Quick takeaways
- Polyvagal Theory, although criticized, still lacks enough evidence to be definitively debunked or replaced by alternative theories.
- Individual experiences may vary, and it's crucial to consider other explanations and interventions for specific situations.
- Finding a framework that resonates with individuals and provides understanding is essential, regardless of the strength of evidence supporting it.
Deep dives
Substantive evidence against PBT
Although there are some challenges and criticisms of polyvagal theory (PBT), there isn't a preponderance of evidence against it. Some studies have attempted to debunk or refute it, but there is still ongoing research and debate on its validity.
Alternative theories
There are alternative theories to PBT, such as the neuro-visceral integration model, the biological-behavioral model, the resonance-frequency model, and the psychophysiological-coherence model. While these theories offer different perspectives, none of them have enough evidence to definitively replace PBT as the main explanatory framework.
Potential harm of using PBT
While individual experiences with PBT may vary, there is a concern that relying solely on PBT without seeing improvement in functioning could be problematic. It's essential to consider other explanations and interventions that might better help individuals in their specific situations.
The importance of making meaning
Whether or not PBT is supported by strong evidence, the crucial aspect is finding a framework that helps individuals make sense of their experiences. Our interpretations and meanings of events shape our understanding and guide our actions. If PBT resonates and provides understanding for individuals, it may still hold value in that context.
The Power of Self-Diagnosis and Creating Coherence
Self-diagnosis based on advanced screeners can help create coherence and make meaning out of personal experiences. It provides a macro story that holds individual microstories together, allowing individuals to feel a sense of autonomy. By understanding their window of tolerance and connecting it to their past and present experiences, individuals can widen their window and have a better understanding of their reactions. This knowledge helps to form a coherent story that doesn't blame oneself or others but acknowledges the impact of biology and trauma. Believing in this story allows individuals to make changes and respond differently to challenging situations.
The Importance of Cultural Beliefs and Myths in Healing
Cultural beliefs and myths play a crucial role in healing and therapy. The degree of fit between a therapist's explanation of illness and the client's understanding of suffering is essential. Just as survivors of the Pol Pot regime in Cambodia used culturally specific beliefs and rituals to navigate their trauma, individuals need explanations that align with their cultural beliefs and provide autonomy. Therapy should involve a confiding relationship, a different context, a plausible explanation for the illness, and a ritual or intervention believed to be effective. The power of myths and stories lies in their ability to grant a greater sense of autonomy over one's life and offer a path to healing and change.
Polyvagal Theory is everywhere these days.
Psychologists talk about it; parenting coaches talk about it; if you’re in
the mental health field you’re probably referring to polyvagal theory in some way. So one would assume that there’s lots of evidence for it, right? Well, maybe. Maybe not.
In this episode I dig into the foundational principles of Polyvagal Theory and find that there's a lot less evidence supporting it than you might think, given how many places it's used.
So what's going on? Is it legit? Should we be using a different theory to understand our experience instead?
But all may not be lost! Maybe there are aspects of the theory that we can still use...the episode suggests a path forward on this.
