Decision-aid on Breast Cancer Screening

March 1, 2021 updated by: Mario Negri Institute for Pharmacological Research

New Invited Women to Breast Cancer Screening: a Multi-centre, Longitudinal, Controlled, Randomised Study on a Decision-aid to Support Informed Choice

The present study aim to assess the effect of an interactive web decision aid on informed choice - measured via knowledge, attitudes and intentions concerning breast cancer screening - comparing the decision aid with a standard information provided via web.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Breast cancer is the most common cancer in women. In Italy, women are invited to a population-based mammography screening programme for the first time at the age of 45 or 50 years. Results from randomised controlled trials, observational studies, and systematic reviews continuously fuel the debate on the balance on benefits (reducing breast cancer mortality) and harms (overdiagnosis, overtreatment) of mammography screening. Physicians, policy makers, as well as laypeople or patient associations agree on the need to inform women about the potential benefits and harms in order to allow an aware decision process. Decision aids are an effective way to support lay people in their decisions about health.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
1001

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.

Ages Eligible for Study

45 years to 69 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Description

Inclusion Criteria:

  • Women aged 45-69, according to the target age of the screening centres involved;
  • New invited women in mammography screening programme.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
EXPERIMENTAL: Decision-aid
Other: Decision-aid
Web platform with a multilevel information and an aid for the decision to be taken. The content is splitted in 16-20 screens; each screen contains the answer to a common question (i.e. What is mammography screening? What are its benefits and harms? What results can be expected from the participation to mammography screening? What is breast cancer?). The information covers also controversial topics as overdiagnosis, overtreatment and the disagreement among scientists about harms and benefits' quantification.
ACTIVE_COMPARATOR: Standard information
Other: Standard information
Web platform with a standard brochure. This standard brochure represents a combination of the best information available from the three participate centre' brochures.

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
Number of Participants With Adequate Knowledge
Time Frame: 7-10 days
Knowledge will be measured using a questionnaire structured in 13 questions with multiple choice answers, with 2 to 4 options. Ten questions will be qualitative and 3 will be numerical. A score of 8 out of 13 (about 60%) or higher would be considered "adequate knowledge".
7-10 days
Attitude
Time Frame: 7-10 days
Attitude will be measured through a scale of 6 items with 5 response options from 1 to 5, with a total score from 6 to 30. The investigators set the threshold for a positive attitude at 24 and consequently the score <24 point a negative attitude.
7-10 days
Intention
Time Frame: 7-10 days
Intention will be measured using 1 item with 5 responses: Definitely will, Likely to, Unsure, Not likely to, Definitely will not. The investigators classified "definitely will" and "likely to" as positive intentions.
7-10 days

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
Participation Rate to the Breast Cancer Screening Programme
Time Frame: 15-60 days
Participation rate to the breast cancer screening programme will be assessed as a percentage of participants who actually participate, both in intervention and in the control group.
15-60 days
Satisfaction With the Information Measured Using 8 Items With Three Points Scale
Time Frame: 7-10 days
Satisfaction with the given information will be measured using 8 items with three points scale.
7-10 days
Number of Click on the Homepage
Time Frame: Through study completion, an average of 10 days
Number of click on the Homepage will be assessed trough Pickwick software.
Through study completion, an average of 10 days
Number of Times Web Platforms Were Accessed
Time Frame: Through study completion, an average of 10 days
Number of Times Web Platforms were Accessed assessed trough Pickwick software

Number of Pages Visited on the Web Platforms
Time Frame: Through study completion, an average of 10 days
