Introduction Psychodynamic psychotherapy with children and adolescents is an approach to working with young people that draws on psychoanalytic ideas, whilst also integrating ideas from other disciplines, including developmental psychology, attachment theory and neuroscience (Alvarez, 2012; Kegerreis & Midgley, 2014; Lanyardo & Horne, 2009). Although the term 'psychodynamic therapy' covers a range of approaches, most of them share what Kegerreis & Midgley (2014) refer to as "the central idea ... that behaviour, emotions and responses have an inherent logic and meaning-a way in which the child's problems, despite their apparent unhelpfulness, make some kind of emotional sense. Their roots lie in the internal world of the child that has been built up from his earliest experiences and relationships" (p.38) i. In 2011, we published a critical review of the evidence base for psychodynamic therapy with children and adolescents (Midgley & Kennedy, 2011). In that paper, we identified 34 studies, published before March 2011, which formally evaluated therapy outcomes for children aged 3-18. Of these studies, nine were randomised controlled trials (RCTs), three had a quasiexperimental design, eight were controlled observation studies and fourteen were observational studies without a control group.
