Childhood Abuse Delays Recovery from Depression In Adults
University of Toronto investigators examined a range of factors associated with remission in a sample of 1,128 depressed Canadian adults, drawn from the National Population Health Survey.
Depressed individuals were followed every other year until remission occurred, for up to 12 years.
“Our findings indicated that most people bounce back. In fact, three-quarters of individuals were no longer depressed after two years,” reported co-author Tahany M. Gadalla, Ph.D.
However, not everyone recovered at the same rate.
“Early adversities have far-reaching consequences. The average time to recovery from depression was 9 months longer for adults who had been physically abused during their childhood and about 5 months longer for those whose parents had addiction problems” said lead author Esme Fuller-Thomson, Ph.D.
“Numerous studies have shown that childhood abuse and parental addictions make individuals more vulnerable to depression,” said co-author and M.S.W. graduate Marla Battiston.
“Our research highlights that these factors also slow the recovery time among those who become depressed.”
Although this study could not determine why childhood adversities are associated with poor depression outcomes, the researchers speculate that negative experiences may interrupt the normal development of the hypothalamic–pituitary–adrenal (HPA) axis, which affects stress regulation.
“In many studies, adult depression has been characterized by HPA axis hyperactivity,” said co-author and recent Ph.D. graduate, Sarah Brennenstuhl.
“This link is an important avenue for future research.”
The study is published in the journal Social Psychiatry and Psychiatric Epidemiology.
