About this study

The no show rate for mammography screening is high among Navajo women. One barrier to preventive screening is a lack of cancer literacy including low knowledge and cultural attitudes (e.g., fatalism) about screening. The investigators will examine the potential feasibility and acceptability of a cancer literacy intervention for families of Navajo women who have no showed for three consecutive times to mammography screening who have never or rarely been screened in the past.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

In Phase 1, we will recruit 17 Navajo women for individual interviews (n=5) and focus groups (n=12) to adapt our measures. Eligibility criteria are:

  1. aged 40 years or older and
  2. provides written informed consent. We chose to develop our measures based on feedback from the general community of women who are screening eligible instead of matching the inclusion/exclusion criteria to that used in the formative evaluation of the intervention (Phase 2). This will enhance our ability to use the Cancer Literacy Measure and other assessments in subsequent breast cancer prevention and control studies.

In Phase 2, we will recruit a total of 40 patient-family member pairs. To be eligible for the study, the NNBCCPP patient must:

  1. be aged 40 years or older,
  2. provide written informed consent,
  3. be referred to the NNBCCPP as a "no-show" for mammography screening after three scheduling attempts,
  4. have no prior history of mammography screening,
  5. have no prior history of breast cancer, and
  6. can identify a female family member or other individual who resides in or near the home who could participate in the project.

In addition, the family member must:

  1. be female,
  2. aged 18 years or older,
  3. be fluent and literate in Navajo,
  4. be interested and able to participate, and
  5. provide written informed consent.

Exclusion Criteria:

Phase 2: History of breast cancer or mammography screening
