The diagnostic assessment, or intake interview, occurs during the first one or two sessions of therapy. This is a time for client and therapist to become acquainted with one another. One of the most important factors influencing the success of therapy is the match between the therapist and the client. The intake interview is also the time for the therapist to collect information so that she can assign the most appropriate diagnosis. The therapist will inquire about the events that led the client to decide on attending therapy and any symptoms the client has. In order to gain a holistic understanding of the client’s situation, the therapist will also explore the client’s personal history, family history, and medical history. Finally, the client and therapist will develop specific goals for treatment and a plan for achieving these goals.
