The use of complexity-based evaluation methods remains relatively underexplored in the field of evaluation. While increasingly employed to assess complex interventions, Contribution Analysis (CA) continues to suffer from a lack of operationalization. In this article, we propose enhancing the implementation of CA by leveraging Participatory Systems…

Schools are a critical setting for improving child nutrition and food security and preventing obesity in the United States. The U.S. Department of Agriculture mandates that the Supplemental Nutrition Assistance Program--Education, known as CalFresh Healthy Living (CFHL) in California, implements obesity prevention efforts that utilize…

Impact evaluation and measurement are highly complex and can pose challenges for both social impact providers and funders. Measuring the impact of social interventions requires the continuous exploration and improvement of evaluation approaches and tools. This article explores the available evidence on meta-evaluation--the "evaluation of…

Program evaluations that lack experimental design often fail to produce evidence of impact because there is no available control group. Theory-based evaluations can generate evidence of a program's causal effects if evaluators collect evidence along the theorized causal chain and identify possible competing causes. However, few methods are…

Intervention programs are open systems that must withstand the disturbances of the environments in which they are implemented if they are to thrive. Stakeholders can benefit from proactive insights related to potential program malfunction or failure. Evaluators have not developed approaches to serve this preventive function. This study proposes…

Evaluation is defined by its central task of valuing--the process and product of judging the merit, worth, or significance of a policy or program. However, there are no clear-cut ways to consider values and render value judgments in evaluation practice. There remains contention in the evaluation field about whether and how to make value judgments.…

This article reports findings from a research program exploring the role of mediation in an "adaptive learning" process through study of developmental evaluation (DE). Our study focuses on how mediators might influence the relationships between components of a social learning system and the implications for adaptive learning.…

The terms "outcome" and "impact" are ubiquitous in evaluation discourse. However, there are many competing definitions that lack clarity and consistency and sometimes represent fundamentally different meanings. This leads to profound confusion, undermines efforts to improve learning and accountability, and represents a…

Since April 2013, the Eleanor Chelimsky Forum has served as the centerpiece of the Eastern Evaluation Research Society's (EERS) annual conference. Eleanor Chelimsky (2012), a highly esteemed pioneer in the evaluation field, inspired the Forum in her 2012 plenary address (subsequently published in "American Journal of Evaluation"…

HIV continues to significantly impact the health of communities, particularly affecting racially and ethnically diverse men who have sex with men and transgender women. In response, health departments often fund a number of community organizations to provide each of these subgroups with comprehensive and culturally responsive services. To this…

In experimental evaluations of health and social programs, the role of dosage is rarely explored because researchers cannot usually randomize individuals to experience varying dosage levels. Instead, such evaluations reveal the average effects of exposure to an intervention, although program exposure may vary widely. This article compares three…

This article presents the principles and findings of developing a new participatory assessment of development (PADev) evaluation approach that was codesigned with Dutch nongovernmental organizations (NGOs) and northern and southern research institutes over a period of 4 years in the context of rural development in Ghana and Burkina Faso. Although…

This article describes the development and use of a rapid evaluation approach to meet program accountability and learning requirements in a research for development program operating in five developing countries. The method identifies clusters of outcomes, both expected and unexpected, happening within areas of change. In a workshop, change agents…

The need for evaluation capacity building (ECB) in military psychological health is apparent in light of the proliferation of newly developed, yet untested programs coupled with the lack of internal evaluation expertise. This study addresses these deficiencies by utilizing Preskill and Boyle's multidisciplinary ECB model within a post-traumatic…

This article presents discussion and recommendations on approaches to retrospectively evaluating development interventions in the long term through a systems lens. It is based on experiences from the implementation of an 18-month study to investigate the impact of development interventions on economic and social change over a 40-year period in the…
