The purpose of this study was to explore the breast restoration decisi
on-making patterns used by women who opted to have their breast cancer
treated by mastectomy, Sixty-four women wearing external breast prost
heses and 31 women with breast reconstructions were interviewed, Modif
ied versions of Simon's notion of ''bounded rationality'' and Janis an
d Mann's conflict model provided the conceptual scaffolding for the st
udy. Five breast restoration decision-making patterns emerged from the
analysis of the interview data: (a) Enlightened (actively seeks infor
mation, considers positive and negative aspects, and demonstrates deli
beration on the alternatives), (b) Contented (passively accepts minimu
m information on alternatives because of a preference toward a particu
lar type), (c) Sideliner (uncritically adopts any alternative that is
easy and simple to implement), (d) Shifter (gives over the decision to
others), and (e) Panic-stricken (can make no rational decision on alt
ernatives). In the prosthesis group, the major pattern used was the Si
deliner, and in the reconstruction group it was the Contented. None of
the participants used the Enlightened pattern. The data indicated tha
t there was no evidence of active information-seeking behavior or deli
beration on the alternatives as part of the women's decision-making pr
ocess. The findings suggest a need for a registered nurse oncology spe
cialist to be accessible to women during the period when decisions reg
arding breast restoration are made, This professional has the knowledg
e to interact effectively with these women and serve as their advocate
during the decision-making process. Implications for professional pra
ctice and a model for competent breast restoration decision making are
presented.
