This article tested a model, informed by the knowledge gap hypothesis, to predict information seeking about cancer immediately following news about the diagnosis or death from cancer of a national celebrity. I identified five celebrity news events and examined their impact using data from the 2005 Health Information National Trends Survey. News coverage about celebrity news events was more likely to promote information seeking among people with greater education than among those with less education. These differences were explained, at least in part, by the fact that highly educated people had greater health knowledge and community involvement than less‐educated people. These factors may contribute to widening socioeconomic gaps in prevention behaviors. I suggest strategies to address these gaps. 相似文献

The goal of this research is to examine the trajectory of school bonding over the middle school period and how factors such as gender, substance use, antisocial peers, delinquent behavior, and academic achievement affect this developmental process. Data from 4 waves of measurement of 2,902 adolescents are analyzed using hierarchical growth curve modeling. Results suggest that school bonding decreases in a non-linear fashion from Grade 6-8. However, school bonding development varies based on inter-individual differences. Boys have lower initial levels and greater decreases in school bonding than girls. Student deviant behavior, having antisocial peers, and low academic achievement are associated with lower levels of school bonding at Grade 6. Low grades and an increase in substance use are associated with a steeper decrease of school bonding over time. Increases in substance use and being male are also associated with a curvilinear pattern of school bonding. Implications for interventions are discussed. 相似文献
