DATES

About

DATES (Decision Aid to Technologically Enhance Shared Decision Making) is an interactive decision aid website for colorectal cancer, designed to be used prior to a clinic visit to clarify each patient's preferences and promote shared decision-making. The website uses a unique interactive Preference Elicitation Tool, which helps patients determine the colorectal cancer screening test option that best matches their preferences.

Aims

Aim 1. To measure the impact of ColoWeb (CW) on patient uptake of colorectal cancer screening (CRCS).

Hypothesis 1: Patients in the Intervention Arm will have higher rates of CRCS adherence at the 6 month follow-up than those in the Control Arm.

Aim 2. To evaluate the impact of CW on patient determinants, patient preference, and patient intention before the patient-physician encounter.

Hypothesis 1: Patients in the Intervention Arm will show greater improvement from baseline in patient determinants (knowledge, attitude, subjective norm, perceived self-efficacy) compared to the Control Arm after the web intervention and before the patient-physician encounter.

Hypothesis 2: Patients in the Intervention Arm will be more likely to have a preference for a particular CRCS test option than those in the Control Arm after the web intervention and before the patient-physician encounter.

Hypothesis 3: Patients in the Intervention Arm will have higher intention to undergo CRCS than those in the Control Arm after the web intervention and before the patient-physician encounter.

Aim 3. To evaluate the impact of CW on shared decision-making, concordance, and patient intention during and after the patient-physician encounter.

Hypothesis 1: Patients in the Intervention Arm will experience a higher level of shared decision-making than those in the Control Arm.

Hypothesis 2: Higher rates of concordance will be reached between the patient's preferred CRCS test and the physician's recommended CRCS test in the Intervention Arm than those in the Control Arm.

Hypothesis 3: Patient's intention to undergo CRCS after the patient-physician encounter will be predicted by the study arm, degree of shared decision making, concordance, and interaction between shared decision making and concordance.

Participants

Participants are under age 50, scheduled for a doctor visit, do not have a current colorectal cancer screening, and have no history of colorectal cancer.
