Self-Report Tests of Personality01:22

Self-Report Tests of Personality

309
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 and Behavioral Sciences
  • Clinical Psychology
  • Neuroscience

Background:

  • Personality attributes are recognized as potential contributing factors in the development, persistence, and relapse of substance use disorders (SUD).
  • Specific traits like neuroticism, psychoticism, paranoia, anxiety, and antisocial personality traits have been implicated in SUD.
  • Understanding these links is crucial for developing targeted interventions.

Purpose of the Study:

  • To investigate and compare the personality profiles of individuals diagnosed with alcohol use disorder (AUD) and opioid use disorder (OUD).
  • To identify distinct personality characteristics associated with different types of substance use disorders.

Main Methods:

  • Recruited 928 participants aged 16-65, including 320 with AUD, 490 with OUD, and 118 healthy controls (HC).
  • Utilized the Clinical Profile Sheet and the Multiphasic Personality Questionnaire (MPQ) for data collection.
  • Participants met ICD-10 diagnostic criteria for substance dependence.

Main Results:

  • Significant differences in personality profiles were observed between individuals with OUD and AUD.
  • AUD patients exhibited higher MPQ scores for depression, mania, paranoia, and antisocial personality traits compared to OUD patients.
  • All MPQ subscales showed elevated scores in both AUD and OUD subjects relative to healthy controls.

Conclusions:

  • Personality factors significantly differentiate individuals with AUD and OUD.
  • Elevated scores across multiple MPQ subscales in SUD patients suggest a strong influence of personality on substance use patterns.
  • These findings highlight the importance of considering personality traits in the comprehensive management of substance use disorders.
