INFORMATION SYSTEMS DATABASE (ISDB) is an open database project introduced in 2017. The Goal of ISDB is to support fellow researchers in finding established research constructs and items. ISDB holds over 2.250 research constructs and over 100.000 items that are used in high quality research. Keep in mind, in the context of survey research, a construct is the abstract idea, underlying theme, or subject matter that one wishes to measure using items (e.g. survey questions). The database is permanently updated with new developments in information systems. Due to the fact that database is maintained volutary any donation is highly appreciated. When you use ISDB we further appreaciate a respective citation: C. Mittendorf, U. Ostermann, F. Franzmann (2017), Information Systems Database (www.is-database.com). Thank you very much. Your ISDB-Team.
