Test development and validation.

Abstract

For more than 100 years, psychologists have measured human behavior, thought, feelings, and personality. The context in which tests and assessment measures are used in clinical psychology is extraordinarily broad. The aspects of human behavior assessed include intellectual behavior, neuropsychological functioning, observation of behaviors, personality, attitudes, interests, values, and the like.This chapter concerns test development and validation. It focuses on the most common types of psychological testing used in clinical psychology: self-report inventories (Ben-Porath, 2013). Such inventories are typically expected to assess personality, psychopathology, or both.
