Specific associations among perceived stress and hardiness can reflect the characteristics of workers in particular professions. The goals of this research were to analyze sets of correlations between the aspects of hardiness and experienced stress, separately for two subsamples of subjects in the research, and on the entire sample. Then, the goal was to determine the correlations among the aspects of stress and hardiness, with three variables: age, work experience and number of children. A correlative study was conducted in Croatia on two samples: 75 nursing and 63 criminology students, using Stress-test (ST) and Short Hardiness Scale (SHS). The results showed low and negative correlations among two aspects of hardiness and the dimensions of stress. Aspects of hardiness was not correlated with the dimension of diet and sleep difficulties. There are no statistical significant correlations between age, work experience and number of children with stress. The aspect of control becomes lower emphasized with age, mainly at nurses.
