An Introduction to Psychological Tests and Scales
The widely used methods handbook, now in its third edition (with Christopher Alan Lewis; Routledge, 2020). A clear, jargon-free primer that teaches how to find, choose and build sound self-report measures of the things psychologists study, beliefs, attitudes, moods, values and skills, with step-by-step guidance from writing items and entering data through to reliability, validity and techniques as advanced as factor analysis and multiple regression. Written for students and researchers in psychology and neighbouring fields.
