BACKGROUND: Psychological constructionist models like the Conceptual Act Theory (CAT) postulate that complex states such as emotions are composed of basic psychological ingredients that are more clearly respected by the brain than basic emotions. The objective of this study was the construction and initial validation of Emotion Knowledge measures from the CAT frame by means of an invariant measurement approach, the Rasch Model (RM). Psychological distance theory was used to inform item generation...

BACKGROUND: Rasch analysis with a focus on Differential Item Functioning (DIF) is increasingly used for examination of psychometric properties of health outcome measures. To take account of DIF in order to retain precision of measurement, split of DIF-items into separate sample specific items has become a frequently used technique. The purpose of the paper is to present and summarise recent advances of analysis of DIF in a unified methodology. In particular, the paper focuses on the use of analysis of variance (ANOVA) as a method to simultaneously detect uniform and non-uniform DIF, the need to distinguish between real and artificial DIF and the trade-off between reliability and validity...

BACKGROUND: School attainment tests and Cognitive Abilities Tests are used in the United Kingdom to set targets for educational outcome. Whilst these are good predictors, they depend not only on basic ability but also on learnt knowledge and skills, such as reading. METHOD AND AIMS: VESPARCH is an online group test of verbal and spatial reasoning, which we propose gives a measure that more closely approximates to basic ability - fluid intelligence. The verbal test contains highly familiar words, does not require the child to read them, is untimed, and provides detailed feedback on five practice questions for each part of the test...

PURPOSE: Left ventricular outflow tract (LVOT) dimensions are important for calculation of aortic valve areas and planning of valve repair. Mostly, LVOT areas are calculated from echocardiographic longitudinal measurements with the assumption of a round shape. Here, orthogonal phase contrast (PC) MRI with dynamic assessment of LVOT was compared to standard longitudinal cine MRI and 2D echocardiography. METHODS: In 19 patients with aortic stenosis (5 female; 69±10years), LVOT areas were determined on orthogonal PC images, either by planimetry (Aplan) or by two-diameter measurement (Aellip)...

BACKGROUND: Motor Cortex Stimulation (MCS) was introduced in the early 1990's by Tsubokawa and his group for patients diagnosed with drug-resistant, central neuropathic pain. Inconsistencies concerning the details of this therapy and its outcomes and poor methodology of most clinical essays, divide the neuromodulation society worldwide in "believers" and "non-believers". A European expert meeting was organized in Brussels, Belgium by the Benelux Neuromodulation Society (BNS)in order to develop uniform MCS protocols in the pre-, intra- and post-operative course...
