You have worked out what the letters mean. Now you are looking at a calendar, a bank balance, and a husband who has agreed to go to counseling but has not agreed to much else, and you need to decide who books an appointment first.
This is the practical question underneath the alphabet. Not what the credentials are — that map already exists — but which one you need, this week, in the situation you are in.
The short version: the choice between a CSAT or CPTT is not really a choice, because they are not alternatives. A CSAT treats him. A CPTT treats you. If you can only start one, start yours.
Quick answers
Do I need a CSAT or CPTT?
If you are the betrayed partner, you need a CPTT or a CCPS. A CSAT is trained to treat compulsive sexual behavior, which means the CSAT is his clinician, not yours.
Can we see the same therapist?
For individual work, no. Specialist practice gives each partner their own clinician, who then coordinate with each other. One person cannot hold both of your interests in separate rooms without a conflict.
If we can only afford one, whose comes first?
Yours. His recovery has other supports — groups, twelve-step meetings, accountability structures. Yours does not, and the trauma symptoms are happening in your body right now.
What if the betrayal was pornography, not an affair?
The same credentials apply. Partner trauma training is built around discovering hidden sexual behavior, and it does not require an affair to qualify.
The rule, in one line
The credential follows the person, not the problem.
People get stuck here because they think of “the betrayal” as one thing needing one specialist. It is two injuries in one house. He has a behavior to stop and something underneath it to understand. You have a trauma response that arrived without your consent and is running your sleep, your appetite and your body’s alarm system. Those are different problems requiring different training, and they are treated in different rooms.
So the question is never really CSAT or CPTT in the abstract. It is: who is this appointment for?
Six situations, and what to do in each
1. You want support for yourself
CPTT or CCPS. Either one. Both were trained specifically to treat the betrayed partner, one through IITAP and one through APSATS. Whichever you can reach is the right answer, and availability should decide it rather than a preference between the two organizations.
2. He is ready to get help for the behavior
CSAT. This is what the credential exists for. If no CSAT is available where you live, a licensed therapist with genuine experience treating compulsive sexual behavior is the next option — but ask directly how many such cases they carry, because a general therapist who has treated two is not the same as one who treats this weekly.
3. You can only afford one course of therapy right now
Yours. We want to be careful here, because this can sound like we are telling you to deprioritize your marriage, and it is the opposite.
He has other scaffolding available — twelve-step meetings, men’s groups, accountability partners, a great deal of free material. Those things exist in most communities and cost nothing. There is much less of that for you, the symptoms are in your body now, and if you go untreated while his recovery gets all the resources, you will end up doing what betrayed partners have done for decades: managing his process while your own goes unattended.
Start yours. Add his when you can.
4. He wants you both to see the same person
For individual therapy, this is a bad idea, and it is worth understanding why so you can say so clearly.
In specialist practice, each partner has their own clinician. He sees someone trained for his work, you see someone trained for yours, and the two professionals coordinate — meeting jointly with the couple at defined points, and each present to support their own client through something like a full disclosure. That structure exists because your interests are not identical during this stage, and one clinician holding both sets of interests in separate confidential rooms is placed in an impossible position.
There is also a simpler reason. If the same person hears his account first, you will spend your sessions wondering what she already believes. You will never be able to fully test that worry, and it will sit in the room with you.
5. It was pornography or webcams, not a physical affair
The credentials still apply, and you are not overreacting by seeking a specialist.
Partner trauma training was built around discovering concealed sexual behavior — the deception, the double life, the reordering of everything you thought you knew. Whether that behavior involved another body in a hotel room is a real distinction, but it is not the distinction that determines whether your nervous system responds as though the ground moved.
6. You already have a therapist you trust who holds none of these letters
Do not fire her by default. A clinician who already knows you and has your trust is a real asset, and starting over costs something.
Ask her three things. Has she treated betrayal trauma before, and roughly how often. Is she willing to consult with someone who specializes in it. Does she think of what happened to you as a trauma or as a marital problem.
The third answer tells you the most. A good generalist will answer it honestly, and some will tell you outright that this is outside their depth — which is a mark of competence, not a failure.
Can one person hold both credentials?
Yes, and many do. The two organizations recognize each other’s training explicitly. A clinician who already holds the CSAT has a shortened path to IITAP’s partner credential and a reduced consultation requirement for the APSATS one, so clinicians who work in this field frequently carry more than one set of letters.
That is a good sign about a practice. It is not permission to be treated by the same individual as your husband. A practice with both credentials on staff is exactly what you want — two clinicians under one roof, already used to coordinating. A single clinician offering to see you both individually is a different thing.
What to say when you call
Most specialists offer a free consultation of fifteen or twenty minutes. You do not need a script, but if the words are hard to find right now:
“My husband’s sexual behavior came out recently. I am looking for my own therapist, not couples counseling yet. Do you work primarily with betrayed partners? And do you hold a partner trauma credential — CPTT or CCPS?”
Three things you are listening for in the answer. Whether she treats partners specifically rather than couples generally. Whether she has a referral for your husband rather than offering to see him herself. And whether she asks how you are sleeping — because a clinician who reaches for the body early is one who understands what this is.
If neither exists where you live
Large parts of the country have no CPTT or CCPS within driving distance. Three things are true about that.
Most of these clinicians now work by video, and licensure is by state rather than by town — so your search area is your whole state, not your county. A trauma-informed therapist who takes betrayal seriously and is willing to consult with a specialist is a legitimate second option, not a consolation prize. And a trained partner coach, while not a licensed clinician, may be more available and more experienced with this specific wound than anyone taking new patients near you.
Something now beats the perfect person in six months.

Frequently asked questions
Do I need a CSAT or CPTT if I am the betrayed partner?
A CPTT, or a CCPS, which is the equivalent credential from APSATS. Both train licensed clinicians specifically to treat the betrayed partner. A CSAT is trained to treat compulsive sexual behavior, which makes a CSAT your husband’s clinician rather than yours.
Can my husband and I see the same therapist individually?
Specialist practice keeps individual work separate. Each partner has their own clinician, and those clinicians coordinate with each other, meeting jointly with the couple at defined points and each supporting their own client through processes like full therapeutic disclosure. One clinician holding both partners’ individual work creates a conflict during a stage when your interests are not identical.
If we can only afford one therapist, who should go first?
The betrayed partner. The person with compulsive sexual behavior has additional low-cost supports available, including twelve-step meetings and men’s groups, while there is far less equivalent scaffolding for the partner. Trauma symptoms are also present immediately, and leaving them untreated while all resources go to his recovery repeats the pattern the field spent decades correcting.
Does a CSAT treat the betrayed partner too?
Some CSATs hold partner credentials as well and do excellent work with partners. But the CSAT credential itself is oriented toward treating compulsive sexual behavior. If a practice offers you a CSAT as your own individual therapist with no partner credential attached, ask directly what training they have in partner trauma.
Do these credentials apply if the betrayal was pornography rather than an affair?
Yes. Partner trauma training is built around the discovery of concealed sexual behavior and the deception surrounding it, which does not require a physical affair. Betrayed partners commonly experience the same trauma responses whether the behavior involved pornography, webcams, or an affair.
Can one therapist hold both CSAT and CPTT?
Yes, and it is common. IITAP shortens the supervision requirement for clinicians who already hold the CSAT, and APSATS reduces its consultation hours for clinicians holding CSAT or CPTT. A practice with both credentials on staff is well positioned to treat a couple, using two clinicians rather than one.
What if there is no CPTT or CCPS near me?
Most specialists now offer video sessions, and clinical licensure covers an entire state rather than a local area, so search statewide. A trauma-informed therapist willing to consult with a specialist is a reasonable alternative, as is a trained partner coach, keeping in mind that coaching is not licensed clinical care.
A note on what this is. We are not therapists, and this article is educational rather than clinical. Nothing here is a diagnosis, a treatment plan, or a substitute for care from a qualified professional. Credential requirements and recognition agreements are set by the issuing organizations and change periodically; details were verified against IITAP and APSATS published requirements in July 2026.
