H. Kaiser (1992) has shown that the sum of coefficients alpha of a set of principal components does not change when the components are transformed by an orthogonal rotation. In this paper, the rotational invariance and the successive alpha-optimality are integrated and generalized in a simultaneous approach. (SLD)

Identifies a general algorithm for orthogonal rotation and shows that when an algorithm parameter alpha is sufficiently large, the algorithm converges monotonically to a stationary point of the rotation criterion from any starting value. Introduces a modification that does not require a large alpha and discusses the use of this modification as a…

An iterative process is proposed for obtaining an orthogonal simple structure solution. At each iteration, a target matrix is constructed such that the relative contributions of the target majorize the original ones, factor by factor. The convergence of the procedure is proven, and the algorithm is illustrated. (SLD)

Used simulated data to test the integrity of orthogonal factor solutions when varying sample size, factor pattern/structure coefficient magnitude, method of extraction, number of variables, number of factors, and degree of overextraction. Discusses implications of results with regard to overextraction. (SLD)

Tucker's method of oblique congruence rotation is shown to be equivalent to a procedure by Meredith. This implies that Monte Carlo studies on congruence by Nesselroade, Baltes, and Labouvie and by Korth and Tucker are highly comparable. The problem of rotating two matrices orthogonally to maximal congruence is considered. (Author/CTM)

A Monte Carlo simulation evaluated conditions that contribute to excessively high coefficients of congruence when fitting one factor pattern matrix into the space of a targeted pattern. Results support the conclusion that orthogonal Procrustes methods of factor rotation do produce spurious coefficients between predictor and criterion factor…

The factor structure of the Kaufman Assessment Battery for Children was evaluated with 169 gifted students, aged 6-10. Results tentatively suggested that the factor solution for gifted students is dissimilar to that for the standardization sample, as subtests designed to assess sequential processing did not all load together, nor did those…

The effects of under and overrotation on common factor loading stability under three levels of common variance and three levels or error are examined. Four representative factor matrices were selected. Results suggested that matrices which account for large amounts of common variance tend to have stable factor loadings. (Author/RL)

The Brand Emotions Scale for Writers (BESW) is a 20-item scale designed to measure writers' emotions immediately before, during, and immediately after writing. This article describes the development of the BESW and the factor structure of the three different scale forms. (BS)

Procedures for assessing the invariance of factors across data sets often use the least squares criterion, which appears to be too restrictive. Tucker's coefficient of congruence is proposed as an alternative. A method that maximizes the sum of the coefficients of congruence between two matrices of loadings is presented. (Author/JKS)

The 72-item Erikson Psychosocial Stage Inventory (EPSI) was factor analyzed for a group of 534 university freshmen and sophomore students. Seven factors emerged, which were labeled Initiative, Industry, Identity, Friendship, Dating, Goal Clarity, and Self-Confidence. Item's representing Erikson's factors, Trust and Autonomy, were dispersed across…

The Piers-Harris Children's Self-Concept Scale was administered twice to a sample of elementary school pupils and both sets of data were factor analyzed. Results led the authors to question the factor stability of the instrument. (Items are included). (JKS)

Analyses of interscale relations in 235 college students for the Vocational Preference Inventory and Vocational Interest Inventory, based on interest models of Holland and Roe, respectively, suggest that the two-dimensional, circular configuration of occupational or personality types may be an oversimplification which impedes the understanding of…

The standardization sample of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) was the basis for an analysis of the WAIS-R subscales in relation to demographic variables. Canonical correlation with orthogonal rotation of composite structural components was performed in order to determine interrelations between both sets of variables.…

A Wherry-Wherry hierarchical factor solution was obtained on the Wechsler Adult Intelligence Scale (WAIS) subtest performance of 100 adolescent retardates. The hierarchical arrangement of abilities obtained was consistent with Vernon's model of cognitive structure and previous reports. A g-factor and two major group factors were evident.…
