The descriptive-correlation method is used. The statistical population of this study was all married men who applied for cosmetic surgery referred to relevant clinics and non-applicant married men in Yazd. According to this, a sample of 200 people, including 100 applicants and 100 non- applicant who were selected by available sampling. Then, Early maladaptive Schemas scale (Yang, 1998) and Bagarozzi's marital intimacy questionnaire (2001) were distributed among the subjects and after completing the questionnaires, the results were analyzed through logistic and Pearson correlation calculation. There is a significant relationship between different domains of early maladaptive schemas and intimacy of couples; Also, The findings showed that early maladaptive schemas and marital intimacy predict the tendency for cosmetic surgery in married men. The results of multiple regression analysis showed that the three maladaptive schemas of autonomy and dysfunctional functioning, acceptance, cut and rejection, as well as the interference component in social performance of body image, respectively, had the highest share in predicting the tendency for cosmetic surgery, respectively. The schemas in a person's life act as lenses that shape the interpretation, selection, and evaluation of one's experiences. Considering the role of early maladaptive schemas and marital intimacy in predicting the tendency to cosmetic surgery in this study, it is suggested to provide psychological treatments, especially schema therapy and couple therapy, before cosmetic surgery.
