Preferential drug abuse: defenses and behavioral correlates

Area of Science:

• Psychology
• Psychiatry
• Neuroscience

Background:

• Understanding response styles and defensive patterns in substance use disorders is crucial for effective treatment.
• Polydrug abuse and sedative-hypnotic abuse represent distinct patterns of substance misuse with potentially different psychological underpinnings.

Purpose of the Study:

• To compare the psychological response styles and defensive patterns of polydrug abusers and sedative-hypnotic abusers with a healthy control group.
• To investigate the influence of frustration on these response styles.
• To examine the validity of the pharmacodynamic theory of drug abuse.

Main Methods:

• Rorschach inkblot test administration to assess psychological organization and defense mechanisms.
• Frustration-induction task using solvable and unsolvable anagrams to elicit behavioral responses.
• Thematic Apperception Test (TAT) card story selection and Profile of Mood States (POMS) questionnaire for mood assessment.

Main Results:

• Polydrug abusers showed significantly lower psychological organization, reduced ability to delay gratification, and increased restlessness/distractibility compared to sedative-hypnotic abusers and controls.
• Behavioral responses to unsolvable anagrams were consistent with the pharmacodynamic effects of the abused drugs in each respective group.
• Rorschach data revealed distinct differences in personality organization across the groups.

Conclusions:

• Polydrug abuse is associated with more severe deficits in psychological organization and impulse control.
• The findings support the pharmacodynamic theory, suggesting drug effects influence behavioral responses to stress.
• Results have implications for tailoring addiction treatment strategies to specific drug abuse patterns.
