The assignment of job-attitude items to subscales.

An attitude questionnaire, for use with the personnel of a Great Lakes shipping concern, was constructed using rational judgments to assign items to areas of the questionnaire. The areas were nominally those suggested as invariant by Wherry. The degree of agreement between the rational sort and the areas named from the invariant factor characteristics was determined. Attitude characteristics of the surveyed group as well as mechanical and response artifacts are suggested as providing partial explanations of the differences found. Items identified as critical through use of several item indices are compared to evaluate index utility. (16 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
