[Assessment workaholism as a behavioral tendency: the Polish adaptation of the Mudrack and Naughton questionnaire].

INTRODUCTION: There are many approaches to workaholism presented in the scientific literature. The behavioral developed by Mudrack and Naughton is one of them. The authors understand workaholism as a tendency towards unnecessary activity that is not expected by an employer and intrusive strive for control over co-workers. Mudrack and Naughton developed the diagnostic tool for workaholism measurement. This is an 8-item questionnaire consisted of two subscales named: non-required work and control of others. The operationalisation of the workaholism phenomenon proposed by the authors seems to be the subject of interest to both scientists and practitioners. It allows for quick and easy diagnosis of the problem and also offers tools for behavioral change of unhealthy activities. That is why, the Polish adaptation of this questionnaire has been decided.

METHODS: The following analyses were applied: item analysis, explanatory and confirmatory factor analyses and the reliability of scales were calculated.

RESULTS: This paper presents stages of the adaptation study which has resulted in the construction of a 12-item questionnaire.

CONCLUSION: The Polish version of Mudrack and Naughton's tool, like the original, has a two-factor structure, and preliminary psychometric properties seem to be satisfactory (Cronbach alfa = 0.87).
