@Ms Spock said "...it does talk about how CBT doesn't really work for complex trauma..."
Beg to differ on CBT and whether or not it is assistive for complex traumas. The techniques though need to be learned and practiced until they become a new behavior. Is it for EVERYBODY? Well probably not, but you really never know unless you endeavor to try. I did though start with the REBT stuff and when that seemed to give me improvements and some noticeable improvements moved it up to CBT.
Two articles from Anthony about CBT just off the bat, his article on Complex PTSD says, "... Cognitive Behavioral Therapy (CBT) is the optimal method for dealing with CPTSD to achieve long-term cognitive restructuring. With complex PTSD, CBT is the treatment of choice for long-term results versus short-term results. It is not uncommon for trauma therapists to use a combination of both EMDR and CBT to target traumatic aspects uniquely, depending on emotional severity and sensitivity. CBT includes Dialectic Behavioral Therapy (DBT), as DBT is a varied form of CBT.
One of the largest problems when dealing with complex PTSD is that the sufferer has a high risk of suicidality or self-injurious behavior. Therapists are often stuck between a rock and a hard place with many CPTSD sufferers, due to the legal obligation in treatment to ensure that their patient does not harm themselves or someone else. This can limit how hard they push to achieve the results needed for change."

In his article Cognitive Behavioral Therapy, he states: "... accounting for actual clinician success rates, which are on average above 85% for
CBT use in conjunction with PTSD. The Australian National PTSD course has reported rates from 50% to 90%, depending on location, course structure and physicians involved."

Do I believe Anthony's take? Yes I do.
