Risk perception is considered the primary motivator for taking preparedness actions. But people with prior experience and a high‐risk perception are not necessarily more prepared. This relationship is even more complex when assessing preparedness levels for hazards with different characteristics. These inconsistent findings can be explained by how preparedness has been measured and the influence of other factors, such as trust and risk awareness. Thus, the main goal of this study was to analyze the role of risk awareness and trust in authorities on risk perception and intention to prepare for natural hazards in a coastal city in Chile. A representative sample of the city of Concepción, located in the center‐south zone of Chile (n = 585), completed a survey. We measured risk awareness, risk perception, trust in authorities, and intention to prepare for two hazards: earthquakes/tsunamis and floods. Through structural equation models, we tested five hypotheses. We found that the perception of risk maintained a direct and positive influence on the intention to prepare for both hazards. The results showed that awareness and risk perception influence the intention to prepare and should be considered different concepts. Finally, trust did not significantly influence risk perception when faced with known hazards for the population. Implications for understanding the relationship between risk perception and direct experience are discussed. [ABSTRACT FROM AUTHOR]

The association between marijuana use and depressive symptoms was examined longitudinally in a sample of 622 African American youth, interviewed on six occasions, using hierarchical linear modeling (HLM). We considered whether depressive symptoms predicted changes in marijuana use and vice versa from high school through the transition into young adulthood. We also examined gender differences in these behaviors over time. The results indicated that depressive symptoms predicted later marijuana use only for males. Marijuana use did not predict later depressive symptoms for females or males. These findings are consistent with a unidirectional hypothesis indicating that marijuana use may play a role as mood regulator among young males, but not among females. Research findings also indicate that females with lower depressive symptoms use more marijuana than females who report high depressive symptoms. These findings did not change even after controlling for the effects of using other substances at previous stages, school achievement, and demographics factors. These results suggest that depressive symptoms may be an antecedent of marijuana use among African American males.

Objective: The purpose of this study was to examine longitudinally the relationship between depressive symptoms and alcohol use in a sample of black youth. Method: Participants were 458 black males and females interviewed annually during the high school years and then for 3 years during the transition to adulthood. The relationship was examined using growth curves with Hierarchical Linear Modeling. Results: The results suggest that depressive symptoms decrease over time, whereas the use of alcohol increases. The findings also suggest that youths use alcohol as a way to cope with depressive symptoms and that males are more likely to use alcohol as self-medication. The results also indicate that changes in alcohol use do not predict depressive symptoms, but that life changes associated with the transition to adulthood, such as attending college, predict changes in depressive symptoms and alcohol use. Conclusions: Findings highlight the role of depressive symptoms for predicting alcohol use among black youth and the role of significant life transitions in altering the pattern of alcohol use presented previously by these youths.

Background: Traffic accidents are the second leading cause of death among adolescents and young adults in Chile. However, few studies have examined this behavior among this age group. Parental practices have a great influence on risk behaviors in adolescents, such as substance use, sexuality and violence, among others. Specifically, we propose that these practices will influence pedestrian risk behaviors among adolescents., Aim: To study the role of parental practices such as mother and father support, and behavioral control (monitoring and presence of rules) in pedestrian risk behaviors of teenagers., Material and Methods: A sample of 470 adolescents attending schools in the Metropolitan Region of Santiago, Chile were studied. They answered a self-administered questionnaire in which they were asked about parental practices and pedestrian risk behaviors. Analyses were performed using descriptive and inferential statistics, using multiple regression., Results: Paternal support and the presence of rules were protective factors for pedestrian risky behaviors. However, maternal support or monitoring did not influence these behaviors., Conclusions: Parental practices influence pedestrian behaviors of teenagers. The study provides further evidence for the importance of these practices in the development of behavioral self-regulation.
