As a problem becomes more complex, it requires more specialized treatment. Often sex addiction has underpinnings of trauma and abuse. CSATs are trained to pick up on things that another counselor would perhaps not see.
As a Licensed Professional Counselor, one of my sub-specialties is Sex Addiction Therapy. This means that I have spent additional time with extensive training to meet the strict criteria set forth by Patrick Carnes, PhD. and the International Institute of Trauma Addiction Professionals for Certification. I am familiar with and utilize his model. The training is intensive, requiring a lot of preparation, testing, supervision, travel, and monetary investment. It consists of four, full week training modules, spanning over a period of approximately one year. Sex Addiction often presents with other addictions, and as a Certified Multiple Addictions Therapist (CMAT), I would be knowledgeable of the process.
