ScaleArch is a tool guiding through the basic analyses needed to evaluate and document the validity of a scale as a research instrument. Using an example scale with continuous indicators, it provides hands-on guidance for computing descriptive statistics, exploring the dimensionality of items, fitting confirmatory factor models, and estimating reliability coefficients.

Further information: This tool was developed as part of the KODAQS project, a partnership between GESIS, the University of Mannheim, and LMU Munich.
