Original formulations of the Work Locus of Control Scale (WLCS) proposed a unidimensional structure of this measure; however, more recently, evidence for a two-dimensional structure has been reported, with separate subscales for internal and external loci of control. The current study evaluates the one- and two-factor models with confirmatory…

Math anxiety levels and performance outcomes were compared for bilingual and monolingual community college Intermediate Algebra students attending a culturally diverse urban commuter college. Participants (N = 618, 250 men, 368 women; 361 monolingual, 257 bilingual) completed the Abbreviated Math Anxiety Scale (AMAS) and a demographics instrument.…

Psychometric properties are described for an inventory that measures the daily rewards and worries that parents experience as their sons and daughters transition to adulthood. In a series of 4 studies involving 847 respondents, we explored and confirmed the factor structure of the Transition Daily Rewards and Worries Questionnaire (TDRWQ) in a…

This study presents the development of a new instrument, the "Multidimensional Attitudes Scale Toward Persons With Disabilities" (MAS). Based on the multidimensional approach, it posits that attitudes are composed of three dimensions: affect, cognition, and behavior. The scale was distributed to a sample of 132 people along with a…

The present paper examined the underlying structure of Dutch adolescents' peer crowd identification and its relations with delinquency, aggression, depression, and anxiety. Questionnaire data were gathered from 2,334 adolescents between ages 12 and 19. Exploratory and confirmatory factor analyses revealed four clearly interpretable…

Background: Attitudes to the sexual expression of adults with an intellectual disability (ID) are one reflection of the inclusiveness of a community. Our capacity to measure attitudes towards this important aspect of adult life is limited by the lack of an appropriate instrument. The aim of this study was to continue the development of a recently…

To examine Swanson, Nolan, and Pelham-IV (SNAP-IV) psychometric properties, parent (N = 1,613) and teacher (N = 1,205) data were collected from a random elementary school student sample in a longitudinal attention deficit hyperactivity disorder (ADHD) detection study. SNAP-IV reliability was acceptable. Factor structure indicated two ADHD factors…

Background: The behavioural and academic performance of young children with teachers' reported hyperactivity, conduct problems or inattention is under debate. Aim: This study investigates the associations between teachers' reported behavioural difficulties and academic and cognitive performances in two large samples of preschool and school…

Building upon earlier confirmatory factor analytic research that validated a second-order, three-factor structure of the Beck Depression Inventory for Canadian and Swedish nonclinical adolescents, this study tested the factorial structure of the Swedish version of the instrument separately for 559 males and 537 females, and tested its measurement…

Some years ago, B. Efron and his colleagues developed bootstrap resampling methods as a way of estimating the degree to which statistical results will replicate across variations in sample. A basic problem in the multivariate use of bootstrap procedures involves the requirement that the results across resamplings must be rotated to best fit in a…

In previous research, no relationship was found between test factor structure and test hierarchical structure. This study found some correspondence between test factor structure and test inter-item dependency structure, as measured by a log-linear model. There was an inconsistency, however, which warrants further study: more significant two-item…

A study examined the extent to which a 19-item short form of the Speech Evaluation Instrument (SEI) is a reliable instrument, what factor structure emerges from the analysis, and how that factor structure compares to that reported for the 30-item long form of the SEI. Subjects, 606 undergraduates enrolled in speech communications classes at two…

Through a review of the literature, this paper explores the viability of the rotation of canonical correlation analysis results. The similarities and dissimilarities between factor analysis and canonical correlation analysis are examined. The logic supporting a preference for the rotation of structure coefficients as opposed to function…

While scales assessing psychological well-being have been used both as criterion measures and as variables of interest in their own right, there has been little attempt to deal with the issue of the time-boundedness of perceived well-being. A study was undertaken to examine the combined factor structure of two measures of well-being, the…

Theory and common sense posit that the effect of a specific facet of self-concept on Global Esteem will vary with the importance placed on that facet, but no support for this interactive hypothesis was found. Unweighted averages of 12 distinct dimensions of self-concept from the Self Description Questionnaire III correlated about .7 with Global…
