Stress is an inherent and inextricable aspect of the live. When stress is excessive, it become chronic and has a negative impact on health. There is a need to disseminate knowledge about stress management techniques in order to reduce stress levels. In response to this demand, STRESmission, a psycho-educational tool was designed. It comprises task cards (grouped according to Aristel's triad of soma, psyche and polis), stress event cards (scored based on the Holmes and Rahe stress event scale), power and place cards, and a game board. We have tested if STRESmission (1) reduces perceived stress levels immediately and on a one-off basis, and whether it is an educational tool that helps in the acquisition of coping strategies, (2) can reduce stress levels in the long term, (3) is useful and attractive enough to encourage its use and therefore practical use of its benefits. A series of studies was conducted on groups of University students. We have found that STRESSmission decreased both subjective stress levels (psychological tests) and objective stress levels (lowering cortisol - CORT levels in the saliva). We concluded that the board game could be a stress-releasing and a learning tool to help cope with stressors.
