Betrayal Trauma Credentials: CSAT vs CPTT vs CCPS Explained

You have a list of names. Some came from a friend who has been through this, some from a search you made at two in the morning, some from a directory your church handed you. Every name has letters trailing behind it. CSAT. CPTT. CCPS. LMFT. LPC. APSATS-trained. Certified Partner Coach.

You are trying to make one of the more consequential decisions of your life — who you will let near the worst thing that has ever happened to you — and the field has handed you an alphabet.

Here is what nobody tells you plainly: those letters are not decoration, and they are not interchangeable. They tell you which of two different training houses a person came from, whether they were trained to treat you or to treat him, and whether they hold a clinical license at all. Once you can read them, the list on your kitchen counter sorts itself.

This is the map.

Two houses, not one field

Almost all of the confusion in this alphabet comes from a single fact: there are two separate organizations training people in this work, and they use different letters for similar-sounding roles.

IITAP grew out of the sexual addiction treatment world founded by Patrick Carnes. Its original and best-known credential is the CSAT. It later added a partner-focused track.

APSATS came from the other direction. It was formed specifically around the needs of betrayed partners, and its founding president was Barbara Steffens — whose research reframed this entire field. Before her work, betrayed wives were routinely treated as codependents who had enabled the behavior. Her 2006 study with Robyn Rennie found that most of the wives surveyed met every criterion for post-traumatic stress except one — the requirement, since revised, that the event be life-threatening. The problem was not a character flaw in the wife. It was a trauma response in her body, and the diagnostic manual has since caught up.

That history matters when you are choosing. It is the difference between a model that begins with addiction and adds a partner track, and a model that begins with the partner.

The credentials, one at a time

CSAT — Certified Sex Addiction Therapist (IITAP)

The oldest and most widely recognized credential in this space. A CSAT is trained to work with the person engaged in compulsive sexual behavior.

To hold it, a person must already be fully licensed through a state board, hold a master’s degree or higher in a mental health field, and have at least five years of clinical experience. On top of that comes a four-module training program and a minimum of thirty hours of supervision with an approved CSAT supervisor.

This is a serious credential. It is also, by design, oriented toward your husband’s treatment rather than yours. Many CSATs do excellent work with couples, and some hold partner credentials as well. But if a practice offers you “our CSAT” as your own individual therapist and nothing more, that is a question worth asking out loud.

CPTT — Certified Partner Trauma Therapist (IITAP)

IITAP’s partner-facing credential. Same licensure floor as the CSAT: state license as a social worker, therapist, doctor or psychiatrist, a master’s degree or higher, and a minimum of five years of clinical experience. Training is two intensive four-day modules plus ten hours of clinical supervision, completed within two years. Clinicians who already hold the CSAT are exempt from the supervision requirement, having done it during CSAT training. Certification renews every two years with fifteen continuing education hours.

The faculty who teach these modules include Kevin Skinner and Sheri Keffer — names you may recognize if you have been reading in this field.

APTT — Associate Partner and Trauma Therapist (IITAP)

The same training as the CPTT, held by a clinician with fewer than five years of clinical experience. Not a lesser training. A less experienced clinician. That distinction is worth holding lightly rather than harshly — some of the most attuned partner work is done by people early in their careers, and some of the least attuned is done by people thirty years in.

CCPS — Certified Clinical Partner Specialist (APSATS)

APSATS’s credential for licensed clinicians. It is built entirely on the Multidimensional Partner Trauma Model, taught in a four-day certification training, after which the candidate enters a supervised consultation period.

The structure of that consultation period tells you something about how the organization thinks. The number of required hours scales to what the clinician already brings: thirty hours for an associate or intern-level clinician, twenty for a fully licensed clinician, fifteen for someone already holding the CSAT, ten for someone already holding the CPTT. Ten of those hours must be with one designated primary supervisor, and at least five of those must be one-on-one rather than in a group.

Certification cannot be completed sooner than nine months after training, and must be finished within twenty-four. To apply, a candidate documents 125 hours of face-to-face therapy with partners and couples, submits a written case study, two professional references, proof of licensure and liability insurance, and a fee.

A clinician who has completed the training but is still working toward full licensure carries CCPS-A until the license is issued.

CPC — Certified Partner Coach (APSATS)

This one requires the most care, because it is the credential most often misread.

A CPC is not a licensed therapist. A CPC is a coach who has been trained in the same partner trauma model. APSATS holds them to a real standard — before they may even register for the training, coaches must have completed at least sixty hours of coach education through a program accredited by the International Coaching Federation or the Center for Credentialing & Education, and to certify they must hold an active credential from one of those bodies. They complete thirty consultation hours and the same 125 documented client hours, case study, references, liability insurance and fee as clinicians.

So this is not a weekend certificate. It is also not clinical care. A coach cannot diagnose, cannot bill insurance, cannot provide treatment for post-traumatic stress, and is not bound by the same licensing board that would hear your complaint if something went wrong.

That does not make coaching the wrong choice. For many women, a trained partner coach is more available, more affordable, and more experienced with this specific wound than the licensed generalist in their town. It makes coaching a different choice, and one you should make knowingly rather than by accident.

The letters that come first

Every credential above sits on top of something more basic, and it is the part people skip.

LPC, LCSW, LMFT, LPCC, PhD, PsyD — these are state licenses and academic degrees. They are what makes someone a therapist. CSAT, CPTT and CCPS are specializations layered on top. A person can hold a specialization without holding a license, which is exactly what the coach credential is.

So the order of operations when you are looking at a name is: license first, specialization second. If you cannot find a license, you have not found a therapist. You may have found something useful — but call it what it is.

What the letters cannot tell you

Here is the part that would be dishonest to leave out.

Credentials tell you what training a person completed. They do not tell you whether that person will be safe for you. We have talked to women who sat across from beautifully credentialed clinicians and left each session feeling smaller. We have talked to women whose steadiest support came from someone with no specialty letters at all who refused to rush them.

The letters narrow the field. They do not choose for you. What tells you whether someone is right is the first conversation — whether they treat what happened to you as a wound rather than a symptom of the marriage, whether they can sit with your body’s reactions without trying to talk you out of them, whether they let your timeline be yours.

Most specialists offer a free fifteen or twenty minute consultation. Use it — here is what to ask. You are allowed to interview them.

How to check a credential yourself

1. Verify the license first. Every U.S. state has an online license lookup for its counseling, social work and psychology boards. It takes about ninety seconds and tells you whether the license is current and whether there have been disciplinary actions.
2. Verify the specialty second. Both IITAP and APSATS maintain public directories of the professionals they have certified. If someone claims a credential and does not appear, ask about it directly — there are legitimate reasons a listing lapses, and there are other reasons.
3. Ask what “trained” means. “APSATS-trained” and “APSATS-certified” are different statements. Attending a training is not completing a certification. This is a fair and ordinary question to ask, and how someone answers it tells you a great deal.
4. Ask who they treat. Specifically: “Do you work primarily with betrayed partners, with the partner who was unfaithful, or with couples?” You want to know whose interests the person across from you was trained to hold.

Which one do you need?

If you are the betrayed partner and you are looking for support that is yours alone, you are looking for a CPTT or a CCPS. Both were trained for your side of this.

If your husband is seeking his own treatment, he is looking for a CSAT, or for a licensed therapist with real experience in compulsive sexual behavior.

If you are considering couples work, the important question is not which letters the couples therapist holds but whether both of you already have your own individual support in place. Couples work that begins before the betrayed partner has her own footing has a way of going badly, and that is a subject that deserves its own conversation.

And if what you can access right now is a trained coach, a support group, or a good general trauma therapist rather than a specialist — that is not failure. It is a starting place. Almost nobody assembles the whole team in the first month.

Frequently asked questions

What is the difference between a CSAT and a CPTT?

Both credentials are issued by IITAP and both require a state clinical license, a master’s degree or higher, and at least five years of clinical experience. The difference is who they are trained to treat. A CSAT, or Certified Sex Addiction Therapist, works with the person engaged in compulsive sexual behavior. A CPTT, or Certified Partner Trauma Therapist, works with the betrayed partner.

What does APSATS stand for and what does it certify?

APSATS is the Association of Partners of Sex Addicts Trauma Specialists. It certifies professionals in its Multidimensional Partner Trauma Model. Licensed clinicians who complete the process earn the CCPS, or Certified Clinical Partner Specialist. Coaches earn the CPC, or Certified Partner Coach. Its founding president was Barbara Steffens, whose research reframed betrayed partners as trauma survivors rather than codependents.

Which credential should a betrayed partner look for?

A betrayed partner seeking her own individual support should look for a CPTT or a CCPS. Both train licensed clinicians specifically to treat the partner rather than the person who was unfaithful. A CSAT is trained primarily for the other side of the marriage, and a CPC is a trained coach rather than a licensed clinician.

Is a Certified Partner Coach a licensed therapist?

No. A CPC is a coach trained by APSATS in partner trauma. The requirements are substantial, including at least sixty hours of accredited coach education, an active ICF or CCE credential, thirty consultation hours, and 125 documented client hours. But coaching is not clinical treatment. A coach cannot diagnose, cannot bill insurance, and is not overseen by a state licensing board.

What is the difference between CPTT and APTT?

They reflect the same IITAP training. A clinician with at least five years of clinical experience earns the CPTT, or Certified Partner Trauma Therapist. A clinician with fewer than five years earns the APTT, or Associate Partner and Trauma Therapist. The distinction is years of clinical experience, not depth of partner trauma training.

What does CCPS-A mean?

CCPS-A is the designation APSATS gives a clinician who has completed the certification process but is still working toward full state licensure, such as an associate, intern, or limited licensed clinician. Once full licensure is granted and documented, the designation converts to CCPS.

How do I verify a therapist’s betrayal trauma credentials?

Check the state clinical license first through your state licensing board’s online lookup, which also shows any disciplinary history. Then check the specialty credential through the IITAP or APSATS professional directory. Ask whether the practitioner is trained or certified, since attending a training is not the same as completing certification.

Do I need a specialist, or will any trauma therapist do?

A skilled general trauma therapist can help a great deal, and access matters more than perfection. Specialist training adds familiarity with the particular shape of this injury, including triggers, hypervigilance, staggered disclosure, and the question of full disclosure, so less of each session is spent explaining the terrain. If no specialist is available, look for a trauma-informed therapist who does not treat betrayal as an ordinary marital conflict.

My church recommended a counselor. How do I know if they are qualified?

Ask two questions. Does the counselor hold a state clinical license, and how many betrayal trauma cases have they carried. Faith-integrated care and clinical competence are not opposites, and no one should have to trade one for the other. A pastor, a biblical counselor, and a licensed therapist who shares your faith are three different things with three different levels of training and accountability.
