ABSTRACT

This chapter reviews the existing aetiological theories for sex addiction. The chapter covers traditional models, such as attachment failure, trauma re-enactment and intimacy problems, as well as newer models built upon advances in the scientific understanding of neurobiology as it relates to attachment, affective co-regulation and the medical model of addiction. Case studies are provided for each of the theories. The chapter ends with a discussion of the importance of a proper differential diagnosis, and a warning to therapists of the possible iatrogenic harm that can be caused by the improper application of aetiological models, as it informs the patient’s treatment plan.
