Background: As of March 2021, there were 57380 foster children living with 45370 foster families in England (Fostering Network, 2021). Looked after children (LAC) are one of the most vulnerable groups in society and are at an increased risk of experiencing a range of complex needs such as physical, educational and mental health needs (Hare & Bullock, 2006). These outcomes are likely to follow LAC into adulthood, where they are at increased risk of becoming homeless (Dixon, 2008), experiencing substance abuse difficulties and being involved in criminal activities (Gypen et al., 2017). As such, it is important to explore different interventions that may improve outcomes for foster children, by supporting the development of successful attachments to their caregivers (in this instance foster carers). For the purposes of this research, Video Interaction Guidance (VIG) is the intervention that will be explored in its ability to positively impact the relationship between a foster child and their foster carer. Aims: The aim of this research was to gain an in-depth understanding of foster carers’ and VIG guiders’ lived experiences and understanding of how to build successful fostering relationships, and their lived experience of delivering or taking part in VIG. Methods: Semi-structured interviews were used to gather the participants’ experiences of developing successful fostering relationships and taking part in VIG. These interviews were then analysed using Interpretative Phenomenological Analysis and Thematic Analysis. Conclusion: The findings identified as a result of the data analysis included VIG being viewed as a catalyst for empowering foster carers. By providing them with the time and space to reflect on their positive attributes as carers, it helped to facilitate positive behaviour change on the part of the foster carers and supported them in reframing the relationship they had with their foster child. Future recommendations for practice include the importance of considering how the VIG process, and how the film will be used, are communicated to clients as well as the necessity for further exploration into child experiences of VIG. The importance of carefully selecting foster carers who are open to the use of relational and therapeutic approaches within the context of a fostering relationship was also recognised.
