This paper considers some decisions that must be made by the researcher conducting an exploratory factor analysis. The primary purpose is to aid the researcher in making informed decisions during the factor analysis instead of relying on defaults in statistical programs or traditions of previous researchers. Three decision areas are addressed.…

Three-mode factor analysis (3MFA) and PARAFAC are methods that describe three-way data. A class of 3MFA models is introduced that falls between 3MFA and PARAFAC and contains the good properties of both approaches, including the unique axes property that has distinguished the PARAFAC model. (SLD)

Proposes an index for assessing the degree of factor simplicity in the context of principal components and exploratory factor analysis. The index does not depend on the scale of the factors, and its maximum and minimum are related only to the degree of simplicity in the loading matrix. (SLD)

Proposes a rescaled Bartless-corrected statistic for evaluating the number of factors in exploratory factor analysis with missing data, nonnormal data, and in the presence of outliers. Numerical results illustrate the sensitivity of classical methods and advantages of the proposed procedures. (SLD)

Investigated the conditions under which the matrix of factor loadings from the factor analysis model with equal unique variances will give a good approximation to the matrix of factor loadings from the regular factor analysis model. Extends the results to the image factor analysis model. Discusses implications for practice. (SLD)

Proposes a special rotation procedure for the exploratory dynamic factor model for stationary multivariate time series. The rotation procedure applies separately to each univariate component series of a q-variate latent factor series and transforms such a component, initially represented as white noise, into a univariate moving-average.…

Proposes Promin as an alternative to Promaj for the rotation of oblique factors. Identifies advantages of the Promin approach, which seems to perform better than other well-known procedures. (SLD)

Assessed the extent to which results in exploratory factor analysis (EFA) studies can be replicated by confirmatory factor analysis in the same sample. Used 10 factor structures drawn from the literature. Results show that confirmatory factor models in which all low EFA pattern coefficients were fixed to zero fitted especially poorly. (SLD)

The primary aim of this study was to develop, standardize, and establish initial reliability and validity for the Adolescent Minor Stress Inventory (AMSI), a new measure of minor stress for adolescents. The AMSI improves upon existing adolescent stress measures in a number of important ways in that it does not emphasize school or classroom-based…

This study sought to validate measures of caretaker readiness to facilitate meaningful participation in the Exceptional Student Education (ESE) educational decision-making process. School districts have encountered great difficulty in achieving the federal standards for meaningful participation in educational decision making due to a lack of…

This research study examined how a multinational company determined what the critical success factors (CSFs) were for developing global e-learning. The study analyzed how these CSFs were grouped together in order to make their management more efficient. There were 21 participants in the study who were key stakeholders and came from one of four…

Background: Persistent calls for school-based education about stuttering necessitate a better understanding of peer attitudes toward children who stutter and a means to measure outcomes of such educational interventions. Langevin and Hagler in 2004 developed the Peer Attitudes Toward Children who Stutter scale (PATCS) to address these needs and…

Four studies present the validation of a self-report scale capturing "academic entitlement," which is defined as the tendency to possess an expectation of academic success without a sense of personal responsibility for achieving that success. The Academic Entitlement scale possesses a 2-factor structure (Study 1); 10 items measure students'…

Youth strengths are as important to consider as deficits in understanding developmental outcomes and thus are an important component of psychoeducational assessment. Latino/as are understudied with regard to strength-based constructs, although cultural and socioeconomic factors may be related to differences in Latino/a parents' views of their…

This comprehensive study involved the use of the what is happening in this class? (WIHIC) questionnaire among 2310 Singaporean Grade 10 students (aged 15 years) in 75 geography and mathematics classes in 38 schools. A seven-scale factor structure was strongly supported and the alpha reliability of each scale was high. An investigation of…
