简要总结
RATIONALE: Genetic counseling may work as well over the telephone as it does in-person. It is not yet known whether genetic counseling by telephone is more effective than standard (in-person) genetic counseling in women at risk of carrying the BRCA1 or BRCA2 mutation.
PURPOSE: This randomized phase III trial is studying telephone-based genetic counseling to see how well it works compared to standard (in-person) genetic counseling in women at risk of carrying the BRCA1 or BRCA2 mutation.
详细描述
OBJECTIVES:
Primary
- Compare the impact of telephone genetic counseling (TGC) versus standard genetic counseling (SGC) on utilization of BRCA1/BRCA2 testing in women at risk of carrying the BRCA1/BRCA2 mutation.
- Compare the relative efficacy of TGC versus SGC on satisfaction with the counseling process, informed decision making, psychosocial distress, and quality of life.
Secondary
- Identify participant characteristics that predict differential response to TGC.
- Explore the mechanisms by which TGC or SGC impact distress and quality of life.
