    Purpose: Behavioral interventions have been used with breast cancer survivors (BCS) in cancer pain management and post-treatment quality of life (QOL) studies. We studied the effects of an anti-inflammatory dietary intervention on QOL in BCS. Methods: One hundred fifty-three overweight and obese (body mass index [BMI] ≥ 25 kg/m2), early stage (0-III), English-speaking BCS who had completed all cancer treatment 2 or more months prior to enrollment were recruited into a two-arm randomized controlled trial with a 2 (group) by 3 (time) repeated measures design. Intervention components included six monthly food-preparation workshops and twelve motivational interviewing telephone calls. Endpoints included the Perceived Stress Scale (PSS), the Functional Assessment of Cancer Therapy–General (FACT-G) and Breast Cancer (FACT-B), and the Center for Epidemiologic Studies Depression Scale (CES-D). Repeated measures analysis using PROC MIXED in SAS version 9.4 was used. Results: On repeated measures analysis (intent to treat), there were no differences between groups on any of the QOL outcomes except the PSS total scores. These were significantly different in the intervention group (IG; n = 76) compared to control group (CG; n = 77), showing a main effect of assignment but no effect of time and no interaction effects. Conclusion: There was an impact on QOL as measured by the PSS between groups. The intervention reduced perceived stress at 6-month follow-up, but the effects dissipated by 12 months. Sources and stress and stress reduction should be a focus of future studies. Future research should also identify appropriate QOL measures that are sensitive to changes brought about by behavioral interventions.
