Efforts to replace traditional approaches to the classification of mental disorders and the Diagnostic and Statistical Manual for Mental Disorders (DSM) have gained traction over the past several years. Researchers developing the Hierarchical Taxonomy of Psychopathology (HiTOP) approach have moved away from seeing mental disorders as discrete categories and instead cast them within a dimensional framework, seeing symptoms as occurring within a wider spectrum.
In a new article published in Current Directions in Psychological Science, HiTOP researchers Christopher Conway and Robert Krueger present evidence that this new approach puts mental health research, training, and treatment on a stronger scientific footing.
“Our position is that HiTOP provides substantial added value that makes the switch to a dimensional approach worthwhile for most researchers and clinicians. By portraying mental disorders in terms of dimensions, as opposed to categories, HiTOP preserves information about individual differences in mental health, enabling more reliable and valid measurement,” the authors write.
“By deconstructing categorical diagnoses into their constituent parts, it sheds light on the aspects of mental disorder that have the most predictive power. By taking an empirical stance toward classification, it ensures that diagnostic concepts will evolve with new data, not ossify like the many decades-old diagnoses that persist in DSM-5.”
HiTOP Dimensional Approach to Mental Disorders Superior to DSM Categories
The new HiTOP model takes a dimensional approach to mental disorders and may improve research, training, and treatments.

Abstract
Generations of psychologists have been taught that mental disorder can be carved into discrete categories, each qualitatively different from the others and from normality. This model is now outdated. A preponderance of evidence tells us that (a) individual differences in mental health versus illness are a matter of degree, not kind; and (b) broad mental health conditions (e.g., thought disorder) account for the tendency of narrower ones (e.g., hallucinations, delusions, paranoia) to co-occur. With these observations in mind, researchers are increasingly turning to an alternative diagnostic system, called the Hierarchical Taxonomy of Psychopathology (HiTOP), that describes the broad and specific components of mental disorder. It deconstructs traditional diagnostic categories, such as those listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM), and recasts them in terms of a profile of dimensions. Recent findings support the utility of this approach for mental health research and intervention efforts. Most importantly, HiTOP has the potential to put mental health research, training, and treatment on a much sounder scientific footing.
