Given that university faculty members and supervisors practicing in th
e community have been involved in at least one research supervisor-gra
duate student relationship, it is surprising that so little attention
has been paid to the ethical issues involved in such relationships. In
deed, as a student and her or his graduate research supervisor may be
involved in a close working relationship for many years, it is underst
andable that several opportunities can arise that could be considered
dual or multiple relationships. Examples of such relationship issues d
iscussed in this article include authorship matters, favoritism or ine
quitable treatment of students, and sexual relationships. Depending on
the nature of the relationship, the impact on students can be quite s
evere; although, the effects on students have not been adequately stud
ied. Existing ethical guidelines do not provide enough guidance in thi
s area where students are in a position of diminished power with respe
ct to the supervisor. Following the discussion of relationship issues,
we suggest extensions of current guidelines to deal with these issues
