Background: Several studies have been conducted on the impact of acceptance-based and cognitive-behavioral therapy. But research comparing the efficacy of acceptance-based and commitment-based therapy and positive cognitive-behavioral therapy on pain self-efficacy in patients with chronic pain remains neglected. Aims: To compare the efficacy of acceptance and commitment based therapy and positive cognitive-behavioral therapy on pain self-efficacy in patients with chronic pain. Method: This study was a quasi-experimental study with a 3-month-old instructor with 3 witnesses. The statistical population consisted of all patients with chronic pain referred to Hazrat Rasool Akram Hospital in Tehran in summer of 2019. 45 patients were selected as the sample and randomly assigned to one of the two groups. Research tools are: Nicholas Pain Self-efficacy Questionnaire (2007), Acceptance and Commitment Therapy Intervention (Hayes et al., 2013) and Positive Cognitive-Behavioral Therapy (Ben Nink, 2014). Descriptive statistics and repeated measures analysis were used. Results: There was a significant difference between acceptance and commitment based therapy and positive cognitive-behavioral therapy with the control group in pain self-efficacy in patients with chronic pain (P< 0/001). But there was no significant difference between acceptance and commitment based therapy and positive cognitive-behavioral therapy in pain self-efficacy in patients with chronic pain (P< 0/05). Conclusions: Acceptance and commitment based therapy and positive cognitive-behavioral therapies are important in increasing my pain self-efficacy.
