Research on personality and circadian typology indicates evening-type women are more impulsive and novelty seeking, neither types are more anxious, and morning types tend to be more active, conscientious, and persistent. The purpose of this study is to examine the differences between circadian typologies in the light of the Zuckerman's Alternative Five-Factor Model (AFFM) of personality, which ...

Sensation seeking is a personality trait that has been associated with disinhibited behaviours including substance use and gambling, but also with high-risk sport practices including skydiving, paragliding, and downhill skiing. Twin studies have shown that sensation seeking is moderately heritable, and candidate genes encoding components involved in dopaminergic transmission have been investiga...

This study tested derivations from Cloninger's (1987a) theory of substance use on a sample of 457 adolescents. A 67-item adaptation of the Tridimensional Personality Questionnaire (TPQ) and measures of 10 related constructs were administered together with measures of tobacco, alcohol, and marijuana use. Factor analysis indicated that the TPQ comprised nine subscales. An interaction for TPQ dime...

Sensation seeking is associated with an increased propensity for delinquency, and emerging research on personality change suggests that mean levels of sensation seeking increase substantially from childhood to adolescence. The current study tested whether individual differences in the rate of change of sensation seeking predicted within-person change in delinquent behavior and whether genetical...

Men score higher than women on measures of sensation-seeking, defined as a willingness to engage in novel or intense activities. This sex difference has been explained in terms of evolved psychological mechanisms or culturally transmitted social norms. We investigated whether sex differences in sensation-seeking have changed over recent years by conducting a meta-analysis of studies using Zucke...

Patients with bipolar disorder have tendencies of higher impulsivity and sensation seeking, they might contribute differently to the emotional states of bipolar I (BD I) and II (BD II). We administered the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ), the Plutchik-van Praag Depression Inventory (PVP), the Mood Disorder Questionnaire (MDQ), and the Hypomania Checklist (HCL-32) in 23 patien...

Although there are indications that ecstasy users have higher levels of depression, impulsivity, and sensation seeking, it is unknown whether these are consequences of ecstasy use or predisposing factors for starting ecstasy use. We prospectively assessed the predictive value of depression, impulsivity, and sensation seeking on future first time ecstasy use. We also assessed whether depression,...

Sensation seeking is a strong correlate of alcohol consumption among young people, yet the research on mediators of this association is mainly limited to English-speaking adolescents. The proposed model of the present study includes antecedent variables (sensation seeking, age and gender), mediators (positive and negative expectancies and drinking motives), and one outcome variable (a composite...

Previous studies examining sex and age-related differences in sensation seeking havemainly focused on specific patterns of behaviour that can be described as a youthful behaviour style. In contrast, the present study assessed age and sex differences in sensation seeking using the need inventory of sensation seeking (NISS). This instrument measures sensation seeking without items which are descr...
