Abstract: Major depressive disorder (MDD) profoundly affects social func-
(Weissman, 2000). A small number of studies have investigated long-
tioning, including the ability to enjoy social activities with peers, friends, and
term social functioning impairments during or after treatment using
family members. We sought to compare changes in social functioning and
antidepressants; these suggest that long-term impairments in social

in WSAS Item 3 and Individual QIDS-SR Items or Total QIDS-SR
also administered using the IVR system. Scores for individual items
range from 0 to 3; the score for the entire instrument ranges from0 to 27.
Patients who had QIDS-SR and WSAS scores for entry and exit
(n = 1846) were included in this post hoc analysis. We compared
the change (exitYentry) in the social activities item of the WSAS (item
3) to the change in individual items of the QIDS-SR. The Pearson
product-moment correlation was computed between the change inWSAS item 3 and the change in each QIDS-SR item (for a total of
16 separate correlations); for these correlations, > was adjusted using
the Bonferroni correction, yielding an > of 0.003 (= 0.05/16). In
addition, the Pearson product-moment correlation was computed be-
tween the change in WSAS Item 3 and the change in total QIDS-SR
score. Proportion of variance was calculated as the square of Pearson r.
The STAR*D level 1 analyzable sample of 2876 has been
reported elsewhere (Trivedi et al., 2006a). Of these 2876 patients,
1846 had both baseline and exit assessments of the WSAS. Table 1
shows the baseline characteristics of the 1846 patients included in this
analysis; these were not significantly different from the characteristics

Rapaport et al. (2005) compared baseline symptom measures
with baseline quality of life measures in an array of mood and anxiety
disorders and found that ‘‘illness-specific symptoms’’ accounted for
only a small to modest proportion of the variance in quality of life,
leading them to conclude that quality of life is a ‘‘related but semi-
independent component of DSM-IV syndromes’’ (p. 1176). In thisstudy, we sought to determine the extent to which improvements in
social functioning, as opposed to the broader concept of quality of
life, were related to improvements in MDD symptoms.
In this large (n = 1846), real-world sample of outpatients,
all QIDS-SR items (except for the infrequently reported increased
appetite and weight gain) were significantly correlated (Bonferroni-
corrected > = 0.003) with change in the social activities item of the
WSAS (Table 2). However, even the most highly correlated items
(sad mood, concentration/decision making, involvement, and energy/
fatigability) individually account for only 16% to 23% of the variance
in social functioning. The less highly correlated items (sleep onsetinsomnia, self-outlook, suicidal ideation, psychomotor slowing, mid-
nocturnal insomnia, decreased appetite, psychomotor agitation, early
morning insomnia, hypersomnia, decreased weight, and increased
appetite) individually account for only 1% to 10% of the variance.
Even the change in total QIDS-SR score accounted for only 34%
