How is CSCT by ISTI different than CST by AASECT?

The future of this field demands that clinical professionals integrate both sex therapy and relationship counseling in order to keep up with the challenges of contemporary practice. Integrative Sex and Couples Therapy is a new field of learning for all therapists that builds on sex therapy and relationship therapy and adds a third area: alternative forms of treatment that are designed specifically to meet the contemporary needs of today’s clients.
