Knowra Dimensional model of personality disorders Dimensional model of personality disorders An approach that describes personality pathology by its severity and characteristic traits rather than relying only on discrete diagnostic categories. It captures variation in how much pathology is present and how it is expressed.
Personality functioning : The capacities that support a coherent sense of self and effective relationships with other people. Impairment in identity, self-direction, empathy, and intimacy helps define disorder severity.
Personality disorder severity : The degree of impairment associated with personality pathology, ranging from limited dysfunction to severe disturbance. Severity provides a common measure of how much functioning is disrupted.
Alternative Model for Personality Disorders : The DSM-5 framework combining levels of personality functioning with pathological trait domains. It is the DSM’s principal dimensional alternative to conventional personality disorder categories.
Categorical model of personality disorders : An approach that classifies personality disorders into distinct diagnostic types. It treats diagnoses as separate categories rather than profiles along dimensions.
Personality trait : A relatively enduring pattern of thinking, feeling, or behaving that varies across people. Dimensional diagnosis describes pathology through continuous trait differences.
Maladaptive personality traits : Persistent patterns of cognition, emotion, and behavior associated with dysfunction or distress. Trait dimensions describe the characteristic form of a person’s pathology.
International Classification of Diseases 11th Revision : The World Health Organization’s international system for classifying diseases and health conditions. ICD-11 diagnoses personality disorder chiefly by severity, with optional trait qualifiers.
Personality disorder prototype matching : A diagnostic method that rates how closely a person resembles descriptions of disorder prototypes. Prototype matching offers graded judgments while retaining familiar disorder types.
Psychopathology : Patterns of psychological distress, dysfunction, or behavior studied as mental disorders. Personality pathology is one part of the broader study of mental disorder.
Trait domain : A broad grouping of related personality traits that captures a major pattern of individual differences. Domains organize narrower traits into interpretable profiles.
