Young adult substance abuse down 42 percent among PROSPER program participants

Children who participated in the PROSPER (PROmoting School-community-university Partnerships to Enhance Resilience) program over seven years ago showed lower rates of substance abuse after high school graduation, according to a new study conducted by researchers from Pennsylvania State and Iowa State Universities and published in a recent issue of Psychological Medicine.

PROSPER, a community-based preventive intervention delivery system, is offered to young adolescents during middle school—a pivotal period when exposure to and uptake of substances and other risky behavior begins.

In this latest study, researchers found a 41 percent reduction in within a group of more than 1,900 19-year-olds, randomly selected and followed after the spring of 12th grade.

"We already knew that the PROSPER program helped reduce and conduct problems during middle and high school, but now we see its impact extending beyond school into early adulthood," said Mark Feinberg, PROSPER's Pennsylvania principal investigator and research professor with the Edna Bennett Pierce Prevention Research Center at Penn State. "This is important news given that the prevalence of illicit drug use is highest among young people between the ages of 19 and 22."

Research shows that the earlier a teen starts using substances, the more likely the teen is to develop dependence or serious substance-use related problems down the road. Substance use can lead to addiction, mental disorders, disease, injury and death.

"Prevention programs like PROSPER can help delay the experimentation with at an early age," said Janet Welsh, coordinator for the Pennsylvania PROSPER team. "And, now, with this latest research, we see more positive outcomes for these kids as they enter adulthood, which hopefully will carry over into more positive long-term outcomes in terms of parenting and career success."

Substance misuse has both serious individual and societal consequences. According to the National Institute on Drug Abuse, the costs of tobacco, alcohol and use to the U.S. economy is estimated at more than $700 billion annually.

"These findings have very significant implications for the future of our nation's public health. If implemented broadly across communities, the PROSPER system has the potential to reduce drug and alcohol addiction over the long term and benefit everyone," said Feinberg.

The PROSPER model is designed to reduce risky youth behaviors, enhance positive youth development and strengthen families. PROSPER consists of a partnership between university Cooperative Extension educators and school, agency and parent representatives in a community. This partnership serves as an "operating system" for communities to install and sustain evidence-based, substance-use prevention programs for middle school youth and families.

The latest report is based on long-term follow-up of the sample in the PROSPER research trial, which began in 2001. The research is a randomized, controlled study of the effectiveness of the PROSPER model across 28 public schools in Pennsylvania and Iowa. The model includes a family-focused intervention in the sixth grade and a -based intervention in the seventh grade.
