Methamphetamine-dependent women exhibit distinct personality traits, including higher neuroticism and lower conscientiousness. Their diffuse/avoidant identity styles are more prevalent, suggesting identity plays a role in substance use.
Area of Science:
- Psychology
- Neuroscience
- Addiction Studies
Background:
- Research indicates personality differences in substance-dependent men compared to non-dependent individuals.
- Fewer studies have explored the role of identity in drug dependency onset and continuation.
Purpose of the Study:
- To compare Big Five personality factors and identity styles between methamphetamine-dependent women and a non-user control group.
Main Methods:
- Forty-eight methamphetamine-dependent women and 48 matched non-dependent women completed the NEO Five-Factor Inventory and Berzonsky's Identity Style Inventory.
- Data were analyzed using independent samples t-tests with SPSS V.16.
- Statistical significance was set at P<0.05.
Main Results:
- Methamphetamine-dependent women showed significantly higher neuroticism and lower conscientiousness, agreeableness, and openness to experience.
- Users had higher diffuse/avoidant identity styles, while non-users scored higher in normative identity style.
Conclusions:
- Identity styles and personality traits are significant factors in women's drug use.
- Understanding identity's role can enhance treatment and harm reduction strategies for substance use disorders.
