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: Depression is one of the most common comorbidities of chronic pains such as chronic back pain and is the cause of limitations in the efficacy of cognitive-behavioral therapies (CBTs) in individuals with chronic pain. The existence of similar limitations and problems in cognitive-behavioral programs for the treatment of depression has caused a growing trend in the use of schema therapy by researchers in this regard. The aim of the present study was to compare the effectiveness of CBT and schema therapy on the reduction of depression in Iranian patients with chronic low back pain. Methods and Materials: The present clinical trial was conducted with a quasi-experimental design, pretest-posttest, fallow-up, and control group. In this study, 35 patients with chronic low back pain who were referred to pain specific clinics or neurosurgery clinics of Akhtar Hospital and Imam Hussein Hospital (AS) in Tehran, Iran, were selected through purposive sampling method. All patients completed the Chronic Pain Questionnaire, and Depression Subscale of the Depression Anxiety Stress Scales (DASS-21) in the pretest, posttest, and 2 months follow-up stages. Moreover, the schema therapy group completed the 90-Item Short Form of Young Schema Questionnaire (YSQ-SF) in addition to the mentioned questionnaires. Mixed effect regression model was used in SPSS software to investigate the efficacy of the two therapy methods on the reduction of depression in patients with chronic back pain.   Findings: Results showed that CBT (P < 0.005) and schema therapy (P < 0.033) had significant impacts on depression in patients with chronic low back pain in the 2 months follow-up stage. However, there was no significant difference between the two groups in terms of depression reduction in this stage (P < 0.519). Conclusions: Both CBT and schema therapy are effective in improving symptoms of depression in patients with chronic low back pain and can be used as appropriate treatment methods in patients with chronic pain and depression.

Aim and Background: Chronic pain is one of the most common and expensive medical problems. The aim of this study was to compare the effectiveness of emotion focused therapy and cognitive analytic therapy on anxiety sensitivity, pain catastrophizing, experiential avoidance and cognitive emotion regulation in patients with chronic pain and alexithymia.
Methods and Materials: This research was experiential study with pre, post-test and follow-up with control group. Among patients suffering from chronic in Isfahan, using available and voluntary sampling method, 36 patients that had top point in alexithymia questionnaire were selected and then  were assigned in two groups randomly (each group n=12). Members of first experimental group, received online emotion-focused group therapy and members of second experimental group received online cognitive-analytic group therapy. In this period control group didn’t received any intervention. Instruments were Karnfeskesʼs Cognitive Emotion Regulation Questionnaire (2001), Solivanʼs Pain Catastrophizing Scale (1995), Taylor and Koksʼes Anxiety Sensitinty Inventort (1998), Acceptance and Action Questionaire (2011) that were completed in 3 stages of pre, post-rest and follow up. Data were analyzed using repeated measure analysis.
Findings: Reults showed that the emotion focused therapy has been more effective than the cognitive analytic therapy in improving pain catastrophizing, experiential avoidance and the negative aspect of cognitive emotion regulation (P<0.05).
Conclusions: With respect to the effectiveness of these two therapeutic methods on the research variables, these two therapeutic methods can be sought so as to improve the conditions of the patients with chronic pain and alexithymia.

Aim and Background: Today, chronic pain is one of the main treatment challenges that affects many of the patient's daily activities. Various methods have been investigated to increase the quality of life in these patients. Acceptance and commitment therapy (ACT) is one of the promising interventions to improve quality of life in such patients. The aim of this study was to systematically review and meta-analysis the effectiveness of ACT on improving the quality of life of patients with chronic diseases in Iran.
Methods and Materials: In this study, the studies conducted in Persian language in the last decade (from 2011-03-21 to 2023-05-22) in internal databases (Sid, Magiran,Ganj, Irandoc, Civilica). The results were expressed in terms of Hedges effect size and the corresponding 95% confidence interval.
Findings: Out of 482 articles, 33 articles were used to conduct a meta-analysis of the effectiveness post-test compared to the control and 11 studies were used to investigate the effectiveness in the follow-up compared to the post-test. The effectiveness of ACT on post-test, the estimated effect size was 1.585 (CI=1.165 - 2.556 CI), and in the follow-up, the effect size was estimated to be 0.983 (CI=0.785 – 1.181).
Conclusions: Overall, the results showed that ACT improved the quality of life in patients with chronic diseases by 185% in the post-test and 98.3% in the follow-up period. Based on this, it can be said that this psychological therapy is a suitable method to improve the quality of life in these patients.
