Psychometrics Overview

The UniLOA is an indirect measure of student learning outcomes, as is any instrument designed to collect self-report data. Because of the inherent challenges posed by attribution error, the results of any self-report instrument should not be relied upon as a wholly accurate measure of actual outcomes. However, any effective assessment protocols should include collection of multiple data points, including both indirect and direct measures. The UniLOA, when triangulated with other measures of student learning outcomes will provide a far better understanding of the degree to which students are achieving desirable learning outcomes.

Because the UniLOA reflects the desires of broad constituencies having an interest in student growth, learning, and development (including employers, higher education faculty and administrators, accrediting agencies, parents, and students themselves) and is consistent with contemporary empirical research in student development, its content validity is high.  Findings of the UniLOA continue to be consistent with findings of other human and student development research which supports a high degree of concurrent validity.

The UniLOA's high degree of external reliability is strongly supported as response patterns are consistently replicated.

Internal reliability estimates for each of the seven domains are:

The UniLOA’s seven domains are of interest to institutions of higher education. Because of the constructs measured, the UniLOA’s utility stretches far beyond the basic data set its results produce. The UniLOA itself can be used as an anchor point to measure programs and supports from across campus. Programming can be developed to bolster GLD in any of the UniLOA’s domains as a whole, or by targeting one of more individual items. In that sense, the UniLOA provides diagnostic data as well as offering guidance for prescriptive responses.

Many assessment instruments measure individuals’ cognitive state by asking questions dealing with perceptions, beliefs, and affective states.  While cognition and affect are appropriate to measure, the UniLOA's authors believe that student GLD is most accurately reflected in actual behaviors.  The construction of the UniLOA’s individual items are purposely built with a cognitive trigger to assist the student in understanding an underlying construct, and a behavioral stem, which asks the test-taker to report actual behaviors, making the UniLOA unique in the means by which it measures GLD.

 A 10-point Likert-like scale is used to answer each item on the UniLOA, which produces the practical equivalent of a ratio scale from which scores can be derived and appropriately interpreted.
