简要总结
Using mixed methods, investigators will conduct a multicenter partially randomized preference noninferiority trial with high-risk English-, Spanish-, and Cantonese-speaking patients assigned by (1) patients´ preference or (2) randomization to three counseling modes: (a) in-person; (b) phone; or (c) video conference. A total of 600 patients will complete counseling and 540 will complete the final survey. Baseline and post-counseling surveys will use validated measures (adapted for literacy and language) of study outcomes. All counseling sessions will be audio-taped. A sample of 90 tapes will be analyzed for counseling content and to identify 30 participants for in-depth interviews and analysis triangulating all forms of data. Genetic counselors will be interviewed in depth to elicit their perceptions of the strengths and limitations of each counseling mode.
详细描述
Specific Aims.
The specific aims of this mixed methods study are:
Aim 1. Compare the effectiveness of 3 modes of genetic counseling in a diverse sample of patients at high risk for HBOC in 3 public hospitals. Conduct a multicenter partially randomized preference noninferiority trial with high-risk patients assigned by (a) randomization to three counseling modes: in-person, phone, video conference; or (b) patients´ preference. Utilize validated measures of study outcomes adapted as needed for literacy and language. Recognizing that some potential participants may have a strong preference for one counseling mode, after explaining the study design and obtaining informed consent, participants will be asked if they have such a preference. Those who do will be offered that mode, and those who do not will be randomized. Randomization will be stratified according to hospital and personal history of breast cancer in order to ensure that there is no imbalance in important factors that may be associated with outcome.
Aim 2. Explore inductively and qualitatively variation in patients' genetic counseling experiences and understandings, genetic counselor satisfaction and perceptions, counseling session similarities and differences, and implications of organizational context across three modes of genetic counseling.
Aim 3 employs inductive, qualitative methods to explore in depth the cases of 30 patients using their pre- and post-counseling survey responses, audio tapes of their counseling session, and in-depth interviews to explore questions common to all respondents and those specific to what was learned about the individual from the other data sources. In-depth interviews will also be conducted with genetic counselors.
