This second edition of The interview in social work, completely revised and updated, offers a conceptual framework of this topic mainly from the perspective of relational psychology, as well as the application of concepts to real interviews collected in different services and social work departments . The interview is one of the basic tools in the field of social sciences. Sociologists, social workers and psychologists make constant use of it, but often forget the psychodynamic aspects of the interview, which refer to the emotional exchanges between the interviewee and the interviewer. This subject has been treated very much in the framework of psychology, but has received little attention in the other areas of psychosocial intervention. Little is said about the emotional experiences that emerge in this type of personal interrelation, a negligence that can hinder the achievement of the objectives of information collection, delimitation of problems and subsequent intervention. The interview in the social work offers the broad assistance and teaching experience of the authors in this matter, for the benefit of students and professionals who exercise their functions in the broad context of social work.
