PHILADELPHIA (CBS) – A new survey released Thursday says young adults, between 18 and 33-years-old, are more stressed than any other generation.

USA Today says the online survey was conducted in August 2012 by Harris Interactive for the American Psychological Association and was taken by 2,020 U.S. adults (18 and older).

Results of the survey say the average stress level of adults in 2012 was 4.9 on a 10-point scale, where one means “little or no stress” and 10 means “a great deal of stress.”

The survey found that the stress level for Millennials, adults aged 18-33, was 5.4 with 39 percent saying their stress increased during the past year and 52 percent saying that it has kept them up at night. The top two causes of their stress are work and money.

Millennial survey participants also reported, more than any other group, that a health care provider told them they have depression or an anxiety disorder.
