The aim of the study was to find: 1) the relationship between the basic components of the basal mental personality integration (cognitive, emotional, regulatory and adjusting variability), factors of general personality variability (general mental arousal, motoric dynamics) and styles of coping with decisional conflict in decision-making (vigilant, hypervigilant behavior, buck-passing and procrastination) in paramedics, 2) stability, or variability of occurrence of identified relationships among paramedics with different length of experience. Sample: 134 paramedics, age: 22 -51 years, AM = 33.22, SD = 6.26. Methods: Melbourne Decision-Making Questionnaire, MDMQ , Questionnaire SPARO (Mikšík, 2004).
