Huey-tsyh Chen is a Taiwanese American sociologist and scholar of program evaluation. He is Professor in the Department of Public Health and Director of the Center for Evaluation and Applied Research at Mercer University. [1]
Huey-tsyh Chen was born in Taiwan. He received his PhD in sociology from the University of Massachusetts, supervised by Peter Rossi. [2] He has worked at the University of Akron and the University of Alabama at Birmingham. [3] He also served as branch chief and senior evaluation scientist at the U.S. Centers for Disease Control and Prevention (CDC), where he led the development of a national evaluation system for evaluating CDC-funded HIV prevention programs. [4]
Chen is best known for his contributions to the theory and methodology of program evaluation, particularly theory-driven evaluation (often seen as a type of theory-based evaluation [5] ), about which he wrote the first comprehensive book. [6] [7]
In 1993 Chen was the recipient of the Paul F. Lazarsfeld Award for contributions to Evaluation Theory from the American Evaluation Association. [8]
Theory-driven evaluation begins with the premise that social programs are attempts to intervene on some aspect of society to solve social problems and do so using a program theory, though one that is "frequently implicit or unsystematic". [9] The approach was developed in response to "black-box" evaluation, which tended to focus on research methods rather than attempting to understand the mechanisms through which a program might work. Key reasons for this include learning from null results and to improve the implementation of successful programs. [10] Chen distinguishes between normative theory, specifying, for instance, the goals of the program, and causal theory, which specifies how the program is thought to work, and argues that both are required for evaluation. [11] Further clues on what kind of theory is intended come from a paper Chen authored with Peter Rossi: [12]
the kind of theory we have in mind is not the global conceptual schemes of the grand theorists, but much more prosaic theories that are concerned with how human organizations work and how social problems are generated. It advances evaluation practice very little to adopt one or another of current global theories in attacking, say, the problem of juvenile delinquency, but it does help a great deal to understand the authority structure in schools and the mechanisms of peer group influence and parental discipline in designing and evaluating a program that is supposed to reduce disciplinary problems in schools. [...T]he theory-driven perspective is closer to what econometricians call "model specification" than are more complicated and more abstract and general theories.
It has been thought that theory-driven evaluation focussed on statistical approaches such as path analysis. [13] However, Chen has also made case for the importance of qualitative methods, particularly when developing program theories. [14]
In common usage, evaluation is a systematic determination and assessment of a subject's merit, worth and significance, using criteria governed by a set of standards. It can assist an organization, program, design, project or any other intervention or initiative to assess any aim, realisable concept/proposal, or any alternative, to help in decision-making; or to generate the degree of achievement or value in regard to the aim and objectives and results of any such action that has been completed.
The AIDS epidemic, caused by HIV, found its way to the United States between the 1970s and 1980s, but was first noticed after doctors discovered clusters of Kaposi's sarcoma and pneumocystis pneumonia in homosexual men in Los Angeles, New York City, and San Francisco in 1981. Treatment of HIV/AIDS is primarily via the use of multiple antiretroviral drugs, and education programs to help people avoid infection.
Program evaluation is a systematic method for collecting, analyzing, and using information to answer questions about projects, policies and programs, particularly about their effectiveness and efficiency.
Policy analysis or public policy analysis is a technique used in the public administration sub-field of political science to enable civil servants, nonprofit organizations, and others to examine and evaluate the available options to implement the goals of laws and elected officials. People who regularly use policy analysis skills and techniques on the job, particularly those who use it as a major part of their job duties are generally known by the title policy analyst. The process is also used in the administration of large organizations with complex policies. It has been defined as the process of "determining which of various policies will achieve a given set of goals in light of the relations between the policies and the goals."
Adaptive management, also known as adaptive resource management or adaptive environmental assessment and management, is a structured, iterative process of robust decision making in the face of uncertainty, with an aim to reducing uncertainty over time via system monitoring. In this way, decision making simultaneously meets one or more resource management objectives and, either passively or actively, accrues information needed to improve future management. Adaptive management is a tool which should be used not only to change a system, but also to learn about the system. Because adaptive management is based on a learning process, it improves long-run management outcomes. The challenge in using the adaptive management approach lies in finding the correct balance between gaining knowledge to improve management in the future and achieving the best short-term outcome based on current knowledge. This approach has more recently been employed in implementing international development programs.
Social marketing is a marketing approach which focuses on influencing behavior with the primary goal of achieving "common good." It utilizes the elements of commercial marketing and applies them to social concepts. However, to see social marketing as only the use of standard commercial marketing practices to achieve non-commercial goals is an oversimplified view. Social marketing has existed for some time, but has only started becoming a common term in recent decades. It was originally done using newspapers and billboards and has adapted to the modern world in many of the same ways commercial marketing has. The most common use of social marketing in today's society is through social media.
Positive youth development (PYD) programs are designed to optimize youth developmental progress. This is sought through a positivistic approach that emphasizes the inherent potential, strengths, and capabilities youth hold. PYD differs from other approaches within youth development work in that it rejects an emphasis on trying to correct what is considered wrong with children's behavior or development, renouncing a problem-oriented lens. Instead, it seeks to cultivate various personal assets and external contexts known to be important to human development.
Participatory action research (PAR) is an approach to action research emphasizing participation and action by members of communities affected by that research. It seeks to understand the world by trying to change it, collaboratively and following reflection. PAR emphasizes collective inquiry and experimentation grounded in experience and social history. Within a PAR process, "communities of inquiry and action evolve and address questions and issues that are significant for those who participate as co-researchers". PAR contrasts with mainstream research methods, which emphasize controlled experimentation, statistical analysis, and reproducibility of findings.
Health promotion is, as stated in the 1986 World Health Organization (WHO) Ottawa Charter for Health Promotion, the "process of enabling people to increase control over, and to improve their health."
Social cognitive theory (SCT), used in psychology, education, and communication, holds that portions of an individual's knowledge acquisition can be directly related to observing others within the context of social interactions, experiences, and outside media influences. This theory was advanced by Albert Bandura as an extension of his social learning theory. The theory states that when people observe a model performing a behavior and the consequences of that behavior, they remember the sequence of events and use this information to guide subsequent behaviors. Observing a model can also prompt the viewer to engage in behavior they already learned. Depending on whether people are rewarded or punished for their behavior and the outcome of the behavior, the observer may choose to replicate behavior modeled. Media provides models for a vast array of people in many different environmental settings.
Logic models are hypothesized descriptions of the chain of causes and effects leading to an outcome of interest. While they can be in a narrative form, logic model usually take form in a graphical depiction of the "if-then" (causal) relationships between the various elements leading to the outcome. However, the logic model is more than the graphical depiction: it is also the theories, scientific evidences, assumptions and beliefs that support it and the various processes behind it.

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.
Theory of Change (ToC) is a methodology or a criterion for planning, participation, adaptive management, and evaluation that is used in companies, philanthropy, not-for-profit, international development, research, and government sectors to promote social change. A Theory of Change of a social program defines its long-term goals and then maps backward to identify necessary preconditions.
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.
Empowerment evaluation (EE) is an evaluation approach designed to help communities monitor and evaluate their own performance. It is used in comprehensive community initiatives as well as small-scale settings and is designed to help groups accomplish their goals. According to David Fetterman, "Empowerment evaluation is the use of evaluation concepts, techniques, and findings to foster improvement and self-determination". An expanded definition is: "Empowerment evaluation is an evaluation approach that aims to increase the likelihood that programs will achieve results by increasing the capacity of program stakeholders to plan, implement, and evaluate their own programs."
Intervention mapping is a protocol for developing theory-based and evidence-based health promotion programs. Intervention Mapping describes the process of health promotion program planning in six steps:
Robert L. Selman is an American-born educational psychologist and perspective-taking theorist who specializes in adolescent social development. He is currently a professor of Education and Human Development at the Harvard Graduate School of Education, and a professor of psychology in Medicine at Harvard University. He is also known as the author of the 1980s G.I. Joe public service announcements.
A causal map can be defined as a network consisting of links or arcs between nodes or factors, such that a link between C and E means, in some sense, that someone believes or claims C has or had some causal influence on E.
Theory-driven evaluation is an umbrella term for any approach to program evaluation that develops a theory of change and uses it to design, implement, analyze, and interpret findings from an evaluation. More specifically, an evaluation is theory-driven if it:
