Schwartz in the 1980s and describes and integrative, nonpathological approach to psychotherapy.... The premise of IFS is that similar to the complex external family system, individuals are composed of separate and multifaceted internal parts in relationship with each other. IFS's primary focus is to work with individuals and help differentiate parts or subpersonalities in the mind.»

[...] Finally, one can foresee that IFS has limitations when it comes to incorporating systems with multiple members involved because of the increased burden in managing exponentially more individual parts.»

Journal of Systemic Therapies20 (1): 45-58. doi:10.1521/jsyt.20.1.45.19410. «Parts work can be emotional and anxiety-provoking for clients and therapists must have a rationale and direction in order to guide clients on such internal journeys. [...] Although Schwartz may disagree, we believe that IFS therapy, in general, may not work well with delusional, paranoid, or schizophrenic clients. Clients who are not grounded in reality may misuse the idea of "parts" or become more entrenched in delusional thoughts by such interventions.»
