The effect of neighborhood-based community organizing: results from the Seattle Minority Youth Health Project.

OBJECTIVE: To evaluate the effect of a community mobilization and youth development strategy to prevent drug abuse, violence, and risky sexual activity. DATA SOURCES/STUDY SETTING: Primary surveys of youth, parents, and key neighborhood leaders were carried out at baseline (1994) and at the end of the intervention period (1997). The study took place in four intervention and six control neighborhoods in Seattle. STUDY DESIGN: The study was designed as a randomized controlled trial with neighborhood as the unit of randomization. The intervention consisted of a paid community organizer in each neighborhood who recruited a group of residents to serve as a community action board. Key variables included perceptions of neighborhood mobilization by youth, parents, and key neighborhood leaders. DATA COLLECTION/EXTRACTION METHODS: Youth surveys were self-administered during school hours. Parent and neighborhood leader surveys were conducted over the phone by trained interviewers. PRINCIPAL FINDINGS: Survey results showed that mobilization increased to the same degree in both intervention and control neighborhoods with no evidence of an overall intervention effect. There did appear to be a relative increase in mobilization in the neighborhood with the highest level of intervention activity. CONCLUSION: This randomized study failed to demonstrate a measurable effect for a community mobilization intervention. It is uncertain whether the negative finding was because of a lack of strength of the interventions or problems detecting intervention effects using individual-level closed-end surveys.

Effectiveness of a violence prevention curriculum among children in elementary school. A randomized controlled trial.

OBJECTIVE: To determine if a commonly used violence prevention curriculum, Second Step: A Violence Prevention Curriculum, leads to a reduction in aggressive behavior and an increase in prosocial behavior among elementary school students. DESIGN: Randomized controlled trial. SETTING: Urban and suburban elementary schools in the state of Washington. PARTICIPANTS: Six matched pairs of schools with 790 second-grade and third-grade students. The students were 53% male and 79% white. INTERVENTION: The curriculum uses 30 specific lessons to teach social skills related to anger management, impulse control, and empathy. MAIN OUTCOME MEASURES: Aggressive and prosocial behavior changes were measured 2 weeks and 6 months after participation in the curriculum by parent and teacher reports (Achenbach Child Behavior Checklist and Teacher Report Form, the School Social Behavior Scale, and the Parent-Child Rating Scale) and by observation of a random subsample of 588 students in the classroom and playground/cafeteria settings. RESULTS: After adjusting for sex, age, socioeconomic status, race, academic performance, household size, and class size, change scores did not differ significantly between the intervention and control schools for any of the parent-reported or teacher-reported behavior scales. However, the behavior observations did reveal an overall decrease 2 weeks after the curriculum in physical aggression (P=.03) and an increase in neutral/prosocial behavior (P=.04) in the intervention group compared with the control group. Most effects persisted 6 months later. CONCLUSIONS: The Second Step violence prevention curriculum appears to lead to a moderate observed decrease in physically aggressive behavior and an increase in neutral and prosocial behavior in school.

Early school dropout: configurations and determinants.

This longitudinal study examined behavioral, cognitive, and demographic factors associated with early school dropout. Follow-up assessments were completed on a sample of girls (n = 248) and boys (n = 227) who had first been seen when they were in the seventh grade. School status was determined for all living subjects; 99% of them were interviewed individually in the fifth annual test wave. Overall, 14% of the group had dropped out of school prior to completing grade 11. The clusters of males and females most vulnerable to early school dropout were characterized in grade 7 by high levels of aggressiveness and low levels of academic performance (82% early dropout in males; 47% early dropout in females). In seventh grade, subjects who subsequently dropped out tended to affiliate with persons who were also at risk for dropout. Socioeconomic status, race, and early parenthood were also associated with school dropout. The primary outcomes were supported by convergent variable-oriented and person-oriented analyses. Some developmental dynamics of the phenomena are discussed.
