Brief Summary:
The Community Youth Development Study is an experimental test of the Communities That Care (CTC) prevention planning system. It has been designed to find out if communities that were trained to use the CTC system improved public health by reducing rates of adolescent drug use, delinquency, violence, and risky sexual behavior when compared to communities that did not use this approach. The primary purpose of the current continuation study is to investigate whether CTC has long-term effects on substance use, antisocial behavior, and violence, as well as secondary effects on educational attainment, mental health, and sexual risk behavior in young adults at ages 26 and 28. The continuation study also examines (a) how the interaction of social, normative, and legal marijuana contexts creates variation in the permissiveness of individuals' marijuana environments from late childhood to young adulthood and (b) whether, when, and for whom permissive marijuana environments increase marijuana and ATOD use and misuse from age 11 to 28 and interfere with the adoption of adult roles.

Arm Intervention/treatment
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.

Primary Outcome Measures :
  1. Targeted risk and protective factors, substance use, delinquency, violence [ Time Frame: Baseline through thirteen-year follow-up (age 23) ]
    Surveys of the panel starting in 5th grade (2004) and continuing in grades 6-10, grade 12, and at ages 19, 21, and 23 are used to assess the impact of the intervention on risk and protective factors targeted by communities, substance use, delinquency, and violence. Cross-sectional surveys of all youth in grades 6, 8, 10, and 12 in all participating communities, conducted every 2 years from 2002 through 2012, are also used to assess the impact of the intervention on these primary outcomes.

  2. CTC coalition functioning, prevention system transformation, evidence-based program (EBP) implementation [ Time Frame: Baseline through eight-year follow-up (age 18) ]
    Structured telephone interviews with key community leaders, CTC coalition members, and prevention services providers (Community Key Informant Survey, Coalition Board Interview, Community Resource Documentation Survey) conducted in 2001-02, 2004-05, 2007-08, 2009-10, and 2011-12 are used to assess intervention effects on CTC coalition functioning, prevention system transformation, and evidence-based prevention program implementation.

Secondary Outcome Measures :
  1. Substance use disorder, depression and generalized anxiety disorder, sexual risk behavior [ Time Frame: Nine- through thirteen-year follow-up ]
    Secondary outcomes salient in late adolescence and young adulthood were added to the self-report longitudinal survey beginning at the nine-year follow-up (age 19).

Individual Participant Data (IPD) Sharing Statement:
Plan to Share IPD: Yes
Plan Description: We support the goal of making datasets available to researchers in a timely manner to expedite translation of research results into knowledge, products, and procedures to improve human health. With these goals in mind, we have entered into data-sharing collaborations many times with outside researchers. To ensure that the use of these data stay within the legal and ethical constraints of the consent agreement under which they were collected, we have developed a Fair Use Agreement, available upon request, that is signed by the Principal Investigator, Dr. Kuklinski, and by the collaborating researcher when agreement has been reached to share study data. As part of the Fair Use Agreement, we ask researchers to abide by the same Data and Safety Monitoring Plan (DSMP) that we adhere to. We will continue to share data with other researchers who meet the terms of our Fair Use Agreement (and DSMP) and share our strong commitment to protection of the rights and privacy of study participants.
