Resource Therapists are very interested in sound research and building evidence of parts therapy efficacy.
This takes both time, energy, and a bit of expertise. Gordon Emmerson PhD has a fantastic two-day workshop on conducting research and publishing your results. As President of Resource Therapy International and a former Statistics and Psychology Professor, he fully supports research into RT.
I was prompted to write after seeing a Facebook post in an EMDR group I belong to. Specifically, the person was curious as to whether IFS and EGO State had an evidence base. The answer is yes!
Ego State Therapy has had studies published which support its efficacy. It’s worth noting Resource Therapy is also known as Advanced Ego State Therapy.
So let me give you some of the research available to help both you and those that need to understand the efficacy of parts therapy.
A single 5-6 hours manualized abreactive ego state therapy session has recently been subjected to two placebo-controlled investigations meeting evidence-based criteria. Ego state therapy was found to be a highly effective and durable treatment for posttraumatic stress disorder. Apparently, ego state therapy works because it is emotion focused, activates sub-cortical structures, and because the supportive, interpretive therapist reconstructs the patient’s personality to be resilient and adaptive. In this article the author reviews the treatment procedures and presents the findings of both studies.
They cite the following further articles:
Using manualized abreactive Ego State Therapy (EST), 30 subjects meeting DSM-IV-TR and Clinician-Administered PTSD Scale (CAPS) criteria were exposed to either 5-6 hours of treatment or the Ochberg Counting Method (placebo) in a single session. EST emphasized repeated hypnotically activated abreactive “reliving” of the trauma and ego strengthening by the cotherapists. Posttreatment 1-month and 3-month follow-ups showed EST to be an effective treatment for PTSD. Using the Davidson Trauma Scale, Beck Depression II, and Beck Anxiety Scales, EST subjects showed significant positive effects from pretreatment levels at all posttreatment measurement periods in contrast to the placebo treatment. Most of the EST subjects responded and showed further improvement over time.

The author describes ego-state therapy. This psychotherapy is used for treating multiple personality disorders. The author mentions the theoretical background of this method, and practical points. Initially, ego-state therapy was developed as a type of hypnotherapy, but it evolved as a safe therapeutic method in combination with trauma processing therapies. The author presents a case study, and discusses the clinical significance of this treatment.

Interestingly they use they use the Resource Therapy term Vaded Ego States. As far as I know Gordon Emmerson PhD was the first person to use Vaded States. In RT we have specific steps to process these parts often holding trauma and rejection.
Resource Therapy has sidestepped the need for hypnotherapy. This allows more clinicians to learn its powerful methods.
