Ad. Simons et al., TOWARD AN INTEGRATION OF PSYCHOLOGIC, SOCIAL, AND BIOLOGIC FACTORS INDEPRESSION - EFFECTS ON OUTCOME AND COURSE OF COGNITIVE THERAPY, Journal of consulting and clinical psychology, 63(3), 1995, pp. 369-377
The present study attempted to integrate key variables from 3 major do
mains of theory in depression (cognition, stress, and psychobiology) t
hat are typically studied separately in analyses of course and respons
e to cognitive therapy. Dysfunctional attitudes, negative life events,
or sleep electroencephalogram were assessed in 53 outpatients before
treatment with cognitive therapy. High levels of dysfunctional attitud
es were found to be associated with poorer response to treatment but n
ot for those patients who had experienced a severe negative life event
. Examination of the length of time required to achieve remission reve
aled an effect for rapid eye movement (REM) latency as well as the int
eraction between REM latency and life events. These results are discus
sed in terms of the promise of integrative research in the study of de
pression and its treatment.
