Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Breast Cancer Other: Decision-aid Other: Standard information Not Applicable

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.

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.




Primary Outcome Measures :
  1. Knowledge measured using a questionnaire [ 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".

  2. Attitude measured through a scale [ 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.

  3. Intention measured using 1 item with 5 responses [ 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.


Secondary Outcome Measures :
  1. 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 women who actually participate, both in intervention and in the control group.

  2. 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.

  3. Number of pages visited [ Time Frame: Through study completion, an average of 10 days ]
    Number of pages visited on the web decision aid will be assessed trough Pickwick software.

  4. frequency of access on the web platforms [ Time Frame: Through study completion, an average of 10 days ]
    The frequency of access on the web decision aid will be assessed trough Pickwick software

  5. Level of detail reached on the web platforms [ Time Frame: Through study completion, an average of 10 days ]
    Level of detail reached on the web platforms on the web decision aid will be assessed trough Pickwick software.

  6. Decisional conflict using Decisional Conflict Scale-SURE version [ Time Frame: 7-10 days ]
    Decisional conflict will be assessed using the validated and widely used Decisional Conflict Scale-SURE version, consisted in four-item scale.
