The researchers are doing this study to compare two different types of group therapy and find out whether they are effective approaches for helping breast cancer survivors manage joint pain caused by aromatase inhibitors (AI). This type of joint pain is called AI-associated arthralgia, or AIA, and it is common in people taking AIs. AIA and its associated symptoms can make some people decide to stop taking their medication. The study will look at the effects of two different types of group therapy on participants' cancer-related symptoms (such as pain, fatigue, and anxiety), their ability to continue taking AIs on a regular schedule, and their quality of life. We will measure participants' quality of life by having them fill out questionnaires.
Both groups will have 2-hour group therapy sessions once a week, over the course of 8 weeks. During the sessions, you will be in a group of 6-10 participants, who may be a mixture of patients from both MSK and University of California San Diego (UCSD).

Pain Interference
Pain interference will be assessed using the 7-item Pain Interference subscale from the Brief Pain Inventory Short Form (BPI-SF). Each item is rated on a scale from 0 ("does not interfere") to 10 ("completely interferes"), with higher scores indicating worse interference. The BPI is a widely used, reliable, valid, and responsive tool for measuring pain (Cronbach's α 0.77-0.91). The Pain Interference subscale will be administered at baseline, weekly during the 8-week intervention, and at weeks 12 and 24. Completing the survey requires approximately 1 minute.
Pain Severity
Pain Severity will be assessed using the 4-item Pain Severity subscale from the Brief Pain Inventory Short Form (BPI-SF). Each item is rated on a scale from 0 (no pain) to 10 (pain as bad as you can imagine), with higher scores indicating worse pain. Pain Severity will be administered at baseline, week 8, week 12, and week 24. Completing the survey requires approximately 1 minute.
Pain Catastrophizing
Pain Catastrophizing will be assessed using a 13-item Pain Catastrophizing Scale (PCS) measuring the negative cognitive-emotional response to pain. Patients rate the degree to which they experience thoughts and feelings that may be associated with pain on a 0 (not at all) to 4 (all the time) scale. The PCS yields a total score and three subscales scores assessing rumination, magnification, and helplessness. It will be administered at baseline, week 8, week 12, and week 24. Completing the survey requires approximately 4 minutes.
Patient Global Impression of Change
Patient Global Impression of Change (PGI-C) will be assessed on a one-item scale assessing a clinically important change from the patient's perspective. Patients respond to "How would you describe your pain since you began the treatment?" on a 7-point scale ranging from "very much worse" to "very much improved." Subjects reporting "much improved" and "very much improved" will be classified as responders. The PGI-C will be administered at week 8, week 12, and week 24. Completing the survey requires approximately 1 minute.
Anxiety/Depression
Anxiety and Depression will be assessed on a 14-item Hospital Anxiety and Depression Scale (HADS) assessing anxiety (7 items) and depression (7 items) on a 4-point scale (0-3). Scores range from 0-21, with higher scores indicating higher symptomatology. Established cutoffs classify symptoms as not significant (0-7), subclinical (8-10), or clinically significant (11-21). The HADS will be administered at baseline, week 8, week 12, and week 24. Completing the survey requires approximately 4 minutes.
