CHARLOTTESVILLE, Va. (CBS19 NEWS) -- Researchers say Black women are more likely to suffer from insomnia than other groups, but there may be something to help.

At the University of Virginia School of Medicine, they created an online sleep intervention program called SHUTi and tested it on more than 300 Black women, finding it was much more effective than a traditional sleep education program.

The virtual sleep treatment provides cognitive behavioral therapy, which addresses thoughts and behaviors that prevent sleep.

Researchers made two versions of the app: a standard version and one specifically tailored to Black women.

They found that when the app was culturally focused, the women were more likely to complete the program. The study found that 78 percent of the women given the culturally-tailored version completed the program, compared to about 65 percent of those using the standard version.

"I think that the key takeaway is that tailoring really can be a critical factor in keeping patience engaged with this kind of treatment," said Lee Ritterband, PhD, the director of the UVA Center for Behavioral Health and Technology. "We have an opportunity to utilize this technology and make treatment available remotely. "

Other studies indicate Black women suffer from excessive stress, which leads to insomnia.

The findings have been published in the scientific journal JAMA Psychiatry.
