Riassunto

A best-seller in its First Edition, Scale Development: Theory and Applications, Second Edition has been extensively updated and revised to address changes in the field and topics that have grown in importance since the First Edition. Widely adopted for graduate courses in departments such as Psychology, Public Health, Marketing, Nursing, and Education, this book will prove beneficial to applied researchers across the social sciences. New to the Second Edition are figures and practical tips for students, a new section on face validity (Chapter 4), a substantially expanded presentation of factor analysis (Chapter 6), a new chapter (7) on item response theory (IRT), coverage of qualitative procedures, and issues related to differential item functioning (Chapter 8).
