This document contains four symposium papers on measurement and research tools. "Income Effects of Human Resource Development for Higher Educated Professionals" (Martin Mulder, Bob Witziers) reports on a study of 1,876 higher-educated professionals that found no correlation between participation in human resource development activities and subsequent job level or income. "Do Higher Performing Managers Actually Receive Better Ratings? A Validation of Multirater Assessment Methodology" (Allan H. Church), which is an applied example of a validation process based on a sample of 76 senior-level managers from a global health services organization, confirms the relationship between managerial performance and higher ratings on multirater feedback instrumentation. "Examination of the Tendency of Coefficient Alpha to Support the Choice of Instruments with Response Category Restriction" (Shani D. Carter) demonstrates that interpretation of coefficient alpha and the decision to use an instrument can be improved by considering item construction before deciding to use an instrument. "A Factor Analytic Investigation of the Content of Participant Reactions: Affective and Utility Judgments" (Ronald B. Morgan, Wendy Casper) presents the results of a study suggesting that participant reactions are multidimensional and "utility" judgments represent an underlying factor. (MN)
