The present study is in an instrumentation research aimed at adapting and ascertaining the psychometric properties of an existing scale titled Copenhagen Burnout Inventory for University Educators (CBI-UE). In this study, the original instrument developed by Kristensen, Borritz, Villadsen, & Christensen (2005) was adapted. The study was guided by five research questions and four null hypotheses. This instrumentation research design anchored on the classical test theory was used for the study. A convenience sample of 305 university educators drawn from the University of Port Harcourt was used for the study. Cronbach Alpha, Split half, percentile rank, independent sample t-test were used to analyze the data. Findings from the study revealed that the instrument as adapted adequately measured burnout with high internal consistency (0.707), and moderate split half (0.518). The subscales of the instrument also yielded moderate internal consistencies ranging from 0.552-0.675. Construct validity also yielded values as high as 0.814. In addition, the CBI-UE significantly differentiated between male and female, senior and junior, married and unmarried university educators, as well as science based and non-science based educators. Percentile scores were used to establish the norms for the CBI-UE. It was suggested that the instrument should be used with caution in assessing burnout among university educators.
