duration of the disorder might have varied from one patient to
another. Third, as this was a retrospective chart review, the
researchers were unable to account for cognitive impairments
that might have occurred during the treatments. Therefore, it is
unknown whether cognitive deficits led to discontinuation of
the full series prior to reaching maximal medical improvement
for some patients. Despite the observed results of each patient,
even if CUDOS (Zimmerman et al., 2008) scores displayed im-
provement, it is unknown if the patient did truly meet maxi-
mal medical improvement. Therefore, this study cannot con-
clude that patients overall reached maximal medical improve-
ment. Alternatively, it can be concluded that patients, overall,
showed improvement after ECT treatments.
Fourth, the selection process delimited the study by selecting
patients who were diagnosed with a type of depression and
received a minimum of four ECT treatments in a series. How-
ever, this study did not control for comorbid psychiatric disor-
ders. Therefore, it is unknown if differences in progress were
due to comorbidity. This could be the case as Afifi (2005) noted
that patients with MDD commonly have a comorbid anxiety
disorder. Lastly, this study did not control for medication dur-
ing ECT treatment. Due to the nature of the treatment, it was
difficult to control for medication as each patient had different
circumstances medically and psychologically. Therefore, reco-
mmendations for future ECT studies include: controlling for co-
morbidity and medication, obtaining a larger sample size to
categorize patients according to medication type and dosage.
Conclusion
In conclusion, the findings of this study support the efficacy
of ECT in treating depression. More improvement was shown
in female patients than male patients. Lastly, the CUDOS has
shown to be a simple and effective self-report measure in as-
sessing progress of depression including complex treatments,
such as ECT. The measure is also helpful in providing a clear
and objective approach to measure treatment outcome.
