Abstract:	Background The aim of the present study was the construction and psychometric evaluation of a shortened version of the Burnout Screening Scales II (BOSS II), a measure for exhaustion and burnout. Methods To this end, among a representative sample of the German general population (N = 2429, 52.9% women), we shortened the scale from 30 to 15 items applying ant-colony-optimization, and calculated item statistics of the short version (BOSS II-short). To estimate its reliability, we used McDonald’s Omega (ω). To demonstrate validity, we compared the correlation between the BOSS II-short and the BOSS II, as well as their associations with depression, anxiety, and quality of life. Furthermore, we evaluated model fit and measurement invariance across respondent age and gender in confirmatory factor analyses (CFA). Finally, we present adapted norm values. Results The CFA showed an excellent model fit (χ2 = 223.037, df = 87, p < .001; CFI = .975; TLI = .970; RMSEA [90%CI] = .036 [.031;.040]) of the BOSS II-short, and good to very good reliability of the three subscales: ‘physical’ (ω = .76), ‘cognitive’ (ω = .89), and ‘emotional’ (ω = .88) symptoms. There was strict measurement invariance for male and female participants and partial strict invariance across age groups. Each subscale was negatively related to quality of life (‘physical’: r = −.62; ‘cognitive’: r = −.50; ‘emotional’: r = −.50), and positively associated with depression (‘physical’: r = .57; ‘cognitive’: r = .67; ‘emotional’: r = .73) and anxiety (‘physical’: r = .50; ‘cognitive’: r = .63; ‘emotional’: r = .71). Conclusions Overall, the BOSS II-short proved to be a valid and reliable instrument in the German general population allowing a brief assessment of different symptoms of exhaustion. Norm values can be used for early detection of exhaustion.
