  • 1 Applying a Deviance Framework to Understand How Place Shapes
    Applying a Deviance Framework to Understand How Place Shapes Modern Contraceptive Use in Sub-Saharan Africa Tamar Goldenberg 1, 2 and Rob Stephenson,2, 3 1Department of Health Behavior and Health Education, School of Public Health, University of Michigan, Ann Arbor, MI, 48109 2Center for Sexuality & Health Disparities, University of Michigan, Ann Arbor, 48109 3Department of Health Behavior and Biological Sciences, School of Nursing, University of Michigan, Ann Arbor, MI, 48109 1 ABSTRACT: Increasing modern contraception use is important for improving maternal and child health and achieving economic growth and development goals. However, high unmet need for modern contraception in Sub-Saharan Africa warrants new understandings of the drivers of modern contraceptive use. Using data from Demographic Health Surveys from 29 Sub-Saharan African countries, we examine how a woman’s deviation from community norms is associated with modern contraception use. Stepwise analysis was conducted and then separate random- effects logistic regression models were fitted to examine relationships between modern contraception use and positive and negative deviance on socioeconomic characteristics, gender and fertility norms, and health knowledge and media exposure. Results suggest that deviance in all three domains is associated with modern contraception use; however, relationships between deviance and modern contraception use vary by variable and by place. Findings highlight the importance of using context-specific deviance approaches for improving public

    Positive Deviance: A Non-Normative Approach to Health and Risk Messaging Oxford Research Encyclopedia of Communication Positive Deviance: A Non-Normative Approach to Health and Risk Messaging Arvind Singhal and Lucia Dura Subject: Communication Theory, Health and Risk Communication Online Publication Date: Mar 2017 DOI: 10.1093/acrefore/9780190228613.013.248 Summary and Keywords The Positive Deviance (PD) approach is based on the premise that every community has individuals or groups whose uncommon behaviors and strategies enable them to find better solutions to problems than their peers although everyone has access to the same resources and challenges. In contrast to traditional problem-solving approaches that begin with an expert- driven analysis of “what is not working” with people—their explicit needs, deficits, problems, and risks—followed by attempts to plug those gaps, the PD approach focuses on identifying “what is working.” PD offers a systematic framework to identify assets, indigenous knowledge, and home-grown solutions, and to amplify them for wider adoption. The PD approach was operationalized and systematized in the early 1990s in Vietnam to address malnutrition. At the time, 65% of children under five were malnourished. Instead of looking for the causes and applying best practices, PD pioneers looked for children from very poor families who were well-nourished. Through community-led efforts, they determined the existence of positive deviants, identified their behaviors and strategies, and amplified them. The process was replicated across 14 villages—each identifying its own batch of local practices—and malnutrition decreased by 85%. These actions led to PD as we know it today in the form of the “6 Ds”: Define, Determine, Discover, Design, Discern, and Disseminate.

  • Chapter 3 Practice Positive Deviance for Extraordinary Social And
    CHAPTER 3 PRACTICE POSITIVE DEVIANCE FOR EXTRAORDINARY SOCIAL AND ORGANIZATIONAL CHANGE Jerry Sternin ABSTRACT In his own words, Jerry Sternin, widely known as "the father of applied Positive Deviance, " explains the story of how an acute crisis led him to the practice of Positive Deviance (PD). He tells how he was propelled, over a twelve-year period to develop and amplify the approach which has enabled communities of more than 2.2 million people in Vietnam to sustain the reduction of childhood malnutrition and has been replicated in 24 other countries around the world. The chapter includes a step-by step approach to positive deviance, a formula for positive deviance, exceptional stories of change within societies, and a "how to" and "what-to-do" approach to positive deviance that could be applied within organizations, institutions, or your own society. SUMMARY Positive Deviance (PD) is based on the belief that in every community there are certain individuals/entities whose special practices or strategies enable them to find a better solution to a pervasive problem than their neighbors who have access to exactly the same resources. We call these individuals "positive deviants". The PD design provides a tool to enable the community to discover the positive deviants' uncommon, but demonstrably successful strategies. The community then analyzes those strategies retaining only those that are accessible to all its members. Finally, the community designs an intervention, enabling all its members to access and practice the newly discovered PD strategies. PRACTICE POSITIVE DEVIANCE FOR EXTRAORDINARY SOCIAL AND ORGANIZATIONAL CHANGE 21 INTRODUCTION Nasirudin, the great Sufi mystic, appears in different guises in different stories.

For more information: CORE Group www.coregroup.org Recommended Citation Nutrition Working Group, CORE Group, Positive Deviance / Hearth Essential Elements: A Resource Guide for Sus- tainably Rehabilitating Malnourished Children (Addendum), Washington, D.C: June 2005. Acknowledgements This publication was written by Judiann McNulty, a consultant to the CORE Group. Abstract A Positive Deviance/Hearth Nutrition Program is a home- and neighborhood-based nutrition program for children who are at risk for protein-energy malnutrition in developing countries. The program uses the “positive deviance” approach to identify those behaviors practiced by the mothers or caretakers of well-nourished children from poor families and to transfer such positive practices to others in the community with malnourished children. The “Hearth” or home is the location for the nutrition education and rehabilitation sessions. This Addendum updates the CORE Group’s February 2003 Positive Deviance/Hearth Manual. It gives an overview of appropriate settings for and essential elements of a PD/Hearth intervention.

  • Positive Deviance Hearth Resource Guide
    Positive Deviance/Hearth: A Resource Guide for Sustainably PPositiveositive DevianceDeviance /Hearth/Hearth Rehabilitating Malnourished Children Positive Deviance/Hearth is a successful home-based & neighborhood-based nutrition program for children who are at risk for malnutrition in developing countries. It has enabled hundreds of communities to reduce their levels of childhood malnutrition and to prevent malnutrition years after the program’s completion. The “positive deviance” approach is used to find uncommon, beneficial practices by mothers or caretakers of well-nourished children from impoverished families. Once identified, ways are sought to spread these practices and behaviours to others in the community with malnourished children. A “Hearth” is the setting of the nutrition education and rehabilitation part of the program. Suggesting a family around a fireplace or kitchen, Hearths are carried out in home settings where caretakers and volunteers prepare “positive deviant foods”. They practice beneficial childcare behaviors and feed malnourished children with extra energy-rich/calorie-dense supplemental meals. Sprinkled with helpful field examples, useful tools and ideas, this guide explains step by step how to: ♥ identify at-risk children AA RResourceesource GuideGuide ♥ conduct a Positive Deviance Inquiry forfor SustainablySustainably RRehabilitatingehabilitating ♥ conduct Hearth sessions and ♥ set up a monitoring and evaluation system MalnourishedMalnourished ChildrenChildren CORE Incorporated 220 I Street, NE Suite 270 Washington DC 20002 (USA) telephone (202) 608-1830 / fax (202) 543-0121 Child Survival Collaborations and Resources Group www.coregroup.org Nutrition Working Group February 2003 The CORE Group he Child Survival Collaborations and Resources Group (The CORE T Group) is a membership association of more than 35 U.S.

  • Determinants of Normal Haemoglobin Concentration Among Children In
    www.nature.com/scientificreports OPEN Determinants of normal haemoglobin concentration among children in Ghana: a positive deviance analysis of nationally representative cross-sectional survey data Dickson A. Amugsi Anaemia among children under 5, is a public health problem of serious concern. In Ghana, an estimated 8 out of every 10 children are anaemic. This study employed a novel approach to investigate the determinants of normal haemoglobin (Hb) concentration among children aged 6 to 59 months, using data from the Ghana Demographic and Health Surveys. The results showed that maternal schooling was positively associated with normal Hb concentration among children. Children of non-anaemic mothers were 1.67 (CI = 1.32, 2.10; P < 0.001) times more likely to have normal Hb concentration relative to children of anaemic mothers. Compared to mothers who had less than 4 antenatal care (ANC) visits, mothers who had at least 4 ANC visits increased the odds of their children having a normal Hb concentration by 1.62 (CI = 1.09, 2.40; P < 0.018). Children living in middle and rich households had respectively 1.48 (CI = 1.06, 2.07; p < 0.021) and 1.59 (CI = 1.08, 2.33; p < 0.018) increased odds of having a normal Hb concentration relative to those living in poor households. Maternal education, anaemia, ANC attendance, and household wealth index are strong determinants of normal Hb concentration among children in Ghana. Strategies aimed at addressing childhood anaemia should take into account maternal anaemia, education, poverty and ANC attendance. Anaemia, defned as blood haemoglobin concentration lower than normal1,2 is a pervasive problem among chil- dren under fve years of age.
