Background: The Restricted, Repetitive Behaviours and Interests (RRBIs) are represented in the DSM-IV and measured by the Autism Diagnostic Interview-Revised (ADI-R) as one of the three homogeneous symptom categories of Pervasive Developmental Disorders. Although this conceptualisation is well accepted in the field, the grouping of symptoms is…

This article reviews the development of a new measure to assess children's perceptions of intergenerational boundary violations in families. The Boundary Violations Scale is a theoretically derived instrument consisting of 12 items. Principal components analysis using data from 119 young adolescents from diverse ethnic backgrounds (i.e., 56%…

The authors compared 2-, 3-, 4-factor, and 2-factor/4-facet Psychopathy Checklist-Revised (PCL-R) models in a previously unpublished sample of 1,566 adult male sex offenders assessed under applied clinical conditions as part of a comprehensive state-mandated community notification risk assessment procedure.

This article describes the development and initial validation of obtained scores from the Academic Expectations Stress Inventory (AESI), which measures expectations as a source of academic stress in middle and high school Asian students. In the first study, exploratory factor analysis results from 721 adolescents suggested a nine-item scale with…

There is disagreement among researchers as to whether creativity is a unidimensional or multidimensional trait. Much of the debate centers around the most widely used measure of creativity, the Torrance Tests of Creative Thinking (TTCT). This study used data from 1,000 kindergartners (ages 5-7), 1,000 third graders (ages 7-11) and 1,000 sixth…

This study investigated factors related to score differences on computerized and paper-and-pencil versions of a series of primary K-3 reading tests. Factors studied included item and student characteristics. The results suggest that the score differences were more related to student than item characteristics. These student characteristics include…

The psychometric properties of the Parenting Stress Index-Short Form (PSI-SF) were examined in a sample of 185 mothers and fathers. Factor analysis revealed 2 reasonably distinct factors involving parental distress and dysfunctional parent-child interactions. Both scales were internally consistent, and these scales were correlated with measures of…

Control beliefs and social relationships have been individually assessed in relation to adaptation to chronic illness, although only rarely together. Further, some control scales show psychometric limitations in older adult samples. To address these concerns, a scale assessing external control was created by factor analyzing the items from…

Despite anecdotal evidence suggesting that air travel is personally demanding, little research has examined air travel stress. To address these issues, the author developed and evaluated the 1st known measure of air travel stress-the Air Travel Stress Scale-in 3 studies. Exploratory and confirmatory factor analysis indicated 3 components: (a)…

This article presents a critical review of complexity theory in relation to educational research. The "analytical reductionist" approach is one in which the educational researcher seeks to reduce complex wholes to particular factors and to identify correlations between them and desirable outcomes. Complexity theory shows how this approach in…

Elementary students (n = 277, in Grades 5-6) and high school students (n = 615, in Grades 7-12) responded to 26 items of McInerneys Facilitating Conditions Questionnaire (FCQ). Confirmatory factor analyses of the FCQ found seven distinct factors underlying these items. These were perceived value of schooling (Value), affect toward schooling…

Linear models of two of the most salient motivations for undergraduates to attend college--learning (intrinsic) and enhanced post-graduation earnings (extrinsic)--are estimated from a sample of 2,199 respondents to the 2000 Cooperative Institutional Research Program (CIRP) survey of first-year students, supplemented by institutional records. Model…

Attracting and retaining highly qualified school leaders is becoming increasingly important in our nation. The purpose of this study was to identify factors that motivate or inhibit practicing teachers from seeking administrative positions.

This study is an analysis of the nature and meaning of bullying in schools. First, the literature on student bullying is reviewed and a definition of bullying is proposed. Next, we developed a set of items to operationalize teacher perceptions of student bullying. An initial, exploratory factor analysis suggested two rather distinct aspects of…

Schutte et al.'s (1998) emotional intelligence scale was adapted and administered to 177 Turkish educators. Confirmatory and exploratory factor analyses were performed. In order to confirm the authors' model and findings of previous research, one, two, three, and four factor models were examined. It was decided that the one factor model fitted the…
