Cognitive theories of the etiology of depression in adulthood have rec
eived widespread acceptance. To date there is little evidence of the r
ole of cognitive distortion in the etiology of depression among adoles
cents. This study was conducted to determine whether or not cognitive
disortion differentiates depressed adolescents from non-depressed adol
escents. The Dysfunctional Attitude Scale, a measure of cognitive dist
ortion, was administered to three groups of adolescents: clinically de
pressed; non-depressed with non-psychotic psychiatric disorders; and a
non-clinical group of adolescents without psychiatric disorders. A su
bset of the depressed patients was re-administered the scale after the
y had clinically recovered from the depressive episode. The depressed
adolescents had significantly greater cognitive distortion than the no
n-depressed adolescents. Remission of the depressive disorder was asso
ciated with a significant reduction in cognitive distortion, although
the level of cognitive distortion was still significantly higher than
normal.
