Following recruitment by the PBRN, study personnel will call and confirm the PHQ-9 results with the SCID. If the patient passes the follow-up screening, the staff will arrange to travel to the patient's home. Study staff will obtain informed consent and perform baseline assessments including the Short Form-36, PHQ-9, Generalized Anxiety Disorder-7 (GAD-7), Medical Outcomes Study Social Support survey, and the ASA 24. The ASA 24 is an online dietary screener that measures energy intake over a 24 hour period. It is posted on the National Cancer Institute's website. Medication adherence and smoking levels will be measured by self report. Height, weight, waist circumference, and blood pressure will also be measured. With the exception of the SCID, each of these measures will be repeated at 3 month follow-up. The PHQ-9 will be completed monthly. Also, each month (three different time periods) participants will be asked to wear an armband accelerometer to measure energy expenditure over a 2 week period. The protocol gives details of the accelerometry procedures.
