Aim and Background: There is a relation between patients&#039; levels of physical functioning and their acceptance of chronic pain. However, this relation has not been examined amongst Iranian chronic pain patients. The purpose of this paper was to evaluate the relation between acceptance of chronic pain and physical disability. Methods and Materials: In a descriptive-correlational study, convenience sampling was used to select 245 chronic pain patients from pain clinics in Tehran, Iran during spring and summer of 2010. The participants completed the Chronic Pain Acceptance Questionnaire (CPAQ) and a demographic questionnaire. They also provided information about physical disability, pain intensity, and daily dysfunction. Data was analyzed using Pearson&#039;s correlation and multiple hierarchical regression models. Findings: There were significant relations between acceptance of pain and pain intensity and disability (P < 0.001). According to the regression model, acceptance of pain could predict a significant proportion of variance of disability scales (i.e. physical disability and daily dysfunction) (P < 0.0001). Therefore, it was a better predictor of disability compared to over pain intensity, gender, education, and pain duration. Conclusions: Chronic pain acceptance is an important factor in reducing the perceived disability in chronic pain patients. Therefore, acceptance-based treatment methods are helpful to decrease pain-related disability.

Aim and Background: Acceptance and commitment therapy can decrease psychological problems of the patients with rheumatoid arthritis. The purpose of the present study was to determine the effectiveness of acceptance and commitment therapy on the pain intensity perception in the patients with rheumatoid arthritis in Isfahan, Iran. Methods and Materials: This semi-experimental study was conducted using pretest-posttest and control group, with follow-up of the patients. Therefore, 30 women were randomly selected from those who referred to rheumatology centers in Isfahan and were diagnosed with rheumatoid arthritis by a rheumatologist and met other inclusion criteria. They were randomly assigned into experimental group and control group (15 individuals in each group) and followed up for two months. The data was collected using Mc Gill&rsquo;s pain intensity perception questionnaire which was completed by the participants. Then the experimental group received eight 90-minute sessions of acceptance commitment therapy intervention. The data was analyzed using repeated measures ANOVA. Findings: Acceptance and commitment therapy had significant effect on the pain intensity perception in patients with rheumatoid arthritis in experimental group (P < 0.50). This result was also observed after a one-month follow-up (P < 0.05). Conclusions: It can be concluded that acceptance and commitment therapy can be used as an intervention to decrease pain intensity perception in patients with rheumatoid arthritis.
