Connecting quantitatively derived personality-psychopathology models and neuroscience

Area of Science:

• Neuroscience
• Psychology
• Psychopathology

Background:

• Traditionally, personality is viewed as dimensions (habitual thoughts, feelings, behaviors), while psychopathology is seen as categories of disorder.
• Empirical evidence indicates psychopathology aligns more with dimensions, often similar to personality dimensions, rather than distinct categories.
• This special issue explores reconceptualizing personality and psychopathology through interconnected dimensions.

Purpose of the Study:

• To integrate personality and psychopathology research through a dimensional lens.
• To explore the utility of neuroscientific inquiry within an integrative framework.
• To provide background and summarize contributions on the personality-psychopathology-neuroscience interface.

Main Methods:

• Review and synthesis of research presented in the special issue of Personality Neuroscience.
• Conceptual analysis of dimensional versus categorical models of personality and psychopathology.
• Exploration of neuroscientific approaches to understanding integrated personality-psychopathology dimensions.

Main Results:

• Psychopathology does not form discrete categories but rather delineates dimensions similar to personality.
• An integrative, dimensional model of personality and psychopathology is supported by empirical literature.
• Neuroscientific inquiry is valuable from this integrated perspective.

Conclusions:

• Reconceptualizing personality and psychopathology in terms of connected dimensions is crucial.
• Integrative, quantitatively derived models offer a promising avenue for advancing neurobiological understanding.
• Continued research is needed to refine these dimensional models and their neurobiological underpinnings.
