The goal of this study was to describe the Croatian Mountain Rescue Service volunteers' personality traits and their motives for volunteering in rescue activities. An online study was carried out on a sample size of N=89 members of the Croatian Mountain Rescue Service and N=89 members of the a comparable group of non-volunteers. A HEXACO-60 personality inventory, a volunteering questionnaire and a socio-demographic data questionnaire were used during the study. The results show that the volunteers' most expressed personality traits are honesty-humility and opennes to experience, while their most expressed motives for volunteering are the motive for expressing one´s own values and the motive understanding. In addition to that, a statistically significant greater expression of the traits honesty-humility and openness to experiences, as well as a statistically significant lower expression of the trait emotionality were shown in the members of the Croatian Mountain Rescue Service compared to the a comparable group of non-volunteers. Lastly, a statistically significant correlation between the volunteers' age and motive career has been proven, as the older volunteers have a statistically significant lower expression of the career motive compared to their younger colleagues. The obtained results point towards the Croatian Mountain Rescue Service volunteers differing from the comparable group in their personality types and that specific motives of value and understanding drive them towards volunteering.
