Theory-based behavior change intervention to increase uptake of risk-reducing salpingo-oophorectomy in women with a BRCA1 or BRCA2 pathogenic variant: The PREVENT randomized controlled trial.

ABSTRACT:

Objective

To evaluate the effect of a theory-based behavioral intervention delivered by genetic counselors on the uptake of risk-reducing salpingo-oophorectomy (RRSO) at 12 and 24 months by women with a BRCA1 or BRCA2 pathogenic variant (PV) compared to women who received usual care.

Methods

In this two-arm, multi-site randomized controlled trial participants were randomized to receive a theoretically-guided behavioral telephone intervention or usual care. Outcome data were collected at 12 and 24 months. Participants in the usual care arm were offered the intervention after 12 months.

Results

Data on 107 participants were included in the analysis. There was no significant difference in the proportion of women who had a RRSO by 1 year (28.6%- intervention; 22.9%- usual
