They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Area of Science:

  • Psychiatry
  • Clinical Psychology

Background:

  • Personality disorders (PD) are prevalent in psychiatric populations.
  • Understanding the frequency and characteristics of PD subtypes is crucial for effective treatment.

Purpose of the Study:

  • To determine the frequency, socio-demographics, and comorbidity of ICD-10 personality disorders in psychiatric inpatients.
  • To evaluate the validity of subdividing emotionally unstable PD into impulsive and borderline subtypes.

Main Methods:

  • Analysis of routine data from all psychiatric hospitalizations in the Canton of Zurich between 1998 and 2002.
  • Comparison of socio-demographic factors and comorbidities between impulsive and borderline PD subtypes.

Main Results:

  • Personality disorders were diagnosed in 10.2% of inpatients.
  • Emotionally unstable PD accounted for 54.5% of all PD diagnoses.
  • Significant differences in sex, age, employment, and comorbidity were found between impulsive and borderline subtypes.

Conclusions:

  • Emotionally unstable PD is the most frequent PD in clinical settings.
  • The differentiation of emotionally unstable PD into impulsive and borderline subtypes is clinically justified.
