The construct validity of Rorschach Comprehensive System (CS) variables theoretically linked to alexithymia was evaluated in 92 outpatients with inflammatory bowel disease, 32 of whom were categorized as alexithymic, 15 as indeterminate-alexithymic, and 45 as nonalexithymic, on the basis of Toronto Alexithymia Scale scores. Six sets of Rorschach CS marker variables were selected for analysis: f...

We sought to validate the psychometric properties of a recently developed paradigm that aims to measure salience attribution processes proposed to contribute to positive psychotic symptoms, the Salience Attribution Test (SAT). The "aberrant salience" measure from the SAT showed good face validity in previous results, with elevated scores both in high-schizotypy individuals, and in patients with...

Reasoning Test The ART was developed by Embretson (1995) using the cognitive design system approach. ART items are matrix completion problems. Matrix completion problems appear on a variety of intelligence and ability tests. They are considered a stable measure of fluid intelligence (Raven, 1965). Construct Validity and Cognitive Diagnostic Assessment 133 Embretson (1995, 1998) further develope...

Establishing adequacy of psychometric properties of an instrument involves acquisition and evaluation of evidence based on item content and internal structure. Content validity evidence consists of subject matter experts providing quantitative ratings of the extent to which items are a representative sample of targeted domain. Evidence of internal structure includes factor analytic studies and ...

This report examines the construct of information systems quality. It is measured with the use of four questionnaire items that elicit perceptions of quality from the end users of the information system. These items query the level of functionality, information sufficiency, response time, flexibility, ease of use and overall quality of the system. The representational assumptions of the instrum...

Confirmatory factor analysis method is usually used in psychological surveys to evaluate the construct validity. But most of the researchers have been wasting their resources (e.g. effort, time, money) without power analysis at the beginning of their studies. The main purposes of this study are to analyze the statistical power, to estimate sample size for the confirmatory factor analysis model ...

The aim of this study was to assess the construct validity of the Adolescent Resilience Scale which measures the psychological features of resilient individuals. Research involving this scale, the Negative Life Events Scale, and the General Health Questionnaire was conducted with a group of 207 Japanese undergraduate students (104 men and 103 women; M age=20.2 yr., SD=.9). A cluster analysis fo...

Construct validity is one of the most central concepts in psychology. Researchers generally establish the construct validity of a measure by correlating it with a number of other measures and arguing from the pattern of correlations that the measure is associated with these variables in theoretically predictable ways. This article presents 2 simple metrics for quantifying construct validity tha...

The multitrait-multimethod matrix approach as proposed by Campbell and Fiske (1959) was an important contribution to our understanding of the nature of validation procedures. There are, however, problems encountered when using the Campbell and Fiske (1959) approach. The purpose of this article is to discuss the method and selected problems, and to propose an alternate approach to address those ...
