IFST parts are not the same parts as in DID
Right. And IFST isn’t the only non-DID therapy that involved seperating the self into distonct parts. For example, schema therapy does something similar through schema modes.
Working with the “inner child” is really about working with the state of feeling vulnerable and scared. It’s more about addressing (your) beliefs, emotions and behaviours that are involved with that vulnerability, and trying to find a way to resolve them, as part of the healing process.
But for a lot of people, language is incredibly important. And distinguishing this vulnerability, which arises from unresolved traumatic experience, as a distinct “part”, is a very particular way of dealing with those issues. And all too often, it leads to assigning an entire personality, distinct from the self, oftentimes with its own name and evem thhe ability to speak as if seperately from the person actually in therapy.
In fact, there is no child in the room, there’s only the patient. And they don’t actually have a seperate personality. I’ve certainly seen it play out many times in non-DID patients where creating that inner child, creates a new issue. For some people (not all), the child personality, which was only meant to play a role in therapy, takes on its own life outside of therapy. This disintegrated concept of self, for some patients, creates as much dysfunction as it resolves.
A good trauma therapist dealing with a non-DID patient should be able to address the needs of the individual patient. And if it is being made clear by the patient that they don’t relate to the concept pf a fragmented self, and have reason to believe that DID is not at play, then working through recovery issues such as vulnerability should be well-within their scope of practice without having to resort to persuading their client that they should consider themselves as fragmented.
For some non-DID people, identifying distinct parts of their personality is helpful. For others, it can (and too often does) create a fragmented identity that ultimately needs reintegration.
