THE TEST-RETEST RELIABILITY OF USER INVOLVEMENT INSTRUMENTS
It is almost an axiom of the MIS literature that user involvement is a necessary condition for successful development of information systems. Despite this acceptance, Ives and Olson have observed that, hampered by conflicting findings and weak measures, over two decades of research has not convincingly demonstrated the benefits of user involvement. They contend that there is a need to develop reliable and valid measures of user involvement and system success. This paper reports on and extends a program to develop standard user involvement instruments that can measure end-user developed applications as well as others using more traditional methodology. The short-range and long-range stability of instruments that measure perceived involvement, desired involvement, and involvement congruence is assessed via the test-retest method. The results suggest that these instruments are internally consistent, stable, and can be used with confidence in user involvement research without concern about a reactivity effect.
