Describing a treatment methodology for the psychotherapy of adult patients with borderline personality disorder or borderline traits, this book integrates ideas and techniques from biological, family systems, psychodynamic and cognitive-behavioural therapies. In addition, it aims to fill a need for a problem-focused, clinically oriented and operationalized treatment manual for patients in individual psychotherapy for the disorder that specifically addresses major ongoing family factors that trigger and reinforce the patient's self-destructive or self-defeating behaviour. Although the book contains some theoretical material about borderline family dynamics - the understanding of which is necessary for the therapist to employ the recommended therapy techniques - it is primarily devoted to practical solutions and specific clinical recommendations for commonly-encountered problem patient behaviour. Psychotherapists from all disciplines who treat the disorder may find this book useful.
