I'm of the belief that internal family systems therapy can revolutionise the mental health, psychology, and sociological theories.
Its a relatively new form of depth psychotherapy. However, at the moment, the main issues, with its use as a mental health treatment are the following. I see there to be a lack of awareness about the modality and inaccessibility. The latter having twofold causes. Firstly, a lack of psychotherapists using the modality. Secondly, many people being priced out of accessing the psychotherapists that do practice the psychotherapy.
On a sociological level, I believe the understanding of the psyche that internal family systems brings enables us to better grasp our own operational dynamics. Therefore, it has the potential to allow us to better design causal systems towards preferential ends.
My current issue is I'm unaware of how to use/ develop my abilities to help maximise the likelihood that the potentials of the IFS model come about, and come about sooner rather than later.
I would like to add that CBT looks like "the therapy for everyone and everything" as is the only one that has shown to work with more mental health-related issues, and probably due to its effectiveness it is the most validated within the NHS since it benefits (also in an economical way).
We should start checking the relation between costs and benefices before trying to persuade the NHS.
