STUDY DESIGN This was a prospective observational study of patients with low back pain and those without after laminotomy and discectomy. OBJECTIVES To determine, using a strict experimental design, the relative pain intensity response to provocative discography in symptomatic and asymptomatic subjects after lumbar discectomy for intervertebral disc herniation. BACKGROUND Provocative discog...

It has recently been pointed out by several authors that the psychometric assessment of the elderly patient has largely been geared to, or preoccupied with, the solution of diagnostic problems, measuring deterioration or discover ing early dementia (Post, 1966; Inglis, :962). Therefore, it appears that little attention has been paid to the use of psychometric tests in the broad area of prognosi...

Objective: Various studies on personality in SE have found large, small or no effects and there is no consensus on the importance of psychometric measurements in SE. There is also a lack of studies employing other psychometric instruments or using larger datasets. We aim to evaluate our results in a larger sample, with software engineers in an earlier state of their career, using advanced stati...

The psychometric function relates an observer's performance to an independent variable, usually some physical quantity of a stimulus in a psychophysical task. This paper, together with its companion paper (Wichmann & Hill 2000), describes an integrated approach to (1) fitting psychometric functions, (2) assessing the goodness-of-fit, and (3) providing confidence intervals for the function’s par...

aim and background: self-assertiveness is one of the ten life skills and its achievement is necessary in order to have a good and favorable life. precise measurement of these features and decision-making are necessary to promote it; therefore, the present study aimed to construct and review the quality of psychometric assessment of self-assertiveness scale in students of isfahan university of m...

Research suggests that Claustrophobia, defined as the fear of enclosed spaces, may be better conceptualized as two separate, but related fears: (1) the fear of suffocation, and (2) the fear of restriction. The Claustrophobia Questionnaire (CLQ) is a self-report measure designed to assess these two fears. The original English version of the CLQ has demonstrated excellent psychometric properties....

Mental illness is associated with unfair treatment in a number of areas of life. There is currently no psychometrically validated measure that has been developed to specifically focus on such experienced discrimination. This study aimed to finalise the Discrimination and Stigma Scale (DISC) and establish its psychometric properties. The DISC was further developed using (1) service user and inte...

Neuropsychological profiles were assessed in a large group of nondemented control subjects (n = 261) and individuals with dementia of the Alzheimer type (DAT) (n = 407) by subjecting their psychometric test results to a factor analysis. Nondemented control subjects were functionally homogeneous with only one factor accounting for the results. The results of the factor analysis on the very mild ...

Background: Schairer and colleagues hypothesized that the slope of any psychometric function for forward-masked probe-tone detection depends upon the standard deviation of an external Gaussian input distribution of probe-tone intensities, which in turn reflects the coupling of an internal Gaussian output distribution to the cochlear mechanical nonlinearity. The latter was postulated to have two...
