The 27-year-old also won world gold in Moscow in 2013, a year after clinching Olympic gold in London.
Eaton took the award despite sprint superstar Usain Bolt clinching a fifth treble gold showing in a major championships in Beijing.
The Jamaican star had performed the same feat at the 2008 and 2012 Olympics in Beijing and London, and world championships in 2009 and 2013 in Berlin and Moscow.
Dibaba, 24, is the current world record holder in the women's 1500m and holds three further world records indoors.
Dibaba, the sister of three-time Olympic champion Tirunesh, claimed gold in the 1500m in the Beijing worlds.
The IAAF normally holds a star-studded season-ending awards gala in Monaco, but that was cancelled this year following allegations of corruption at the highest echelons of world track and field's governing body.
