Background: Previous research has found a significant positive relatio
nship between dependency and level of depression. The aim of the prese
nt study, using factor analysis method, is to test the hypothesis that
dependency and depression constitute distinct dimensions. Methods: In
a sample of 202 university students, a correlation matrix comprising
items from both the Interpersonal Dependency Inventory and the abridge
d form of the Beck Depression Inventory was analysed using a principal
components analysis followed by an orthogonal varimax rotation. Resul
ts: Evidence for a four-factor solution was found with almost no overl
ap of the significant factor loadings for the items from each scale, a
nd with the factors corresponding closely with their respective constr
uct. Conclusion: The findings support the view that depression and dep
endency constitute different constructs. Limitation: The results must
be confirmed on clinical and heterogeneous nonclinical samples. Clinic
al relevance: The independency between depression and dependency could
lead to different therapeutic strategies notably in 'socially depende
nt' type of depression. (C) 1998 Elsevier Science B.V.
