This article outlines a readily and widely applicable procedure of reliability evaluation for scales with unidimensional measures. The method is developed within the framework of the popular latent variable modeling methodology, and it accomplishes point, as well as interval, estimation of measuring instrument reliability. The approach can be…

Two studies were conducted to examine validity evidence for the College Self-Efficacy Inventory, by investigating dimensionality and theoretically based relationships with external criteria. Modifications to the scale yielded an adequately fitting three-factor model, and most hypothesized relationships were empirically supported. However,…

The Posttraumatic Growth Inventory (PTGI; R. G. Tedeschi & L. G. Calhoun, 1996) was used to measure the growth of university students (N = 347). Results were compared with those of trauma studies and indicate that the PTGI is a general measure of growth suitable for future nontrauma studies. Results reflect a minimal relationship between…

Vocational psychology has generated a number of concepts and assessment instruments considered to reflect ability self-concept (i.e., one's view of one's own abilities) relevant to career development. These concepts and measures often are categorized as either self efficacy beliefs or self-estimated (i.e., self-rated, self-evaluated) abilities.…

Underlying pro- and anti-Black components accounted for significant variance in various racial scale scores among African Americans (N = 224). Intercorrelations for individual racial scale scores were consistent with theory and accounted for significant variance in psychological distress scores in patterns consistent with their representation of a…

Examines the reliability and validity of the scores of the Assessment of Academic Self-Concept and Motivation Scale (AASCM), a new instrument developed according to motivational systems theory. The AASCM was administered to African American, European American, and Hispanic participants (N=492). Presents evidence of the measurement's strong…

The authors examined the extent to which the Realistic, Investigative, Artistic, Social, Enterprising, and Conventional scales and 3-point codes of the Self-Directed Search may be considered statistically and practically equivalent across 3 different modes of administration: paper-and-pencil, personal computer, and Internet. Student preferences…

The authors describe use and development of the University of Rhode Island Change Assessment (E. I. McConnaughy, J. O. Prochaska, & W. F. Velicer, 1983) and examine the psychometric properties of scores from incarcerated male adolescents. Cluster analysis revealed 3 unique profiles (Precontemplators, Participators, and Undifferentiated).…

Accurate screening of disruptive behavior disorders such as attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder are a priority in elementary schools and child guidance clinics but they can be challenging because of symptom overlap with other disorders. The use of behavioral rating scales for assessing children's…
