What was done
This was a narrative review synthesizing psychotherapeutic approaches for complex post-traumatic stress disorder (CPTSD), including cognitive-behavioral therapy (CBT), trauma-focused therapy (TFT), dialectical behavior therapy (DBT), eye movement desensitization and reprocessing (EMDR), and psychodynamic therapy. The review evaluated outcomes across core PTSD symptoms and disturbances in self-organization (DSO), along with therapeutic process factors including alliance, trust, empathy, and rupture repair.
What was found
The abstract reports no numerical findings, effect sizes, or statistical metrics. Qualitatively, standard evidence-based treatments (CBT, EMDR, exposure-based therapies) reduced core PTSD symptoms but had smaller, more variable effects on DSO symptoms. Phase-based approaches showed more substantial improvements in affect regulation, self-concept, and interpersonal functioning. Psychodynamic therapies yielded durable gains in identity and relational functioning. Therapeutic alliance, trust, rupture repair, and therapist empathy were highlighted as key drivers of safety and emotional regulation.
Why it matters
Treating CPTSD requires addressing relational and identity disturbances alongside standard trauma intrusions. The review highlights the necessity of combining structured evidence-based modalities with relational, phase-based frameworks to treat both symptom domains.
Limits
As a narrative review, it lacks a systematic search strategy, explicit study inclusion/exclusion criteria, risk of bias assessments, and quantitative pooling. The abstract does not report the number of reviewed studies, total participant sample size, or comparative effect sizes.
