This study identified two distinct personality profiles in cocaine abusers using the Minnesota Multiphasic Personality Inventory (MMPI). One profile suggests character disorder with narcissistic traits, while the other indicates concurrent psychiatric conditions.

Area of Science:

  • Psychology
  • Psychopathology
  • Substance Abuse Research

Background:

  • Understanding the psychological underpinnings of cocaine abuse is crucial for effective treatment.
  • Personality typologies can aid in tailoring interventions for individuals with substance use disorders.

Purpose of the Study:

  • To identify distinct personality profiles among individuals undergoing treatment for cocaine abuse.
  • To utilize hierarchical cluster analysis on Minnesota Multiphasic Personality Inventory (MMPI) data to uncover these typologies.

Main Methods:

  • Hierarchical cluster analysis was applied to the MMPI results of 104 cocaine abusers in treatment.
  • MMPI profiles were analyzed to identify distinct clusters based on specific scale elevations.

Main Results:

  • Two primary MMPI profile types emerged from the analysis.
  • Type I: Characterized by high scores on Psychopathic Deviate (Pd) and Hypochondriasis (Hyp), suggesting a rebellious, acting-out style with narcissistic traits.
  • Type II: Exhibited high scores across multiple scales (F, Sc, Dep, Pt, Pd, Pa), indicative of individuals with co-occurring psychiatric disorders alongside cocaine abuse.

Conclusions:

  • The MMPI can differentiate between distinct psychological profiles within the cocaine-abusing population.
  • These typologies offer insights into the diverse psychological characteristics of individuals with cocaine use disorder, informing treatment strategies.
  • Findings were compared with existing MMPI typological studies, highlighting both convergence and divergence in personality patterns.
