Effective and emotionally nurturing parenting practices constitute salient protective factors in the lives of children and youth. Although social workers have influenced in important ways the scholarship associated with the development and dissemination of culturally relevant evidence-based parenting interventions for underserved populations, low-income ethnic minorities continue to lack access to culturally relevant and efficacious parenting interventions in the United States due to widespread mental health disparities. Addressing this gap in service delivery is necessary, particularly because populations exposed to historical oppression and intense contextual adversity are at an increased risk for engaging in harsh parenting practices. The purpose of this paper is to reflect on the process of change that we have documented as a group of 130 underserved Latino/a immigrant parents were exposed to a culturally adapted evidence-based parenting intervention. An emphasis on describing the process of change leading to improved outcomes is relevant for clinical social workers engaged in the direct delivery of preventative or clinical parenting interventions. Thus, this manuscript will focus on issues of engagement and retention of parents, with important consideration to the importance of integrating evidence-based knowledge, cultural relevance, and key principles of social work practice.
