Prevention and intervention programmes for children at risk aim to improve child well-being and resilience. They do so using both direct and indirect strategies, intervening with children but also considering broader contextual factors (such as family dynamics). Children's subjective well-being comprises five main components (physical health, mental health, self-regulation, social competence, and cognitive competence) and is predicted by person, relationship, and contextual factors. Children's resilience, or ability to beat the odds under adverse conditions, is predicted by similar protective factors. Family well-being (FWB) is one of the strongest and most consistent predictors of child well-being and resilience. Aspects of FWB (including adult health and well-being, family selfsufficiency, and family resiliency) have been shown to impact child well-being through positive parent-child interactions. However, risk factors (including poverty and living in geographic locales with limited resources or high levels of neighbourhood violence) can threaten both family and child well-being. Strategies are offered for promoting FWB as a means of supporting resilience and well-being in children at risk for violence, abuse, or neglect.Early intervention and child abuse prevention programmes have sought ways to improve child well-being and resilience directly (working one-on-one with a child) and indirectly (by improving parenting skills, thereby improving child outcomes). Research has shown that family well-being (FWB) provides a foundation on which to build positive parenting skills, and when children are parented in developmentally appropriate and supportive ways, their well-being and resilience are bolstered. There is new interest in exploring connections from FWB to child well-being, especially for vulnerable children who are at-risk for violence, abuse, or neglect. This paper will examine key components of child well-being and resilience, key components of FWB, risk factors for families, and strategies for promoting FWB as a means of supporting resilience and well-being in children at risk.Child well-being and resilience A child's subjective well-being is a critical indicator of environmental impacts on his/ her development from early childhood through adolescence (Children's Worlds, 2011;
