The lack of a conceptually and psychometrically strong measure of human mental workload has undermined interpretations of research based on cognitive load theory. Applying a confirmatory factor analysis approach to construct validation, a Subjective Mental Workload Survey was developed with four distinct subscales: Difficulty, Incompetence,…

Confirmatory factor analysis was used to examine the construct validity of scores from the Survey of Perceived Organizational Support (SPOS)(R. Eisenberger and others, 1986) using responses of 205 college faculty and staff members. Consistent with previous research, the SPOS was found to be unidimensional and distinguishable from two similarly…

Analyzes whether the latest version of the Wechsler Intelligence Scale for Children (WISC-III) measures the same constructs across its 11 age spans and what constructs are measured by the WISC-III. Findings indicate that WISC-III does measure the same constructs across ages but does not measure Freedom from Distractibility. (RJM)

Two samples (251 undergraduates and 1,788 employed adults) completed the Career Beliefs Inventory. Confirmatory and exploratory factor analyses did not support the conclusion that scale scores cluster in an expected manner for either the five-factor or the four-factor model. (SK)

Confirmatory factor analysis was used to evaluate the factor structure of the eight cross-informant scales of the Child Behavior Checklist (T. M. Aschenbach, 1991) using data from 631 youth ages 8 to 18. Results support Aschenbach's eight- correlated-factor model and the construct validity of the measure's scores. (SLD)

Three instruments were completed by 345 undergraduates: Kuder Task Self-Efficacy Scale (KTSES), Self-Esteem Inventory, and Career Decision-Making Self-Efficacy Scale. The construct validity of the KTSES was supported, and some relationship was found between career task self-efficacy and self-esteem/career decision-making self-efficacy. (SK)

Three groups of subject-matter experts reviewed the content validity of the Newcomer Socialization Questionnaire. Its psychometric properties were supported in a study of 492 employed students; the study was replicated with 320 newly hired workers. Socialization dimensions were positively correlated with job satisfaction and organizational…

A variant of a technique for enhancing the validity of self-reports--the generalized bogus pipeline--was investigated in three experiments, with a total of 273 undergraduates. The construct validity and the efficacy of the technique were supported. The effect size and effects of anonymity were also addressed. (TJH)

Investigated the Type A Behavior Pattern (TABP) in 25 boys of 6-12 years who had attention-deficit hyperactivity disorder (ADHD). ADHD boys obtained higher TABP Total and Impatience- Aggression scores than normal boys. ADHD boys' scores were associated with a wide array of behavior problems and peer difficulties. (RJC)

Australian business students (n=200) completed the Student's Orientation Questionnaire and Learning Preference Assessment (LPA). Results from correlation analysis supported the LPA's construct validity. The LPA is an effective measure of self-directed learning readiness in students over 20, but doubts exist about its use with those under 20. (SK)

The effect of the conditioning score on the results of differential item functioning (DIF) analysis was examined with simulated data. The study demonstrates that results of DIF that rely on a conditioning score can be quite different depending on the conditioning variable that is selected. (SLD)

This simulation study considered the effects on statistical measures of test dimensionality that result from systematic sampling variation in both a single- and a double-trait assessment model. Results suggest that there are distinct psychological and psychometric states of test dimensionality, and that psychometric unidimensionality may be…

Presents the role of human resource development practitioners as organizational researchers. Describes a model for validating instruments, constructs, and strategies, based on communication theory. Cites common errors and issues in the validation of measurement and demonstrates uses of the heuristic validation model. (SK)

Explored construct validity of computer-assisted battery of neuropsychological tests with 82 psychiatric inpatients and 89 normal volunteers. Principal components analysis of inpatients scores revealed simple reaction time, response accuracy, visuomotor skill, and complex processing and memory components. Found similar factorial structure in…

A historicodevelopmental model of acquisition order of words was applied to 175 words comprising the Peabody Picture Vocabulary Test--Revised. A structural equation model demonstrates that the combination of date of entry into English, word length, polysemy, and frequency of use account for a substantial proportion of variance of acquisition…
