We measured the performance of exposure screening questions to identify Nipah virus encephalitis in hospitalized encephalitis patients during the 2012-13 Nipah virus season in Bangladesh. The sensitivity (93%), specificity (82%), positive predictive value (37%), and negative predictive value (99%) results suggested that screening questions could more quickly identify persons with Nipah virus en...

This article shows that measurement invariance (defined in terms of an invariant measurement model in different groups) is generally inconsistent with selection invariance (defined in terms of equal sensitivity and specificity across groups). In particular, when a unidimensional measurement instrument is used and group differences are present in the location but not in the variance of the laten...

CONTEXT The Functional Movement Screen (FMS) is an assessment tool for quality of human movement. Research reports a significant difference between FMS scores of subjects who later experienced injury and those who remain uninjured. OBJECTIVE To systematically review literature related to predictive validity of the FMS. From the aggregated data, a meta-analysis was conducted to determine the p...

OBJECTIVE To measure the validity of safety behaviours, safety equipment use and hazards reported on a questionnaire by parents/carers with children aged under 5 years participating in a series of home safety case-control studies. METHODS The questionnaire measured safety behaviours, safety equipment use and hazards being used as exposures in five case-control studies. Responses to questions ...

OBJECTIVE To assess the validity of self-reported body mass index in the National Health Survey. METHODS 120 participants were selected and questioned about their weight and height with exactly the same questions that the National Health Survey uses. Afterwards, and once informed consent was obtained, participants were weighed and measured, and this data was used as the gold standard. RESUL...

This study evaluated the performance of the Rapidec Carba NP test, which was introduced recently into the market for the detection of carbapenemase production in a broad spectrum of β-lactamase-producing Enterobacteriaceae clinical isolates. In total, 252 clinical Enterobacteriaceae isolates that had been genetically characterized with respect to carbapenemase, extended-spectrum β-lactamase (ES...
