A modification of the TUCKALS3 algorithm is proposed that handles three-way arrays of order I x J x K for any I. The reduced work space needed for storing data and increased execution speed make the modified algorithm very suitable for use on personal computers. (SLD)

Research on the direct-product model is extended by deriving hierarchically nested models for explicitly testing the patterns of method and trait factors and through formal tests developed for the pattern of communalities. These procedures are illustrated, and use of the MUTMUM computer program is discussed. (SLD)

A generalization of the single trait, multioccasion measurement model is provided through a confirmatory measurement model for multitrait-multioccasion (MTMO) data. Several commonly used confirmatory measurement models are contrasted with the MTMO, and it is illustrated with a large four-wave dataset on family support and alcohol involvement. (SLD)

The evaluation of an intervention delivered across multiple treatment sites presents a unique opportunity for evaluators to gauge the manner and degree to which the "impact" of treatment varies across implementation conditions and different target populations. However, the availability of implementation data for each treatment site, while…

Primary health care nurses are frequently overlooked when delivering services to children with developmental disabilities, despite the fact that they are often the first contact many primary caregivers have with rehabilitation professionals and usually remain the bridge between caregivers and professionals. A time series one group design with…

This paper reports on a commissioned research project to evaluate the impact of support (mainly funding) given by the UK Government's National Endowment for Science, Technology and the Arts (NESTA) to various projects under the general heading of "science learning" over a four-year period (2000-2004). Findings emerging from the study…

The present study investigated the factor structure of a field trial sample of the Test of English as a Foreign Language™ Internet-based test (TOEFL® iBT). An item-level confirmatory factor analysis (CFA) was conducted for a polychoric correlation matrix of items on a test form completed by 2,720 participants in the 2003-2004 TOEFL iBT Field…

This study investigates the latent structure of individual differences in vocational, leisure, and family interests. The participants consisted of 302 French adults who rated their like or dislike for activities based on Holland's RIASEC typology and presented in three life domains: work, family and leisure. The multitrait-multimethod model…

In this article we examine empirical evidence on the criterion, predictive, transfer, and fairness aspects of validity of a large-scale language arts performance assessment, referred to as the Performance Assignment (PA). We use multilevel models to avoid biased inferences that might result from the naturally nested data. Specifically, we examine…

The Life-Patterns project is a panel-cohort longitudinal study following the life trajectories of 1,908 young people who left school in Victoria in 1991. The project attempts to obtain nuanced pictures of young people's lives in three ways: using a reflexive longitudinal study design, with opportunities for participant feedback and influence on…

Leadership depends on the situation. Few social scientists would dispute the validity of this statement. But the statement can be interpreted in many different ways, depending, at least in part, on what one means by leadership. This article begins with a definition of leadership and a brief description of 3 historically important theories of…

Cognitive engagement in self-regulated learning was investigated at the levels of component cognitive processes and sets of these components (acquisition and transformation) by collecting data on the cognition of 33 high school seniors. Multitrait-multimethod analyses reveal that measures of self-regulated learning are not coherent. (SLD)

The Leadership Attitudes and Beliefs Scale was studied in 65 males and 111 females between 19 and 22 years old. Results supported the convergent and discriminantive validity of the Systemic Thinking scale and the divergent and discriminantive validity of the Hierarchical Thinking scale. (Contains 61 references and 2 tables.) (GCP)

This paper describes the validation of actual and preferred forms of a new classroom environment instrument--the Technology-Rich Outcomes-Focused Learning Environment Inventory (TROFLEI)--using multitrait-multimethod modelling. The 80-item TROFLEI assesses 10 classroom environment dimensions: Student Cohesiveness, Teacher Support, Involvement,…

This study examined the relationship between children's sports participation and emotional well-being including self-reported emotional and behavioral problems and multidimensional aspects of self-concept. Data were collected from 203 young adolescents using a multitrait-multimethod assessment methodology. Information was obtained using a sports…
