‘Interaction structures’ between depressed adolescents and their therapists in short

Identify the core ‘interaction structures’ between therapists and depressed adolescents within and across two common forms of psychotherapy. A total of 70 audio-recorded psychotherapy sessions representing short-term psychoanalytic psychotherapy (STPP) and cognitive behavioural therapy (CBT) with youth aged 12–18？years old were coded with the Adolescent Psychotherapy Q-set (APQ), a newly developed instrument. Data included different therapist-patient dyads and stages in treatment and were analysed with cluster analysis. Three distinct interaction structures between therapists and depressed adolescents: two influenced by the therapists’ techniques and one more influenced by the young people’s attitude to therapy. When there is a collaborative working relationship between therapists and depressed young people, the therapy process is influenced by the therapists’ techniques; while when there is a poor working relationship, the techniques used by therapists of different theoretical orientation become more similar with the aim of engaging the young person in the process
