TALK TOPIC
Why DSM mental health diagnoses do and do not exist…
Mental health diagnoses, as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM), lack strong scientific validity. A key issue is that while the individual components (or phenotypes) of traditional diagnostic categories are often scientifically valid, the way these components have been grouped into diagnostic categories is not. As a result, the U.S. National Institute of Mental Health (NIMH) – the world’s largest funder of mental health research in the world – ceased funding research based on DSM categories in 2013, instead prioritising research into the individual phenotypes. Other major scientific bodies have since followed suit.
A significant challenge is that traditional diagnostic categories are deeply embedded in healthcare systems and societal understanding, including here in Aotearoa/New Zealand. Clinicians often depend on them to access funding for care for their patients and clients. In turn, individuals rely on these diagnoses to make sense of their mental health, and guide their healthcare. People additionally face much anti-scientific misinformation and disinformation, especially online, causing further confusion.
This presentation will outline criticisms of current diagnostic models that are supported by broad scientific consensus, and how the field is responding constructively. It will help attendees distinguish between this helpful scientific skepticism and progress, versus unhelpful anti-scientific cynicism or conspiracy theories. The talk will be aimed at an educated lay audience with an interest in mental health and wellbeing.
