Tailored Web-Based Intervention for Cancer Patients and Family Caregivers

Inclusion Criteria: * cancer patients with confirmed diagnosis of breast, colorectal, lung or prostate cancer * early stage (I or II, diagnosed within past 2 to 12 months) OR advanced stage (III or IV, diagnosed or progressed within past 2 to 12 months) * age 18 or older * physically/mentally able to participate * speak/read/write English * have access to internet at home * have a family caregiver willing to participate * family caregivers must be age 18 or older, physically/mentally able to participate, able to speak/read/write English, identified by the patient as his or her primarily family caregiver, and have access to and willing to use the internet. "Family caregiver" is defined as the family member or significant other identified by the patient as his or her primary source of emotional or physical support during the current cancer experience and confirmed by the designated individual. Exclusion Criteria: * Family caregivers will be excluded from the study if they themselves have been diagnosed with cancer in the previous year or are receiving active treatment for cancer. This criteria was established so all dyads are managing effects of cancer in patients, not the family caregivers.
