Construct Validity of the EPICS Scales across Groups: A MIMIC Modeling Investigation Abstract Using the Multiple Indicators, Multiple Causes (MIMIC) modeling approach, this
study focused on the investigation of the construct validity of the Engineering Projects in
Community Service (EPICS) program evaluation instrument. Possible differential item
functioning (DIF) among the observed items were detected and described. The extent to
which EPICS students’ gender and major are related to their evaluation on the
professional skills and outcomes defined by the Accreditation Board for Engineering and
Technology’s Engineering Criteria 2000 (ABET EC2000) Criterion 3 was analyzed.
Results indicated that the instrument has acceptable construct validity evidence, and in
general gender and major were not predictive of students’ noncognitive measures (e.g.,
communication and teamwork skills) on the EPICS program evaluation subscales.
Background and Theoretical Framework First established at Purdue University in 1995, the EPICS program aimed to
integrate engineering undergraduate student teams into local community service multi-
disciplinary service learning projects. Within EPICS program, teams of undergraduates
design, build, and deploy real systems to solve engineering-based problems for local
community service and education organizations 1 . It is now operating at 15 universities
nationwide with over 1350 students participated 1 .
Accreditation Board for Engineering and Technology’s Engineering Criteria 2000
(ABET, 1999) Criterion 3 2 Programs Outcomes and Assessment specifies outcomes
college graduates are expected to know and demonstrate from accredited engineering
programs. The generality of Criterion 3 objectives require engineering programs to
articulate desired program outcomes related to professional skills that the participants can
