Die Normative und Subjektive Arbeitsanalyse (NUSA): Psychometrische Eigenschaften in einer repräsentativen Bevölkerungsstichprobe

This paper examines the questionnaire Normative and Subjective Assessment of Working Conditions (NUSA) based on Karasek's model. The purpose of this assessment is to measure the two original dimensionsyoe demands and job decisions latitude and, in addition, physical working conditions as health impacting components. Results concerning its psychometric properties and validity are shown. This investigation is part of the study Transitions in Alcohol Consumption and Smoking (TACOS), a representative general population survey in a northern region of Germany. The current evaluation includes 2,547 working individuals aged 18-64 years. A factor analysis reproduced the two components of Karasek's model and a third scale, physical working conditions. Reliability and internal consistency are good for all three scales. The assessment is sensitive towards differences between relevant groups of occupational status, gender and education. The pros and cons as well as the fields of application of NUSA are discussed.
