The Luxembourg Workplace Mobbing Scale: Psychometric properties of a short instrument in three different languages

Workplace mobbing is a serious phenomenon that is costly to organizations and has various negative consequences of those targeted. The main purpose of the present study was to develop and validate a new short scale of workplace mobbing experience in three different language versions (German, French, Luxembourgish). Data were collected via computer-assisted telephone interviews in a sample of 1500 employees working in Luxembourg (aged from 17 to 64; 52.7 % male) that was representative of the commuter structure of Luxembourg’s workforce. Confirmatory factor analysis showed that the newly developed 5-item scale has good psychometric properties and partial scalar measurement invariance for the three different language versions. Internal consistency was satisfactory (α = .73). Correlations and hierarchical regression analysis with different working condition scales and psychological health scales confirm the construct validity of the new questionnaire. Although the present findings are preliminary in nature, they nevertheless support the reliability and validity of the scale and its use in psychological research.
