Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). 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
  • Psychometrics

Background:

  • Manic episodes are characterized by a complex array of symptoms.
  • Understanding the underlying structure of these symptoms is crucial for accurate diagnosis and treatment.

Purpose of the Study:

  • To determine the factor structure of manic symptoms as measured by the Scale for Manic States (SMS).

Main Methods:

  • Factor analysis of symptoms from 225 adults diagnosed with a manic episode.
  • Principal component analysis with oblimin rotation was applied to the Scale for Manic States data.

Main Results:

  • A six-factor solution was identified, explaining 59.29% of the variance in manic symptoms.
  • The identified factors include psychosis, irritability/aggression, dysphoria, accelerated thought stream, hedonia, and hyperactivity.

Conclusions:

  • A six-factor model effectively describes the clinical dimensions of mania in the studied sample.
  • Dysphoria emerged as a distinct factor within the structure of manic symptoms.
