There is considerable variation between male and female Bachelor degree performance at Oxford and Cambridge (Oxbridge) where male students attain more First and Third Class degrees and female students attain more Second Class degrees. Various hypotheses have been put forward to explain this phenomenon including the possibility that the distinctive…

The Symptom Validity Scale (Minnesota Multiphasic Personality Inventory-2-FBS [MMPI-2-FBS]) is a standard MMPI-2 validity scale measuring overstatement of somatic distress and subjective disability. Some critics assert the MMPI-2-FBS misclassifies too many medically impaired persons as malingering symptoms. This study tests the assertion of…

In Taiwan, promoting knowledge of "Labor Safety" which relates to life and work right is very important. Safety training and learning effectiveness become essential issues of adult learning. To reduce the costs of educational training, enterprises have also started to aggressively introduce e-learning education training. Unlike the…

Objectives: The Trauma Resilience Scale (TRS), assessing protective factors associated with positive adaptation following violence, was tested in three waves of data collection. Empirical and theoretical literature shaped subscale and item formation emphasizing resilience following physical abuse, sexual abuse, intimate partner violence, and/or a…

The standard errors of the 2 most widely used population-invariance measures of equating functions, root mean square difference (RMSD) and root expected mean square difference (REMSD), are not derived for common equating methods such as linear equating. Consequently, it is unknown how much noise is contained in these estimates. This paper…

Among the many methods available for modeling intraindividual time series, differential equation modeling has several advantages that make it promising for applications to psychological data. One interesting differential equation model is that of the damped linear oscillator (DLO), which can be used to model variables that have a tendency to…

The current main world university rankings broadly group the leading research universities of nations. Australia's Go8 universities are generally within the top 250 ranked universities, with several institutions in the top 50-100 on some measures. This recognition is commendable, however imperfect the individual rankings may be. Use is made of…

Investigating the fit of a parametric model is an important part of the measurement process when implementing item response theory (IRT), but research examining it is limited. A general nonparametric approach for detecting model misfit, introduced by J. Douglas and A. S. Cohen (2001), has exhibited promising results for the two-parameter logistic…

The impact of socially desirable responding or faking on noncognitive assessments remains an issue of strong debate. One of the main reasons for the controversy is the lack of a statistical method to model such response sets. This article introduces a new way to model faking based on the assumption that faking occurs due to an interaction between…

Using generalizability theory to evaluate the reliability of child and adolescent measures enables researchers to enhance precision of measurement and consequently increase confidence in research findings. With an observer-rated measure of child self-regulation, we illustrate how multiple sources of error variance (e.g., raters, items) affect the…

The Mayer, Salovey, & Caruso Emotional Intelligence Test (MSCEIT) has been reported to provide reliable scores for the four-branch ability model of emotional intelligence [Mayer, J. D., Salovey, P., & Caruso, D. R. (2002). "Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT). User's manual." Toronto, Canada: Multi-Health…

The aim of this study is to assess the effective measurement range of Ryff's Psychological Well-being scales (PWB). It applies normal ogive item response theory (IRT) methodology using factor analysis procedures for ordinal data based on a limited information estimation approach. The data come from a sample of 1,179 women participating in a…

Aim: This study investigated the reliability and validity of the Barry-Albright Dystonia Scale (BADS), the Burke-Fahn-Marsden Movement Scale (BFMMS), and the Unified Dystonia Rating Scale (UDRS) in patients with bilateral dystonic cerebral palsy (CP). Method: Three raters independently scored videotapes of 10 patients (five males, five females;…

Background: The differentiation hypothesis posits that the underlying liability distribution for psychopathology is of low dimensionality in young children, inflating diagnostic comorbidity rates, but increases in dimensionality with age as latent syndromes become less correlated. This hypothesis has not been adequately tested with longitudinal…

We are currently at an exciting juncture in developing effective means for assessing so-called 21st-century skills in an innovative yet reliable fashion. One of these avenues leads through the world of "epistemic games" (Shaffer, 2006a), which are games designed to give learners the rich experience of professional practica within a discipline.…
