Aims: Chronic pain can change the body image in patients with musculoskeletal pain.  The purpose of this study was to investigate the effectiveness of compassion therapy and acceptance and commitment therapy on body image in patients with chronic musculoskeletal pain.
Method and Materials: This study is a Semi-Experimental research in nature with an unequal control group and pretest/post-test follow-up, which was conducted in 2023. The statistical population of this research included all patients with musculoskeletal pain in Tehran. The sample of this study included 45 patients with musculoskeletal pain whose scores were low on the body image scale, who were selected by a convenience sampling method. These people were divided into two groups: experimental and control, and one group of control (15 participants in each group). For the intervention group, eight 90minute sessions of compassion therapy, and for the control group, nine 90-minute sessions of acceptance and commitment therapy were held weekly Body image questionnaire was completed by all three groups in pre-test, post-test, and follow-up stages. The data were analyzed with SPSS software version 26.
Findings: The analysis of covariance with repeated measurements indicated there is no significant difference between experimental groups of compassion therapy and acceptance/commitment therapy (P<0.05), but both experimental groups were significantly different from the control group (P = 0.001). Conclusion: It seems that compassion therapy and acceptance/commitment therapy can improve body image in patients with chronic musculoskeletal pain. 

Aims: Fibromyalgia is a chronic pain disorder characterized by widespread musculoskeletal pain, fatigue, and tenderness in localized areas. The objective of this study is to investigate the effectiveness of Acceptance and Commitment Therapy (ACT) on pain anxiety, perfectionism, and aggression among women diagnosed with fibromyalgia.
Method and Materials: The current research design was semi-experimental with a pretest-post-test design with a control group. The statistical population of the research included women with fibromyalgia in Ardabil province of Iran in 2024. In this study, 34 women with fibromyalgia were selected through purposive sampling and divided into experimental (n=17) and control (n=17) groups. The experimental group participated in eight 90-minute sessions of ACT, while the control group did not undergo any intervention. Data collection involved administering the assessment Pain Anxiety Symptoms Scale (PASS), Perfectionism Inventory (PI), and Eysenck Aggression Questionnaires (EAQ). The collected data were then analyzed using multivariate analysis of covariance in SPSS-27.
Findings: The results showed that ACT significantly decreases cognitive (F=41.42, P=0.001, η2=0.61), avoidance (F=37.21, P=0.001, η2=0.59), fear (F=54.71, P=0.001, η2=0.68), physiological anxiety (F=46.72, P=0.001, η2=0.64), perfectionism (F=63.20, P0.001, η2=0.71), and aggression (F=52.11, P=0.001, η2=0.66) in women with fibromyalgia.
Conclusion: This research offers valuable insights into the effectiveness of ACT in enhancing psychological well-being among women diagnosed with fibromyalgia. Subsequent studies should delve deeper into the enduring effects of ACT and its viability within comprehensive treatment strategies for fibromyalgia, striving to deliver tailored and holistic care for individuals grappling with this complex condition
