Some patients enter psychiatric treatment with clear cases of both maj
or depression and alcoholism. While assumptions are often made about t
he relationships of these two conditions, little empirical evidence ex
ists on the effects of sustained remissions in alcoholism on sustained
remissions in depression. 127 patients with both disorders at treatme
nt entry were studied over a 5-year period. Survival analyses with tim
e-dependent covariates indicating alcoholism status were used to inves
tigate remissions and relapses in major depression. Remission in alcoh
olism strongly and significantly increased the chances of remission in
depression and were also related to reduced chances of depression rel
apse, although at a weaker level.
