William Bunker Hansen (born November 15, 1949) is a researcher in the field of prevention science. He was a charter member and a vice president of the Society for Prevention Research. In 1993 he founded Tanglewood Research. He has authored over 40 versions of alcohol, tobacco, and other substance abuse prevention programs, most notably the All Stars (Prevention) series of prevention programs. [1]
Hansen's notable contribution to science has been the development of school-based prevention programs. His program development approach focuses on longitudinal statistical mediators and devising strategies for altering normal developmental processes. [2] Projects on which he played the role of primary intervention developer include the Houston Smoking Prevention Project (1974-1978), Project SMART (1980-1985), the Tobacco and Alcohol Prevention Project (1981-1986), the Adolescent Alcohol Prevention Trial (1984-1992), the Midwestern Prevention Project (1985-1992), and projects related to the development of All Stars (Prevention) (1996–present). In recognition of these contributions, the Society for Prevention Research awarded him the Prevention Research to Practice Award in 2001.
Prevention science relies on several basic assumptions about the relations between mediators and behavioral outcomes. Hansen proposed two laws that undergird prevention program effectiveness: [3]
He was funded in 1995 to develop standardized measurement modules for evaluating prevention programs. [4] He chaired a SAMHSA committee to develop standardized survey tools for use by prevention scientists. His own research resulted in the development of Evaluation Lizard, which is a system for collecting and evaluating pretest and posttest surveys. [5] This research was supplemented in 2008 to develop a method for using synthetic comparators. [6] [7] He is currently directing the development of Virtual Controls, [8] a strategy to evaluate disseminated prevention programs when randomization is not possible and recruitment of comparison sites is challenging [9] [10]
Hansen was among the first drug prevention researchers to acknowledge that quality of implementation (often referred to as fidelity) was a key moderator of the success of intervention efforts. In the past decade, he and his colleagues have developed systematic strategies for assessing quality of delivery, including a rubric for assessing adaptations that teachers make when delivering interventions in real world settings. Fidelity assessment tools have been built into Evaluation Lizard and Virtual Controls as an option available to users.
Prior to the development of interventions, the field needs to understand normative development of drug use and other closely intertwined problem behaviors. While this has not been a primary focus of his research, Hehas nonetheless published several empirical studies that have directly influenced the development of the prevention programs. Early studies were embedded in prevention program evaluation research projects. Later research was funded as part of a study to look at predictors of the onset of drug in grades 6th-12th grades.

Drug Abuse Resistance Education is an education program that seeks to prevent use of controlled drugs, membership in gangs, and violent behavior. It was founded in Los Angeles in 1983 as a joint initiative of then-LAPD chief Daryl Gates and the Los Angeles Unified School District as a demand-side drug control strategy of the American War on Drugs. The program's mascot is Daren the Lion.
Behavior change, in context of public health, refers to efforts put in place to change people's personal habits and attitudes, to prevent disease. Behavior change in public health can take place at several levels and is known as social and behavior change (SBC). More and more, efforts focus on prevention of disease to save healthcare care costs. This is particularly important in low and middle income countries, where supply side health interventions have come under increased scrutiny because of the cost.
The social norms approach, or social norms marketing, is an environmental strategy gaining ground in health campaigns. While conducting research in the mid-1980s, two researchers, H.W. Perkins and A.D. Berkowitz, reported that students at a small U.S. college held exaggerated beliefs about the normal frequency and consumption habits of other students with regard to alcohol. These inflated perceptions have been found in many educational institutions, with varying populations and locations. Despite the fact that college drinking is at elevated levels, the perceived amount almost always exceeds actual behavior. The social norms approach has shown signs of countering misperceptions, however research on changes in behavior resulting from changed perceptions varies between mixed to conclusively nonexistent.
Brief intervention can often be referred to as screening and brief intervention (SBI) or, in England, identification and brief advice (IBA). Brief interventions are a technique used to initiate change for an unhealthy or risky behaviour such as smoking, lack of exercise or alcohol misuse. This page primarily describes brief interventions as applied to alcohol. As an alcohol intervention it is typically targeted to non-dependent drinkers, or drinkers who might be experiencing problems but are not seeking treatment. It is an approach which aims to prevent the acceleration or impact of alcohol problems, and/or to reduce alcohol consumption. It can be carried out in a range of settings such as in primary care, emergency or other hospital departments, criminal justice settings, workplaces, online, university/college settings, and other settings.
Workplace wellness is any workplace health promotion activity or organizational policy designed to support healthy behavior in the workplace and to improve health outcomes. Known as 'corporate wellbeing' outside the US, workplace wellness often comprises activities such as health education, medical screenings, weight management programs, on-site fitness programs or facilities.

Communities That Care (CTC) is a program of the Center for Substance Abuse Prevention (CSAP) in the office of the United States Government's Substance Abuse and Mental Health Services Administration (SAMHSA). CTC is a coalition-based prevention operating system that uses a public health approach to prevent youth problem behaviors such as violence, delinquency, school drop out and substance abuse. Using strategic consultation, training, and research-based tools, CTC is designed to help community stakeholders and decision makers understand and apply information about risk and protective factors, and programs that are proven to make a difference in promoting healthy youth development, in order to most effectively address the specific issues facing their community's youth.
Health communication is the study and practice of communicating promotional health information, such as in public health campaigns, health education, and between doctor and patient. The purpose of disseminating health information is to influence personal health choices by improving health literacy. Health communication is a unique niche in healthcare that allows professionals to use communication strategies to inform and influence decisions and actions of the public to improve health.
The PRECEDE–PROCEED model is a cost–benefit evaluation framework proposed in 1974 by Lawrence W. Green that can help health program planners, policy makers and other evaluators, analyze situations and design health programs efficiently. It provides a comprehensive structure for assessing health and quality of life needs, and for designing, implementing and evaluating health promotion and other public health programs to meet those needs. One purpose and guiding principle of the PRECEDE–PROCEED model is to direct initial attention to outcomes, rather than inputs. It guides planners through a process that starts with desired outcomes and then works backwards in the causal chain to identify a mix of strategies for achieving those objectives. A fundamental assumption of the model is the active participation of its intended audience — that is, that the participants ("consumers") will take an active part in defining their own problems, establishing their goals and developing their solutions.
Prevention science is the application of a scientific methodology that seeks to prevent or moderate major human dysfunctions before they occur. Regardless of the type of issue on hand, the factors that lead to the problem must be identified and addressed. Prevention research is thus focused primarily on the systematic study of these potential precursors of dysfunction, also known as risk factors; as well as components or circumstances that reduces the probability of problem development in the presence of risk, also known as protective factors. Preventive interventions aim to counteract risk factors and reinforce protective factors in order to disrupt processes or situations that give rise to human or social dysfunction.
The FRIENDS Programs are a series of Resilience programs developed by Professor Paula Barrett. The programs aim to increase social and emotional skills, promote resilience, and preventing anxiety and depression across the lifespan. As a prevention protocol, FRIENDS has been noted as “one of the most robustly-supported programmes for internalising disorders,” with “a number of large-scale type 1 randomised control trials worldwide” demonstrating its effectiveness ( ). The FRIENDS programs are acknowledged by the World Health Organization as effective evidence based prevention programs.

Risky sexual behavior is the description of the activity that will increase the probability that a person engaging in sexual activity with another person infected with a sexually transmitted infection will be infected or become pregnant, or make a partner pregnant. It can mean two similar things: the behavior itself, the description of the partner's behavior. The behavior could be unprotected vaginal, oral, or anal intercourse. The partner could be a nonexclusive partner, HIV-positive, or an person who injects substances. Substance use is associated with risky sexual behaviors.
