This study examined several tenets of the response styles theory of de
pression (RST Nolen-Hoeksema, 1991) and its generalizability to adoles
cent populations. Using a short-term longitudinal design, we evaluated
whether response styles (i.e., ruminative and distractive responses t
o depressed mood) predict depression severity and whether they do so b
eyond the effects attributable to other cognitive variables. Anxiety w
as also assessed to investigate the specificity of RST to depression.
Finally, we investigated gender differences in response style and whet
her these differences account for the gender difference in depression
that emerges during adolescence. Self-reported affective symptoms and
cognitive predictors (attributional style and private self-consciousne
ss) were assessed in 397 adolescents. Results indicated that response
style variables predicted concurrent and future (6-week followup) mood
scores beyond effects accounted for by other cognitive variables. Rum
ination was less specific to the prediction of depression than was dis
traction, but only rumination predicted future depressed mood. Althoug
h girls reported more rumination, controlling for response style did n
ot eliminate the gender difference in depression. Results are discusse
d with respect to the current status of RST, including construct measu
rement and its relevance to adolescent depression.
