Objective: This study aims to compare the effectiveness of Family Therapy Based on metacognitive therapy and Mindfulness on Marital Intimacy among divorce applicant clients. Method: The design of the study is an experimental research with pretest and posttest with a control group. The study population includes all divorce applicant clients referring to well-being and counseling agencies of Sanandaj city, located in Kurdistan province, in 2011. Sixty-six clients were selected from among the population using random sampling and then, they were divided into three groups of 22 using random assignment method. The independent variable of marital intimacy was measured among divorce applicant clients (pretest) using the marital intimacy questionnaire (Oliya et al., 2006) and after intervening two experimental groups for 8 sessions, the dependent variable was again calculated for three groups (posttest). Multivariate analysis of covariance was used to examine the effect of pretest and treatment.
