aim and background: in this study, the psychometric properties and hierarchal structural validity of short form health survey scale (sf-36) among students using structural equating modeling was investigated. methods and materials: a sample with 310 students (158 male and 152 female) from tehran university were chosen by multistage sampling method. for verifying discernment validity, two clinica...

Consider combining several elementary detectors by the extreme decision rule of responding "no" only when all elementary detectors respond "no" and "yes" otherwise. The question raised is: Which psychometric functions for the detectors have the property that the resulting psychometric function is simply the original function displaced in the logarithm of the physical scale? The answer is p(I) =...

The focus of the study is on the assessment of readability for prevailing America and Chinese English textbooks with the measurement software and systems. The result indicated college reading textbooks produced by Chinese publishers seemed to vary in level, with some texts above the reading ability of most college students. Then simplification strategies used to make Chinese EFL reading texts m...

The aim was to critically appraise the methodological quality of studies and determine the psychometric qualities of Past-week and Usual-week Physical Activity Questionnaires (PAQs). Data sources were obtained from Pubmed and Embase. The eligibility criteria for selecting studies included: 1) at least one psychometric property of PAQs was examined in adults; 2) the PAQs either had a recall peri...

Recent research suggests a functional link between temporal acuity and general intelligence. To better understand this relation, the present study took advantage of a large sample (N=260) and structural equation modelling to examine relations among temporal acuity, measured by various tasks, speed of information processing as measured by the Hick reaction time task, and psychometric intelligenc...
