The aim of this study was to investigate the relationship between attachment and identification with mate selection criteria for students. Methods The study was correlational. The research sample consisted of 149 girls and 151 boys that random sampling of students in dormitories of the Persian Gulf, was in the academic year 2014-2015. Data collection tools, questionnaires for assessing identity ISI-6G 40-item questionnaire Hazan and Shaver 15 items (1987) 22-item questionnaire to measure the interest and welfare (1387) to assess the criteria for mate selection. The results showed that avoidant attachment style and content to the criteria for mate selection process and there is a significant negative relationship. As well as the criteria for mate selection process with secure attachment style and content and there is a significant positive relationship. Anxious attachment between mate selection criteria for content and there is a significant negative relationship. Between normative style, genre and style commitment mate selection criteria process information and content and there is a significant positive relationship. But the light confused with mate selection criteria and process content Nyamd.ntayj multivariate regression analysis showed significant correlation between avoidant attachment style (standard beta coefficient= -0.27 and P<0.001) is negative, secure attachment style (standard rate beta= 0.23 and P<0.001), and light-normative (standardized coefficient beta= 0.21 and P<0.01) is a positive process of mate selection criteria can not predict male students. Style identity data (standardized coefficient beta= 0.20 and P<0.01), and secure attachment (standard coefficient beta= 0.19 and P<0.05), the positive content of mate selection criteria for female students was predicted. The female students only secure attachment (standard coefficient beta= 0.27 and P<0.01), the process of mate selection criteria positively predict. Light normative (standardized coefficien
