Purpose: Acquired brain injury (ABI) profoundly impacts the whole family. This studyexplores family identity using a relational, strengths-focused framework to understandhow families navigate ABI together.Materials and methods: Four adult family units, consisting of four survivors of ABI(1–18 years post-injury) and seven family members (aged 24–74), were interviewedtogether two/three times. Using Narrative Analysis an overall narrative (gestalt) of ABIas an ongoing family life transformation, encompassing both disconnecting andunifying narratives, was construct.Results: Six interconnected stories of family identity were identified: (1) Disjointednessin response to the trauma of ABI; (2) Closeness remedying disjointedness with continuityand growth; (3) Incomprehension and disablism in interactions with people; (4)Incomprehension and disablism may be mitigated through understanding, kindnessand inclusion; (5) Protectiveness from family members in tension with survivor’s wishfor independence; and (6) Humour to lighten the seriousness of ABI. Disconnectingnarratives spoke to the challenges of responding to the trauma of ABI. Unifyingnarratives could bring the family together and help manage the challenges of ABI.Conclusions: Integrating unifying and disconnecting narratives may help families tomake sense of ABI, and clinical services could embed relational and strengths-basedunderstandings into family support post-ABI.
