The Community Youth Development Study is an experimental test of the Communities That Care (CTC) prevention planning system. It is designed to find out if communities that use the CTC system can improve the public health by reducing rates of adolescent drug use, delinquency, violence, and risky sexual behavior when compared to communities that do not use this approach.

Primary Outcome Measures:
  • Youth Substance Use, Delinquency, and Risky Sexual Behavior [ Time Frame: Baseline through eight-year follow-up ] [ Designated as safety issue: No ]
    Self-report longitudinal surveys of the Class of 2011 conducted annually starting in 5th grade (2004) and continuing through 2012 (one year post-HS), and cross-sectional anonymous surveys of 6th, 8th, 10th, and 12th grade students in all participating communities conducted every 2 years from 2002 through 2012 will be used to assess the impact of the intervention on students' behaviors.

Secondary Outcome Measures:
  • Youth risk and protective factors [ Time Frame: Baseline through eight-year follow up ] [ Designated as safety issue: No ]
    Self-report longitudinal surveys of the Class of 2011 conducted annually starting in 5th grade (2004) and continuing through 2012 (one year post-HS), and cross-sectional anonymous surveys of 6th, 8th, 10th, and 12th grade students in all participating communities conducted every 2 years from 2002 through 2012 will be used to assess the impact of the intervention on the risk and protective factors experienced by students.

  • Community prevention systems transformation [ Time Frame: Baseline through eight-year follow up ] [ Designated as safety issue: No ]
    Telephone interviews with community leaders and prevention services providers conducted in 2001-02, 2004-05, 2007-08, 2009-10, and 2011-12 will be used to assess intervention effects on community prevention services planning, coordination, use of data for needs assessment and program performance, and monitoring, and on the numbers and scope of tested and effective prevention programs, policies and curricula provided to middle and high school students in participating communities.

Estimated Enrollment: 53000
Study Start Date: October 2003
Estimated Study Completion Date: December 2012
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: No intervention
Communities in the no intervention arm received no intervention from the project and continued to implement prevention services as usual.
Experimental: Communities That Care Intervention
Communities randomly assigned to the experimental condition received 5 years of training and technical assistance (from 2003 to 2008) to implement the Communities That Care (CTC) prevention system in their communities. They also received 5 years of funding to support a full-time community coordinator and 4 years of seed money to implement tested and effective prevention programs selected as a result of their CTC process.
Behavioral: Communities That Care
The Communities That Care (CTC) system provides communities training and ongoing technical assistance in a structured process for conducting prevention needs assessments using epidemiological data on levels of risk and protective factors for adolescent problem behaviors, selection of tested and effective preventive interventions shown to address community-prioritized factors, implementation of these interventions with fidelity, and evaluation of the community's progress toward its goals. The CTC system is designed to produce a plan for prevention services that is tailored to the needs of each community. CTC is installed in five phases through a manualized series of training events designed to build the capacity of communities to install and sustain the system over time.

Detailed Description:

Preventing alcohol, tobacco, and other drug use; delinquency; violence; and health-risking sexual behavior among adolescents is a national priority. While advances in prevention science over the past two decades have produced a growing list of tested and effective programs and policies for preventing these behaviors, widespread dissemination and high-quality implementation of these effective programs and policies in communities has not been achieved. The development and testing of approaches for translating prevention research findings into effective community prevention service systems is important to achieve reductions in the prevalence of adolescent health and behavior problems.

The Community Youth Development Study (CYDS) is a randomized community-level test of the effects of Communities That Care (CTC) on prevention systems and adolescent behavior. The CTC system provides tools, training, and technical assistance that assist communities to use local epidemiologic data on risk and protective factors to identify and prioritize specific elevated risks and depressed protective factors and then to choose and implement tested, effective preventive interventions that have affected the prioritized risk and protective factors. The CTC system is hypothesized first to produce effects on key characteristics of community prevention service systems, which, in turn, produce subsequent effects on community levels of risk and protective factors in 2 to 5 years, and effects on youth problem behaviors in 3 to 10 years.

The current study assesses the effects of installation and implementation of CTC during the time period in which the CTC system is expected to produce its strongest effects on youth problem behaviors; that is, from 5 to 9 years following its initial installation. During this study, youths in the longitudinal panel followed from Grades 5 through 9 in the initial study will pass through high school, the developmental period of greatest risk for delinquent and violent behavior, and a period of greatly increasing substance use and problems related to substance use. The study will assess the long-term effects of CTC on community prevention service systems and on adolescent risk and problem behaviors for 4 years following the end of study-provided resources that supported the implementation of CTC in the 12 intervention communities during the initial efficacy trial.
