Resquin is a tool for assessing response quality and careless responding in multi-item scales. This tool gives an overview on the assessment of response quality in multi-item scales and guides you through the quality analysis with replicable R-code. It introduces key response quality indicators along with code examples for their calculation, shows how to interpret the different response quality indicators, and assesses their suitability for different question types and response scales. The tool also briefly evaluates different caveats of selected response quality indicators.

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