Abstract

BACKGROUND: Studies over the past two decades have shown that various personality traits of substance-dependent men measure differently than compared to normal individuals. However fewer studies have addressed the role of identity as an influential factor in the onset and continuation of drug dependency.

METHODS: The objective of this study was to compare the Big Five personality factors and identity styles in methamphetamine dependent women and non-user group. Forty eight methamphetamine dependent women under treatment in Welfare Organization’s residential centers filled out the NEO Five-Factor Inventory (NEO-FFI) and the Berzonsky’s Identity Style Inventory. They were compared with 48 non-dependent women who were matched in terms of age, education, marital status, and occupation. Data was analyzed with t student test. Statistical analyses were performed using the SPSS V.16 software. Differences were considered significant at P<0.05.

RESULTS: Results found that methamphetamine dependent woman had significantly higher levels of neuroticism and lower levels of conscientiousness, agreeableness and openness to experience compared to normative sample of female respondents .In addition, mean scores of diffuse/avoidant identity style in methamphetamine user women was significantly higher than non-user group. This is while non-user women had a significantly higher mean in normative identity style.

CONCLUSION: Identity styles along with personality traits can be a key role in drug use in women in this study. Therefore, enhancing understanding about the role of identity can be helpful in treatment programs especially in harm reduction approaches.
