Proof-of-Concept of an Integrated Yoga and Psychological Intervention in Mitigating Distress Among Diverse Women With Gynecologic, Gastrointestinal, and Thoracic Cancers

Abstract

Background: Fear of cancer recurrence (FCR), cancer-distress, depression, and anxiety are prevalent concerns among women with gynecologic and other understudied cancers, especially among women of color and lower socioeconomic status (SES). Evidence indicates that mind-body interventions are effective in reducing such distress. This study evaluates (1) proof-of-concept of an integrated group yoga and psychological intervention in alleviating distress among women with gynecologic, gastrointestinal, and thoracic cancers and (2) differences in efficacy across social and economic factors. Methods: One hundred twenty-five participants were enrolled in a 10-week, single-arm, integrated group intervention utilizing mindfulness meditation, psychotherapy skills, and yoga. They completed measures of FCR, cancer-distress, depression, and anxiety at baseline and following intervention. Mixed-linear models evaluated change in outcomes across the intervention and moderating effects of age, minority status, and SES among 51 participants with available data. Results: Reductions in total ( b = −2.06, P = .012) and somatic depressive symptoms ( b = −1.79, P = .002) and state anxiety ( b = −6.21, P = .005) were observed across the sample. Higher SES was associated with greater reductions in psychosocial distress related to FCR ( b = −0.74, P = .050), and in total (b = −1.06, P = .049) and affective depressive symptoms ( b = −0.76, P = .006). Women of color experienced greater declines in somatic symptoms compared to non-Hispanic White women ( b = −2.71, P = .031), with women of color experiencing lower SES exhibiting greatest reduction in these symptoms ( b = 1.73, P = .026). Conclusions: This study demonstrates proof-of-concept that an integrated psychological and yoga intervention may reduce depressive symptoms and state anxiety among women with gynecologic, gastrointestinal, and thoracic cancers, with racial and/or ethnic minority status and SES moderating some of these effects. Future research should examine intervention feasibility and acceptability among diverse women with cancer and evaluate efficacy using a randomized controlled trial design.
