Traditionally, an excess of interpersonal dependency has been used to
characterize disturbed interpersonal relationships in adults. This app
roach stands in sharp contrast to that of attachment theorists who con
ceptualize attachment as functionally distinct from dependency. Attach
ment theory focuses on anxious attachment in the definition and dynami
cs of disturbed adult interpersonal relationships. The purpose of this
study was to examine the relevance of anxious attachment to the diffe
rentiation of psychiatric outpatients from nonpatients. Empirically, t
hree scales (feared loss of the attachment figure, proximity seeking,
and separation protest) measure the components of anxious attachment a
s defined by Bowlby. The scales were administered to two research samp
les. Sample 1 was composed of 136 respondents to a survey within the C
algary community. Sample 2 consisted of 110 psychiatric outpatients dr
awn from the psychotherapy clinic of the Calgary General Hospital. The
results indicate that the three components of anxious attachment offe
r a clinically relevant system for differentiating between psychiatric
outpatients and nonpatients. Of these three components, feared loss h
as the predominant effect. The implications of this finding for the de
lineation of disturbed interpersonal relationships in adults is discus
sed.
