BACKGROUND: Repeated injury, or recidivism, because of intentional or unintentional injury is a growing chronic health problem among urban adolescents and young adults in the United States. OBJECTIVE: To describe demographic, social, environmental, psychological, and developmental antecedents and risk-taking behaviors, and to examine their relationships to type of trauma and rate of trauma recidivism in adolescent and young adults in an urban trauma center. METHODS: One hundred adolescent and young adult trauma victims in an urban trauma center were interviewed, using the Adolescent Risk-Taking Instrument, the Brief Anger/Aggression Questionnaire, and the Trauma Risk Factor Interview Schedule. Bivariate correlation, multiple regression, and discriminant function analysis were used to examine the data. RESULTS: Of the sample, 89% experienced trauma related to interpersonal violence, including firearm injuries, stab wounds, and blunt trauma. Male gender, unemployment, past arrest, lower levels of spirituality, and higher levels of anger/aggression and thrill-seeking accounted for 25% of the variance in the number of risk-taking behaviors. Factors such as male gender, past arrest, unemployment, having been a crime victim in the past, lower autonomy, use of weapons, fighting, and no psychological counseling distinguished subjects with firearm-related injuries from subjects with other injury sources. Use of alcohol on weekdays, past arrest, and higher education levels were associated with trauma recidivism, explaining 14% of the variance. CONCLUSIONS: Social/environmental and psychological/developmental variables, as well as risk-taking behaviors, are important correlates of trauma and recidivism. These findings suggest the importance of advocacy for social policies conductive to reducing the risks of violence and trauma and risk-reduction interventions as components of posttrauma care.

Recent research suggests human life history strategy (LHS) may be subsumed by multiple dimensions, including mating competition and Super-K, rather than one. In this study, we test whether a two-dimensional structure best fit data from a predominantly urban sample of young adults ages 18–24. We also test whether latent life history dimensions are associated with environmental harshness and unpredictability as predicted by life history theory. Results provide evidence that a two-dimensional model best fit the data. Furthermore, a moderate inverse residual correlation between mating competition and Super-K was found, consistent with a life history trade-off. Our findings suggest that parental socioeconomic status may enhance investment in mating competition, that harshness might persist into young adulthood as an important correlate of LHS, and that unpredictability may not have significant effects in young adulthood. These findings further support the contention that human LHS is multidimensional and environmental effects on LHS are more complex than previously suggested. The model presented provides a parsimonious explanation of an array of human behaviors and traits and can be used to inform public health initiatives, particularly with respect to the potential impact of environmental interventions.

Although the risk-taking can potentially result in positive and negative outcomes, most of the researchers focused on its negative, not positive manifestations. Recently, Duell and Steinberg proposed a framework that clarifies the features of positive risk-taking. Research comparing positive and negative risk-taking increased and new measures have been developed. The presented study was designed to examine how the construct of positive risk-taking differs or overlaps with its opposite, negative risk-taking, and whether both are predicted by the same or different factors. Two hundred fifty eight (258) adolescents and young adults (aged 16-29) participated in the study. We tested self-reported sensitivity to reward and punishment, self-control, tolerance to ambiguity, trait anxiety, and gender as possible predictors of positive and negative risk-taking. We also referred both types of risk-taking to domain-specific risk-taking. We found that positive risk-taking is driven by sensitivity to reward and tolerance to ambiguity, and occurs especially in the social domain. Negative risk-taking is driven by gender, sensitivity to reward and (low) sensitivity to punishment, and occurs in all domains except social. Results indicate that positive risk-taking is chosen for exploration and personal growth by people who look for rewards in the social world and is done in a socially accepted way. Negative risk-taking is chosen by people who are not discouraged by severe negative effects and look for rewards outside existing norms.

AbstractI applaud Singh's proposition to use evolutionary psychology to explain the recurrence of shamanistic beliefs. Here, I suggest that evolutionary mechanisms (i.e., life history theory) also can explain the variability of the distribution of shamanism. When resources are abundant, individuals become more patient and more open minded to the point that science becomes cognitively attractive and may replace magic.
