Systemic Sex Therapy, third edition integrates couple and sex therapy to inform the treatment of sexual problems and to give beginning clinicians the abilities and confidence they need to produce change in their patients’ lives. Grounded in the Intersystem Approach, the book considers the biology, psychology, couple dyad, family-of-origin, and larger contextual factors of any sexual disorder or issue. Each chapter examines the definition and description of a sexual disorder or issue, its etiology, assessment, treatment, research, and future directions. This thoroughly revised edition presents 18 updated chapters consistent with the DSM-5 and features new content on sexuality and aging, infidelity, sexual interest/arousal disorder, disability, and kink/BDSM. Experts in the field discuss all the major sexual dysfunctions along with new chapters on culture, technology, and their interplay with sexual functioning. An essential text in the field, Systemic Sex Therapy sets out a conceptual framework for graduate students in couple and family therapy programs looking to develop a comprehensive, integrative understanding of sexual issues.
