Behavioral therapy, physical strengthening may prevent disability for minority elderly
Improving coping skills and physical strengthening can significantly improve functioning and mood in racial and ethnic minority and immigrant older adults, according to a new study published in the American Journal of Geriatric Psychiatry.
Researchers at the disparities research unity at Massachusetts General Hospital (MGH) in Boston developed a new disability prevention intervention, Positive Minds-Strong Bodies (PMSB), which was examined in the randomized controlled trial. Researchers developed the PMSB intervention to meet the needs of racial and ethnic minority and immigrant older adults who are greater risk for disability yet often lack culturally competent health services. The PMSB intervention consists of 10 individual sessions of cognitive behavioral therapy concurrently offered with 36 group sessions of strengthening exercise training over six months.
To test the effectiveness of PMSB, the researchers conducted a randomized controlled trial of 307 participants, funded by the National Institute on Aging and the National Institute of Mental Health. The MGH team collaborated with community-based organizations in Massachusetts, New York, Florida, and Puerto Rico serving minority elders, where data was collected between May 2015 and March 2019.
The PMSB intervention was delivered to English, Spanish, Mandarin, and Cantonese-speaking adults 60 years old or above who were not seeking disability prevention services but were eligible based on their elevated mood symptoms and minor to moderate physical dysfunction.
Results at six months showed significant intervention effects, including improved functioning and lowered mood symptoms. These effects were sustained, with days where the person could not perform their usual roles significantly decreasing six months after the intervention, according to the study abstract.
As the number of individuals aged 65 and over rises to 81 million by 2040, nearly 20 percent will suffer from one or more mental health conditions, with mood disorders the most important risk for premature disability. Considering that one third of older adults in the U.S. are expected to belong to racial or ethnic minority groups by 2040, researchers said the disability prevention field desperately needs to provide mental and physical health services that are culturally competent for all older adults. The components of the PMSB intervention are critical steps in the right direction, said researchers.
PMSB is the only intervention of its kind offered by community health workers, or paraprofessionals, to mostly minority and immigrant elders, according to Margarita Alegria, PhD, corresponding author and chief of the disparities research unit at MGH.
"Our study is one of few addressing disability prevention for ethnic/racial minority and immigrant elders in four languages," said Alegria. “The combined intervention significantly improved mood symptoms and functioning in a diverse sample of elders. Participants reported feeling that the culturally tailored intervention made them better understand their problems and how to cope with them, learning skills, and exercise that could help them feel and function better. Our work also addresses the national shortage of a disability prevention workforce by providing evidence for the use of community health workers."
