ABSTRACT
The purpose of this study, was to determine the efficacy of cognitive - behavioral group therapy in health - related quality of life, in irritable bowel syndrome [IBS] patients. 32 IBS patients who received this diagnosis, according to the Rome II criteria, were selected and assigned randomly to either the experimental or the control group with 16 IBS patients in each group. The experimental group received 8 weekly CBGT sessions in the department of gastroentology in a general Hospital in the central city. The Quality of Life Inventory [QOL] and Beck Depression Inventory [BDI] were used as the pretest, post-test and follow-up. The follow-up tests were conducted two months after the last intervention session. Results of Multivariate Analysis of Covariance [MANCOVA] showed that the mean scores of health - related quality of life and depression, in the experimental group, was significantly lower than the control group in post-test[P=0.004, P=0.023],but there wasn't significant difference in follow-up. Results also showed that the scores of health anxiety in experimental group was significantly lower than the control group in post-test [P=0.007] and follow - up [P=0.02]. CBGT could be an effective and selective psychotherapy to improve HRQOL and degree depression and health anxiety of IBS patients, but in this therapy, in addition to automatic thoughts, we should also consider to core beliefs and underlying assumptions to enhancement the efficacy of intervention
ABSTRACT
Multidimensional and complex nature of obsessive compulsive disorder [OCD] requires assessment and usage of modern treatments. This study was planned to investigate the effectiveness of Wells' metacognitive model on thought fusion symptoms in patients with OCD as an important aspect of metacognitive beliefs. This semi-experimental study was conducted with pretest-posttest and follow-up design, using control group. From all OCD patients visited in psychology clinics in Shiraz city, south western part of Iran in 2008, 24 patients were selected through the objective sampling method and randomly divided in two equal experimental and control groups. Experimental group experienced 8 weeks of Wells' metacognitive therapy, while control group were just followed. Thought fusion instrument [TFI] was used in pretest, posttest and 2-month follow-up as the study instrument. Data were analyzed by descriptive indices and multivariate analysis of covariance, using SPSS software. The experimental group showed significant decreases in thought fusion general score and its triple items in post-test and follow-up, compared with control group [P<0.001]. Wells' metacognitive model is beneficial in decreasing thought fusion in OCD patients
