Abstract Background Inequities in service utilization between immigrant families and native populations have emerged within the Nordic welfare countries, highlighting the need for culturally sensitive parenting support. Despite the proven efficacy of parenting interventions, their implementation phases have not been adequately addressed in extant implementation research, particularly regarding structural racism and inequities. This study aims to contribute to the literature from an implementation perspective by describing a pilot of ‘Being a Parent in Finland,’ a culturally sensitive group-based intervention for migrant parents. Its specific focus is on investigating barriers to and facilitators of implementation outcomes from the perspectives of service providers. Methods The qualitative data consisted of thematic interviews (N = 6) with service providers (N = 9) compiled at distinct phases of the pilot from 2021 to 2023. In addition, data triangulation was utilized through document analysis of 125 pages of various documents regarding the pilot as a supplementary data collection method. Content analysis was conducted on the data using Atlas.ti 23. Results The findings stress the alignment of the target group, service placement, and preventive measures for enhancing parenting intervention’s acceptability, appropriateness, and feasibility. Implicit objectives, such as perceiving the target group as ‘at-risk,’ can impede intervention success and exacerbate stigmatization of the target group. Culture- and context-specific adaptations, and community engagement foster parental trust and intervention accessibility. Conclusions The findings underscore the significance of congruent objectives, community engagement, and adaptive iterations in preventive parenting interventions. Advocating for these elements in implementation strategies is crucial for reducing stigmatization and enhancing equity and efficacy in services tailored to minority parents. Key messages • Acknowledging equity in both implementation research and strategies is paramount. • Implementing trust-building is crucial for culturally sensitive parenting interventions.
