Abstract

Depression is one of the common disabling and recurring psychological disorders that causes obvious changes in the individual’s different biological, cognitive, nervous and emotional functions .The aim of the present study was to compare effectiveness of cognitive behavioral therapy and acceptance and commitment therapy for rumination, cognitive flexibility, resilience and perceived stress among the women suffering from depression in Andimeshk city. Depression is also considered as the second most common cognitive disorder and therefore it has attracted the attention of many researchers around the world. Among the existing physical and mental diseases, depression is considered one of the most important global issues and problems, which according to the definition of the World Health Organization is the most important mood disorders that include loss of interest, feelings of guilt and worthlessness, sleep and appetite disorders, It is accompanied by a decrease in energy, poor concentration, and a decrease in the patient's mood. Depression is also a common, costly and debilitating disease that imposes a heavy burden on global societies.

Method
The statistical population included all women referred to psychiatric clinics. 45 patients were randomly assigned into three groups (two experimental groups and one control group). Measuring research variables with the help of Nolen-Hoeksema and Morrow’s rumination questionnaire (1991), Dennis and Vanderwaal's (2010) cognitive flexibility, Connor and Davidson's (2003) resilience, and Cohen et al.'s (1983) perceived stress questionnaire were used. At first, after obtaining the necessary permits and coordination with the psychiatric clinics of the city, all women referred to the psychiatric clinics who were suspected of symptoms of depression were screened by a psychiatrist. The initial diagnosis was made by a psychiatrist, and then, to make the diagnosis more certain, the clinical interview of SKID 5 was conducted by the researcher. According to the criteria for entering the research, 30 patients who were willing to cooperate in the research were randomly assigned into two groups (an experimental group of 15 people each and a control group of 15 people).

Results
Analysis was done using analysis of covariance, two-way variance analysis and repeated measures and Ben Ferroni’s follow up test. The results indicated that there was a significant difference between effectiveness of acceptance and commitment therapy compared to cognitive behavioral therapy for rumination; No difference was observed in the effectiveness of the two approaches for cognitive flexibility and perceived stress. The results of the present study indicated that there was no significant difference in the effectiveness of both treatment methods on the three variables of cognitive flexibility, resilience and perceived stress. There was a difference between the two treatments only in the variable of rumination, so that the effectiveness of the treatment based on acceptance and commitment was confirmed. Regarding cognitive behavioral therapy, no evidence was found to confirm its effectiveness.

Discussion
Both approaches can be considered as effective methods for reduction of the symptoms of depression; however it is necessary to evaluate and compare effectiveness of the two methods for depression related variables in different groups as well.
