PREFACE
This text was prepared for the affective component of a graduate level
course in affective and cognitive instrument development. The techniques
described, and the data sets included, represent attempts over several years
to prepare materials that would illustrate proper instrument development
techniques in the affective domain. The need for this text became apparent
after witnessing severallarge-scale research projects that were hindered by
inadequately prepared instruments. Researchers in these projects were
often not aware of the need to use appropriate procedures in developing
affective instruments; furthermore, they could rarely, if ever, locate a com
prehensive and readable text that could help. This text was developed to
meet this important instructional need.
Chapter 1 discusses the importance of affective variables and presents
conceptual definitions of major affective constructs such as attitudes, self
concept, interests, and values. Chapter 2 outlines and illustrates the domain
referenced approach for developing operational definitions (i.e., items)
for the targeted conceptual definitions. Chapter 3 addresses the important
area of scaling the affective characteristics in the context of Fishbein's
expectancy-value model. The Thurstone, latent-trait, Likert, and semantic
differential techniques are included along with a section on normative versus
ipsative measures.
Chapters 4 and 5 present the underlying theory and appropriate empirical
techniques appropriate for examining validity and reliability evidence. Data
gathered by the author, using several different instruments, are included to
i1Iustrate each technique. Annotated SPSSx computer output for the Factor
and Reliability programs is included for examining construct validity using
factor analytic techniques and alpha internal consistency reliability. Actual
item analysis and reliability data from the SPSSx Reliability program are
