In this paper, the authors report research focused directly on the validation of the Coding of Academic Teacher-Student interactions (CATS) direct observation instrument. They use classroom information gathered by the CATS instrument to better understand the potential mediating variables hypothesized to influence student achievement. Their study's…

The primary objective of this study was to develop an instrument to measure adults' attitudes toward continuing education. Secondary objectives consisted of various statistical analyses designed to provide preliminary evidence of the instruments' criterion-related and construct validity. (JOW)

This study examined the factors that influence consumer satisfaction with mobile telephone use in Malaysia. The validity of the study's constructs, criterion, and content was confirmed. Construct validity was verified through the factor analysis with a total variance of 73.72 percent explained by all six independent factors. Content validity was…

For many years, medical students at the University of Sydney undertook their clinical clerkships in traditional metropolitan teaching hospitals, which were regarded as the "gold standard" for clinical training. In 2001 the university established a rural clinical school at which increasing numbers of students now complete a significant…

Item and factor analyses examined the psychometric characteristics of the White Racial Identity Attitude Scale based on data from 308 white college students. Then five trained judges assigned scale items to appropriate subscales. Results did not support the psychometric adequacy of the scale. (SK)

Describes a short-form assessment scale for drug involvement, providing information about its administration, scoring, and interpretation. Discusses the initial research conducted to validate the instrument and provides reliability data. Also details the development of a clinical cutting score that will help practitioners evaluate the significance…

Objective: Assess validity of the ecSatter Inventory (ecSI) to measure eating competence (EC). Design: Concurrent administration of ecSI with validated measures of eating behaviors using on-line and paper-pencil formats. Setting: The on-line survey was completed by 370 participants; 462 completed the paper version. Participants: Participants…

The authors developed and validated a measure of teachers' motivation toward specific work tasks: The Work Tasks Motivation Scale for Teachers (WTMST). The WTMST is designed to assess five motivational constructs toward six work tasks (e.g., class preparation, teaching). The authors conducted a preliminary (n = 42) and a main study among…

A validation strategy is proposed for professional licensure tests after reviewing arguments for incorporating a theory of professions into the test development process. Components of such a theory are described, and a methodology is proposed for licensure test design that balances the concepts of content and construct validation. (SLD)

Validated data from a developmental mathematics assessment using classical and three-faceted Rasch measurement methods. Analysis of field test data for 289 elementary school students suggested that a unidimensional construct was being measured, as defined by Rasch criteria. Discusses limitations in confirming content-related validity of the…

This article presents a methodology for examining the content and nature of item parcels as indicators of a conceptually defined latent construct. An essential component of this methodology is the 2-facet measurement model, which includes items and parcels as facets of construct indicators. The 2-facet model tests assumptions required for…

The "Multidimensional Attitudes toward Inclusive Education Scale" (MATIES) was developed to effectively measure affective, cognitive and behavioural aspects of attitudes, within the realm of inclusive education that includes physical, social and curricular inclusion. Models within Item Response Theory and Classical Test Theory were used…

A multicultural awareness scale completed by 72 nursing students obtained a Cronbach's alpha reliability coefficient of .91. An expert panel analyzed content validity and the revised scale was completed by 118 students. Factor analysis supported the measure's construct validity. (Contains 30 references.) (SK)

This study evaluated the content, concurrent, and construct validity of the Leadership Skills Inventory (LSI), a measure designed to help students analyze the strength of their leadership skills. Results indicated satisfactory content, concurrent, and construct validity, although factor analysis revealed that the LSI contained only one factor, not…

The Philosophies Held by Instructors of Lifelong-learners (PHIL) was developed to identify a respondent's preference for one of the major schools of philosophical thought: Idealism, Realism, Pragmatism, Existentialism, or Reconstructionism. Using the pool of items from an established instrument, its final form and content validity were determined…
