Summary/Abstract: Decision making styles do not mediate the relationship between perceived stress and subjectively assessed effectiveness of decision making. Melbourne Decision Making Questionnaire (MDMQ) is one of the most used measures for the assessment of decision making styles. It is based on conflict theory, which states that the level of stress during making decisions affects the use of adaptive or maladaptive decision making styles, subsequently affecting decision making effectiveness. This study aims to test conflict theory by testing the mediation effect of decision making styles in the relationship between perceived stress and subjective decision making effectiveness of decisions (SDME). Data were collected in 2010 among Slovak health care professionals: nurses, paramedics and emergency links operators (N=206, mean age 39.4 years; SD 9.5 years; 22.5% males). Perceived stress was measured by a 10-items version of Perceived Stress Scale, decision making styles by the MDMQ, and SDME by a 100 mm visual analogue scale. Perceived stress was negatively associated with SDME (r=0.32; p<0.001). Only two of the four decision making styles (procrastination and hypervigilance) were significantly associated with both perceived stress and SDME. The mediation effect was not confirmed in any of these two styles. Although the self-reported and cross-sectional nature of this study and a big conceptual overlap among the studied variables are limiting factors, the results of our study question the validity of conflict theory as applied in the MDMQ.
