The concurrent validity of the Lund University Checklist for Incipient Exhaustion and the Karolinska Exhaustion Disorder Scale: a replication study

Abstract

Objective: As part of our research on Swedish school principals, we examined the concurrent validity between the Karolinska Exhaustion Disorder Scale (KEDS) and the Lund University Checklist for Incipient Exhaustion (LUCIE) in a cross-sectional study sample (N = 2670). Specifically, we examined: (a) to what extent LUCIE and KEDS identified the same individuals and their level of agreement, and (b) to what extent the present observations among school-principals agreed with previous observations made in a highly educated and healthy study sample drawn from the general population. Results: Depending on established cut-points on LUCIE, the Kappa agreement (K) between LUCIE and KEDS varied between fair (K = 0.34 [95% Confidence Interval = 0.30–0.38]) and moderate (K = 0.54 [95% Confidence Interval = 0.51–0.58]). While the instruments did not always identify the same individuals, the most reasonable comparison between KEDS and LUCIE was achieved when the cut-off on LUCIE was made between step two and step three. The results essentially replicated our previous results observed in a highly educated and healthy study sample drawn from the general population. The level of agreement suggests that KEDS and LUCIE scores are supplementary rather than interchangeable. Thus, individual result from KEDS and LUCIE are probably best understood in dialogue with the person screened.
