There is growing concern over graduating trainee teachers' insufficient level of Information and Communication Technology (ICT) literacy. The main purpose of this research was to describe the nature of trainee teachers' ICT literacy at the beginning of preservice training: (a) to explore the structure and to identify the main components of…

College drinking behavior is a national public health concern. However, little research has been conducted to test the psychometric validity and reliability of alcohol use measures among Spanish-speaking Hispanic college students. Adopting a translation-back-translation approach, the Rutgers Alcohol Problem Index (RAPI) was translated into Spanish…

The purpose of this investigation was to test the age-related measurement invariance and temporal stability of the 13-item version of Antonovsky's Sense of Coherence Scale (SOC). Multigroup structural equation modeling of longitudinal data from the Canadian National Population Health Survey was used to examine the measurement invariance across 3…

This paper presents findings of a study that developed, measured, and tested the Organizational/Supervisory (O/S) Model of Instructional Supervision. The six dimensions of the Organizational Supervisory Climate Inventory (OSCI)--organizational structure, professional autonomy, collaborative sharing, district supervisory climate, reflection, and…

A mental model is a knowledge structure composed of concepts and the relations between them. Mental models are distinct from declarative and procedural knowledge--they go beyond semantic relationships and skills acquisition and contain varied intellectual skills and knowledge. This study describes an initial investigation into the construct…

The first study described in this paper estimates the reliability of the four subscale versions of the 40-item Computer Attitude Scale (CAS), an instrument designed to measure attitudes toward learning about and using computers. It provides detailed information about the factor patterns of CAS subscales and evidence of the differential validity of…

A study investigated whether some level of writing apprehension or some expressed attitude toward writing might result in better essay scores. Subjects, 255 freshmen composition students at two campuses of the California State University system, were administered instruments designed to comparatively measure the quality of students' writing, gauge…

This paper presents abstracts of 80 individual papers and panel discussions that deal with journalism, popular culture, mass media, "science" in public discourse, the social construction of communication technologies, factorial analysis as a research tool, and other issues in communication. Almost all of the abstracts in the paper are…

This paper presents a methodology for developing a framework that can help decision makers distinguish intensity of needs and regional funding differences within a state. A cluster analysis was used to distinguish need in Georgia's 159 counties. Four clusters that identified the distribution of goods or services to those in need were identified:…

This report documents the construct validity and reliability of the Professional Development Inventory (PDI), an assessment center sponsored by the National Association of Elementary School Principals (NAESP). The assessment center provides a means for assessing participants in situations simulating those confronted by principals on the job. The…

This study sought to determine whether the dimensions underlying a comprehensive set of 15 work-relevant abilities were similar to the Data/Ideas and Things/People Work Task Dimensions (D. J. Prediger, 1996) underlying J. L. Holland's (1997) hexagonal model of interest and occupational types. The work task dimensions and a general ability…

A large government agency had been experiencing a variety of changes. The new head of the agency approached communication researchers about doing analyses of the effectiveness of communication in the agency. The researchers conducted two studies: a qualitative one to identify organizational and organizational communication themes, and a…

Early intervention has shifted in focus to family centered assessment and treatment. The Comprehensive Evaluation of Family Functioning was developed to meet the need for accurate family assessment, but limited psychometric information on the measure is available. The present research investigated the psychometric properties of the CEFF with a…

Two analyses of variance (ANOVA) models for item scores are compared. The first is an items by subject random effect ANOVA. The second is a mixed effects ANOVA with items fixed and subjects random. Comparisons regarding reliability, Cronbach's alpha coefficient, psychometric inference, and inter-item covariance structure are made between the…

Selected methods for evaluating the stability of research results empirically are described, especially with regard to multivariate analysis. It is critically important to evaluate the influences of sampling error on obtained results; statistical significance testing does not inform judgment regarding the probable replicability or the sampling…
