Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Colorectal cancer (CRC) remains the 3rd most common cancer in the US. Most CRCs are preventable, but screening participation remains suboptimal. Several factors have been associated with screening compliance, such as perception of CRC risk. Here we study the impact of telephone-based administration of the National Cancer Institute Colorectal Cancer Risk Assessment Tool (CCRAT) compared to usual care.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Screening Behavior: Differences in colorectal cancer screening completion rates between usual care (UC) and CCRAT
Time Frame: 12 months after intervention
Any CRC screening test completed including stool tests (FOBT (fecal occult blood test), FIT (immunochemical test for fecal blood), stool DNA test), colonoscopy, flexible sigmoidoscopy, double contrast barium enema, CT colonography (virtual colonoscopy)
12 months after intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Screening Behavior: Differences in colorectal cancer screening completion rates between usual care (UC) and CCRAT
Time Frame: 6 months after intervention
Any CRC screening test completed including stool tests (FOBT (fecal occult blood test), FIT (immunochemical test for fecal blood), stool DNA test), colonoscopy, flexible sigmoidoscopy, double contrast barium enema, CT colonography (virtual colonoscopy)
6 months after intervention
Change in intention to screen at 6 months and 12 months
Time Frame: Immediate after intervention, 6 months and 1 year after intervention
Differences in progressive behavioral stages of adoption from precontemplation to contemplation to preparation.
Immediate after intervention, 6 months and 1 year after intervention
Colorectal cancer screening rates at 12 months as a function of CCRAT score
Time Frame: 12 months after intervention
Screening completion at 12 months will be compared between the 3 tertiles of CCRAT score in the intervention group to determine whether there is any relationship between absolute CCRAT score and screening completion
12 months after intervention

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Risk perception: Health Belief Model Likert Scale
Time Frame: Immediate after intervention
Differences in perception of one's own risk of colorectal cancer ranging from "very unlikely" (minimum) to "very likely" (maximum), with "very unlikely" representing the most favorable outcome of perceived risk and "very likely" representing the most unfavorable outcome of perceived risk.
Immediate after intervention
Fear: Health Belief Model Likert Scale
Time Frame: Immediate after intervention
Presence of fear of discovering colorectal cancer on performing screening test ranging from "strongly disagree" (minimum) to "strongly agree" (maximum), with "strongly disagree" representing the most favorable outcome of fear and "strongly agree" representing the most unfavorable outcome of fear.
Immediate after intervention
