The objective of the study is to develop and test the feasibility, acceptability, and initial efficacy of a novel couples-based behavioral weight and symptom management intervention for obese breast cancer survivors and their partners. The proposed project consists of two phases. Phase I will include intervention development and refinement. Intervention development will be guided by the research team's prior work, the interdependence model of communal coping and behavior change, and information obtained from couples participating in focus groups. The intervention protocol will then be tested with 5 couples to assist with refinement of intervention content. During phase II, the feasibility, acceptability and initial efficacy of the intervention will be examined. Obese breast cancer survivors in the three years following treatment and their overweight or obese partners will receive 6 weekly and 6 biweekly sessions for a total of 12 sessions spaced across approximately 5 months. The intervention will be provided in a couples-based format where each couple will meet separately with the therapist. Couples will be assessed at pre-, post-, and 3-months post-treatment. Study outcomes will be weight, symptoms (i.e., pain, fatigue, distress), eating behavior, and physical activity. Exploratory outcomes examine biomarkers (i.e., insulin, IL-6, IL-8, TNF-alpha, adiponectin) associated with health outcomes for cancer survivors and their partners. It is hypothesized that the intervention will be feasible (i.e., completed sessions), and participants will find the intervention acceptable as assessed by a measure of treatment acceptability. It is also hypothesized that participants will evidence decreased weight and improvements in symptoms (i.e., pain, fatigue, distress), eating behavior, and physical activity, and their change in weight will covary with change in symptoms, eating behavior, and daily physical activity. Finally, it is hypothesized that participants with greater weight loss will evidence improved functioning in insulin, IL-6, IL-8, TNF-α, adiponectin, and heart rate.

| Couples-Based Behavioral Weight and Symptom Management | Behavioral | Investigators anticipate that the intervention developed in phase I will consist of a total of 12 sessions 90 minutes in length (18 therapy hours) spaced across approximately 5 months. Sessions are spaced to provide participants sufficient time to complete home practice exercises and adequately examine change in weight and maintenance of weight loss. Sessions will be conducted individually for each day. The first 6 sessions will occur weekly and the final 6 sessions will occur biweekly. |

| Change in Eating Behavior | Participants will also be asked to complete the Dietary Instrument for Nutrition Education (DINE). The DINE is a brief assessment of the amount of fat and dietary fiber in an individual's usual diet. Participants are provided with a list of food items and asked about the frequency with which they have eaten the items per week when considering the last month. | baseline , post-treatment (approximately 18-20 weeks), 3 months post-treatment (approximately 30-32 weeks) |
