Empirical Evidence

The Foundation for Self Leadership supports the rigorous examination of the efficacy of various IFS applications through the independent gathering and analysis of empirical evidence, both hard and soft evidence.

NREPP accepted and recognized IFS Therapy as an evidence-based modality

In the second half of 2014 and following an independent, rigorous review, the National Registry of Evidence-based Practices and Programs (NREPP), accepted for review a comprehensive application by the Foundation for Self Leadership, prepared on behalf of The Center for Self Leadership and the community. The application was a formal request to consider IFS Therapy as an evidence-based psychotherapeutic modality. The application had been submitted in early 2014 and was included in a new cohort of applicants subject to some new NREPP guidelines for review.

NREPP, which was an entity operating within the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA), had engaged private researchers to review all submissions independently and conduct a two-tier rigorous evaluation, examining the quality of the research about IFS, which had to be based on a randomized clinical trial (RCT), and the capacity to disseminate the named modality.

The application revolved around a proof-of-concept RCT study, completed and published in a peer-review research journal, by Nancy Shadick, MD, MPH; Nancy Sowell, MSW, LICSW; and collaborators.

In late 2015, the Foundation was notified that NREPP accepted and recognized IFS Therapy as an evidence-based modality. See story on the Foundation’s website and the announcement to the IFS community at the 2015 IFS Conference.

As a clinical treatment, it was independently confirmed that IFS Therapy leads to five outcomes, one effective and four promising. The outcomes covered areas of efficacy that appeared to deal with positive effects on body, mind, and spirit—among them: improving general functioning and well-being, reducing depression and depressive symptoms, and improving resilience and self-concept
