Abstract 2429: Social Support as a Moderator in the Relationship between Intrusive Thoughts and Psychological Symptoms among Spanish-speaking Latinas with Breast Cancer

Background: Intrusive thoughts are associated with higher levels of psychological symptoms and impaired quality of life in the year after breast cancer treatment. To our knowledge, no studies have examined social support as a potential moderator between intrusive thoughts about breast cancer and psychological symptoms among Latinas. This study aims to assess the moderating effects of different dimensions of social support on the association between intrusive thoughts and psychological symptoms among Spanish-speaking Latina breast cancer survivors. Methods: Analyses were performed using baseline data from a randomized control trial of a stress management intervention delivered to 151 Spanish-speaking Latinas with non-metastatic breast cancer. Survey measures on intrusive thoughts, four dimensions of social support (emotional/information, tangible, affectionate, and positive social interaction), and psychological symptoms (depression, anxiety, and somatization) were obtained at baseline via a structured survey. Information on age, time since diagnosis, breast cancer treatment, surgery type, breast cancer stage, history of depression and marital status was obtained via medical records review and served as covariates. Generalized linear models were used to investigate bivariate and multivariate associations and to explore moderation effects of the four dimensions of social support. Results: In the bivariate models, intrusive thoughts were associated with more depressive (β=0.024, p=0.0014), anxiety (β=0.047, p Citation Format: Cristian Escalera, Anna Maria Napoles, Jasmine Santoyo-Olsson, Carmen Ortiz.
