What it’s about

This book serves as an accessible pocket guide for practitioners, students, and researchers in social work and the behavioral sciences who need to create or validate measurement scales. It demystifies the complex process of psychometrics by breaking it down into a logical sequence of manageable steps, from initial instrument design and construct conceptualization to the rigorous statistical analysis required to establish reliability and validity. Grounded in established standards and classical measurement theory, the authors provide clear explanations and applied examples for crucial techniques such as reliability analysis, exploratory and confirmatory factor analysis, and establishing various forms of validity evidence. Whether you're developing a new tool to measure a clinical problem or seeking to validate an instrument for a research study, this book provides the essential knowledge and practical guidance to produce psychometrically sound rapid assessment instruments.

The through-line

Who it’s for
A social work practitioner, researcher, or graduate student who wants to create a credible and useful way to measure a complex client problem, a program outcome, or a theoretical construct for their work.
The problem
They lack a clear, practical, and step-by-step process for developing a measurement instrument that is psychometrically sound. They feel intimidated by the statistical complexity of psychometrics and are uncertain how to properly design, execute, and interpret a validation study.
The plan
  1. Define the construct and design the draft instrument using best practices for item generation and formatting.
  2. Design a rigorous validation study with appropriate sampling and a comprehensive data collection plan.
  3. Systematically analyze the data to establish evidence of the instrument's reliability, validity, and factor structure.
The payoff
The reader can confidently develop psychometrically sound instruments that are useful for clinical assessment, program evaluation, and research. · They contribute valuable, evidence-based tools to the social work and behavioral science fields. · Their practice and research are more rigorous, credible, and ethically sound.
