Factor analysis of the Bell Reality Testing Inventory items produced three subscales interpreted as dimensions of the reality testing ego function: Reality Distortion, Uncertainty of Perception, Hallucinations and Delusions. Replication factor analysis confirmed the factor structure. Subscales appear sensitive to variations in psychopathology and…

Factor adequacy and other results based on data from college students (N=359) provided positive evidence regarding the construct validity of the Myers-Briggs Type Indicator (MBTI). Second order factor analysis supported the appropriateness of the MBTI item weighting procedures. (Author/ABB)

Investigated the factor structure of the Levels of Attribution and Change (LAC) Scale on two samples: adult smokers (N=194) and professional psycho-therapists (N=140). Analysis of data substantiated the utility and internal validity of the LAC theoretical scales and supported the present scoring system. (LLL)

This study compared the effectiveness of 10 methods of determining the number of factors to retain in exploratory common factor analysis. The 10 methods included the Kaiser rule and a modified Kaiser criterion, 3 variations of parallel analysis, 4 regression-based variations of the scree procedure, and the minimum average partial procedure. The…

A shortcut formula for the computation of "coefficients of invariance" in the comparison of factor structures is presented. A limitation of the coefficient of invariance is pointed out in the case of comparing two first principal components. (NE)

Ratings on a fear inventory for children revealed three dimensions: fear of physical injury, natural events, and psychic stress. A comparison with studies of adult fears suggested that fear of physical injury and psychic stress carry through much of the life span, while fear of natural events mitigates with maturation.

A counterexample is produced to a conjecture by K. G. Joreskog concerning sufficiency conditions for uniqueness of a restricted factor matrix. A substitute condition is stated and proved for the most common situation where the restricted elements are specified to be zero. (Author)

Compared factor structures of the WISC and the WISC-R using the data for age groups 7.5, 10.5, and 13.5 years in the two standardization samples. Results demonstrated that the structures of the two scales are as similar as the structure of either scale is for different age groups. (Author)

Kaiser and Michael reported a formula for factor scores giving an internal consistency reliability and its square root, the domain validity. Using this formula is inappropriate if variables are included which have trival weights rather than salient weights for the factor for which the score is being computed. (Author/RL)

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)

This research reports the development and psychometric properties of scores from the 10-item Short Index of Self-Directedness (SISD), drawn from the Temperament and Character Inventory (TCI; C. R. Cloninger, 1987/1992a) and the TCI-125 (C. R. Cloninger, 1992b). Factor structure, construct validity, internal consistency, and test-retest reliability…
