Increasingly, it is recognized that people should make informed decisions about whether, when and how often to receive various cancer screening tests. For some cancers, such as colorectal cancer, there also may be choices about which cancer screening test to obtain. Yet, few interventions have been developed and tested to facilitate informed decision making (IDM).
Personally Relevant Information about Screening Mammography (PRISM) is a tailored decision-aid intervention developed specifically for women in their 40s and 50s.  The program aims to increase women's knowledge, the accuracy of their risk perceptions about, and mammography use.  PRISM is based on the Transtheoretical Model and Precaution Adoption Process Model.  The intervention is comprised of tailored print materials and telephone counseling to help women weigh the risks and benefits of mammography and reduce decisional conflict. The data are based on their responses to a telephone interview.  But other approaches could be used to obtain data for creating the tailored interventions. Print materials are tailored on the basis of about 20 variables, e.g., benefits and limitations of mammography, barriers to screening, and risk factors for breast cancer such as current age, age of menarche, previous breast biopsy, and personal and family history of breast cancer.  Telephone counseling answers questions and concerns and facilitates discussion about breast cancer and mammography.
Implementation Guide

The Implementation Guide is a resource for implementing this evidence-based program. It provides important information about the staffing and functions necessary for administering this program in the user's setting. Additionally, the steps needed to carry out the program, relevant program materials, and information for evaluating the program are included. The Implementation Guide can be viewed and downloaded on the Program Materials page.

This program uses the following intervention approach for which the Community Preventive Services Task Force finds insufficient evidence: interventions promoting informed decision making for cancer screening (Informed Decision Making). Insufficient evidence means the available studies do not provide sufficient evidence to determine if the intervention is or is not effective. This does not mean that the intervention does not work. It means that additional research is needed to determine whether the intervention is effective.

Delivery time varies by intervention. By mail, women receive a tailored booklet 2 to 3 weeks after a baseline telephone survey and a newsletter 2 to 3 weeks after a 12-month follow-up telephone survey.  The phone surveys are approximately 30 minutes long but would be shorter if done as part of service delivery rather than research. Moreover, not all questions need to be asked if done outside of research.  Two weeks after women get the print materials, they receive a 5-7 minute counseling call.  Telephone counselors were trained for about 3 weeks.

Study participants were North Carolina women aged 40 to 44 years and 50 to 54 years.  82% were White; 15% were Black; and 3% were classified as "Other". 80% were married; and 40% had at least a college education.  However, there is no reason to believe the interventions would not be acceptable to and appropriate for women in their 60s. And there have not been differential responses by race/ethnicity.

The intervention is suitable for implementation in the home. In fact, this is the preferred setting.
Required resources include two sample booklets, a sample newsletter, and the first- and second-year telephone counseling protocol and script for participants in their 40s and 50s.  The baseline and 12- and 24-month surveys are also required but outside the research setting, the questions could be reduced by about half to include only those used for tailoring.   In addition, two fact sheets regarding how self-report variables can be used to develop individually tailored print materials like the PRISM booklet and newsletter are provided for review. Costs associated with the program are not provided.

Participants (N = 1287) recruited for the study included women aged 40 to 44 years and 50 to 54 years who were also enrolled by a large insurance carrier.  Women were stratified by age and mammography use, and randomized to receive usual care (UC), tailored print materials (TP), or tailored print materials plus tailored telephone counseling (TP+TC).  Usual care was the standard information sent by the insurance carrier and included a mailed mammography reminder letter sent on the woman's birthday and letters to providers identifying their patients in need of mammograms.  In addition to usual care, TP women received a tailored booklet 2 to 3 weeks after completing baseline surveys, and a tailored newsletter 2 to 3 weeks after completing the 12-month survey.  Women assigned to the TP+TC group also received a brief counseling call approximately 2 weeks after the booklet and newsletter were sent.  Print materials were tailored according to responses from baseline and 12-month surveys.  Women were interviewed again by phone at the 24-month follow-up. This last interview was for research purposes.

Results indicated:

  • Women in the TP+TC condition had more accurate perceptions of their breast cancer risk at 12 and 24 months than women in the TP or UC conditions.

Graph of Study Results

  • Women in the TP+TC condition had greater knowledge of mammography efficacy at 12 and 24 months than women in the TP or UC conditions.
  • The effect on mammography use was significant in bivariate relationships although the differences were more modest in multivariate analyses.  At 12 and 24 months, 18% to 20% of the UC group, 13% to 16% of the TP group, and 22% to 24% of the TP+TC group had mammograms. The ranges reflect different windows for reporting mammography use.
