IMPAQ Senior Research Analyst Vincent Chan will present “Building Macros for Quick Survey Scoring” at the Western Users of SAS® Software Conference, taking place in Long Beach, California from September 20-22. Join Vincent for his presentation on September 21 at 2 PM in Regency D (Advanced Tech).
Survey developers create surveys using psychometric principles to ensure the reliability and validity of each question, also known as an ‘item.’ A developer can purposefully create sets of items, which when analyzed as a group, can measure a construct that describes the underlying behavior, attribute, or characteristic of a study participant. The programmer calculates the construct score by combining component items of the construct.
The programmer is tasked with creating such scores quickly. With an unlimited amount of time to spend, a programmer could operationalize the creation of these constructs by manually entering predefined formulas in the DATA step. More often, time and resources are limited. Therefore, the programmer is more efficient by automating this process using macro programs. In this paper, we present a technique that uses an externally created specification Excel file (spec) that contains the construct specifications and corresponding items of each construct.
