizotypy in nonclinical and clinical samples. However, they were developed using classical test theory (CTT) and have not had their psychometric properties examined with more sophisticated measurement models. The present study employed item response theory (IRT) as well as traditional CTT to examine psychometric properties of four ...

The present research presents a detailed psychometric analysis of the Biographical Inventory Creative Behaviors (BICB), 34-item yes/no checklist common that has become one most popular measures behaviors.

BSD was measured with six self-disclosure topic items—in which higher scores indicated greater willingness to engage in conversations about various topics—from three groups with varying experiences with intercultural friendships. Confirmatory factor analysis was us...

BACKGROUND Previous studies have analyzed the psychometric properties of the World Health Organization Disability Assessment Schedule II (WHO-DAS II) using classical omnibus measures of scale quality. These analyses are sample dependent and do not model item responses as a function of the underlying trait level. The main objective of this study was to examine the effectiveness of the WHO-DAS II...

The impact of curricular reform efforts that are incorporated into the Statewide Systemic Initiatives (SSIs) program were examined at the item level using data from the 1990, 1992, and 1996 NAEP state administrations. The item-level data from the State NAEP for grade 8 from 1990, 1992, and 1996 and for grade 4 from 1992, and 1996 were examined applying methodology developed for the study of dif...
