Unless it is personal do you mind posting it here?
I think you're referring to my comment that I am going at the ANPs and EPs from a place of SELF.
I think this SELF energy piece is the key differentiation between structural dissociation theory and internal family systems therapy (IFS). It's like a different way of framing it.
Structural Dissociation Theory
As I understand
structural dissociation theory, the major differentiation of diagnoses has to do with how many ANPs and EPs there are.
In
single-incident PTSD, when there has been no early trauma experience or exposure, a person can fragment into one ANP (their functional, everyday self) and one EP (the emotional part that is stuck in the traumatic incident and holds all the unprocessed feelings of it).
In
complex-trauma, where there has been early or prolonged trauma experience/exposure, there can be different arrays of parts that can be hard to distinguish among. Some people have one ANP and two or more EPs. In a world of diagnoses, these people would be labeled as sufferers of complex-trauma (a different category of PTSD and not in the DSM-V except as PTSD of the dissociative type I think), or of
Other Specified Dissociative Disorder. According to van der Hart, from what I've been able to figure out, people with OSDD can have EPs that can take over executive control. Thus, they may appear to have
dissociative identity disorder, but they don't because what is taking over executive control is an EP, not an ANP.
Other people develop two or more ANPs and two or more EPs. This would be
DID. Again, according to van der Hart, et. al., DID can occur when there is complex, developmental trauma very early, and then an additional major traumatic event early on (before age 4 or 5 I think). At some point in his writing, he notes a comment like: good luck figuring out the difference between a complex and powerful EP and an ANP. What marks DID is the profound phobia among parts that lead to true amnesia (not dissociative amnesia). (This distinction still confuses me). Multiple ANPs can be seen on an fMRI.
My sense is that structural dissociation theory is an attempt to frame the personality diagnostically...hence the distinction between the words "Normal" as in "Apparently Normal Personality" and "Emotional" as in "Emotional Personality." Just the vocabulary itself bifurcates
emotion from
normality. Structural Dissociation Theory (SD) seems to me to be an attempt to help frame diagnostic categories and criteria for mental illness. I find it enormously helpful, but also at odds with the Internal Family Systems Theory (IFS). It is focused on healing illness...you are either an integrated whole personality, or you are not, and you fall on some level of SD. IFS begins with the assumption that we all have parts--whether we do or do not have PTSD, CPTSD, OSDD, or DID. This is a very, very different approach.
Internal Family Systems Theory
IFS takes as its starting point that all human beings have something called SELF energy, as well as three categories of PARTS: managers, firefighters, and exiles.
Managers seem to me to be the equivalent of ANPs in SD. Their job is to keep us functional in our daily lives.
Exiles are parts that have been walled off/silenced/locked away--parts that hold traumatic experiences. To me, these parts seem equivalent to the EPs of SD. The
managers' jobs are to prevent the emotional overwhelm of the exiles from breaking through and overwhelming the system. Therefore manager parts fall into the category of
protector parts because their job is to protect the system--keep it safe and functional in daily life.
Unlike in SD, however, IFS includes two other aspects of the personality that don't quite fit into SD theory:
firefighters and
SELF. Firefighters are considered extreme protector parts because they come in when the managers get exhausted from their jobs. Firefighters are attempts to protect the system from overwhelm at any cost--they can come in many forms...dissociation, addictions, self-harm of various sorts, etc. In most approaches to psychotherapy, the goal would be to shut down the firefighters so that work to balance the managers and exiles could be underway, or to use the managers to control the firefighters so the exiles can be healed. In IFS, however, the firefighters are honored for the difficult and thankless jobs they take on. They are recognized as having good intentions for the system, even though their approach isn't particularly helpful.
IFS theory proposes that all of us have SELF energy that lies at the center of all these interacting parts...the exiles, managers, and firefighters. The approach to healing is to learn how to use the SELF energy to balance the system. The trick, especially for many of us here, is to FIND the self-energy that is buried under all the parts. To learn what it feels like to be
in SELF as opposed to being
in an exile part, a manager part, or a firefighter part. To access that SELF energy and be able to be
with parts. Because when we can do this, we can listen to parts' needs and provide them with what they need. In SELF, we can lead parts to become aware of one another's roles in the system, help them to work together to get what they need. That is why the organization that promotes this theory and approach to psychotherapy is called the Center for
Self-Leadership...because the SELF takes the lead in life rather than one or more of the parts.
