Creating and Validating Rapid Assessment Instruments for Practice and Research: Part 1

Abstract
In this age of accountability, social work practitioners face greater demands to demonstrate the effectiveness of their interventions. A practical way to accomplish this is to use rapid assessment instruments (RAIs) to measure a client’s level of functioning so that any subsequent change in functioning can be accurately detected over time. Although great strides have been made during the past three decades in the development of RAIs, there remains a paucity of reliable and valid scales when compared to the increasingly complex range of problems that practitioners confront in their day-to-day work with clients. This article, the first in a two-part series, outlines how to conceptualize and create a scale and how to plan and subsequently implement a design testing the newly created scale’s reliability and validity. The second article in this series provides illustrations of these steps from the authors’ own works, detailing decision making and strategies for analyzing psychometric data.
