While many studies examine the mean score differences of psychological determinants between heterogeneous driver groups, this study reveals a structural discrepancy in a causal behavioral framework. Using young motorcyclists (ages 18-28) as subjects, this study investigates the various roles of key influential factors in determining risky driving behavior. Multi-group analysis of structural equ...

The present review argues that, popular lore notwithstanding, the well-documented association between usual patterns of alcohol use and risky sex reflects multiple underlying processes that are both causal and noncausal (spurious) in nature. It is further argued that even alcohol’s acute causal effects on sexual behavior are more variable than they are commonly assumed to be. Drinking can promo...

DESIGN AND METHODS A prospective cohort study was performed in rural Uganda. Between May 2003 and December 2004 a...

OBJECTIVE The aim of this review was to gain insight into the relationship between Attention deficit hyperactivity disorder (ADHD) and risky performance in gambling tasks and to identify any potential alternate explanatory factors.

a r t i c l e i n f o Despite numerous studies on the myriad of psychosocial factors that affect youthful offenders, research on gender differences with respect to risky sexual behavior are limited. Using data on juvenile offenders in a residential facility , we analyzed impact of gender on sexual behavior (N =227). Girls reported higher likelihood of diagnosis with sexually transmitted disease...

We use an economic experiment to examine the impact of an ambiguous level of asymmetric information on the behavior of security dealers. Specifically, we distinguish three types of uncertainty with respect to informed trading: risk, compound risk, and ambiguity; for both a monopoly and a duopoly market setting. We find that dealer’s bidding behavior is less aggressive under an ambiguous level o...

This study interviewed 2,272 women from a low income community in California, USA who completed a questionnaire entitled Risk Behavior Assessment that captured risky drug and sexual behavior. The logistic regression model included gonorrhea, chlamydia, syphilis, warts, crack, and sex trading for money as well as racial and ethnic differences. It was evident that Trichomonas Vaginalis can co-exi...

Financial risky decisions and evaluations pervade many human everyday activities. Scientific research in such decision-making typically explores the influence of socio-economic and cognitive factors on financial behavior. However, very little research has explored the holistic influence of contextual, emotional, and hormonal factors on preferences for risk in insurance and investment behaviors....

In a randomized experiment, women (N = 441) watched either a loss- or gain-framed video emphasizing the prevention or detection functions of the Pap test to test the hypothesis that loss- and gain-framed messages differentially influence health behaviors depending on the risk involved in performing the behavior. As predicted, loss-framed messages emphasizing the costs of not detecting cervical ...
