One premise for the organisation of residential care for youthis that staff are expected to relate to each young personindividually, but also to the group of young people as a whole.The relational interplay between staff and placed youths insecure unit care is fundamentally based on asymmetry, withinteractions taking place in a context of confinement. The aimhere is to explore how staff working in secure institutionalcare for youths in Sweden understand and describe theirrelationships with youth in terms that extend beyondprofessionalism, and especially their use of the familymetaphor. Fifty-three interviews with staff were analysed in atwo-step qualitative analysis, which generated three themesthat highlighted staff narratives focusing on descriptions ofparenting, sibling relationships, and closeness without usingthe family metaphor. One conclusion is that despite an overallshift away from the family metaphor, in the direction offraming residential care in professional terms, the familyconcept seems to sit quite well even in an environment withambitions to provide professional care. The family metaphormay not be the cornerstone of care, but it is eminentlypresent.
