The self-concept and causal attributions are both centrally implicated in p
sychological disorders including depression and paranoia. In two investigat
ions of the dynamic relationships between causal attributions and self-repr
esentations, nonpatient participants completed questionnaires derived from
Higgins' (1987) Self-Discrepancy Theory before and after completing a measu
re of causal attribution. In Study 1, consistent with cognitive models of d
epression, external attributions for negative events were associated with r
eductions in self-actual: self-ideal discrepancies. Study 2 revealed signif
icantly different effects on self-discrepancies of three types of causal at
tributions. Internal attributions led to increased self-actual:self-ideal d
iscrepancies as well as increased discrepancies between self-perceptions an
d the believed views of others about the self (self-actual: other-actual di
screpancies). External situational attributions led to no changes in either
self-actual:seif-ideal or self-actual: other-actual discrepancies. Externa
l personal attributions led ro no changes in self-actual: self-ideal discre
pancies bur increased self-actual: other-actual discrepancies. These findin
gs point to the value of distinguishing between different kinds of external
attributions. They show that self-representations and causal attributions
are closely coupled cognitive domains. The results also suggest that parano
id ideation might be specifically associated with external-personal attribu
tions for negative events.
