Examined the utility of the aggregation method as a measure of behavioral consistency in 26 studies involving computer-generated, repeated-measurement data. Concluded that aggregation produces spuriously high estimates of behavioral consistency. The Spearman-Brown prophecy formula and coefficient alpha accurately predict the results of the…

Most psychological tests and inventories, particularly in personality and attitude measurement, contain common items. The present report specifically considered common-item contributions to test internal consistency reliability using extant data from the California Psychological Inventory. No negative contribution of item overlap was found.…

The Kinesthetic Aftereffect (KAE) has been criticized as a personality measure because of its poor retest reliability and questionable validity. However, KAE's lower reliabilty can be explained by systematic bias effects occuring in pretesting. When the validity evidence is reevaluated in this light, "questionable" validity disappears.…

Reports progress in the development of the Needsort, a research tool, for the assessment of the three developmentally earliest, within Maslow's framework, conative needs (physiological, safety, belongingness). Discusses item analyses, item selection methods, reliability studies, and validation studies across a broad range of populations. (Author)

Three studies investigating the psychometric and conceptual properties of the self-report Survey of Ethical Attitudes inventory indicated that the scale is clearly susceptible to response dissimulation through role playing and impression management and is also confounded with sources of stylistic variance in the form of social desirability.…
