Direct linkSalter, Daniel W.; Junco, Reynol – Educational and Psychological Measurement, 2007
This concurrent validity study of Salter Environmental Type Assessment scores was conducted with the Group Environment Scale. A principal components factor analysis with varimax rotation of 191 college students' responses suggested two factors that accounted for 51% of the variance. The factor-analytic results and concurrent validity coefficients…

Gibbons, Robert D.; Bock, R. Darrell; Hedeker, Donald; Weiss, David J.; Segawa, Eisuke; Bhaumik, Dulal K.; Kupfer, David J.; Frank, Ellen; Grochocinski, Victoria J.; Stover, Angela – Applied Psychological Measurement, 2007
A plausible factorial structure for many types of psychological and educational tests exhibits a general factor and one or more group or method factors. This structure can be represented by a bifactor model. The bifactor structure results from the constraint that each item has a nonzero loading on the primary dimension and, at most, one of the…

Brinkley, Jason; Nations, Laura; Abramson, Ruth K.; Hall, Alicia; Wright, Harry H.; Gabriels, Robin; Gilbert, John R.; Pericak-Vance, Margaret A. O.; Cuccaro, Michael L. – Journal of Autism and Developmental Disorders, 2007
Exploratory factor analysis (varimax and promax rotations) of the aberrant behavior checklist-community version (ABC) in 275 individuals with Autism spectrum disorder (ASD) identified four- and five-factor solutions which accounted for greater than 70% of the variance. Confirmatory factor analysis (Lisrel 8.7) revealed indices of moderate fit for…

This study compared teachers' ratings of behavioral and emotional problems on the Teacher's Report Form for general population samples in 21 countries (N = 30,957). Correlations between internal consistency coefficients in different countries averaged 0.90. Effects of country on scale scores ranged from 3% to 13%. Gender effects ranged from less…

Constraints Affecting ICT Utilization by Agricultural Extension Officers in the Niger Delta, Nigeria
Akpabio, I. A.; Okon, D. P.; Inyang, E. B. – Journal of Agricultural Education and Extension, 2007
The study focused on constraints affecting the utilization of Information and Communication Technologies (ICT) for agricultural extension activities by Agricultural Extension Officers in Nigeria's Niger Delta Region. Data were derived from 160 extension officers affiliated to both public and private extension organizations in four states of the…

Suldo, Shannon M.; Shaffer, Emily J. – Journal of Psychoeducational Assessment, 2007
Two studies addressed the psychometric properties of the Self-Efficacy Questionnaire for Children (SEQ-C) when used in studies with American youths. A sample of 697 middle and high school students completed the SEQ-C along with measures of life satisfaction and psychopathology. Exploratory factor analysis procedures supported the existence of…

Bernstein, Amit; Zvolensky, Michael J.; Stewart, Sherry; Comeau, Nancy – Behavior Therapy, 2007
This study represents an effort to better understand the latent structure of anxiety sensitivity (AS), a well-established affect-sensitivity individual difference factor, among youth by employing taxometric and factor analytic approaches in an integrative manner. Taxometric analyses indicated that AS, as indexed by the Child Anxiety Sensitivity…

Bridgstock, Ruth – Australian Journal of Career Development, 2007
This paper documents the initial development and validation of a brief quantitative measure of career development influences based on the Systems Theory Framework (STF) of career development (McMahon & Patton, 1995; Patton & McMahon, 1997, 1999, 2006). Initial exploratory factor analyses of pilot study data revealed a six-factor structure based on…

Ferrando, Pere J. – Multivariate Behavioral Research, 2007
This paper proposes procedures for assessing the fit of a psychometric model at the level of the individual respondent. The procedures are intended for personality measures made up of Likert-type items, which, in applied research, are usually analyzed by means of factor analysis. Two scalability indices are proposed, which can be considered as…

Choi, Namok; Fuqua, Dale R.; Newman, Jody L. – Educational and Psychological Measurement, 2007
This study examines the structural validity of scores from the Bem Sex Role Inventory using a maximum likelihood confirmatory factor analysis (CFA). Six hundred and sixty-five graduate and undergraduate students participate in the study. A seven first-order factor model almost identical to the model reported in a previous CFA study is used as the…

Sumarto, Sudarno; Suryadarma, Daniel; Suryahadi, Asep – Social Indicators Research, 2007
Household consumption expenditure data is crucial for calculating important welfare measures such as poverty headcount rate. However, collecting such data is difficult and cumbersome. As an alternative, we experiment with three methods--consumption correlates model, poverty probability model, and wealth index principal components analysis…

Vloedgraven, Judith M. T.; Verhoeven, Ludo – Annals of Dyslexia, 2007
The purpose of the present study was to explore the possibilities for the assessment of growth in phonological awareness of children in kindergarten and first grade. Phonological awareness was measured using four sets of items involving rhyming, phoneme identification, phoneme blending, and phoneme segmentation. The results of an exploratory…

Peer reviewedJackson, Douglas N.; Skinner, Harvey A. – Educational and Psychological Measurement, 1975
Univocal varimax is an orthogonal factor rotation strategy aimed at improving upon the simple structure qualities of a preliminary varimax solution. This is accomplished by targetting for patterned rotation the highest element in each row of the varimax factor loading matrix. (Author)

It is shown that common factors are not subject to indeterminancy to the extent that has been claimed (Guttman, 1955), because the measure of indeterminancy that has been adopted is ill-founded. (Author/RC)

Wendler, Cathy L. W. – 1984
The existence of a general construct of self-concept has been well documented and generally accepted. To examine the multidimensionality of self-concept, 485 school age children (248 females, 237 males) completed the Piers-Harris Children's Self-Concept Scale, which included an assessment of six subareas: behavior, intellectual and school status,…
