Evaluating Whether an Educational Website Called Current Together After Cancer (CTAC) Improves Follow-up Care for Colorectal Cancer Survivors

PRIMARY OBJECTIVE: I. To evaluate whether the patients randomized to the Current Together After Cancer (CTAC) intervention website compared to the CTAC control website have higher rates of guideline-concordant colorectal cancer (CRC) surveillance at 12 months after registration. SECONDARY OBJECTIVES: I. To assess patient reported knowledge about surveillance at 3 and 16 months post-patient registration. (Comparing CTAC intervention versus \[vs.\] control) II. To assess patient reported self-efficacy in management of surveillance 3 and 16 months post-patient registration using previously developed CRC screening self-efficacy measure. (Comparing CTAC intervention vs. control) III. To assess patient reported satisfaction with supporter engagement in surveillance 3 and 16 months post-patient registration. (Comparing CTAC intervention vs. control) EXPLORATORY OBJECTIVES: I. To assess the implementation of CTAC into clinic workflow, and to better understand barriers and facilitators to the delivery of the intervention arm using a mixed-methods approach. (For the process evaluation of the CTAC intervention) II. To explore the association between supporter participation in the assigned CTAC intervention at 3 months with receipt of CRC surveillance at 16 months. (Regarding supporter participation) III. To explore the association between supporter participation in the assigned CTAC intervention at 3 months with knowledge about surveillance; at 16 months. (Regarding supporter participation) IV. To explore the association of supporter participation in the assigned CTAC intervention at 3 months with self-efficacy in management of surveillance at 16 months. (Regarding supporter participation) V. To explore the association of supporter participation in the assigned CTAC intervention at 3 months. (Regarding supporter participation) OUTLINE: Patients are randomized to 1 of 2 groups and supporter participants are assigned to the arm to which their patient was randomized. GROUP 1: Patients and supporter participants receive access to the CTAC intervention website and may review the content as frequently as they like for up to 16 months on study. GROUP 2: Patients and supporter participants receive access to a general health education website and may review the content as frequently as they like for up to 16 months on study.
