Abstract: Limited research has examined psychological treatments for endometriosis-related chronic pain, despite its association with elevated disability, depression, and anxiety. Remotely delivered treatments have the potential to overcome barriers to access face-to-face psychological care, however, no studies have examined this format in endometriosis patients. The current study examined the efficacy and acceptability of an internet-delivered, psychological, pain management program for women with endometriosis-related pain. In this two-arm trial, 193 participants experiencing endometriosis-related pelvic pain were randomly assigned to the 8-week treatment or a waitlist control. The treatment was an adapted version of an established internet-delivered pain management program based on cognitive-behavior therapy principles. Relative to control, the treatment group reported significantly greater improvements (between groups Cohen's d ; average percentage change) in the primary outcomes of pain-related disability ( d = 0.35; 24%), depression ( d = 0.40; 17%), and anxiety ( d = 0.26; 17%) from pre- to post-treatment. Improvements were sustained at 3-month follow-up. No between-group difference was observed on the secondary outcome of average pain intensity ( d = 0.28; 17%, P = 0.054). High lesson completion and treatment satisfaction rates were observed. Mean clinician time per participant was 70 minutes (SD = 68). The current findings indicate the potential of a pain-focused psychological approach in supporting endometriosis-related pain, and the potential of the internet-delivered format in increasing access to care. Future research is needed to examine long-term outcomes and investigate factors associated with optimal treatment response.
