Previous investigations have found that older adults utilize mental health services at very low rates, substantially lower than those documented for younger individuals.
For the recent study, Bradley Karlin, Ph.D., and colleagues examined changes in depression and quality of life in both younger and older adults using a large, diverse national sample of veterans.
“Untreated depression in older adults is associated with poorer quality of life, significantly increased mortality, increased suicide rates, exacerbation of and/or delay in recovery from medical illness, and considerable economic, social, family, and overall societal costs,” the authors state.
The investigators believe this evaluation demonstrates the promise and effectiveness of cognitive-behavioral therapy for depression (CBT-D).
The study also provides encouragement for older adults to seek treatment.
Karlin’s team analyzed the effectiveness of CBT-D among 864 veterans — 100 were age 65 and above and 764 were age 18 to 64 — seeking treatment within the Veterans Health Administration.
The CBT-D treatment protocol was developed specifically for veterans and military service members and is intended to be administered in approximately 12 to 16 individual psychotherapy sessions.
Approximately 68 percent of both older and younger patients completed all sessions or finished early due to symptom relief.
Of those, there was an average overall reduction of close to 40 percent in Beck Depression Inventory-II scores — used to assess the severity of depression — from the early phase to the later phase of treatment.
The project was supported by Mental Health Services within the U.S. Department of Veterans Affairs Central Office.
