The psychometric adequacy of three sex role instruments was determined by performing a factor analysis on the items in the Bem Sex Role Inventory, the Personal Attributes Questionnaire, and Heilbrun's Masculinity and Feminity Subscales. Subjects were 400 college students who responded to 116 bipolar items from the three instruments. The eleven…

Describes a new approach for analyzing an individual's responses made at multiple times. Proposes that three sources of variance determine a person's current standing on a variable: trait (term does not change), state (term changes), and error (random term). Shows how structural equation modeling can be used and presents an extended example. (RJM)

A multidimensional item response theory (IRT) model for polytomously scored items, based on the graded response model and using the normal ogive, is developed; and an EM algorithm that may be used to estimate the parameters of the model is also discussed. The model is illustrated through a simulation study in which the polytomous item responses of…

Assigned factor scores to therapist and client utterances. Constructed a 17 x 17 correlation matrix consisting of correlations across 4 lagged utterances. Principal-components analysis revealed 4 therapist-client interaction factors: mutual therapeutic engagement, mutual therapeutic negotiation, undirected client reminiscence, and sustained…

Limitations of the confirmatory factor analysis conducted by H. W. Marsh to demonstrate the multidimensionality of a rating form to assess student evaluation of teaching effectiveness are discussed. A secondary analysis suggests that dimensionality is not stable across solutions and a global factor can be retrieved. (SLD)

The purposes of the present investigation are to evaluate a new, adaptive procedure for assessing multiple dimensions of self-concept for children younger than 8 years and to examine related theoretical issues. The multidimensional, hierarchical structure of self-concept is well established for older children, but there is a paucity of research…

The sources of multidimensionality found in several different forms of a licensure examination were studied. The relationship between one source of multidimensionality, differential item functioning (DIF) (or factors producing DIF), and content characteristics was explored in an attempt to isolate aspects of training or curriculum that could…

The Multidimensional Test of Self-Concept (MTS) is based on the assumption that an individual's perception of his/her well-being is related to the difference between the current state of that individual and the desired state. This difference between the two states may be directly measured, and a single self-concept score generated. The MTS…

Describes a new 48-item self-report instrument, the Multidimensional Measure of Children's Perceptions of Control, which defines children's perceptions of control as understanding the locus of sufficient cause for success and failure. Three dimensions of third- through ninth-grade children's perceptions of control are assessed within three…

Confirmatory factor analysis of responses by 211 preadolescents (M age = 10.25 years,SD = 1.48) with mild intellectual disabilities (MIDs) to the individually administered Self Description Questionnaire I-Individual Administration (SDQI-IA) counters widely cited claims that these children cannot differentiate multiple self-concept factors. Results…

A new adaptive procedure for assessing multiple dimensions of self-concept for children younger than 8 years was studied with a sample of 501 children from kindergarten through grade 2. Use of the Self-Description Questionnaire with young children was supported by factor analysis. Practical and theoretical implications are discussed. (SLD)
