This is believed to be the last interview given by Dr Bowlby. In it, in addition to the paramount role of early separations and losses in future personality development, he stresses the importance of research as the basis of advancing knowledge, and the value of prospective rather than retrospective information for all psychological approaches in child psychiatry; the extreme importance of assessing present and past behaviour; the similarities (evaluation of psychological development) and differences (observation versus speculation) between his attachment theory, psychoanalysis, and cognitive therapy; and his “share of criticism” from former psychoanalytic colleagues. In addition, he provides essential information about the development of troubled children, their recognition, clinical assessment, and treatment; how to manage children in hospital and how to help them to deal with separations from their parents and with adoption. He also discusses his approach to psychotherapy.
