The study population entirely consisted of over-18-years of age OCD patients referred to private consultation centers, and rural and urban healthcare centers in Rasht city during2014. The sample selected through purposive sampling consisted of 60 OCD patients who were randomly included in two experimental(ACT with and without OCD Family History) and two control (control with and without OCD Family History) groups. The experimental groups received eight ACT 45-minute sessions of Yale-Brown Obsessive Compulsive Scale was used to determine the severity of OCD. In addition, the brief version of WHO Quality of Life Scale was used to measure life quality and the clinical interview was used to investigate OCD family history. Multivariate analysis of variance test with repeated measures was used to examine the differences in pretest-posttest and follow-up scores.
