Iowa Case Management for Rural Drug Abuse

OBJECTIVE: The purpose of this research was to evaluate the effectiveness of a comprehensive, strengths-based model of case management for clients in drug abuse treatment. METHOD: 503 volunteers from residential or intensive outpatient treatment were randomly assigned to one of three conditions of Iowa Case Management (ICM) plus treatment as usual (TAU), or to a fourth condition of TAU only. All were assessed at intake and followed at 3, 6, and 12 months. RESULTS: Clients in all four conditions significantly decreased substance use by 3 months after intake and maintained most gains over time. However, the addition of ICM to TAU did not improve substance use outcomes. CONCLUSION: Overall, the addition of case management did not significantly improve drug treatment as hypothesized by both researchers and clinicians. Some results were mixed, possibly due to the heterogeneous sample, wide range of case management activities, or difficulty retaining participants over time.     

Peer Groups, Social Identity, and Children's Bullying Behavior

Drawing on social identity theory, this study explored the impact of the peer group on childhood bullying. Participants were 351 students, aged 8 to 13 years. Involvement in bullying, friendship group membership, norms of particular groups, and intra-group positions (prototypical vs. peripheral) were determined using peer reports. Results revealed within-group similarities in bullying behaviors. In addition, bullying was found to be greater when it was endorsed by group norms and when children were prototypical vs. peripheral members of bullying groups. The implications of the findings for the conceptualization of childhood bullying are discussed.     

Exploring Neighborhood Effects on Health and Life Satisfaction: Disentangling Neighborhood Racial Density and Neighborhood Income

This study examines the independent and synergistic influences of neighborhood racial density and neighborhood income on several indicators of health status and life satisfaction in a sample of 311 adult African Americans living in New York City. This is made possible by the two-stage sampling procedure that was used in the collection of the data, ensuring that respondents?? neighborhoods vary on both racial density and income. Findings from a series of OLS regression models that adjust standard errors to account for the non-independence of observations demonstrate that neighborhood income moderates the relationship between racial density and health and life satisfaction. When neighborhood income is low, high neighborhood racial density is detrimental for health and life satisfaction. However, when neighborhood income is high, neighborhood racial density is protective for health and life satisfaction. These results indicate that the role of neighborhood income needs to be considered when examining the relationship between neighborhood racial density, health, and life satisfaction. Moreover, these findings may provide insight for understanding the past conflicting results.     

Digital Gaming and Pediatric Obesity: At the Intersection of Science and Social Policy

Children and adolescents in developed countries are heavily immersed in digital media, creating an inexpensive, far-reaching marketing opportunity for the food industry and the gaming industry. However, exposure to nonnutritious food and beverage advertisements combined with the use of stationary media create a conflict between entertainment and public health. Using the popular digital gaming platforms advergames (online games that market branded products) and exergames (video games that involves gross motor activity for play) as exemplars, the following article provides an analysis of the negative and positive health impacts of digital gaming as they relate specifically to overweight and obesity outcomes for children and adolescents. Theoretical explanations including the food marketing defense model, persuasion knowledge model, and social cognitive theory are used to explain the influence of gaming on young players' health. Throughout the article, we discuss the role of public policy to encourage the development and use of health-promoting digital games as an innovative, effective tool to combat the pediatric obesity crisis.     

On a cramér-von mises type statistic for testing bivariate independence

A Cramér-von Mises type statistic for testing bivariate independence, proposed by Hoeffding (1948) and by Blum, Kiefer, and Rosenblatt (1961), is examined in greater detail. The statistic is decomposed into components in the manner of Durbin and Knott (1972), and the components are shown to be related to linear rank statistics. Asymptotic power properties of the Hoeffding statistic and its components in testing for independence with bivariate normal random observations are described; a Monte Carlo study comparing these statistics with other nonparametric statistics for bivariate independence is also reported.
