Sensation seeking and risk behaviors in young adults with and without a history of head injury.

Research has demonstrated a relation between sensation seeking and risky behavior as well as an association between risky behavior and the occurrence of head injury. This study assessed sensation seeking in young adults with and without a history of head injury by administration of the Sensation Seeking Scale (SSS), the Driver Risk Index (DRI), and the MacAndrews Scale of the Minnesota Multiphasic Personality Inventory (MMPI). There was a significant difference between the groups for the Thrill and Adventure Seeking Subscale of the SSS and the MacAndrews Scale of the MMPI, with head-injured participants scoring higher. Gender differences were seen in both groups for subscales of the SSS, with men scoring higher. Significant correlations were found for head-injured participants between the DRI and the Boredom Susceptiblity Subscale of the SSS, suggesting that as knowledge of risk increased for these participants, so did their preferences for risky behaviors. However, non-head-injured participants indicated a lower interest in risky behaviors as their knowledge of risk increased.
