Effectiveness of the CHESS eHealth Cancer Support Intervention in Population-based Care

无干预：Usual Care

A group using a Basic ICCS provided by KPNW

实验性的：Intervention

A group using an enhanced ICCS with KPNW web resources and the Comprehensive Health Enhancement Support System (CHESS.)

行为的：Enhanced ICCS with KPNW web resources and the Comprehensive Health Enhancement Support System (CHESS.)

Half of the participating women will be randomly assigned to use an informative but static website (Basic ICCS), and half will be offered a fully interactive CHESS (Enhanced ICCS + the Basic ICCS). Study outcome data will be gathered from patients, clinicians, and the healthcare system (i.e., from the electronic medical record: EMR) for at least 8 months after study entry. We propose that the Enhanced ICCS relative to the Basic ICCS, will:

• Improve patients' sense of cancer information competence (perceived ability to obtain and use relevant information)
• Reduce patients' negative affect and increase their emotional well being
• Improve patients' sense of social support
• Improve patients' health self-efficacy
• Improve patients' ratings of experience with cancer specialty care services
• Improve patients' health related quality of life (HRQL)
• Improve clinicians' ratings of quality of patient contacts
• Reduce healthcare utilization and costs (obtained via the EMR)

Amount of ICCS use and women's ratings of cancer information competence, perceived social support, and emotional well being. Secondary outcomes will include healthcare utilization, cost-effectiveness, and clinician ratings of healthcare visits.
