some use in Germany. In 2006, Shirom and Melamed with their Shirom-Melamed Burnout Measure (SMBM) conceptualized burnout in terms of physical exhaustion, cognitive weariness, and emotional exhaustion. An examination of the SMBM's emotional exhaustion subscale, however, indicates that the subscale more clearly embodies Maslach's concept of depersonalization than her concept of emotional exhaustion. This measure has seen little use. In 2010, researchers from Mayo Clinic used portions of the MBI, along with other comprehensive assessments, to develop the Well-Being Index, a nine-item self-assessment tool designed to measure burnout and other dimensions of distress in healthcare workers specifically. It has been mainly used in the United States. In 2014, Aniella Besèr et al. developed the Karolinska Exhaustion Disorder Scale (KEDS), which is used mainly in Sweden. It was designed to measure the symptoms defined by the ICD-10-SE's category for exhaustion disorder. The authors believed that those with the disorder were often initially depressed, but that this soon passed. The core symptoms of the disorder were deemed to be "exhaustion, cognitive problems, sleep disturbance". The authors also believed that the condition was clearly differentiated from both depression and anxiety. In 2020, the Occupational Depression Inventory (ODI), was developed to quantify the severity of work-attributed depressive symptoms and establish provisional diagnoses of job-ascribed depression. The ODI covers nine symptoms, including exhaustion (burnout’s putative core). The instrument exhibits robust psychometric properties. The ODI is the only instrument that assesses work-related suicidal thoughts, a particularly important symptom calling for immediate attention. Available evidence indicates that burnout scales have very high correlations with the ODI, correlations that cannot be explained by item overlap, suggesting that the ODI is a suitable replacement for burnout scales like the MBI. In 2021, the Sydney Burnout Measure (SBM) was released by Gordon Parker et al., which "captures domains of exhaustion, cognitive impairment, loss of empathy, withdrawal and insularity, and impaired work performance, as well as several anxiety, depression and irritability symptoms." There are still other conceptualizations as well that are embodied in other instruments, including the Hamburg Burnout Inventory, and Malach-Pines's Burnout Measure. Kristensen et al. and Malach-Pines (who also published as Pines) advanced the view that burnout can also occur in connection to life outside of work. For example, Malach-Pines developed a burnout measure keyed the role of spouse. The core of all of these conceptualizations, including that of Freudenberger, is exhaustion. Maslach advanced the idea that burnout should
