L&D services run across England, for anyone aged 10 and over (all-age model). Some research has shown that L&D is helpful, but the evidence is mixed and much of the research has not focused on children. Here, we present a summary of the research and the recommendations presented to NHS England. The study aimed to look at how L&D was delivered for children. Part one was a Rapid Realist Review (RRR) of the literature and undertaking realist interviews with people involved in developing and evaluating L&D. Part two consisted of mixed-methods data collection from six providers of L&D in England to see how L&D works. The RRR identified within the literature seven programme theories (procedural justice, child-centred approach, trauma informed approach, non-labelling, trained workforce, coordinated response and partnership working). The process evaluation showed that delivery was variable and limited by resources, which contributed to gaps in provision and the L&D model was not always working for children and in particular some children, e.g. those already known to services. A series of short- and long-term recommendations were highlighted.
