The aim of this study is to develop a valid and reliable instrument to assess why physics courses are perceived as one of the most difficult courses among high school students and to investigate the reasons why students have difficulty in learning physics through this scale. This study includes the development and validation studies of the…

Direct linkEisenberg, Nancy; Edwards, Alison; Spinrad, Tracy L.; Sallquist, Julie; Eggum, Natalie D.; Reiser, Mark – Developmental Psychology, 2013
The primary goal of this study was to examine whether effortful control (EC; effortful regulation), reactive undercontrol (IMP; e.g., impulsivity, speed of approach), and reactive overcontrol (NOV; inhibition to novelty) were 3 distinct constructs at 30 months (Time 1; n = 216), 42 months (Time 2; n = 192), and 54 months (Time 3; n = 168) of age.…

Norris, Megan; Lecavalier, Luc; Edwards, Michael C. – Journal of Autism and Developmental Disorders, 2012
The current study tested several competing models of the autism phenotype using data from modules 1 and 3 of the ADOS. Participants included individuals with ASDs aged 3-18 years (N = 1,409) from the AGRE database. Confirmatory factor analyses were performed on total samples and subsamples based on age and level of functioning. Three primary…

Niclasen, Janni; Skovgaard, Anne Mette; Andersen, Anne-Marie Nybo; Somhovd, Mikael Julius; Obel, Carsten – Journal of Abnormal Child Psychology, 2013
The aim of this study was to examine the factor structure of the Strengths and Difficulties Questionnaire (SDQ) using a Structural Confirmatory Factor Analytic approach. The Danish translation of the SDQ was distributed to 71,840 parents and teachers of 5-7 and 10-12-year-old boys and girls from four large scale cohorts. Three theoretical models…

Objective: To examine the factor structure of attention-deficit/hyperactivity disorder (ADHD) in a clinical sample of 1,373 children and adolescents with ADHD and their 1,772 unselected siblings recruited from different countries across a large age range. Hierarchical and correlated factor analytic models were compared separately in the ADHD and…

Denham, Susanne A.; Warren-Khot, Heather K.; Bassett, Hideko Hamada; Wyatt, Todd; Perna, Alyssa – Journal of Experimental Child Psychology, 2012
The importance of early self-regulatory skill has seen increased focus in the applied research literature given the implications of these skills for early school success. A three-factor latent structure of self-regulation consisting of compliance, cool executive control, and hot executive control was tested against alternative models and retained…

Plenty, Stephanie; Heubeck, Bernd G. – Educational Research and Evaluation, 2011
Most traditional models of academic motivation focus on a small number of specific factors. However, the Student Motivation and Engagement Scale (MES) (Martin, 2007b) includes a fairly comprehensive range of perspectives on general student motivation. The current study set out (a) to provide an independent test of the proposed 11-factor structure…

Akyol, Zehra; Ice, Phil; Garrison, Randy; Mitchell, Rob – Internet and Higher Education, 2010
The Community of Inquiry Framework is based on the premise that online learning is a collaborative constructivist activity. However, not all courses are similarly oriented. In general, courses can be divided into constructivist and objectivist. In constructivist courses, learners develop solutions to problems through sustained discourse and…

The psychometric properties and factor structure of the Dysfunctional Attitudes Scale were examined in a sample of 422 male and female adolescents (ages 12-17) with current major depressive disorder. The scale demonstrated high internal consistency ([alpha] = 0.93) and correlated significantly with self-report and interview-based measures of…

MacArthur, Charles A.; Konold, Timothy R.; Glutting, Joseph J.; Alamprese, Judith A. – Journal of Learning Disabilities, 2010
The purposes of this study were to investigate the reliability and construct validity of measures of reading component skills with a sample of adult basic education (ABE) learners, including both native and nonnative English speakers, and to describe the performance of those learners on the measures. Investigation of measures of reading components…

Bowden, Stephen C.; Weiss, Lawrence G.; Holdnack, James A.; Lloyd, Delyth – Psychological Assessment, 2006
Examination of measurement invariance tests the assumption that the model underlying a set of test scores is directly comparable across groups. The observation of measurement invariance provides fundamental evidence for the inference that scores on a test afford equivalent measurement of the same psychological traits among diverse groups. Groups…

Peer reviewedHorn, John L. – Intelligence, 1980
This article summarizes results from studies of the organization and development of cognitive abilities in adults aged 20 to 60 years old. Theories of intelligence stipulating a hierarchy of intellectual functions, with fluid and crystallized intelligence at the top, are supported. Six conclusions on age differences are offered.

Over 600 White females between 10.5 and 18.5 years of age were studied to test construct comparability across adolescence. Assessed were emotional functioning, eating problems, self-reflection, self-image, and mastery/adjustment to examine meaning equivalence in self-concepts and developmental psychopathology. Results suggest that the five factors…

Confirmatory factor analysis was used to test 3 models of the Wechsler Intelligence Scale for Children-III (2-, 3-, and 4-factor conceptualizations) for 11 age groups with 200 subjects per age group. The four-factor model is somewhat supported, but its theoretical or clinical importance is unclear. (SLD)

Studied structure of Stanford-Binet: Fourth Edition for normal children who were not part of standardization sample. Found that, for children aged 2-6 years, either 2- or 3-factor model could be supported. For students aged 7-11, neither of 2 models studied was supported. Alternative model with verbal reasoning, quantitative reasoning,…
