The purpose of this paper is to highlight some psychometric cautions that should be observed when seeking to develop short form versions of tests. Several points are made: (1) score reliability is impacted directly by the characteristics of the sample and testing conditions; (2) sampling error has a direct influence on reliability and factor…

This research study was designed to establish the reliability of the Teenage Nonviolence Test (TNT). The consistency and factor structure of the TNT using a sample of 376 adolescents were evaluated. The stability of the TNT was assessed over time by administering the TNT twice with a two week intervening interval to 87 adolescents. The TNT appears…

It has been shown that the fundamental assumptions associated with conventional one-factor measurement models are frequently violated in analyses of scores from a test composed of testlets. Eight different measurement models were conceptualized for this kind of situation, and the goodness of fit of each model was examined. Measurement models…

Author presents an illustration of a general method of factor matrix analysis, a versatile tool for the comparative study of systems of educational thought, analogous to the comparative methods, using categorical constructs, that are now widely recognized as fundamental in the behavioral sciences.

Since both the means and reliabilities of the ratings were affected by the number of scale levels but not by the manner of defining scale levels, it would appear that the most critical consideration in rating scale construction is that of determining the appropriate number of rating scale levels.

A procedure is outlined showing how the axiom of local independence for latent structure models can be weakened. (CK)

Relations between maximum likelihood factor analysis and factor indeterminacy are discussed. (CK)

Factors were rotated to simple structure by the Kaiser Varimax procedure. Seven factors resulted, accounting for 83.5 percent of the total variance. The factors were defined by SVIB variables which had high loadings and high intercorrelations. Previous groupings into occupational families were challenged. A recommended regrouping of SVIB variables…

Results of a factor analysis of the Conners Teacher Rating Scales for over 9,000 children provided preliminary evidence that hyperactivity and an aggressive conduct disorder can exist independently in children. (RH)

This paper examines the properties of the Item Efficiency Index proposed by Neill and Jackson (1976; EJ 137 077) for minimum redundancy item analysis. (Author/BW)

The concurrent and predictive validity of the Achievement Anxiety Test (AAT) were investigated. The evidence gives cause to be concerned about the quality of a difference score because of the nonindependence of the two scores. Further, the underlying structure of the instrument appears to be more complex than originally hypothesized. (Author/GK)

Examined locus of control scores and factor patterns, using Nowicki-Strickland Locus of Control Scale for Children. Multidimensionality was supported by factor analyses of emotionally disturbed, delinquent, and elementary public school children. Differences in factor patterns raised questions about interpreting inventory scores as reflecting same…
