Historically, most researchers conducting factor analysis have used exploratory methods. However, more recently, confirmatory factor analytic methods have been developed that can directly test theory either during factor rotation using "best fit" rotation methods or during factor extraction, as with the LISREL computer programs developed…

The study attempted to demonstrate significant relationships between systematically derived occupational descriptors and selected measures of worker characteristics in the affective domain. The predictor variables were derived from the Occupation Analysis Inventory (OAI) and consisted of work-dimension scores describing occupations in terms of…

Statistical analyses supported two conclusions: (a) The Physiological and Emotional Security subscales of the HSS are highly saturated with psychopathological symptomatology; and (b) the remaining five HSS subscales measure dimensions of clients' psychosocial and vocational adjustment that are relatively independent of psychopathology.

Male school children (N=241), all aged 16 years, and 144 men facing redundancy completed the 60 item version of the General Health Qestionnaire. Data were analysed using unrotated first principal component analysis followed by oblique rotation. The unrotated first principal component accounted for much of the variance, particularly in the school…

Examines how participation in decision making affects acceptance of planned change. Hypothesizes that participation influences tactical decisions whereas direction affects strategic decisions. Reports that 222 Israeli managers, completing a battery of psychological ability tests, were given the choice to change test type. Concludes that decision…

This review employs a conceptual framework that distinguishes methods of detecting measurement bias based on either observed or unobserved conditional invariance models. The primary interest is in group-level measurement bias. Methods for bias detection in both continuous and ordered-categorical measures are reviewed, as are methods for testlets…

An attempt is made to indicate why the concept of "true score" naturally leads to the belief that test validity must increase with an increase in test and/or average item reliability, and why this is correct for the classical single-factor model first introduced by Spearman. The statistical model used by Loevinger is introduced to…

We concern ourselves with the hypothesis that two variables have a perfect disattenuated correlation, hence measure the same trait except for errors of measurement. This hypothesis is equivalent to saying, within the adopted model, that true scores of two psychological tests satisfy a linear relation. Statistical tests of this hypothesis are…

This study utilized a Latin Squares design to assess equivalence of computer and paper-and-pencil testing methods in a clinical setting with college students. No significant differences between scores on measures of anxiety, depression, and psychological reactance were found across group and administration format. Most subjects preferred…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). This report examines measures of attitude, self-concept, and anxiety as outcomes of mathematics instruction for students in grades 4-12. (NLSMA Reports Nos. 1-7 and 9 provide background information on the measures and the population.) Specific…

The previous theoretical development of the Poisson process as a strong model for the true-score theory of mental tests is discussed, and additional theoretical properties of the model from the standpoint of individual examinees are developed. The paper introduces the Erlang process as a family of test theory models and shows in the context of…

The relationship between student counselors' level of confrontation and personality variables, as measured by the California Psychological Inventory (CPI), was studied. The subjects were 20 graduate students enrolled in two sections of a Counseling Practicum class. Level of confrontation was measured from audio-tape ratings made by the student…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). It is an analysis of a follow-up survey conducted on the Z-Population (students in grades 10-12) approximately one year after the students completed grade 12. (NLSMA Reports Nos. 3, 6, 7, and 9 contain background information on the…

Purpose: In 2 experiments, the assumption that continual orienting to tinnitus uses cognitive resources was investigated. It was hypothesized that differences in performance of tinnitus and control groups would manifest during demanding or unfamiliar tasks that required strategic, controlled processing and that reduced performance was not related…
