  • Sandra Ohly & Zan Strabac

EAWOP 2007, Stockholm


Overview
Overview

  • Karasek model

  • Research questions and hypotheses

  • Sample and method

  • Results

  • Implications


Prior research
Prior research

  • Model supported for health outcomes

  • Mixed support for psychological well-being and active behavior

  • Problem

  • mostly homogeneous samples

  • mostly from single European countries


Hypotheses
Hypotheses

  • Well-being:

  • Job control will be positively related to general psychological well-being.

  • Job demands will be negatively related to general psychological well-being.

  • Job demands and job control will shown an interactive effect on general psychological well-being.

  • mean level of education = 13.2 years (SD = 3.56)

  • Methodological advantages

  • large, representative, cross-national samples

  • Methodological challenges

  • quality of measures; clustering (VPCwell = 9%)


Measures
Measures

  • Well-being „How happy/satisfied are you with your life?“ a = .65

  • Proactive behavior „Have you made any attempt to improve conditions at work?“

  • Job control „ ... organize your own work“ a = .87

  • Job demand: Working hours, overtime included

  • Controlling for

  • Age

  • Gender

  • Living with partner

  • Supervisor position

Results: Well-being

  • Delta R-square Beta

  • Controls 9.8 %

  • Job control 2.2 % .007***

  • Job demand -.010**

  • Interaction 0.2% .004*


Proactive behavior
Proactive behavior

  • Delta R-square Beta

  • Controls 7.5 %

  • Job control 2.2 % .157***

  • Job demand .003

  • Interaction 0.0 % .001
