About this study

In this study, the goal is to identify the prevalence and predictors of reactance, self-exemption, disbelief, and source derogation in reaction to evidence about mammography benefits and harms, and consequences for decision-making and trust. Research has not yet systematically identified the proportion of women who respond negatively (vs. positively) to evidence about the benefits and harms of mammography screening, or attempted to explain these responses by examining theory-driven predictors. The Investigator will develop and conduct a probability-based nationally representative survey in which mammography evidence is communicated using current best practices in risk communication. The Investigators will identify theory-driven predictors of negative and positive responses to that evidence, and identify consequences of these responses for screening decision-making and trust.

Treatment and study plan

Decision aid

Behavioral

Mammography screening decision aid for women in their 40s with information about screening guidelines, breast cancer mortality reduction, false positives, overdiagnosis, and a personal breast cancer risk estimate.

Primary outcomes

  1. Reactance

    Time frame: 24 hours

    In response to mammography evidence, feeling that the information is manipulative or biased. 4 questions total, each on a 7 point Likert scale, with mean scores that range from 1 to 5. Higher mean scores reflect greater reactance.

  2. Disbelief

    Time frame: 24 hours

    In response to mammography evidence, feeling that the evidence is not accurate or believable. 4 questions total, each on a 5 point Likert scale, with mean scores that range from 1 to 5. Higher mean score reflects more disbelief in the information.

  3. Source Derogation

    Time frame: 24 hours

    In response to mammography evidence, feeling that the source of the evidence is not trustworthy or competent. 4 questions total, each on a 5 point Likert scale, with mean scores that range from 1 to 5. Higher mean score reflects more source derogation.

  4. Self Exemption

    Time frame: 24 hours

    Feeling that mammography evidence is not relevant to oneself.34 questions total, each on a 5 point Likert scale, with mean scores that range from 1 to 5. Higher mean scores indicate greater belief that the information is not self relevant.

  5. Screening Intentions

    Time frame: 24 hours

    Intentions to engage in mammography screening. Options will include: 1. I am planning to start/continue having regular mammograms this year. 2. I am planning to wait until I'm older but before age 50 to have my first/next mammogram. 3. I am planning to wait until I am 50 to have my first/next mammogram. 4. I am not planning to have a mammogram in the future at any age

Secondary outcomes

  1. Medical Mistrust Scale (Eaton et al., 2015)

    Time frame: 24 hours

    6 question scale that assesses mistrust in healthcare providers. Calculated as mean trust (range 1-low trust to 5-high trust). Assessed both pre and post receipt of screening decision aid to evaluate change
