Personality encompasses a set of enduring traits and behavioral patterns that define how individuals think, feel, and interact, ultimately shaping their unique identities. The concept of personality has deep historical roots, deriving from the Latin term "persona," which means "mask." This term initially referred to the roles played by actors in ancient theater, signifying the different facets individuals display in various contexts.

Theoretical Approaches to Psychological Disorder

69
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

This summary is machine-generated.

Different personality disorder models show similar pathological trait profiles, suggesting they assess similar constructs despite distinct methods. This impacts personality disorder diagnosis within the Alternative Model of Personality Disorders (AMPD).

Area of Science:

  • Psychiatry
  • Clinical Psychology

Background:

  • The Alternative Model of Personality Disorders (AMPD) aims to refine personality disorder (PD) diagnosis.
  • Different theoretical models exist for classifying PDs, leading to questions about construct overlap.

Purpose of the Study:

  • To compare pathological trait profiles of PD prototypes from three distinct models.
  • To evaluate the convergence of these models within the AMPD framework.

Main Methods:

  • Trainee clinicians (N=329) rated patients using the Shedler-Westen Assessment Procedure (SWAP-II), DSM-5 hybrid model prototypes, and Psychodynamic Diagnostic Manual (PDM) prototypes.
  • Correlations between each PD prototype model and DSM-5 traits were analyzed.

Main Results:

  • Theoretically similar prototypes across SWAP-II, DSM-5, and PDM demonstrated correlations with several traits, exhibiting small-to-large effect sizes.
  • Generally, similar prototypes displayed comparable trait profiles, with some noted exceptions.

Conclusions:

  • The SWAP-II, DSM-5, and PDM prototype models appear to assess overlapping constructs in personality pathology.
  • Findings support the utility of these distinct models within the AMPD, despite theoretical differences, impacting PD diagnostic practices.
