Adolescent impulsivity is a risk factor of attack behaviors and antisocial behaviors. Previous studies showed negative correlation between impulsivity and central serotonin. The purpose of this study was to examine the relations between the impulsivity of questionnaires and the salivary serotonin concentration. Subjects were 175 undergraduate students who were measured SSS (Zuckerman et al., 1978) and TCI (Cloninger et al., 1993). Furthermore 53 students of them were measured NEO-PI-R (Costa & MaCrae, 1992) and the salivary serotonin concentration. The correlational analysis showed that salivary serotonin was significantly associated with SSS and NEO-PI-R, salivary serotonin concentration was not significantly associated with TCI. Those results showed the discrepancy of TCI and SSS concerning the impulsivity and the serotonin concentration. This is the first report using the salivary serotonin concentration as a psychophysiological assessment tool for the adolescent impulsivity.
