Drawing from self-affirmation theory (C. M. Steele, 1988) and L. L. Martin
and A. Tesser's (1989, 1996) theory of ruminative thinking, the authors hyp
othesized that people stop ruminating about a frustrated goal when they can
affirm an important aspect of the self. In 3 experiments participants were
given failure feedback on an alleged IQ test. Failure feedback led to incr
eased rumination (i.e., accessibility of goal-related thoughts) compared wi
th no-failure conditions (Studies 1 and 2). Rumination was reduced when par
ticipants could self-affirm after failure (Studies 1 and 2) or before failu
re (Study 3). In Study 3, self-affirmation led to increased positive affect
on a disguised mood test and more positive name letter evaluations. Moreov
er, the obtained increase in positive affect mediated the effect of self-af
firmation on rumination. It is concluded that self-affirmation may be an ef
fective way to stop ruminative thinking.
