Aim: Pain is the most common mental pressure facing humans and one of the most common complaints among fibromyalgia patients. The present study aimed to investigate the effec-tiveness of Positive Mindfulness Therapy (PMT) and Emotion-Focused Cognitive-Behavioral Therapy (EFCBT) in improving pain perception and sleep quality in patients with fibromy-algia. Method and Instruments: This study is a quasi-experimental research in which ۶۰ referees  who visiting Red Cross affiliated physiotherapy clinics in Tehran in ۲۰۲۰ were selected by convenience sampling and randomly divided into two experimental groups (positive mind-fulness therapy and emotion-focused cognitive-behavioral therapy) and a control group (N= ۲۰ individuals per each group). The research instruments included the Pittsburgh Sleep Quality Index (PSQI) and the McGill Pain Questionnaire (MPQ). Data were analyzed using SPSS software version ۲۰. Findings: The results showed that PMT produced significant improvements in pain percep-tion (P< ۰.۰۰۱) and sleep quality (P= ۰.۰۱۳) in the patients compared to the control group. Furthermore, EFCBT was effective in improving pain perception (P< ۰.۰۰۱) and sleep quality (P = ۰.۰۱۵) in fibromyalgia patients. The results did not imply a significant difference be-tween the two treatment interventions. Conclusions: Using PMT and EFCBT are effective in attenuating pain perception and improv-ing sleep quality in fibromyalgia patients.
