OBJECTIVE To analyze the psychometric properties of the Token test (TT), a verbal comprehension test, and its applicability to the diagnosis of mild Alzheimer's disease (AD). METHODS One hundred and sixty participants (80 AD and 80 controls) performed the TT and a short battery of neuropsychological tests designed to evaluate general cognitive status, working memory and executive functions. I...

Empirical research focusing on personality disorders (PDs) among older adults is mainly limited to studies on psychometric properties of age-specific personality tests, the age neutrality of specific items/scales, and validation of personality inventories for older adults. We identified only two treatment studies-one on dialectical behavior therapy and one on schema therapy-both with promising ...

This paper describes 2 studies that evaluated a new instrument, the Perceived Ethnic Discrimination Questionnaire–Community Version (PEDQ-CV). The PEDQ-CV can be used across ethnic groups to assess perceived racism or ethnic discrimination. The scales measure several subdimensions of racism, permitting the examination of different forms of this race-related stressor. The first study evaluated t...

The paper presents a straightforward extension of the Bradley–Terry–Luce model (BTL model) that can be derived from the logistic threshold model of psychophysics which assumes that psychometric functions are logistic probability functions. It is shown that (under weak side conditions) the logistic threshold model is a submodel of the extended BTL model. Moreover, representation and uniqueness t...

Background: Introduced in June 2012, the phonics screening check aims to assess whether 6-year-old children are meeting an appropriate standard in phonic decoding and to identify children struggling with phonic skills. Aims: We investigated whether the check is a valid measure of phonic skill and is sensitive in identifying children at risk of reading difficulties. Sample: We obtained teacher a...

Previous research has established that social anxiety occurs at different rates in African American and European American populations (Grant et al., 2005), while psychometric investigations of widely used measures of psychopathology show differences in factor structure based on ethnic background (Carter, Miller, Sbrocco, Suchday, & Lewis, 1999; Chapman, Williams, Mast, & Woodruff-Borden, 2009)....

The current study examined the psychometric properties of the Brief Negative Symptom Scale (BNSS), a next-generation rating instrument developed in response to the NIMH sponsored consensus development conference on negative symptoms. Participants included 100 individuals with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder who completed a clinical interview designed to assess ne...

―This paper proposes a simplification of the method of transitions, which is used for the determination of the individual points of subjective equality from data obtained by the methods of constant stimuli or of paired comparisons. It is suggested that the estimated probabilities of transitions should no longer be computed from the psychometric function derived from the normal distribution func...

Decision making is an area of health research that has gained importance both for the partnership models of care that give prominence to the patient and family, either by growing concern about quality and customer satisfaction with the care provided. So we decided to make the cultural adaptation and to evaluate the psychometric properties of the Portuguese version "The Satisfaction with Decisio...

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...
