Changes in sensation seeking and need for structure before and after a combat deployment.

n this study, soldiers’ adaptation with the situational demands on combat deployment is explored. Certain changes on the level of two needs-based personality characteristics, Sensation Seeking (SS) and Need for Structure (NS) take place across deployment: soldiers who are lower in SS were more inclined to seek for sensations after deployment, and soldiers at the extremes of the NS dimension, modified their behavioral tendencies after deployment towards a moderate level. According to our findings, these changes suggest at least temporal characteristic adaptations with certain environmental demands. We discuss the implications of these findings for research and practice
