Personality Disorders and Substance Use Disorders in a Sexual Context in the Man Having Sex With Other Men Population

Completed

• Conditions: Substance Use Disorders

• Registration Number: NCT03753737
• Lead Sponsor: Hospices Civils de Lyon

Brief Summary

Chemsex refers to the use of psychoactive drugs in a sexual context, mainly cathinones, GHB/GBL, methamphetamine, cocaine and ketamine. This can cause infectious or psychiatric complications, addictions, and often goes with high risk sexual behaviours. Recent studies have highlighted the relationship between personality disorders, substance use disorders and risky sexual behaviours. It is important to understand the factors associated with chemsex in order to offer adapted prevention and care plans.

The study hypothesis is that personality disorders, evaluated with the PDQ-4+ questionnaire, are more frequent among man having sex with other men with a substance use disorder linked to chemsex than among man having sex with other men who have never practised chemsex.
