Abstract

AIM: This paper presents the construction, validation and psychometric properties of the Polish basic version of a workplace bullying questionnaire (called the SDM questionnaire ¹ 1. The abbreviations used in the text: SDM (for the bullying questionnaire name), SDM-IDM and SDM-ODC (for the names of the bullying questionnaire scales) come from the Polish language and should be treated as proper names. Thus, for the sake of consistency, they cannot be changed or translated into English. ).

METHOD: The tool was developed in phases, in reference to the international bullying literature and Polish socio-organisational background. The study from 2005/2006 (N = 347) established the structure of the scales' reliability, while the questionnaire's convergent validity was tested in 2018 (N = 500). Among the main statistical methods used were: exploratory factor analyses, estimation of internal consistency with Cronbach's α and correlations analyses.

RESULTS: The main version of the SDM questionnaire comprises two consistent, correlating scales: the main behavioural scale (SDM-IDM scale; 43 items; Cronbach's α = 0.96) used for diagnosing exposure to bullying behaviours and an auxiliary emotional-cognitive scale (SDM-ODC scale; 21 items; Cronbach's α = 0.97), which completes the psychological picture of bullying interaction Each of these scales may be divided into three, more specific subscales. All the SDM questionnaire scales positively correlate with the Negative Acts Questionnaire-R (NAQ-R) and with three self-report measures of job stressors.

CONCLUSION: The SDM questionnaire is an accurate and reliable psychometric tool for measuring workplace bullying in Polish conditions.
