The objective of the proposed study, using an experimental, two-group (n = 30 couples in each group) repeated measures design, will be to pilot test the effects of the PaTH Intervention versus a usual care group in improving the following outcomes: a) physical activity and healthy eating behaviors, b) functional capacity; c) quality of life (physical, psychological, and relational); and d) risk level for heart disease. The primary variables will be change in outcomes from baseline to 3 and 6 month time points in both the coronary artery bypass graft (CABG) patient and his/her partner.
