Introduction: The aim of this research was to determine the relationship between perceived childhood STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT and adolescent STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT with identity status.Materials and Methods: This was a descriptive-analytic, cross sectional study. The sample was consisted of 106 females and 104 males’ high school students (15-17 years) in Torbat-e-Jam city, north east of Iran, which was selected through randomized and multistage sampling in 2008-2009. STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT to parents measured by STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT to Each Parents Scale and STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT in adolescents measured by Revised Adult STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT Scale and identity status measured by Extended Objective Measure of Ego Identity Status-2 Version Scale (EOM-EIS-2). Data were analyzed through chi square and liner regression analysis.Results: Findings show that secure, non secure-STYLE="font-STYLE:inherit;color:rgb(255,0,120);">AMBIVALENCE and non secure-avoidance STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT STYLEs had the most effect on the achieved identity, respectively. Non secure-avoidance, non secure-STYLE="font-STYLE:inherit;color:rgb(255,0,120);">AMBIVALENCE and secure STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT STYLEs had the most effect on the foreclosure identity, respectively too.Moreover non secure-STYLE="font-STYLE:inherit;color:rgb(255,0,120);">AMBIVALENCE and avoidance STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT STYLEs (positive relationship) and secure STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT STYLE (negative relationship) had the most effect on the moratorium identity respectively and Non secure-avoidance and secure STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT STYLEs (negative relationship) and STYLE="font-STYLE:inherit;color:rgb(255,0,120);">AMBIVALENCE STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT STYLE (positive relationship) had the most effect on the diffused identity respectively. Conclusion: Findings indicated that there are meaningful relationships between perceived childhood STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT STYLE and identity status and between different STYLE="font-STYLE:inherit;color:rgb(255,0,120);">ATTACHMENT STYLEs and identity status in high school students.
