The present study investigates why some women, before and during delivering
, request peridural analgesia or, on the contrary, refuse it. On the basis
of a literature review and of an empiricial study involving 57 women, a psy
chological differentiation is attempted to discriminate users from non-user
s of peridural analgesia. Pain perceptions, health locus of control, when i
nternal (IHLC), family and couple adaptability appear to be discriminating
factors. Our results indicate a higher chance locus of control (externality
) in non-users then in users, as well as a more rigid couple functioning. T
he incidence of Internal Health Locus of Control of pain perception is outl
