This study examined the association of dispositional self-focused attention
to mood rated at the time of a negative social interaction in 100 employed
, middle-age adults using experience sampling methodology. Results revealed
that a self-focusing style was associated with higher negative mood and lo
wer positive mood at the time of a negative social interaction during 3 day
s of everyday activities. Women who were chronically self-focused were part
icularly vulnerable to these negative social interactions in the daily envi
ronment; they were more likely than men to report lower positive mood durin
g the interaction. In addition, 30 minutes after the negative social intera
ction, self-focused individuals with higher preexisting levels of depressiv
e symptoms continued to report higher levels of negative mood and lower lev
els of positive mood relative to individuals who were not self-focused and
did not report higher depressive symptoms. These results provide support fo
r the role of self-focused attention in the etiology and maintenance of neg
ative moods.
