This chapter provides an overview of important issues and procedures in the construction and implementation of measures of personality and psychopathology. The majority of examples used to illustrate various principles described in this chapter involve the use of objective or self-report methods of personality, as this approach has historically served as the basis for many of the most important theoretical psychometric developments in the field of personality assessment. The chapter reviews different approaches to test construction and procedures used to develop and evaluate indicators included on these instruments. Subsequent sections discuss approaches and considerations in evaluating the usefulness of an assessment measure, such as reliability and validity. In addition, the chapter discusses the impact of the nature of the constructs being measured on the development and evaluation of indicators of that construct. Finally, a number of the pitfalls confronting the scale developer are described, with an emphasis on the understanding that different assessment problems reflect unique challenges with diverse solutions.
