About this trial
The objective of the pilot RCT is to evaluate the feasibility and acceptability of a Tai Chi intervention "TaiChi4Joint" vs. an HE AC group for relieving AIIA in women with hormone receptor positive stage I-III BCa. The investigators will pilot test our data collection for mechanism measures via three innovatively integrated biobehavioral pathways.

Secondary outcomes
Client Satisfaction Questionnaire Score
Participant reported satisfaction with the intervention measured using the Client Satisfaction Questionnaire. Acceptability will be 1) 80% of participants report a mean score of 4 or higher on participants' responses to study acceptability items on the Client Satisfaction Questionnaire. Client Satisfaction Questionnaire - 8 Item Version (CSQ-8) is a standardized measure of global satisfaction with services. It consists of 8 items, each rated on a 4-point Likert scale, with responses summed to yield a total score ranging from 8 (minimum) to 32 (maximum). Higher scores indicate a better outcome, reflecting greater client satisfaction with the services received.
Patient Perceived Credibility of the Intervention
Primary benchmark for Credibility will be 2) a mean score of 4 or higher on participants 'responses to study items from the Credibility/Expectancy Questionnaire. 3) Chi-square tests will compare feasibility metrics by White vs. AA patients. Quantitative acceptability ratings will be summarized. The Credibility/Expectancy Questionnaire (CEQ) is a measure of treatment credibility and expectancy for improvement. It includes a Credibility subscale (3 items scored on a 1-9 scale) with total scores ranging from 3 (minimum) to 27 (maximum), and an Expectancy subscale (2 items scored on a 0-100 scale) with scores typically averaged to yield a range from 0 (minimum) to 100 (maximum). For both subscales, higher scores indicate a better outcome, reflecting greater perceived credibility of the intervention and stronger expectations that the treatment will be effective.
